Safety Warnings, Dangers, Cautions and Instructions
NOTICE. This unit manual is intended for users with basic knowledge and skillset in welding. It is your responsibility to make certain that the use of this welder is restricted to persons who have read, understand and follow the warnings and instructions in this manual. If you or the operator needs further instruction, contact Everlast welding support at 1-877 755 -9353 ext. 204 or seek qualified professional advice and training.
WARNING! High Frequency (HF) energy can interfere with the operation of pacemakers and can damage pacemakers. Consult with your physician and pacemaker manufacturer before entering an area where welding and cutting equipment is in operation and before using this welder. Some pacemakers have limited shielding. Alert any users or customers of this potential problem.
WARNING! Use approved safety glasses with wrap around shields and sides while welding and working in the weld area or serious eye damage or loss of vision may result. Use a grinding shield in addition to the safety glasses during chipping and grinding operations.
WARNING! When welding always use an approved welding helmet or shielding device equipped with at least an equivalent of a shade 9 or greater. Increase the shade number rating as amperage increase over 100 amps. Inspect helmet for cracks in lenses and in the helmet. Keep lens covers in good condition and replace as necessary.
WARNING! Welding/cutting operations carry inherent risks which include but not limited to possible cuts burns, electrical shocks, lung damage, eye damage and even death. Take all appropriate measures to use proper Personal Protective Equipment (PPE). Always use leather welding gloves, closed toe (preferably reinforced or steel toe leather shoes, and long -sleeved flame resistant clothing (i.e. denim). Do not wear Poly/Nylon blend materials.
DANGER! Welding/cutting poses shock and electrocution risks. Keep this welding equipment dry. Do not weld in the rain or where moisture accumulates. Use dry, rubber soled shoes, gloves and clothing when welding. Do not rest or contact work clamp (ground) when welding. Keep all parts of the body insulated from the part being welded when possible. Do not touch terminals or connections while the unit is on. Consider all parts to be “live” at all times even if no live work is being performed. Do not use frayed welding cables.
CAUTION! Fires are possible but also preventable while welding. Always remove flammable rags, papers, and other materials from the weld area. Keep rags stored in an approved flame proof canister. Keep a fully charged fire extinguisher at hand. Remove any fuels, oils, paint, pressurized spray cans, and chemicals from the weld area. Make sure any smoke/fire detectors are function properly. Do not weld on tanks, drums or barrels, especially if pressurized or sealed. Do not weld on any container that previously held fuel or chemicals. Make sure the weld area is clear of flammable materials such as grass or wood shavings solvents and fuels. Do not wear frayed or loose clothing. Visually inspect and recheck the work area after welding looking for smoldering debris or flames.
WARNING! Welding gas cylinders are under high pressure. Keep all gas cylinders upright and chained to a cart or held safely in a safety holding pen. Never transport gas cylinders in an enclosed car van or other vehicle. Transport gas cylinders securely. Keep all cylinders capped while not in use or during transport. Replace the cap on the cylinder when it is going to be more than 24 hours before use. Do not use or attempt to repair faulty regulators. Never weld on gas cylinders. Keep gas cylinders away from direct sparks.

Safety Warnings, Dangers, Cautions and Instructions
DANGER! Welding and cutting operations pose serious inhalation hazards. Some of these hazards are immediate while others are cumulative in their effect. Do not weld in enclosed spaces or in areas without adequate ventilation. Fumes and gases released in the welding and cutting operations can be toxic. Use fans or respiration equipment to insure adequate ventilation if you are welding in a shop or garage area. Do not weld on galvanized metal under any circumstance. You may develop metal fume fever. Symptoms are similar to lulike symptoms. Seek medical advice and treatment if you are exposed to galvanized welding fumes.
If you experience any eye burning, nose or throat irritation while welding, these are signs that you need more ventilation.
If you feel these symptoms:
· Stop work immediately and relocate work area with better ventilation.
· Wash and clean your face and hands.
· Stop work completely and seek medical help if irritation persists DANGER! Never use brake cleaner or any chlorinated solvent to clean or degrease metal scheduled to be welded or other related equipment in the area being welded. The heating of this cleaner and its residue will create highly toxic phosgene gas. Small amounts of this vapor are harmful and can lead to organ failure and death. If degreasing of a part is necessary, use Acetone or an approved pre- weld cleaner. Use the proper personal protective equipment (PPE) when handling any cleaners/solvents. DANGER! People with pacemakers should consult a physician and pacemaker manufacturer before welding. There is a potential for damage or serious malfunction resulting in death. High Frequency energy (HF)/Electromagnetic Fields generated during welding can interfere with pacemaker signals, even permanently damaging it. Some pacemakers offer some shielding, but restrictions regarding amperage and HF starting of welding arcs may be placed upon the individual. Warn all potential bystanders that they should exit the work area if they have a pacemaker or similar medical equipment before welding. In adverse conditions, severe electrical shock leading to injury or death may occur while using the welder if the user becomes part of the circuit path. Consult with a Physician if a pacemaker is expected to be implanted. DANGER! Never defeat or modify any safety guards or shields. Keep all safety covers and shields in place.
Never place your fingers in or near a fan shroud or insert any object into the fan(s).
DANGER! Do not weld on the gas cylinder. Do not weld near fuel, cleaners, solvents or other flammable materials. Remove these items from the premises before welding. Severe injury or death may result from explosions or fires may occur.

Safety Warnings, Dangers, Cautions and Instructions
CAUTION! Trip Hazards exist around this unit. Cords, cables, welding leads and hoses pose a trip hazard. Be aware of their location and inform others of their location. Tape and secure them so they will stay out of high traffic areas. CAUTION! Welded metal can stay hot long after welding is completed. Burns may occur. Always wear gloves or use tongs/pliers when handling welded or cut metal. Remember the heat from the metal may catch other material on fire. Always have a fire-proof area ready to place welded components until they fully cool. Use soap stone or a metal marking marker to label the metal as “HOT” to serve as a reminder to all present in the area. CAUTION! Welding and cutting operations generate high levels of ultraviolet (UV) radiation which can burn and damage skin and eyes. The intensity is so high that exposed skin and eyes can burn in a few minutes of exposure. Minimize direct skin and eye exposure to this intense form of radiation by using proper PPE and sun screen where appropriate. CAUTION! Do not allow bystanders. Do not allow others without proper Personal Protection Equipment (PPE) suitable for welding to stand in the welding area or to observe welding and welding related activities. If protection is not readily available, use a welding screen to separate the welding area from the rest of the area. If no protection or screen is available, physically exclude them from the welding area by a wall or other solid divider. Keep all pets and young children away from the welding area. CAUTION! Electromagnetic Fields can be generated by this unit and radiate into the work place. The effect of EMF is not fully known. Exercise caution when welding by: NOT draping welding leads (guns/cables) over your shoulders or arms, NOT coiling them around your body, NOT inserting yourself directly between the cables, and by NOT contacting the unit while welding. DO keep the work clamp connected as close as possible to the area of the weld and directly to the object being welded whenever possible.

IMPORTANT: Operating this unit with a generator or other off-grid service.
MINIMUM REQUIRED SURGE WATT RATING: 15,000W MINIMUM REQUIRED THD: 5% or Less
This welder unit should only be operated on a generator certified by its manufacturer to produce clean power. Clean power is equivalent to the quality of household or shop/garage type power. This means the generator must have 5% or less total harmonic distortion (THD) of the Sine wave. If you are unsure of the power output type of the generator, contact the manufacturer of the generator for verification. Do not operate on square wave or modified square wave generators or converters/inverters or damage or malfunction may occur. Damage caused by running this unit off of “dirty” power or modified sine waves may not be readily apparent and can be cumulative in nature. However, damage may present itself immediately. The damage caused by running this unit on “dirty” power usually leaves internal tell-tale signs and damages specific parts.
NOTICE! Operation of this unit with generators not rated by its manufacturer as providing clean power (5% or less THD) is prohibited and will void the warranty. Operation with modified sine wave, or square wave generators and inverters/converters/UPS that do not produce “sine wave” output is prohibited and doing so will also void the warranty. Use only with generators/inverters/converters that produce an equivalent type of sine wave used in shops, homes and “shore” type systems. The generator manufacturer determines the THD rating, not Everlast. Do not assume that a name brand generator, or a “new” generator automatically provides clean power. Price paid does not guarantee a clean power output either. There are multiple brands at various price points capable of producing clean power. Investigate this before purchasing a generator. The manufacturer will usually state that a unit is clean power in the advertising information and will state actual THD. If the manufacturer does not state it, contact the manufacturer directly for a statement concerning actual THD.
WARNING! Do not start or stop the generator with the unit switched on. Never use the generator in ECO mode or an auto-idle mode. Even with a clean power rated generator, this action can damage the unit. Turn the unit on only after full generator R.P.M. has been achieved and the engine is sufficiently warmed up. Closely monitor generator fuel level so that the engine R.P.M doesn’t drop or completely shut down with the unit plugged in. For best practice: do not start or stop the generator with this unit plugged in, even if it is turned off. Unplug the unit before shutting down the generator.
If using with a welder/generator, make sure the manufacturer has determined that the generator portion produces a clean sine wave. Many older models do not. Some newer models use “divided” power between welding and generating and cannot supply the full power to the unit unless the fine current control knob is turned to maximum. Do not use this unit with such welder/generators unless the Power/ fine current control is turned to 100%. Some welder generators do have a separate alternator for generating power. If this is the case, be sure not to weld or load the machine while this unit is in use.
WARNING! Always make sure any generator or welder generator is properly wired and grounded, according to local and national code. Ground the machine per the generator manufacturers instructions to meet code requirements. Improperly grounded generators may damage the machine and more importantly may cause severe injury or death.
240V 1 Phase, 480V 3 Phase Operation
This unit is designed for 240V 50/60Hz single phase operation or 480V 50/60Hz three phase operation. This unit is shipped without a plug and must be wired for the voltage you supply. If your single phase voltage is derived from 208V 3 phase Wye Type power (or your local power company provides measured voltage 216V or less across each hot leg of power), then it is recommended that you install a buck-boost type transformer to provide 240V output. It cannot be operated using all 3 phases of 208, 220 or 240V power. It must be configured for single phase operation. If operating on 480V input, the welder must use all 3 phases of 480V power.
WARNING: Before connecting the unit to the power source make sure the correct voltage has been selected with the rear input voltage selector switch. Failure to do so may damage the welder.

DUTY CYCLE
Duty Cycle is simply the amount of time out of a 10 minute period in which the unit can operate. For example, if this unit has a duty cycle of 60% at maximum output (400 A while operating on 480V 3 phase and 315A while operating on 250V 1phase) means that the unit can be operated for 6 minutes out of 10 minutes at the maximum setting. The unit may be operated be continuously, or intermittently for 6 minutes during the 10 minute period of time while the machine is MIG welding at maximum output. This rating standard (United States) is based on a maximum ambient temperature of 40 C (104°F). Operating at or above this rated operation temperature point, or even at slightly lower temperatures with high humidity readings expect a reduction in duty cycle. In most cases, the duty cycle will increase somewhat as ambient temperature drops. Lowering the operating Amperage to will cause a rise in duty cycle. MIG welding at 315A (480V 3 phase)/250A (240V 1 phase) will increase the duty cycle to 100%. Duty cycle is important to determining what type of work welder is suitable for. However at 35% duty cycle while welding at maximum output, it is rare that manual welding will exceed the duty cycle of the machine, since there is a lot of “in between” work such as grinding, repositioning, cleaning etc. that is often needed between welds. Even though the machine has a 100% duty cycle rating level of 315A/250A on this machine, this does not mean that the welder will operate continuously at this level beyond the 10 minute mark. This is not an infinite rating. Don’t forget that the 100% rating is a rating based off a defined 10 minute period of time. Depending upon the circumstances, the welder could go into overheat mode at the 11 or 12 minute mark even though it is rated for 100% at 10 minutes. Regardless of the duty cycle rating, this unit’s duty cycle is not controlled by a timer. Rather, this unit is equipped with a heat sensor located on a heat sink near the critical power components of the welder. If the operating temperature of the unit is exceeded, welding output will stop and an overtemperature warning light/error code will be displayed on the panel. If a duty cycle event is registered, do not turn the unit off! Allow the welder to continue to run at idle for at least 10-15 minutes until the temperature has fallen enough to reset the sensor and over-temperature warning light. Even if the unit resets, allow the unit to cool for a full 15 minutes, or the duty cycle will be more quickly triggered since the unit resets just below the heat threshold. The fan(s) must continue to run for a full 15 minutes to cool the unit properly after the duty cycle shut down has occurred. After 15 minutes of cooling, you may switch the unit off if you are finished welding. If the unit does not automatically reset after 15 minutes, turn the unit off. Wait for 15 seconds before turning the machine back on. If the unit does not reset, contact technical support for further advice and assistance. As a best practice, when you have completed welding and have been welding continuously for extended periods of time, keep your unit on for 10 additional minutes without welding to allow it to cool. Keeping the unit clean will help maintain the duty cycle of the welder. Removing the cover and blowing it out with dry compressed air, every 3 to 6 months will help maintain air flow and cooling surfaces and will allow the unit to operate at maximum efficiency. The intentional and/or repeated triggering of the duty cycle protection feature on this unit will shorten the lifespan of the unit’s electronics and can weaken internal components. The effect of overheating your unit repeatedly takes a cumulative toll on the unit. NOTICE: These units are tested by an international and independent certifying agency for their ability to sustain the claims of duty cycle, under lab induced conditions which are typically more stringently controlled than average shop conditions.

WARNING!
Before turning the machine on for the first time, make sure the voltage selector switch on the rear is set to the correct voltage or permanent damage may occur. Correct voltage selection and wiring is the customer’s responsibility. Damage occurring from incorrect wiring or wrong voltage selection is
NOTICE:
The unit is designed with several features and functions in common between processes. The principles of setup and operation carry over from one process to another. In this case, information may not be repeated in detail in this manual if it has been discussed previously in another process.
BREAKER SIZING AND WIRING REQUIREMENTS
Before installation of this unit in any facility, always consult a licensed local electrician familiar with the requirements of properly wiring a welder into the electrical supply. Refer to the National Electric Code (NEC) and local codes. If needed, refer the electrician to Article 630 of the NEC during consultation to determine proper application and wiring needs. Use the I1MAX and the I1EFF ratings listed above to determine the proper breaker and conductor (wire) sizing required. Everlast welders are designed around use in industrial wiring applications and are intended to be used with modern electrical systems. Household wiring may need to be upgraded before this welder may be installed. Additional HF protection and isolation may be needed if this welder interferes with the operation of electrical/electronic equipment. This unit should be operated only on a dedicated branch circuit. IMPORTANT: Do not modify this unit’s wiring, power plug or conductors. This unit meets the standards for conductor sizing on the power cable and takes into account power cable length, duty cycle and rated current.
NOTICE: POSSIBLE HF INTERFERANCE FROM THE INVERTER AND WHAT TO DO IF IT OCCURS
If any electrical disturbance is noticed as a result of the high frequency interference that is possible with the operation of the inverter switching and operation, the HF service bolt should be connected directly to a 12 gauge wire that is bonded directly to an outside copper ground rod driven into moist soil. Additionally, all metal items including any metal frame or sheeting of the building should be connected and grounded to separate copper ground rods driven into the ground at 10 foot intervals around the perimeter of the building. This includes items such as tables, carts, rack material, metal surrounds, etc. that may act as “antenna” to radiate/absorb HF energy. Additionally, all cords and welding leads should be twisted together and run directly to the work without coils or excess cabling. Normally, this will not be required, but it is supplied in the case of any interference that may be observed. This is usually observed in older or non standard installations where grounding and ground isolation is a problem. Normally this is not needed, but if interference is observed, first try relocating the welder and affected objects, and re-route welding cables. If operation is not improved, contact an electrician to wire the ground and make proper ground connections to all metal objects.

Duty Cycle
Duty Cycle is simply the amount of time out of a 10 minute period in which the unit can operate. For example, this unit has a duty cycle of 60% at maximum output, that means that the unit can be operated for 60 minutes out of 10 minutes. This is rated for continuous or intermittent use during the 10 minute period of time. This rating standard (United States) is based on a maximum
ambient temperature of 40 C. Operating
above this point, or at lower temperatures with high humidity may reduce the duty cycle rating. Of course, the duty cycle will increase somewhat as ambient temperature and output Amps drops as well. Regardless, the duty cycle is not controlled by a timer. Rather, a heat sensor located on a heat sink near the critical power components of the welder signals overheat. If the operating temperature of the unit is exceeded, welding output will stop and an overtemperature warning light/error code will be displayed on the screen. If a duty cycle event occurs, do not turn the unit off! Allow the welder to continue to run at idle for at least 10-15 minutes until the temperature has fallen enough to reset the sensor and over-temperature warning light. Even if the unit resets, allow the unit to cool for a full 15 minutes, or the duty cycle will be more quickly triggered since the unit resets just below the heat threshold. The fan(s) should be allowed to continue to cool for a full 15 minutes without welding/cutting activity after a duty cycle shut down has occurred. After 15 minutes of cooling, you may switch the unit off if you are finished welding. If the unit does not automatically reset after 15 minutes, turn the unit off. Wait for 15 seconds before turning the machine back on. If the unit does not reset, contact technical support for further advice and assistance. As a best practice, before shut down, if you have been welding continuously for extended periods of time, keep your unit on for 10 additional minutes to allow it to cool down. The intentional and/or repeated triggering of the duty cycle protection feature on this unit will shorten the lifespan of the unit’s electronics and can weaken internal components. Overheating your unit repeatedly takes a cumulative toll

NOTICE:
The maximum output of the machine is reduced to when operating on 240V 1phase input power. For full power, use 480V 3 phase input power. See above specifications for more information.

Getting Started

UNPACK YOUR UNIT. Upon arrival, you will need to completely unpack your unit, and check things over. This is a time sensitive matter. Do not delay or hold the welder unopened in the box. Make sure the unit is opened from the top. Be careful with using knives and sharp objects so you won’t cut cords and cables inside the boxes. Lay all items out and inspect them. The complete welder package arrives in separate boxes. Make sure no boxes or parts are missing. You should have the following in your box: 1. DC MIG/DC TIG/DC Stick Power Source (bare unit). 2. Wire Feeder (FCS 203) with gas/power umbilical (15ft). 3. PowerCart 400. 4. Floating Ball Regulator for MIG. (hose included but not pictured). 5. 36 Series MIG Gun/Torch. (MB36KD style). 6. 250A Work Clamp (approx. 9.5 ft with cable). 7. 250A Stick Electrode Holder (approx. 9.5 ft with cable). 8.

INSPECT AND ASSEMBLE YOUR UNIT. When you receive your package, inspect the unit for damage. Check for the presence and general condition of the accessories. Some slight rubbing or chaffing of some of the accessories may be present, but this is considered normal. Most notably, the MIG torch may appear to be used or fired. This is because it has been live tested in the factory for proper operation before putting into the box. If any item is damaged or missing, please inform Everlast within 72 hours of product receipt. See pages 4 and 5 for more details.
First, assemble the cart with the main axle, casters, fasteners, washers and cotter pins provided in the package. Use the separate cart manua lfor assembly guidance. You will need to carefully lay the cart on its side for assembly. Use a soft cloth or foam pad under the cart to prevent scratching during assembly. The thumb screws in the cart package secure the welder to the cart from the bottom of the cart. The wire feeder is secured via the swivel post on the top grab bar of the cart.
IMPORTANT! Do not overtighten the screws. If desired for proper fitment or for space saving, the unit may be used without the handle.

However, install the screws and tighten them to the panel anyway. Do not leave them out. After 8 hours of use, check and retighten back plate assembly, casters and axle assembly. Check and inspect the cart periodically to ensure the undercarriage is tight and secure to the welder and the wire feeder. A good time to check is during routine cleaning of the unit.
NOTICE:
This unit includes an additional MIG contact tip, but does not contain any other MIG consumables, including filler (MIG or Flux-Cored) wire. Additional sizes of contact tips, nozzles and basic gun parts are available direct from Everlast’s website, from other online sources and from select local welding supply stores that carry parts for similar MB36KD styled MIG guns. Some miscellaneous parts like a contact tip wrench may be found in the box, depending upon your region. Filler (MIG and Flux-Cored) wire should be purchased locally or direct from other online sources. Other drive roll sizes and types should be purchased direct from Everlast. The included drive roll is a V groove drive roll, designed for solid steel wire. Depending upon the region/country where purchased, drive rolls for flux core or aluminum use, must be purchased separately. Flux-Cored wire will have a serrated or zippered appearance in the groove. The Flux-Cored Drive rolls are indicated by an X or K letter after the size. Aluminum drive rolls will have a Ugroove shape. Make sure you are ordering 4 roll kits designed to fit the FCS 203 feeder. They differ from other 4 roll kits used in selfcontained wire feeder units where the feeder is located in the housing of the welder itself.
If you are considering using .030″ or .035″ wire, you should purchase the 24 series gun in addition to the supplied 36 series. You will need to order a blue liner to go with the 24 gun as well. This will feed wire better and arc performance will be much improved and will provide good performance up to 240A for short circuit or light spray arc use.
The 36 gun, as supplied, is designed primarily for heavy weldments that require spray arc welding. A different combination of consumables will be required to improve short arc performance with the 36 gun.
NOTE: If you think you are missing a needed part, check the consumable kit bag and related packaging before calling Everlast for replacement. If you are missing parts, call 1-877-755-9353 ext. 206 for help.
POWER UP AND TEST YOUR UNIT. You will need to fully assemble (install cart and wire feeder) and test the unit as soon as possible. Within 72 hours after receipt of the unit, be sure to have every thing you need at hand to test the unit. Make sure the correct input power, wiring, and plug configuration is being used for your input voltage. Make sure you have the regulator is installed (See following section). Then, power up your machine without any accessories installed. Allow the unit to idle for 15 minutes. Check and observe operation of knobs, controls and buttons, cycling through each as required. Make sure the fan is running at full speed. After the static run-

ning test is completed, turn the unit off, connect the torches and cables. Then, conduct live testing of all the functions and features of the machine. For testing make sure work clamp is connected directly to the part being welded (work). Check for arc starting and stability. If any welding problems are observed and persist, contact Everlast. However, before you contact Everlast double check that polarity is correct for the process being used. Improper polarity will result in poor welding performance, and in some cases, can result in no arc at all. See page 5 for more contact information. NOTICE: Cosmetic damage claims after 30 days will not be accepted, unless Everlast is contacted and informed of such delay and reason for such a required delay (i.e. Overseas, or while on deployment with the armed services etc.). GIVE YOUR UNIT SOME SPACE TO COOL. This unit needs room to cool itself and maintain proper duty cycle. Place the unit in a place that will allow 18″ from all sides to allow for proper cooling. This welder pulls air in from the rear, and pushes it through the unit’s heat sinks to cool the electronics. The air is then exhausted through the front panel and side louvers of the unit. If any of sides is blocked or restricted, the duty cycle will be reduced, and overheating will occur, leading to possible damage if the restriction is severe enough. Never attempt to restrict air flow by attaching filters to the vents or by modifying your fans for “on demand” service. If the sound from the welder fans diminish or become non existent, check fans for proper operation. If, over time, you suspect one or more of the fans are not working, discontinue use until the unit can be repaired to prevent damage to the machine. One fan not working will cause duty cycle to drop drastically. If your duty cycle warning appears unexpectedly, and continues to do so, contact Everlast tech support for help on checking fan operation and diagnosing the cause.

configuration can vary, consult with a licensed electrician before making any attempt to wire or connect your unit. The unit should be used on a dedicated circuit and should not share operation of another device on the same breaker.

Standard Wire Configuration 3 Phase 480V

CONNECT YOUR UNIT TO POWER. WARNING: Before connecting your unit to power, be sure to select the appropriate power input via the switch on the rear of the welder.

This unit is designed only to operate on either 1 phase 240V or 3 phase 480V. It can be operated on a 3 phase 240V system, however, if you only use two of the balanced power legs and do not use the high (wild leg) of power. Single phase use will cause a higher Amp draw however. Your unit has been shipped without a power plug. This is because it is both single 240V and three phase 480V capable. For 240V 1 phase use, we suggest that you select the NEMA 6-50P. This is the standard plug used for 240V 1 Phase welders in North America. The red wire will not be used. It should be taped up and stored out of the way. It is also important to understand that welders do not require or need a neutral by code. However, the welder does always need to be properly grounded via the green wire. Black and white wires in a 1 phase 240V welder circuit are always used as the “Hot” wires, which measure 120V to ground and 240V phase to phase. Always consult a licensed electrician before making any electrical connection on this unit. Never modify or attempt to rewire this unit in any way. If you are using on 480V 3 phase, all wires will be used, including the red wire. Use the red wire for the “High leg” input. Since there is no standard for 480V 3 phase welder plugs and design, amp rating and

IMPORTANT!
Select input voltage via the switch located on the lower rear
of the welder before connecting the power or damage may
occur to the unit.
Selecting A Breaker and Wire Size
Select a breaker based off of the I1MAX rating of this unit. This is the maximum inrush current of the unit. The inrush is not a sustained current. The I1EFF rating of the unit is the maximum “rated” current of the machine. When combined with the length of the run from the main panel, this determines the conductor size. Refer your licensed, local electrician to Article 630 of the NEC and the specification page of this manual (or the specification grid printed on your unit) to select the correct breaker and wire size. A delayed trip breaker, or slow blow fuse should be used with this unit.

CONNECT YOUR UNIT TO THE CORRECT SHIELDING GAS
What Shielding Gas Should Be Used?
The following gases should be used and are the best choices in the gas selection during initial setup after powering the unit up: MIG Steel Short Circuit: 75%/25% Ar/CO2 (75/25 or C25) OR 100% CO2 (C100) MIG Steel Axial Spray: 90%/10% Ar/CO2 (90/10 or C10) or similar less than 20% CO2 with balance being Argon. MIG Stainless (Inox): Short Circuit OR Spray 98%/2% Ar/CO2 (98/2 ) MIG Stainless Short Circuit Only: He/Ar/CO2 ((Stainless TriMix)
MIG: Aluminum or Brazing: 100% Ar ( Argon) All TIG: 100% Ar (Argon)
Notice that Steel has a couple of gas choices. In the North American Market, 75/25 is the standard gas choice for short circuit MIG and Gas Shieled Flux- cored welding. It provides less spatter than CO2 and a cleaner, less oxidized weld in general. 100% CO2 is cheaper, but can require more cleanup and descaling after the weld is completed. In other markets, 100% CO2 is more commonly available, or may offer slightly different combinations. If 75/25 gas mix is not available for use and 80/20 is an option, then this gas may be used on the 75/25 setting. Any gas less than or equal to 20% CO2 is generally considered suitable for Axial Spray welding.
Stainless gas mixes can range throughout the industry. However, in the industry. this unit is designed to be used with 98/2 Ar/CO2 blend when welding Stainless Steel. While there are other gas choices, such as “TriMix” with He, Ar and CO2, this is typically the most widely available and economic one for welding Stainless Steel (Inox).
MIG Aluminum and MIG Brazing will always require the use of pure Argon (100% Ar) shielding gas while welding in MIG mode. This is a widely available and a standard gas throughout the world.

580 CGA valve). If you do not have a cylinder wrench, an adjustable type wrench will work, but make sure it is properly adjusted to prevent rounding of the fitting shoulders. Do not use pliers, or a serrated -jawed wrench such as a pipe wrench to tighten the fitting. The design of the fitting means that no thread sealing tape or compound needs to be used.
Connect the supplied tubing to the regulator. Tighten with two 3/4″ (19mm) wrenches to hold both the regulator and the tubing connection at the same time. Hold counter pressure on the regulator connector while tightening the hose fitting to prevent damage to the regulator. After connecting the tubing to the regulator, connect the other end of the tubing to the 5/8″ CGA fitting on the welder. Hold the fitting on the unit with one 3/4″ (19mm) wrench firmly while tightening the hose fitting with another 3/4″(19mm) wrench. NOTE: Some regulators use an 11/16″ (17mm) fitting.
Important: Do not use thread tape or pipe sealant on any cylinder, regulator or unit connection. The residue and debris may get into the gas solenoid and cause operational issues.
CAUTION! Do not tighten the rear unit connection without holding the female 5/8 CGA fitting located on the back of the welder with a wrench, or damage may occur to the solenoid, housing or fitting as the fitting may turn in the housing while the hose fitting is being tightened.
Connect Regulator To Cylinder And Unit.

TIG uses Argon for all metals. Never accept any other gas for DC TIG welding.
WARNING! Always wear safety glasses and gloves when changing a gas cylinder. Always use safety chains to secure the cylinder to the welder.

Carefully lift and install the gas cylinder onto the welder back deck plate while safety cap is still on. Use the supplied safety chain to secure the cylinder to the cart as tightly as possible. Once the cylinder is installed, it may be uncapped when ready for use. Before connecting any cylinder, stand to the side of the cylinder valve, making sure you are away from the discharge side opening. Then, quickly open and shut the cylinder valve giving it a quick blast. This will dislodge any dirt or particles stuck in the valve or the connection seat. This will help reduce the chance of dirt particles making its way into the solenoid valve, causing sticking issues later on in service.
Connecting your cylinder will require a cylinder wrench (1 1/16″)to connect the regulator to the cylinder (North American Cylinders with a

SELECT THE CORRECT TORCH SETUP AND POLARITY.

POLARITY FOR SOLID WIRE MIG / GAS SHIELDED FLUX-CORED WIRE

The polarity of the welder is controlled on the main unit via the DINSE type connectors. These connectors that can be used are the DINSE 35/50mm2 or the DINSE 35/70mm2 style connectors. The both have the same diameter connecting pin, but the cable size that the connector is capable of accepting are different.
To change the welder’s polarity, simply swap the cables on the main power source. This includes the wire feeder cable when switching from MIG to Gasless Flux-Cored wire.
NOTICE: For MIG and wire feed applications the wire feeder will connect directly to the power source via an umbilical cable (provided) and the gun will connect to the wire feeder. The work clamp will connect directly to the power source. The wire feeder is designed to be mounted directly to the PowerCart 400. However it may be used independently from the cart if precautions are taken to secure the feeder from overturn and moving. For all other applications the torch cables and the work clamp will connect directly to the power source.
See the general torch polarity recommendations below. These are the normal configurations for each process. But with wire feed operations and with stick, polarities may vary from what is listed. Confirm the recommended torch polarity with the maker of the filler metals (consult packaging paper work or box of filler metals or manufacturer’s website for more information) as occasionally there are exceptions based off of application.
GMAW (MIG, INCLUDING SPOOL GUN/ALUMINUM): Connect wire feeder to Positive (+), Work Clamp is connected to Negative (-). The Spool gun uses the same configuration when being used for welding Aluminum, Stainless and other solid wire metals.
FCAW (Self Shielded Flux-cored): Connect wire feeder to Negative (-), Work Clamp is connected to Posititve (+). For gasless, self shielded flux cored wire use, purchase a flux-cored gun. Do not attempt to use the standard gun unless operating briefly. Performance with the stock gun will be limited Everlast does not offer a flux-cored gun. This must be purchased aftermarket. The use of aftermarket guns does not affect warranty.

Hint: Always make sure that you re-trim the wire before beginning a new weld if the wire is not already trimmed to this length. This will help to improve arc restarts.
PROPERLY TENSION THE WIRE FEEDER.
To feed properly, the wire needs to be tensioned before you begin welding. The tensioning levers have numbers on the dial. To increase tension, rotate the tension lever clock-wise. Different types of wires require different tensions. There is no exact tension that works for all wire types. However, for steel wire, you will generally tension to around 3 on the dial. Wire diameter can affect the tension requirement slightly. Wire quality also plays a small part in the amount of required tension that is needed. Lower quality wire may have slight variations in thickness, causing slippage of the drive rolls at various points, while no slipping is observed at others. For flux-cored wire, it will require a lighter amount of tension. For Aluminum, try 1.0 to 2.0 on the dial. Regardless of the wire type or wire diameters (and for best results), follow the process below and refer to the following illustration. Turn the unit on and pull the trigger so that the wire extends approximately 1″ beyond the gas nozzle.
· Find a small block of wood, such as a two by four, and secure it to the welding table or other solid object. Do not test this on metal or arcing may occur if the work clamp is connected!
· Hold the gun approximately 2 inches off the wood. Aim the gun at the block of wood so that the nozzle is at a 30 degree angle to the wood.
· Pull the trigger and allow the wire to contact the block.
· Increase wire tension so that the wire contacts the block of wood and is forced to curl up. Continue holding the trigger so that two or three full spirals are made.
· If the wire stops, or stutters during this process, let go of the trigger immediately and increase tension.
· Adjust the wire until the stuttering or jerking disappears.
· Do not over-tighten the tensioner or use more tension than necessary. When the wire begins to curl without any stoppage, the tension is enough.

SELECT THE PROPER TUNGSTEN TYPE.
TUNGSTEN SELECTION
Selecting the correct tungsten for your TIG welder is important. While Thoriated 2% Tungsten can be used in an inverter for DC welding, it is falling out of favor in the industry due to the slight radioactive nature of it. But as of now it is still an industry standard in North America. It should be noted that it has already been banned in some countries. Check your country or regions policy on Thoriated Tungsten. Other types are quickly becoming available everywhere. Call your local welding supplier or check online for sources.
For TIG welding with DC consider the following types.
· Lanthanated 2% (Blue Band). Overall this is one of the best choices for TIG welding and can be used for AC and DC welding. It has great arc starting characteristics, and its point holding capability is excellent.
· Ceriated 2% (Gray Band or Orange Band, depending upon brand and country of origin). This is a good choice for welding with both AC and DC, but doesn’t hold up as well and starts to erode faster than Lanthanated at higher amperages. But arc starting is excellent.
· Lanthanated 1.5% (Gold Band). Holds up nearly as well as Lanthanated 2% and can be used for AC or DC welding. In some tests it has rivaled Lanthanated 2% performance.
· Tri-Mix/Rare Earth (Purple Band or Turquois Band). Still relatively new. Some swear by it, and is being marketed as a replacement for Thoriated 2%. Overall, it does perform fairly well and even excels in many circumstances. But some problems have been seen with quality control. The primary metal oxide used is lanthanum 1.5%. Usually it also includes a small percent of Zirconium and Cerium to complete the mix. Some use Yttrium. But the balance of the composition blend are usually stated to be around .06 to .08%, but can be allowed to vary up or down from .04% to .01%, making he blend prone to inconsistency in quality control.
· Thoriated 2% (Red Band) Still considered the best for DC, works ok for AC, but has been banned in many markets outside the US due to a small radiation risk posed as an alpha emitter.
Do not use the following types of Tungsten.
· Pure Tungsten (Green Band). This will create arc instability. The tungsten will not stand up well to the more intense arc created by an inverter welder.
· Zirconiated Tungsten (White Band). This was created as an alternative for Pure Tungsten for Transformer welders. Similar issues welding issues are presented as with Pure Tungsten.

Purchasing Tungsten can be difficult. Local suppliers tend to put a premium price on Tungsten, and may be three times an online price direct from a distributor. In many areas, the choice of tungsten may be limited. However, many local welding suppliers are stepping up and offering competitive prices and range of selection, so don’t rule them out until you have checked. Also, there are some companies that may send you free samples to test, so be sure to investigate their product, and give them a chance as well.
GRIND THE TUNGSTEN CORRECTLY. An improperly ground tungsten is a cause of many issues with arc stability, arc directability, and penetration. A bench grinder and a fine stone dedicated only for tungsten sharpening is all you need to put a point on the Tungsten. This is the age old standard. This does take practice to master. However, there are hand held special grinders that feature diamond stones with guided slots, designed to hold the tungsten at the proper angles. A chemical sharpener is available and is relatively inexpensive, and does an excellent job in seconds. An added bonus of it is that it can be done without getting up from the bench top without removing the tungsten from the cup. The tungsten should be hot before attempting as this activates the chemical.
! WARNING!
Wear safety glasses and leather gloves while grinding tungsten or serious injury may occur. On occasion tungsten may split or shatter. Do not breathe or inhale tungsten dust. Do not use angle grinders!
How Do I Grind My Tungsten?
· Grip the Tungsten firmly. Grind with the tungsten secured. · Grind the Tungsten perpendicular to the wheel face. Allow tung-
sten to grind slowly without much pressure. · Rotate the Tungsten quickly as it is being ground to keep the
point even and symmetrical. · Do not grind the Tungsten parallel to wheel face or an unstable
arc will result.
22

Component Identification and Explanation

Getting Started

Choosing the proper grind angle is important to achieving the weld penetration, bead appearance, and arc cone width that you desire. While there is no true “one size fits all” angle, there are some general rules of thumb to observe:
· Always grind in-line with the length of the tungsten. Never make radial grind (in the direction of the circumference) marks on the tungsten which will cause arc instability. Never grind with the tungsten held parallel to the stone face.
· For most applications, grind a point that is 2 ­2.5 times in length than the tungsten is wide. This will create an angle of about 30 to 35 .
· For AC, a more blunt angle may be used (around a 60 degree) for best penetration. However, the 2 to 3 times in length rule will still work for many circumstances.
· For higher amperages, you will want to put a slightly truncated tip on the tungsten.
· Grip the tungsten firmly and slowly rotate it while grinding.
GRINDING TUNGSTEN CORRECTLY
· Never use a radial grind pattern. This can be caused by grinding at the wrong angle, or spinning the tungsten too fast while grinding at the proper angle. The arc will be unstable.

As you use the tungsten (depending upon the type you have selected) you will notice that the tungsten will gently form more of a pointed dome as it is used. This is normal and the arc will remain stable. Depending upon what arc properties you are looking for, you may periodically want to regrind your tungsten to maintain optimal arc characteristics.
The use of a scratch start TIG rig tends to accelerate wear on Tungsten. Experienced users, however, are able to get many starts out of the Tungsten before a regrind is necessary. Inexperienced users may find themselves regrinding nearly after every start!
If the start is performed incorrectly, small bits of Tungsten will be left to contaminate the weld puddle. For best results, especially for beginners, leave a slightly blunt point on the end of the Tungsten so the end of the Tungsten will not snap off into the weld while striking an arc. The best key is to practice and follow the arc starting directions found in the “Explanation of MIG and TIG Operation” section.

· Grind the angle so that the length of the grind measures 2 to 2.5 times the wide of the tungsten (For general purpose use this should form about a 30 to 35 angle.) A slightly blunted end (truncated) may be used if the amperage is over 50A to prevent the tungsten from breaking off into the metal while welding.
<50 A
2.5 ­ 3 X Ø (DIAMETER)

· AC welding may require a blunter point for some applications where greater penetration is desired. It may seem counterintuitive, but this will create a narrower arc cone and provide more penetration.

TIG mode, keep in mind the Tungsten is continuously live. An accidental contact with any weldable, connected surface will result in an accidental arc flash. The arc start type of this welder is sometimes called lift start, but more properly it is actually scratch start. This means that the Tungsten must be struck against the surface of the weld metal to start the arc. It can

to 315 A. For TIG, Stick and Arc Gouging, it is reduced from 400A to 300A. For full 400A output the unit should be used on 480V 3 phase. However, whether operating on 240V 1 phase or 480V 3 phase the duty cycle remains unchanged at the maximum respective outputs at 60%.

NOTICE:
Over time, pressure on the drive rolls causes metal fragments from the filler wire’s surface to find its way to the gun cable liner. If the wire guide is not cleaned, it can gradually clog up and causes wire feed malfunctions. Other factors control smooth wire feeding as well. Wires that are .023″ to .035″ (.6mm to . 9mm) require a liner change from stock size of the gun and/or smaller gun to prevent wire balling/bird’s nesting at the feeder. For wires .030-.035″ and smaller, consider purchasing the 24 series gun along with a blue liner. The .030″ wire diameter should not be used in a gun over 12.5 feet (4m). Purchase of an optional liner and possibly a smaller series gun such as the 15 or 24 series, which are available from Everlast, is recommended for use with these smaller sizes for best performance. This unit is not recommended for use with .023″ wire unless a 10 ft 15 series gun is connected. NOTICE: If feeding difficulty is observed, first confirm that the liner is the proper size and torch is proper length for your wire diameter, then: 1. Remove the welding gun’s gas nozzle, contact tip and contact tip’s adapter. 2. With an air nozzle blow compressed air through the wire guide. Wear eye protection! 3. Blow out the wire feed mechanism and reel housing with dry compressed air. 4. Reassemble components. Tighten the contact tip and contact tip’s adapter with the spanner included to ensure tightness.
Do not overtighten any fittings or stripping of the threads may result. The MIG torch liner may eventually become worn and will need to be replaced. When welding aluminum with the main gun, a polymer liner must be used, which necessitates a liner change. A spool gun is the preferred method to weld Aluminum, but a polymer liner may be used with guns10ft. and under to weld aluminum. In this case, you will need to change the standard liner intended for steel use to feed directly from the machine and use U groove drive rolls to prevent deformation to the wire. To change the liner: 1. Remove the nozzle and the securing compression nut of the liner (#17) to expose the brass fitting end of the liner (if a
polymer liner is already installed it will be a brass ferule and o-ring) . 2. Straighten the gun cable and withdraw the liner slowly from the gun. If the liner refuses to be withdrawn easily, this could
indicate severe liner damage or gun cable damage. 3. Carefully push a new wire guide in to the gun. Make sure that the wire guide travels all the way to the contact tip without
interference with tip. Remove Contact tip once installed. 4. For Polymer liners, make sure the O-ring and brass ferule at the machine-end of the gun are installed. For steel liners
make sure the fitting is flush and the O-ring is in place. 5. Tighten the liner in place without over tightening, especially with the polymer liner. 6. For polymer liners cut the line 1 to 2 mm from the rear compression nut (at the Euro quick connect fitting) and file the
sharp edge of the liner. For steel liners, no trimming is required unless liner is sticking out gun handle too far. If the liner is passing the point where the contact tip screws in and seats, remove and trim the liner with a pair of side cutters or similar tool and file any sharp edges before reinserting the liner. 7. Reattach the gun and tighten all parts. 8. Re-thread wire through the feeder and gun, leaving contact tip off until wire feeds completely through the gun. Once the wire feeds through install contact tip and nozzle.

To prevent the wire from sticking in the weld after feeding after the arc is terminated during wire feed welding,

burn back provides voltage for a short duration after the wire stops feeding. This is often caused by the fresh-

Burn Back Intensity

prevalent when using wire too small for the liner. Burn back should be adjusted for intensity of effect. Different wire diameters, weld positions, and even welding styles may require different amounts of burn back. For burn-

back to work properly, the MIG gun must be held over the end of the weld for a brief second. If continuity is

lost the wire may not burn back properly. Burn back also helps reduce the need for trimming the wire before

the next weld. Sometimes this is referred to as a “wire trimming effect.” This is a 0-10 scale adjusted for effect.

2T and 4T are used only for wire feeding applications. This allows the user to select how the torch trigger

the arc and released to stop. 4T is more complicated, but still relatively straight forward. When 4T is used the

Process Selection

in mind while arc gouging arc voltage is typically very high. Long arcs and use at the maximum settings may trigger an overcurrent or duty cycle event more quickly than realized since this is a near 100% duty cycle

activity. The unit is designed to withstand carbon arc gouging, but some basic restraint should be observed

when setting the maximum amps when 100% duty cycle arc gouging activity is expected.

gas such as 90/10 Ar/Co2. The stock torch can be equipped with a smaller liner and different consumables, but it is often easier to weld with a smaller

.045″: 1 x Amps = Inches per Minute (IPM)

gun when smaller wire diameters ( .035″) are used. This allows greater

flexibility and accuracy of the gun.

To convert wire speed (IPM) into approximate Amps, use the following conversion formula:
.023″: IPM ÷ 3.5 = Amps
.025″: IPM ÷ 3.1 = Amps
.030″: IPM ÷ 2 = Amps
.035″: IPM ÷ 1.6 = Amps
.045″: IPM ÷ 1 = Amps
Keep in mind these are approximate conversions and do fall off in accuracy as amps are increased into the upper current limits for the given wire diameter. Also keep in mind that this machine displays settings in percent of maximum wire feed speed so some conversion to approximate Amp settings may be required.

The wire can also pop and spatter if the voltage is too low for the wire speed and/or wire diameter. This is mostly observed as flying bits of redhot but un- melted wire, along with popping as the wire inconsistently stubs into the puddle. This is followed by the wire pushing back against your hand pressure while the wire visibly turns white/red hot before burning off. Too low of voltage will also produce a high piled bead with the toes (edges) of the weld not properly wetting in resulting in poor fusion. Similarly too much voltage can cause spatter and undercut.
In fact, different diameter wires have a maximum “stability” range in which they physically perform best. With either too high of voltage or wire feed speed the capability of the wire may be easily exceeded. Once the maximum current carrying limits of a particular wire diameter has been reached, it can cause the wire to weld uncontrollably, burn back to the tip or even gas off alloys of steel with lower melting points directly and generally cause poor feeding performance which results in a poor weld.

Even though you will find general recommendations about setting the

The wire diameter also limits the practical maximum thickness of

Starting the arc is a relatively simple process. Before beginning, the wire should initially be trimmed to between 1/4 to 3/8″. Once the wire is trimmed, the gun should be firmly grasped to prevent a phenomenon often referred to as “machine gunning”.

In reality, both are correct if used correctly and with each having particular strength and weakness. Either one done with too much gun angle will result in undesirable results. Most learning minded people who are well versed in MIG quickly develop a sense of when to push and when to pull the gun. Even for novices, a sense of when to push and pull the gun comes quickly with a little practice. Pushing can result in shallower penetration but the molten puddle is easier to see and the arc sits easily on the leading edge. It will usually leave a aesthetically pleasing bead. However, be careful to prevent the gun from leaning toward or away from the direc-

MIG and TIG welding requires a well prepped surface to obtain a sound weld. The removal of paint, rust mill scale, or other contaminate such as grease should be done before welding. Stick welding is more forgiving of rust and mill scale, but when MIG welding, contaminates will result in porosity and inclusions in the weld, weakening it. In TIG welding it can be disastrous. TIG requires the most cleaning effort. A grinder will usually prep the metal sufficiently to remove oxidation and paint. However, to remove grease a degreaser such as acetone should be used. Do not use any degreaser such a brake cleaner with chlorinated solvents or death or serious injury may occur!

become turbulent, creating porosity in the weld. Pulling will result in deeper penetration, but can result in a narrow bead without much side fusion. It also can leave an undesirable humped appearance if not done correctly or if travel is too slow. Whenever MIG welding with Aluminum, whether with the standard MIG gun or the Spool gun ALWAYS push the gun. If using Flux Cored wire, a dragging motion is almost always recommended.

MIG and TIG filler wires such as ER70S-6 or ER70S-2 include a sufficient level of deoxidizers such as silicone and copper that are formulated to allow it to handle minor to moderate amounts of rust and mill scale. These deoxidizers will float out most moderate amounts of contaminates out of the weld and will appear in the usual form of glassy like deposits on top of the cooled metal. They are easily brushed off before starting the next pass. They should not be welded over. Any pinholes that appear are a

Starting and ending an arc with a DC TIG Rig.
This unit is equipped with a traditional DC Scratch Start TIG Rig. This means torch connects directly to the regulator and the gas flow is controlled manually with a gas valve on the torch. There is no automatic solenoid control. Nor is there a HF start or even a true lift start.
To Start, the gas valve is opened on the torch neck so that Argon begins to flow freely. Then, once the gas has had time to cover the weld area, the arc is scratch started with a quick flicking motion of the Tungsten against the metal. (This is traditionally steel or stainless welding.) This scratching/ flicking motion creates an small, sparking arc and the tungsten is quickly raised to establish a firm arc. With practice this can be a smooth seamless start to the naked eye. Experienced users will often ground their filler wire to the metal and flick against the filler metal itself to start the arc. This provides a cleaner start and reduces tungsten wear when mastered.

DIFFERENT COMMON TYPES OF WELD JOINTS
Besides a butt joint (Flat edge to flat edge) and lap joint (overlapping edges) which are often used for thinner metal gauges, consider using one of these groove joints for best welding results. When grinding or cutting the bevels, especially with a single V-groove, it may be beneficial to leave a small land with a gap between the joint to achieve full penetration. In this case a temporary backer plate can be used to support the bottom of the weld to create the root pass. The root weld will weld the backer to the main plate. This backer can later be ground or cut off. However, in many cases a plain open root can be used as a backer plate adds to the time and labor involved. A knife edge is also acceptable so long as the joint is fully penetrated when the weld is completed. Open root gaps without a backer can range from 1/16″ to 1/8″ depending upon wire diameter and application.

USE MULTI-PASS WELDS
When welding material 1/4″ and over be careful about trying to put too much metal down in a single pass. Use multiple passes to complete the weld along with any necessary joint preparation especially with wires of smaller diameter. As metal thickness goes up so does the number of required passes. Depending upon the wire diameter and power settings used, a 1/4″ joint may only require 1 or 2 passes, but a 3/8″ joint in plate metal or pipe will require not only beveling but 4 to 6 overlapping weld passes including a cap and root pass. See Example below.

PUSHING VS. DRAGGING TECHNIQUES IN MIG
MIG Welding is fairly simple if you keep travel angle and direction in mind when welding. See below. If you are welding fluxcore, the gun direction is reversed. Remember: If it has gas, you use a push angle. If it is gas-less you use a drag angle. The old welder’s saying “If it has slag, you drag.” applies to Flux-Cored Wire welding.

VERTICAL

NO YES

Problem Technique: The Gun is not being held vertical from side to side. Wire is not being directed to the center of the puddle. This concentrates heat on one side of the joint and results in poor fusion on the neglected side. It also can create more buildup on one side of the joint than the other. Correction: Hold the gun so that the angle of the neck stands perpendicular from side to side.
Correct Technique: The gun is held in a near vertical position. A variance of 5 degrees or less is acceptable from side to side. The purpose is to prevent the arc from being concentrated on one side of the weld joint or the other. This balances the heat on both sides of the joint and keeps the bead centered. Don’t confuse this with push or pull angle in the travel direction.

OK

Correct Technique: The gun is angled toward the back of the weld when traveling forward. This angle should not exceed 15 degrees. This provides a narrower but more deeply penetrating weld. Use this method when Flux Core wire is being used. Use this method where the unit may be reaching its maximum welding capacity. Not for use with Aluminum wire.

PULL 15°

YES Correct Technique: The gun can be angled toward the front of the weld when traveling forward. This angle should not exceed 15 degrees. This provides a wider and generally more pleasing weld. However it is shallower penetrating. This method typically allows a much better view of the arc. Use for most types of welding unless deeper penetration must be achieved.

Stick Welding Information
STICK ARC STARTING METHODS 1. Make sure the unit is turned on and the boot cycle has finished.
2. Select the Stick Process on the Selector.
3. Make sure the electrode holder is in the Positive connector and the work clamp is in the negative connector.
4. Select the Amp level desired. No voltage adjustment is available. Select Hot Start Time and Hot Start Amps % (Intensity) to improve starting reliability. Use higher amounts of Hot Start %, over 50% with difficult to strike rods, or rods that aren’t fresh or out of a sealed metal can.
5. Use the arc force control to select the desired arc characteristics, creating the desired arc characteristic and amp response needed to maintain the arc. Cellulose electrodes may not have the same arc force behavior as other welding electrodes, but each brand and size will weld a little differently. Typically rods such as the E6011 will require a setting 60-80% for best results. The arc force control setting will vary from person to person as well, with different rod angles, positions, and arc lengths all factoring into the arc force control performance. If you are new to using an inverter welder, there are some aspects that will seem different. One of the main ones is that the arc is better controlled in most situations by “pushing in” when the arc seems to get weak or unstable and the arc force will kick in as the voltage drops. If the arc length is too long, the voltage rise will signal the inverter to shut down and will terminate welding output. This is done to limit amp draw on the circuit. This threshold is shorter than most transformers, and an extremely long arc cannot be maintained. However, with a little practice, the arc will be easy to manage with some adaptation in technique.
6. Strike the arc with either the tapping method or the match strike method. Beginners usually find that the match strike method typically yields the best results.

Tapping

Scratch/Match

HELPFUL HINT:
Pay particular attention to the Arc Force setting as it affects the aggressiveness of the arc and the amp response. Set the Arc force to approximately 34 and readjust it from that point to find the optimum setting. Adjust in half increments up or down from there to obtain the best results Usually, an increase in the arc force for cellulose based flux welding rods is helpful. Lowering the Arc force setting is generally desirable for rods iron powder/ Titania based flux. Too much arc force will create overheating of the welding rod, and even cause them to flame up. Too little can lead to sticking and arc snuffing. When welding, the weld will be slower than MIG speed. One of the most common mistakes for users transitioning from MIG to Stick welding is the travel speed. Allow the metal to fill the puddle as the rod travels forward. Be sure to try to separate the difference between the slag and the molten pool of metal. The slag will coalesce behind the puddle if travel and rod angle is correct. Do not let the slag travel in front of the puddle. Keep the top of the rod inclined to the direction of travel around 10-20 degrees while welding in the flat position (Electrode holder should be in front and inline of the puddle). To begin, simply start the arc, and then drag the rod slowly and carefully along the metal, allowing the rod flux to provide a standoff between the metal filler and the puddle. Be sure to keep feeding the rod steadily downward into the puddle as the rod melts. In the case of E6010, 6011, and other rods with a cellulose based flux, a slight stepping motion in front of the puddle about 1/8″-1/4″ in front of the puddle can be used as a key hole opens up in the weld joint, ahead of the puddle. This is also called “whipping” the rod. Do not flip the end of the rod away from the puddle in a arc motion or the arc may terminate while using E6010 or similar cellulosic rods. When experience is gained, numerous manipulation methods may be used with rods such as E7018, 7014, 6013, and 7024. Weave the rod no more than 2.5 times the width of the welding rod. To begin weaving, weave small, tight patterns similar to C’s, cursive E’s, V’s, or even figure 8’s.
