DUTY CYCLE
The rated Duty cycle refers to the amount of welding that can be done within an amount of time. The azznuo MIG-200F has a duty cycle of 60% at 200 Amps for 110/220 Volts. It is easiest to look at your welding time in blocks of 1 O Minutes and the Duty Cycle being a percentage of that 1 O Minutes. If welding at 200 Amps with a 60% Duty Cycle, within a 10-minute block of time you can weld for 6 Minutes with 4 Minutes of cooling for the Welder. If the Duty Cycle is exceeded, the Welder will automatically shut off, however, the fan will continue running to cool the components. When a safe temperature has been reached, the Welder will automatically switch the Welder output back on. To increase the duty cycle you can turn down the Voltage Output control.

WARNING
THE BUILDUP OF GAS CAN INJURE OR KILL!

Shut off the shielding gas supply when not in use.
Always ventilate confined spaces or use an approved air-supplied respirator.
Always turn your face away from the valve outlet when opening the cylinder valve.

WARNING

CYLINDERS CAN EXPLODE IF DAMAGED!
Shielding gas cylinders contain gas under high pressure. If damaged, a cylinder can explode. As gas cylinders are a normal component of the welding process, use extra care to handle them carefully.

Protect compressed gas cylinders from excessive heat, mechanical shocks, physical damage, slag, open flames, sparks, and arcs. Keep away from any welding or other electrical circuits.
Install cylinders in an upright position by securing them to a specifically designed rack, cart, or stationary support to prevent falling or tipping over.
Never weld on a pressurized cylinder or an explosion will occur.
Use only correct shielding gas cylinders, regulators, hoses, and fittings designed for the specific application; maintain them and all related components in good condition.
Keep a protective cap in place over the valve except when the cylinder is in use.
Use proper equipment, and procedures and have adequate help when moving or lifting cylinders.

A Shielding Gas Bottle is NOT INCLUDED with your azznuo MIG-200F but is necessary to weld using Solid Wire. It can be bought at most local Welding Supply Stores. azznuo recommends the use of 80% Argon / 20% CO2 or 75% Argon / 25% CO2 for shielding gas when MIG welding Steel.

Place the azznuo MIG-200F in its dedicated area or on a welding cart.
Secure your Shielding Gas Bottle to a stationary object or mount it to your welding cart if it is equipped to hold one so that the cylinder cannot fall over.
Remove the cap from the Shielding Gas Bottle.
Install the Regulator Knob on the Shielding Gas Regulator (FIG 8).
Insert the large brass male fitting on the Shielding
Gas Regulator into the female fitting on the Shielding Gas Bottle (FIG 9).

NOTICE
Do not use White Thread Sealing Tape on this connection as it is an inert gas fitting and does not require it. If you leak, check for burrs or dirt in the threads.

Tighten the fitting with a wrench until snug, do not over-tighten.
Connect either end of the Gas Line included with your azznuo MIG-200F to the fitting on the regulator and wrench tighten until snug (FIG 9).
Connect the other end of the gas line to the fitting on the rear of the azznuo MIG-200F and wrench tighten until snug (FIG 1 O).
Check the gas line for leaks by slowly opening the valve on the gas bottle. When welding the valve on the bottle should always be fully open.

POSITIONING THE DRIVE ROLLER
The azznuo MIG-200F Wire Drive Roller has twin grooves to accommodate both .030″/.035″ [0.8mm/0.9mm] wire. The MIG-200F Drive Roller is factory set and up ready to use .030″/.035″ [0.8mm/0.9mm] wire. IMPORTANT NOTE: In this position, the wider, .030″/.035″ [0.8mm/0.9mm] grove is inboard, under the wire while the 0.8/0.9 marking is visible on the outward face of the Drive Roller (FIG 11 ). . 030″ [0.8mm] or .035″ [0.9mm] wire can be used with the Drive Roller in this position.

Open the side door of the Welder to access the drive motor compartment (FIG 12).
Push the Pressure Adjuster rearward, pivot it down and out of the way then pivot the Tension Arm up away from the Drive Roller (FIG 13).
Loosen and remove the Drive Roller Retaining Knob (FIG 11 ).
Remove the Drive Roller and view the wire sizes stamped on each side of the Roller.
Install the Drive Roller in the orientation so that the chosen wire size stamping is facing outward making sure the shaft key aligns with the Drive Roller keyway. (FIG 11 ).
Reinstall the Drive Roller Retaining Knob on the shaft.
Replace the Tension Arm and re-latch the Pressure Adjuster.

INSTALLING THE WIRE SPOOL
The Azznuo MIG-200F can be used with either a 4″ or an 8″ wire spool.

SETTING THE WIRE PRESSURE ADJUSTER
To set the tension on the wire, incrementally tighten the Spool Retaining Wingnut until there is a slight resistance to spinning the wire spool on the spindle. If the tension is set too loose the wire spool will freely spin on the shaft and unspool all the wire. If the tension is too tight, the Drive Roller will have difficulty pulling the wire off the spool and some slipping may occur.

THREADING WELDING WIRE THROUGH THE DRIVE MOTOR TO THE WELDING GUN

WARNING
ELECTRIC SHOCK CAN CAUSE INJURY OR DEATH! Disconnect the Welder from the power supply before beginning.

This Welder uses wire sizes ranging from .030″ to .035″ (0.8mm to 0.9mm). To safely and correctly install the welding wire, follow the procedure in the sequence outlined below:

Verify that the facility power source has properly rated wiring to handle the power requirements of this Welder.

Your azznuo MIG-200F can be used to form many different joints and welds all of which will require practice and testing before using on an actual project piece. This following welding process is just a baseline to get you started.

Connect your ground clamp to the workpieces that are to be welded. Make sure the ground clamp contacts are placed on a clean piece of metal free of paint, grease, rust, oils, etc. It is recommended to place your ground clamp as close to the weld area as possible.
Assess your weld area and make sure the welding area is also cleaned of any paint, grease, rust, oils, etc.
Plug in the Welder and move the Power Switch at the Upper Back Panel to the “ON” position Depress the Welding Gun trigger pointing the welding gun away from your body and then let go of the trigger and cut the wire back to 1/4″ stick out length.
Wearing your welding helmet, gloves, and long sleeve shirt and pants, put the end of the wire sticking out of the gun into the joint to be welded.
Position the MIG Gun so that it is perpendicular to the base metal with a -20° tilt back.
Depress the trigger to start the wire feed which starts the arc.
NOTE: A push, perpendicular, or drag technique can be used to weld the pieces together; the type used depends on the type of joint as well as other influential conditions.
Once you depress the trigger and the arc has started, you will notice a molten puddle will form; this puddle is the weld bead and will follow the motion of the MIG Gun. Watching the size of the puddle dictates how fast you should be moving with the torch. If you burn through the material you are either moving too slowly or you need to make some setting adjustments to the Welder settings. If you’re not penetrating the base metal you’re either moving too fast or you need to make adjustments to the Welder settings.
Release the trigger on the MIG Gun to stop the weld.
After welding is complete, turn off the Welder and disconnect from the power source.

SHEET METAL WELDING TECHNIQUES
When welding sheet metal a different approach is usually taken to account for how thin the metal is and its susceptibility to warping it is. The technique most often used is called Stitch Welding and this process is described below:

Clean the metal to be welded of any paint, rust, oil, grease, dirt, or any other contaminants that may be on the surface of the piece.
Secure the pieces to be welded in place using clamps. Be sure to leave a small gap between the two pieces of sheet metal for the weld to flow into, this will result in a lower bead height which will require minimal finishing.
Consult the Suggested Settings Chart and set the Voltage and Wire Speed knobs appropriately. Get some pieces of scrap metal of the same thickness and verify that the settings will work for the specific weld you will be making.
Once the settings have been fine-tuned tack weld your final pieces in places and remove the clamps if they are in the way of the weld.
The Stitch Welding technique can now be utilized which is a series of tacks connecting. To perform the technique, trigger the gun to form a tack weld and then continue to trigger on and off the gun making a series of connected tack welds following along the path of the weld joint. Continue the series of tacks for an inch or so and then move to a different section of the weld and perform the process there. It is essential to keep moving around to spread out the heat making sure not to get one section too hot and warp the metal.
Once the entire weld has been completed allow the metal to cool. If necessary follow up with a flap disc to grind the weld bead flush.

HEAVY GAUGE METAL WELDING TECHNIQUES
When welding heavy gauge metal, a continuous bead is formed using a ‘push’ method. This process is described below:

Clean the metal to be welded of any paint, rust, oil, grease, dirt or any other contaminants that may be on the surface of the piece.
Secure the pieces to be welded in place using clamps. Be sure to leave a small gap between the two pieces of metal for the weld to flow into, this will result in a lower bead height which will require minimal finishing. Any material thicker than 1/8″ should be beveled using an angle grinder.
Consult the Suggested Settings Chart and set the Voltage and Wire Speed knobs appropriately.
Get some pieces of scrap metal of the same thickness and verify that the settings will work for the specific weld you will be making.
Once the settings have been fine-tuned tack weld your final pieces in places and remove the clamps if they are in the way of the weld.
When welding heavy gauge metal there are two basic approaches to creating the weld. The first is a continuous bead with steady gun movement along the length of the joint. The second type of weld is a Stringer or Weave bead. This is accomplished by moving the torch in a circular or zig-zag pattern. Either of these techniques will create strong welds but in some cases, the Stringer or Weave type will create a more aesthetically pleasing weld bead.
Once the entire weld has been completed, allow the metal to cool. If necessary, follow up with a flap disc to grind the weld bead flush.

STICK WELDING OPERATION

Electrode Selection
Before beginning welding with your azznuo MIG-200F, you will need to purchase electrodes as these are consumable items in the ARC welding process. There are a variety of different types of rods available and should be selected depending on the project on hand. The chart below is an overview of some of the most popular electrodes. azzuno-200A-MIG-Welder-fig-
32

POLARITY SELECTION

The azznuo MIG-200F can weld in both Direct Current Electrode Positive (DCEP) and Direct Current Electrode Negative (OGEN). The electrode, or rod, when welding in DCEP is positive and the grounded surface is negative. This polarity is used with electrodes that specify it and is usually the most commonly used polarity when ARC welding for general-purpose use. The electrode when welding in OGEN is negative and the grounded surface is positive. This polarity is used with electrodes that require using this polarity and is usually used for building up heavy deposits of material with less penetration.

To use the azznuo MIG-200F in DCEP:

Locate the Ground Clamp with Cable and connect the plug on the cable end to the Ground Cable Connector (-) on the Welder. To connect the plug line up the key on the plug with the keyway on the socket of the Welder, insert the plug, and twist until it is tight.
Locate the Electrode Holder with Cable and connect the plug on the cable end to the Electrode Holder Connector (+) on the Welder. To connect the plug line up the key on the plug with the keyway of the socket on the Welder, insert the plug, and twist until it is tight.

STICK WELDING PROCEDURE

Set up a clean well-lit work area.
Prepare the parts to be welded by cleaning the weld joint area of any rust, dirt, grease, or paint.
Select the proper electrode for the weld joint.
Turn on the Welder and select the appropriate amperage. To determine proper amperage it is best to practice on some similar metals to set up the machine before welding on an actual part of value.
Attach the ground clamp to a clean bare metal section on the work piece.
Insert the electrode into the electrode holder being careful not to allow the electrode to contact the grounded area.
To start welding an arc must be struck, to do this a motion similar to striking a match will have to be performed with the electrode. Slowly bring the electrode closer to the weld joint and then contact and drag the electrode across the piece to strike the arc. Once the arc has been stuck you can continue feeding the electrode into the weld joint.
While moving along the weld joint the electrode will burn down, while it is burning you will need to continue moving the electrode closer to the joint trying to keep a 1/8″ gap between the end of the electrode and the weld joint. The electrode holder must be held so that the electrode is at a downward angle moving in the direction of the weld joint.
To stop welding simply lift the electrode away from the workpiece. When finished welding remove the electrode from the holder and turn off the Welder.

Lift TIG WELDING SET-UP AND OPERATION

SHIELDING GAS CONNECTION FOR Lift TIG TORCH

WARNING BUILDUP OF GAS CAN INJURE OR KILL!

Shut off the shielding gas supply when not in use.
Always ventilate confined spaces or use an approved air-supplied respirator.
Always turn your face away from the valve outlet when opening the cylinder valve.

WARNING CYLINDERS CAN EXPLODE IF DAMAGED!

Shielding gas cylinders contain gas under high pressure. If damaged, a cylinder can explode. As gas cylinders are a normal component of the welding process, use extra care to handle them carefully.
Protect compressed gas cylinders from excessive heat, mechanical shocks, physical damage, slag, open flames, sparks, and arcs. Keep away from any welding or other electrical circuits.
Install cylinders in an upright position by securing them to a specifically designed rack, cart, or stationary support to prevent falling or tipping over.
Never weld on a pressurized cylinder or an explosion will occur.
Use only correct shielding gas cylinders, regulators, hoses, and fittings designed for the specific application; maintain them and all related components in good condition.
Keep a protective cap in place over the valve except when the cylinder is in use.
Use proper equipment, and procedures and have adequate help when moving or lifting cylinders.

A Shielding Gas Bottle is NOT INCLUDED with your azznuo MIG-200F Lift TIG Torch Kit but is necessary for Lift TIG welding. A Shielding Gas Bottle can be bought at most local Welding Supply Stores. azznuo recommends the use of 100% Argon shielding gas when Lift TIG welding Steel and Stainless Steel.

After connecting your Shielding Gas Regulator, the gas flow rate needs to be adjusted so that the proper amount of Shielding Gas is flowing over your weld. If there is too little gas flow there will be porosity in your welds as well as excessive spatter, if there is too much gas flow you will be wasting gas which may affect the weld quality.

Place the azznuo MIG-200F in its dedicated area or on a welding cart.
Secure your Shielding Gas Bottle to a stationary object or mount it to your welding cart if it is equipped to hold one so that the cylinder cannot fall over.
Remove the cap from the Shielding Gas Bottle.
Install the Regulator Knob on the Shielding Gas Regulator (FIG 8).
Insert the large brass male fitting on the Shielding Gas Regulator into the female fitting on the Shielding Gas Bottle (FIG 9).

NOTICE

Do not use White Thread Sealing Tape on this connection as it is an inert gas fitting and does not require it. If you have a leak check for burrs or dirt in the threads.
• Tighten the fitting with a wrench until snug, do not over-tighten.
• Connect the Lift TIG Torch gas line to the fitting on the Regulator and wrench-tighten until snug (FIG 9).
• Check the gas line for leaks by slowly opening the valve on the gas bottle. When welding, the valve on the bottle should always be fully open.

TORCH ASSEMBLY/DISASSEMBLY

Disassembly:

• Make sure the welder is turned OFF and unplugged.
• Remove the Back Cap from the Torch.
• If there is a Tungsten installed in the Torch pull it out of the front of the Torch.
• Slide the Collet out of the Torch.
• Unscrew and remove the Gas Shielding Nozzle.
• Unscrew and remove the Collet body.

Assembly: (Fig 16)

Select a Collet body that matches your Tungsten diameter size and thread it into the front of the Torch.
Select a Collet that matches your Tungsten diame to size. Insert the Tungsten into the Collet and put the Collet and Tungsten back into the Torch.
The Gas Shielding Nozzle size should be changed according to shielding gas requirements for the material being welded. Thicker material requires a larger Nozzle. Select the correct Gas Shielding Nozzle and thread it onto the Collet body.
Install the back cap to lock the Tungsten in place. Always make sure the Tungsten protrudes 1/8″ to 1/4″ beyond the Gas Shielding Nozzle (FIG 17).

SHARPENING THE TUNGSTEN
To avoid contamination of the Tungsten and ultimately the weld, it is imperative to have a dedicated grinding wheel used for Tungsten grinding only. A fine-grit standard 6″ synthetic stone grinding wheel on a bench top grinder is sufficient or our specifically designed azznuo Tungsten Grinders are available.

Shut off the welder.
Make sure the Tungsten and Torch are sufficiently cooled for handling then loosen and remove the
Back Cap then the Collet and remove the Tungsten from the FRONT of the Torch only. (Re moving from the rear will damage the Collet).
If the Tungsten is used and the end is contaminated, use pliers or a suitable tool to grip the Tungsten above the contaminated section and snap off the end of the Tungsten.
Holding the Tungsten tangent to the surface of the grinding wheel, rotate the Tungsten while exerting light pressure until a suitable point is formed. The ideal tip will have the length of the conical portion of the sharpened area at 2-1/2 times the Tungsten rod diameter (FIG 18).
Replace the Tungsten in the Collet with the tip extending 1/8″-1/4″ beyond the Gas Shielding Nozzle, then re-tighten the Back Cap (FIG 19).

IMPORTANT NOTE:
These instructions are intended only to provide the user with some familiarity with the azznuo MIG-200F. Lift TIG welding is a highly complex procedure with many variables. If you have no experience with Lift TIG welding; it is extremely important to seek the advice of someone experienced in Lift TIG welding for instruction, enroll in a local technical school welding course, or study a comprehensive how-to DVD and obtain a good quality reference book on TIG welding as there is a moderate learning curve necessary before achieving proficiency in TIG Welding. Before attempting to use this unit on an actual project or object of value, practice on a similar material as there are many variables present and settings required when TIG welding different metals such as steel and stainless steel. It is also strongly recommended that the user adhere to the American Welding Society guidelines, codes, and applications before producing welds where safety is affected.

Turn the Power Switch at the Upper Back Panel to the “ON” position.
Slowly open the gas cylinder valve.
NOTE: Always open the valve fully to avoid shielding gas leakage.
Adjust the flow regulator built-in to the Torch Handle. Rotate Counter-clockwise to open, Clockwise to Close.
Grounding is very important, place the Ground Cable Clamp on a clean, bare area of your workpiece as close to the welding area as possible to minimize the chance of shock. Scrape, wire brush, file or grind a bare area to achieve a good ground to assure safety.
Use a dedicated stainless steel brush or flap disc to clean the areas to be welded. Do not use the brush or flap disc for any other purpose.
Make sure all your safety gear is in place (Welding Mask, Welding Gloves, non-flammable long-sleeve apparel) and the area is completely free of flammable material.
Although it is a matter of developing a personal style, a good starting point for best results is achieved by holding the tip at a 45° angle backward and approx. 20° to the right of the weld. Hold the Filler Metal Rod at a 60° angle to the Tungsten Tip. Never allow the Tungsten Tip to touch the welding surface or material rod. Doing so will quickly destroy the tip and contaminate the weld. If this happens, remove the Tungsten and regrind the tip. It is best to hold the Tungsten tip 1/8″ from the surface.
With your Welding Shield and all safety gear in place, practice “Forming a Puddle” with the Tungsten Tip. Once you become familiar with this step. Practice the “Dip and Pull” technique with the Filler Metal Rod and Torch. “Dip and Pull” is the practice of forming a puddle, moving the Torch while maintaining the puddle, and adding filler rod metal to the puddle by “dipping and pulling” as you go; being careful not to allow the Tungsten to contact the puddle or rod.
To stop welding, pull the Tip back over the weld approx. 1/2″ [13mm] then lift to break the arc. Keep shielding gas flow in place for approx. 1 O seconds.
Keep in mind that you MUST let the shielding gas flow over the weld for approx. 10 seconds. Failure to do so will allow the welded area to oxidize as it cools, compromising the weld integrity.
Constantly be aware that TIG welding quickly generates heat in the workpiece and Torch. Severe burns can quickly occur by contacting hot metal pieces.
When done, shut off the Power Switch, close the Regulator in the Torch Handle then close the Shielding Gas Tank valve completely.

OVERLOAD PROTECTION

Your azznuo MIG-200F Welder is equipped with an overload breaker. This device will protect your Welder if the duty cycle is exceeded. If the output is exceeded, the internal breaker will trip and stop the power supply to the drive motor although the fan will still run to cool the unit. If the breaker tripped resulting from an overload, the Overload Indicator will illuminate E 2. Allow the Welder to cool for a minimum of 15 minutes before attempting to resume welding.
