WARNING!
Read and understand all safety warnings and instructions carefully before using this machine. Failure to follow the warnings and instructions may result in electric shock, fire, and/or serious injury. Save this manual for future reference.
Only qualified persons should install, operate, maintain, and repair this unit.

WELDING SAFETY TIPS:

Exposure to a welding arc is extremely harmful to the eyes and skin. Prolonged exposure to a welding arc can cause blindness and burns. Never strike an arc or begin welding unless you are adequately protected. Wear fire-resistant welding gloves, a heavy long-sleeved shirt, cuffless pants, high topped shoes, and a welding helmet.
CAUTION:
To prevent serious injury, fire, and burns:
Keep welding tips clear of grounded objects whenever the unit is plugged in.

WELDING PREPARATION:

An important factor in making a satisfactory weld is preparation. This includes studying the process and equipment and practicing welding before attempting to weld the finished product. An organized, safe, ergonomic, comfortable, and a well- lit work area should be prepared for the operator. The work area should specifically be free of all flammables with both a fire extinguisher and a bucket of sand available.
To properly prepare for welding with your new welder, it is necessary to:

• Read the safety precautions at the front of this manual.
• Prepare an organized, well-lit work area.
• Provide protection for the eyes and skin of the operator and bystanders.
• Attach the ground clamp to the bare metal to be welded, making sure of good contact.
• Make sure that the wire-roller groove in the roller corresponds to the diameter and type of wire being used.
• Plug the machine into a suitable outlet.

FIRE PRECAUTIONS

• All flammable materials MUST be removed from the welding area.
• DO NOT strike an Arc on or near the gas cylinder.
• DO NOT attempt to weld fuel or gas containers unless adequate procedures have been taken to ensure that no vapor remains. Fuel tanks should be thoroughly steam cleaned before welding.

WELDING FUMES

Toxic gases are given off during the MIG welding process. Always use in a well- ventilated area.

ARC GLARE

Always use a face shield or welding helmet fitted with the correct glass filter. Never use damaged safety equipment.

HEAT

Wear welding gloves at all times whilst welding. They will protect the hands from ultra-violet radiation and direct heat of the arc. It is also recommended that overalls are worn.

ADDITIONAL PROTECTIVE CLOTHING

• When welding at higher settings wear a leather apron to protect the operator from spatter
• When welding in the overhead position, a suitable cap should protect the head and neck.
• We recommend that you wear industrial footwear including steel toes caps.

IMPORTANT:

1. These units should never be exposed to rain or snow.
2. Do not use in a wet or damp environment.
3. Never use to thaw or heat up frozen pipes.
4. These units should be connected to the main supply through a circuit breaker.

PARTS DESCRIPTION

NOTICE:
While installing the new solder wire. Please take off the protective sheath and contact tip of the MIG torch (see picture 1). Then press the Mig torch switch to let the wire out till 3.5cm. At last, assemble the protective sheath and contact tip back (see pictures 2 and 3). To avoid the wire block the contact tip.

SETTING UP THE WELD:

1. Make practice welds on pieces of scrap the same thickness as your intended workpiece to practice the technique before welding anything of value.
2. Clean the weld surfaces thoroughly with a wire brush or angle grinder; there must be no rust, paint, oil, or other materials on the weld surfaces, only bare metal.
3. Use clamps (not included) to hold the workpieces in position so that you can concentrate on proper welding techniques. The distance (if any) between the two workpieces must be controlled properly to allow the weld to hold both sides securely while allowing the weld to penetrate fully into the joint. The edges of thicker workpieces may need to be chamfered (or beveled) to allow proper weld penetration.
4. Clamp Ground Cable to bare metal on the workpiece near the weld area, or to the metal workbench where the workpiece is clamped.
5. Set the Wire Speed Dial and the Current Switch to the desired settings. Refer to the chart on the Welder or the chart on the facing page. WARNING: Do not switch the current while welding.
6. Flip the Power Switch to the OFF position, then plug the Welder into a dedicated, 120 VAC, 20 A circuit with delayed action type circuit breaker or fuses.
7. Hold the Gun, without touching the Trigger, with the wire and tip clearly away from any grounded objects. Then, turn the Power Switch to ON.

FEEDING THE WIRE

When fitting a new reel adopt the following procedure.
a. Remove the shroud from the torch and unscrew the contact tip.
b. Fit the wire reel onto the spindle. The spring mounting must be correctly fitted.
c. Locate the free end of the wire usually positioned in a thole on the reel rim. Remove the end of the wire from the hole and use sharp wire cutters to remove any distorted wire. Do not allow the wire to become slack on the reel.
d. Hinge back the pressure arm and feed the end of the wire into the hole at the end of the liner. Ensure that the wire is fitted so that it is fed into the wire feed mechanism in a straight line.
e. Fasten the pressure arm down ensuring that the MIG wire is in the groove in the feed roller. Ensure that the correct groove is used depending on the diameter of the wire i.e. one groove is for 0.6mm and the other for 0.8mm.
f. To reverse the roller, unscrew the two screws securing the roller, supporting bracket, and remove the bracket. The roller can then be removed from its shaft and reversed.
g. Hold the torch straight. Switch the machine on and operate the torch trigger, the wire feed roller will tum feeding the wire through the torch.
h. The wire will emerge from the far end of the torch, then feed the tip onto the wire (make sure the tip is the correct size for the diameter of the wire being used), tighten it and replace the shroud.

BASIC WELDING TECHNIQUE

1. Press (and hold) Trigger and contact area to be welded with electrode wire to ignite arc.
2. For a narrow weld, you can usually draw the wire in a steady straight line. This is called a stringer bead. For a wider weld, draw the wire back and forth across the joint. This is called a weave bead.
3. Hold Gun in one hand and the face shield in the other. If a hands-free welding shield is used, then both hands can be used to control guns.
4. Direct the welding wire straight into the joint. This gives an angle of 90° (straight up and down) for butt (end to end) welds and an angle of 45° for fillet (T-shaped) welds.
5. The end of the Gun should be tilted so that the wire is angled anywhere in between straight on and 15° in the direction you are welding. The amount of tilt is called the drag angle.
6. The welding wire should extend no more than 1/2″ past the tip. This distance is called stick out or CTWD.
7. After welding the test weld on a piece of scrap for a few seconds, stop, and check your progress.
8. When the weld is complete, lift the Gun and welding wire clearly away from any grounded object, and turn the Power Switch off.
9. Set the Gun down on a heat-proof, electrically non-conductive surface. Unplug the Power Cord.

GETTING TO KNOW YOUR FLUX-CORED WIRE WELDER

1. HANDLE
   The rugged, top-mounted handle allows for easy transport of your welder and a place to wrap your cables.

2. INPUT VOLTAGE INDICATOR LED
   This will be illuminated when the input voltage to the machine is present and the ON/OFF SWITCH is in the ON position.

3. FAULT/THERMAL OVERLOAD INDICATOR LED
   This will be illuminated under the following conditions:
   a. The duty cycle of the machine has been exceeded or airflow is blocked. The fan will continue to run until the machine has cooled, but output power will be disabled. Ensure that the cooling fan is running and that there are 12 inches of clearance around all vents. When the LED turns off, welding power will be enabled again.
   b. If the LED Indicator Light remains illuminated for more than 10 minutes, it is likely that there is an input voltage problem.

4. VOLTAGE ADJUSTMENT KNOB
   Use this dial to adjust the arc voltage or “heat” of your welder (1 is the lowest and 10 is the highest). Different materials and material thickness will require different voltage settings. You will need to adjust your voltage accordingly for different welding conditions. By properly adjusting your voltage settings and wire feed speed, you will produce clean welds.

5. WIRE FEED ADJUSTMENT KNOB
   Use this dial to adjust the speed at which the welder feeds wire to the gun (1 is the slowest and 10 is the highest). You will need to adjust or “tune in” your wire speed for different welding conditions (thickness of metals, metal type, wire size, etc.) Refer to the setup chart for a starting point. When the wire speed is properly “tuned-in” the welding wire will melt into the material you’re welding as quickly as it is fed through the welding gun. This welder operates best between 5-7 on this dial and will do well in most conditions in this range.
   NOTE: This is a scale, not actual wire feed speed.

6. MIG GUN AND CABLE
   The welding gun controls the delivery of the welding wire to the material to be welded. The welding wire is fed through the welding cable and welding gun when the welding gun trigger is pulled. You will need to install a contact tip and welding nozzle to the end of the welding gun prior to welding.

7. GROUND CLAMP AND CABLE
   Attaching the ground clamp to your workpiece completes the welding current circuit. You must attach the ground clamp to the metal you are welding. If the ground clamp is not connected to the metal workpiece you intend to weld, the welder will not have a completed circuit and you will be unable to weld. A poor connection at the ground clamp will create an erratic arc and may damage your welder. Scrape away dirt, rust, scale, oil, or paint before attaching the ground clamp.

8. ON/OFF SWITCH
   This switch turns the welder ON and OFF. (Make sure the power switch is in the OFF position before performing any maintenance on the welder.)

9. INPUT POWER CABLE
   This is a standard, grounded 120-volt power cord. (Make sure you are using a properly grounded 120 Volt AC, single-phase power source with 20 amp time- delay (“slow-blow”) breakers.)

10. WIRE SPOOL SPINDLE

11. TWO-ROLL WIRE FEEDER

SELECTING THE WELDING WIRE

This welder uses only four or eight-inch spools of 0.030-inch (0.8mm) self- shielding flux-core wire. Steel from 24 gauge up to 1/4-inch thick can be welded with 0.030 -inch wire. Larger diameter wire will be less capable with thicker materials, will not increase your deposition rate, and may overdraw your AC power source.

NOTE:

• If a spool has developed heavy oxidation, the only solution to the problem is to discard the spool of wire.
• If you have an oxidized spool of wire, do not discard it until you have unspooled a few turns of wire to see if the wire farther down on the spool is in usable condition. If it is not, discard the spool.

TROUBLESHOOTING

•  Torch moved over the workpiece too slowly.
Weld deposit incomplete and stringy| •  Torch moved over the workpiece too quickly. Rust, paint, or grease on the workpiece.
Arc unstable, excessive spatter, and weld porosity| •  Torch held too far from the workpiece.
•  No gas – check bottle content, connections, and regulator settings.
•  Incorrect gas for the material.

Wire repeatedly burns back

| •  Torch held too close to the workpiece.
•  Break in the welding circuit Possible causes:
•  Incorrect size of contact tip for wire.
•  Contact. tip damaged – replace.
•  Contact tip lose – tighten.
•  Feed rollers are worn – replace.
•  Welding wire corroded – replace.
•  Pressure roller adjustment incorrect – adjust.
•  Pressure roller sticking – lubricate or replace.
•  Wire tangled on reel
__

Lack of weld penetration

| •  Welding output too low.
•  Wire feed speed too low.
•  Torch moved too fast.
Burning holes in a workpiece| •  Welding output too high.
•  Torch moved erratically 0r too slowly.
No arc produced| •  Earth lead or torch cable in open circuit.
•  Poor earth clamp connection
Welder does not operate (mains indicator not lit)| •  Check mains connection.
•  Check supply fuse.
Welder does not operate with trigger pressed| •  Check torch trigger and its connections.
•  Thermal overload cut out – allow to cool.

ROUTINE MAINTENANCE

Electrical repairs must only be carried out by a qualified or approved engineer.
Welding Cables: Regularly inspect their connections.
Torch: Regularly dean the contact tip and shroud to remove spatter that will eventually disturb the flow. Spraying the tip and shroud with an anti- spatter spray can reduce the build-up of the spatter. Replace the tip periodically to maintain good electrical contact between the tip and the wire. Blow clean dry air through the torch liner from time to time to ensure the wire passes freely through it If this has no effect the liner should be replaced.
Note: Ensure the torch lead is held in a straight line and fully extended when feeding the wire through the torch, otherwise, there is a risk of the wire puncturing the wire feed liner and torch hose.
