MIG Welding
1.
Place the MIG welding unit no closer than six feet from the workpiece to be welded.
2.
Connect the MIG torch control. Twist to lock in place. Plug in the grounding cable to the ground
connector on the upper unit front. Twist to lock.
3.
Securely place the clamping end of the grounding cable clamp to a part of the workpiece or metal table
that is clean of paint, oil, or dirt. Clamp it as close as possible to the workpiece without damaging the
cable during welding.
4.
Assemble the wire feeder and keep the wire over 1/2 inches over the torch. Then assemble the torch
well.
5.
Assemble the desired accessories and tips inside the tip of the MIG torch handle. Insert the contact tip
(2b) onto the wire and screw it firmly into the head tube (3b) of the torch handle. Replace the nozzle
(1b) and cut off any excess wire over 1/2 inches.
6.
Connect the hose and gas regulator coupling on the CO2 gas tank (none included) with the CO2 gas
inlet on the back of the unit. Follow the gas cylinder manufacturer's instructions for set-up and use.
7.
Put the metal to be welded on the metal weeding-cutting table. Ensure the metals to be welded are
clean, so good welding efficiency can be promised.
8.
Verify that the Power Switch is in the off position, and then connect the power cord into an appropriate
outlet and turn the welder ON. The Power Light will illuminate, but the Torch is not yet energised.
9.
Point the torch away from all objects and press the trigger until the wire feeds out of the gun two
inches. If necessary, slightly move the torch handle in a circular motion to help feed the wire properly
out of the head tube
Caution: The torch handle is now energised. Be careful not to touch anything else with the horch except
the workpiece to be welded.
10. When everything is prepared well for welding, preset the parameters according to the job needed. Hold
the trigger down and tilt the torch forward. Touch the wire to the workpiece.
Basic Welding Technique
1.
Press (and hold) trigger and touch area to be welded with the 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 Welding Wire back and forth across the joint in a curve. This is called a "weave
bead".
3.
Hold torch in one hand and the face shield in the other.
4.
Direct the welding wire into the joint at right angle. This gives an angle of 90° (straight up and down)
for butt (end to end) welds, and an angle of 45° for filter (T-shaped) welds.
5.
The end of the torch should be tilted so that the wire is angled anywhere between straight on and 15°
in the direction you are welding. The amount of tilt is called the drag angle.
6.
When the weld is complete, remove the gun and welding wire from any grounded objects and turn the
power switch off.
Arc (stick) Welding
1.
Turn the current adjustment knob to meet the needs of the job.
2.
Move the MIG/ARC switch to "ARC"
3.
Connect the electrode clamp and cable to the torch control connector and twist to lock in place.
4.
Plug the cable of the grounding clamp into the DC ground connector and secure the clamp to a clean,
exposed metal part of the workpiece.
5.
Place the metal portion of the welding rod inside the jaws of the Electrode Clamp.
Welding rod types vary for welding different metals.
Note: If the current drawn from the welder is too high, the thermal overload protector will activate, the
overload indicator will light, and the welder will turn off until it cools down. It will automatically reset.
When finished welding
a)
Release the torch handle trigger and lift the torch handle from the workpiece.
b)
Press the power Switch to the off (O) position.
c)
Set the torch handle down on the metal workbench.
d)
Turn the air supply off.
e)
Unplug the line cord from the electrical outlet.
