1. Securely clamp the Ground Cable Clamp (33) as close as possible to the metal object
to be welded, or to the metal work bench where the object is mounted and electrically
connected.
2. Set the switch on the control panel to MIN or MAX, as appropriate.
3. Verify that the Power Switch is in the OFF position, then plug the MIG-100 Welder
plug into a dedicated, 110 VAC, 20 amp line with delayed action type circuit breaker or
fuses.
If an extension cord is used, it must have the following wire size: up to 30 feet, use 12
AWG size wire; 30 to 50 feet, use 10 AWG wire; Over 50 feet, use 8 AWG wire.
4. While holding the Torch Cable Clamp with electrode wire clearly out of the way of any
grounded objects, turn the Power Switch to the ON position.
5. Momentarily press the Torch switch to test the wire feed speed.
Adjust the speed by turning the Wire Feed Speed Knob (9).
6. Orient yourself on the area to be welded, then place a face shield over your eyes.
Warning: Never look at the ignited arc without ANSI-approved,
arc-shaded, eye protection in a full face shield. Permanent
eye damage or blindness can occur. Skin burns can occur.
Never breathe welding fumes.
7. Press (and hold) the Torch button and stroke the area to
be welded with the electrode wire to ignite the arc.
Never tap the electrode wire into the welding surface to
ignite the arc. This damages its external coating on the
electrode which prevents oxygen in the air from coming
into contact with the molten metal, causing it to oxidize.
8. Once the arc is ignited, tilt the electrode wire forward at an angle of approximately 35°.
The wire feeds automatically at a speed dependent on the Min. or Max. current setting.
Note: If too much current is drawn from the Welder, the Thermal Overload protector will
activate, the amber indicator will light, and the Welder will turn off until it cools down. If this
happens, turn the Power Switch to the OFF position and wait about 3 ~ 5 minutes.
9. When the weld is complete, lift the electrode wire clearly away from any grounded
object, set the face shield down, turn toward the Welder, and turn the Power Switch to
the OFF position.
10. Unplug the Power Cord from the electrical outlet.
