Operation
The MIGWELD100 Welder is used to welding sheet metal and light carbon steel.
Caution: Before arc welding read and understands all safety precautions and warnings
listed.
1. Securely clamp the Ground Cable Clamp (33) as close as possible to the metal object to be welded, or
to the metal workbench where the object is mounted and electrically connected.
2. Set the switch on the control panel as appropriate.
3. Verify that the Power Switch is in the OFF position, then plug the MIGWELD100 Welder plug into a
dedicated, 110VAC, 20amp line with delayed action type circuit breaker or fuses.
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 (16).
6. Orient yourself on the area to be welded, and then place the Face Shield over your eyes.
Warning: Never look at the ignited arc without arc shaded, eye protection in a full-face
shield. Permanent eye damage or blindness can occur. Skin burns can occur. Never
breath arc fumes.
7. Press (and hold) the Torch button and stroke the area to 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 angle .The wire
feeds automatically at a speed dependent on the Current setting.
