Setup

Gun Cable: The welding Gun connects here. The wire and welding current feeds to the weld through here.

The welding Gun is energized whenever the Power Switch is on.

Wire Speed Dial: This controls the speed that the welding wire feeds out of the welding Gun.

Adjust this according to the weld settings chart to achieve a good weld.

Ground Cable: This connects to the base metal to provide a good connection for the current to travel back to the welder.

Power Cord: Plug the Power Cord into a properly grounded 120 V~ outlet, on at least a 20 amp dedicated circuit with delayed action type circuit breaker or fuses.

Current Switch: This controls the output amperage of the welder.

Adjust this according to the weld settings chart to achieve a good weld.

Power Switch: This turns on power to the welding Gun and internal cooling fan. The welding Gun is energized whenever the Power Switch is on.

Overload Indicator: This lights up if duty cycle work period is exceeded, overheating the welder. Rest the Gun on an electrically non-conductive, heat- resistant surface, such as a concrete slab, well clear of the ground clamp while allowing the welder to cool with the Power Switch on, so the Fan can help cool the welder. Once the welder cools enough to be used again, use shorter welding periods and longer rest periods to prevent needless wear.
