Easy-to-use Digital Operator Interface and attached parameter chart makes it simple to set weld parameters.

Convenient built-in gun and cable holder and consumable compartment.

*1 Second Tip Saver - Arc shuts off if tip is shorted to work surface for more than 1 second.
*3 Second Gas Saver - Gas is shut off if arc is not detected 3 seconds after trigger is pressed.
*2 Minute Wire Saver - Wire drive is shut off if arc is not detected 2 minutes after trigger is pressed.

Industrial, dual-gear-driven, aluminum drive system features no-tool, quick-change reversible drive rolls and an easy-to-set, scaled tension knob.

Fan-On-Demand™ cooling system only operates when needed reducing power consumption.
