Additional Features

Built-in Pulsed MIG programs
All programmed information is stored for MIG, push-pull and spool guns, and is restored after each power up.

Single- or three-phase input power
With line voltage compensation for constant output even with fluctuations to the input power.

Aluminum Pulse Hot Start
Automatically provides more arc power to eliminate a “cold start” that is inherent with aluminum starts.

Superior aluminum performance
Direct connection for optional XR push-pull guns or Spoolmatic spool gun. With Gun-On-Demand, simply pull the trigger for the gun to be used and you’re ready to weld.

Auto-Gun Detect
Automatically adjusts voltage, wire speed and timers for faster switching between MIG, push-pull and spool guns.

Fan-On-Demand cooling system
Only operates when needed, reducing power consumption and contaminants drawn into the machine.

Industrial four-roll wire drive system
Features two easy-to-set, scaled, tension adjustments and quick-change reversible drive rolls for .035- and .045-inch (0.9 and 1.2 mm) wire.

Internal timers
Adjustable crater feature optimizes crater size for steel, stainless, aluminum and metal-core applications. Crater time delay allows deactivation of crater feature for tack or small welds.
