Welds material from 22 gauge to 1/2 in thick in a single pass. Highest output in its class.


Highest output in its class (250 A at 28 VDC). Weld longer on high-end applications.


Infinite voltage control with self-calibrating digital meters that permit presetting of voltage and wire feed speed. Ensures precise parameters and accuracy.


Integrated digital timers come complete with presettable preflow/postflow, burnback, spot and delay (stitch) timers. Independent timers for MIG and spool gun.


Line voltage compensation keeps power constant even if power input varies by ±10 percent.


Active Arc Stabilizer™ minimizes weld cleanup, and provides excellent starts proven superior to the competition.


Auto Gun Detect™ allows operator to simply pull trigger on MIG gun, spool gun or push/pull gun. Automatically detects and recalls the voltage, wire feed speed and timer of the active gun.


Heavy-duty aluminum, two-drive-roll system.


Fan-On-Demand™ power source cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled though the machine.


EZ-Change™ Low Cylinder Rack Allows operators to easily roll cylinders on and off of rack - no need to lift cylinders.


EZ-Access™ consumable compartment and parameter chart. Set weld parameters right the first time with convenient flip-down compartment that provides fast access to parameter chart and consumables.


Superior aluminum MIG welding with direct connection of optional push-pull guns and spool guns. Now directly connect your XR™ push-pull guns or Spoolmate™ 200 and Spoolmatic® spool guns. No extra module to buy or install.
