All-in-one wire welder that welds material from 22 gauge to 3/8 in. thick in a single pass..


Auto-Set™ makes setup quick and easy and works with .030- and .035-inch wire.


Infinite voltage control. When used in manual mode provides broader operating range with finer control than a tap machine.


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


No more replacing mechanical output contactors. Our built-in solid-state contactor circuit makes wire electrically “cold” until trigger is pulled, and gives you life-long welding output and performance.


Gun-On-Demand.™ Simply pull the trigger for either gun and you’re ready to weld. No wasted time installing modules and using gas valve kits.


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.


Compatible with Bobcat™ welder/generators.


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.


Aluminum MIG welding with optional Spoolmate™ 200 spool gun. Wire feed speed control on the gun saves time by reducing trips back to the machine. Also compatible with more industrial Spoolmatic® spool guns.
