  • Auto-Set™
    A breakthrough control that automatically sets your welder to the proper parameters. Auto-Set makes set up very simple and gives you precise settings instantly.

    Compatible with Spoolmate 200 Series Spool Gun!
    The Spoolmate 200 saves time for the operator by eliminating the need to go back to the machine to change wirefeed speed.
    Manual Mode
    Gives you the flexibility to manually set the machine when welding aluminum, stainless steel or anytime you want to set your own parameters on mild steel.
    Line Voltage Compensation
    Keeps welding output constant even if power input varies by +/- 10%.
    Standard Built-In Solid-State Contactor Circuit
    Makes wire electrically "cold" until trigger is pulled. This makes unit safer and torch easier to position before starting to weld.
    Reduce Maintenance and Operating Costs
    Our Fan-On-Demand™ cooling system only operates when needed, reducing power consumption and contaminants drawn into the machine.
