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

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. 


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.
EZ-Change™ Low Cylinder Rack
Allows users to easily roll cylinders on and off of rack - no need to lift cylinders.
Larger Work Area
Now with longer 15-ft M-25 MIG gun!
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%.
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.
