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.

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.

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.

EZ-Change™ Low Cylinder Rack

Allows users to easily roll cylinders on and off of rack - no need to lift cylinders.

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.

Line Voltage Compensation

Keeps welding output constant even if power input varies by +/- 10%.

Reduce Maintenance and Operating Costs

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

Larger Work Area

Now with longer 15-ft M-25 MIG gun!
