A breakthrough control that automatically sets your welder to the proper parameters.Auto-Set offers all-in-one MIG minus the guesswork! Simply set the wire diameter, set the material thickness and start welding!

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.

Thermal Overload Protection
Shuts down the unit and activates over-temperature light if airflow is blocked or duty cycle is exceeded. Automatically resets when fault is corrected and unit cools.

Standard Built-In Solid-State Contactor Circuit
Makes wire electrically "cold" until trigger is pulled. This makes the unit safer and torch easier to position before starting to weld.

This technology provides a smooth, spatter-free start. The best starting machine in the small MIG category! No more pop-gun starts or spatter to clean up.

Durable Cast Aluminum Drive System
Incorporates dual groove quick-change drive roll and spring-loaded tension arm with calibrated tension knob, all designed to make setup easier and faster.

Tip Saver' Short Circuit Protection
Shuts down output when tip is shorted to the work. Extends contact tip life and protects internal components from damage. Trigger reset permits quick reset at torch rather than unit.
