120V Input Power

120 Volt Power

Uses 120V household input power so there is no special power requirements.  Flexible to use in any location!


Smooth Start Technology

This technology provides a smooth, spatter-free start.  The best starting machine in the 120V MIG category!  No more pop-gun starts or spatter to clean up.

Angled cast
Aluminum drive system with calibrated tension knob creates consistent feeding and easy setup.

Thermal Overload & 'Tip Saver' Short Circuit Protection
Shuts down the unit and activates the over-temperature light if the airflow is blocked or duty cycle is exceeded.  Tip Saver shuts down output when the tip is shorted to the work extending tip life and protecting internal components from damage.

Quick Select™ Drive Roll
Drive Roll
Makes setup quicker by offering three grooves - two for different size solid wire and a third for flux-cored wire.

Auto Spool Gun Detect™
Automatically detects when a MIG gun or spool gun is connected eliminating the need for a switch.

Generator Compatible
