Welds 24 gauge - 3/16 in. mild steel. Uses 120V power.


Auto-Set™ automatically provides the right settings to weld mild steel while infinite voltage control allows the flexibility to manually set your own parameters.

• Set the wire diameter, a blue light shows Auto-Set is activated

• Dial in the thickness of what you’re welding

• Start welding with the exact parameters you need!


Angled cast-aluminum drive system with calibrated tension knob creates consistent feeding and easy setup for up to 15-foot MIG guns.


Quick Select™ 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.


Smooth-Start™ provides a smooth, spatter-free start. It’s the best-starting machine in the small MIG machine category.


Thermal overload protection shuts down unit and activates the over temperature light if

airflow is blocked or duty cycle is exceeded. Automatically resets when unit cools.


Uses 4- or 8-inch (102 or 203 mm) spools and can be set up to weld with .024–.030 inch (0.6–0.8 mm) solid wire and .030–.035 inch (0.8–0.9 mm) flux-cored wire.
