Unique Features

With an Advanced Auto-Set feature and a Quick Select Drive Roll, the Miller Electric 120/240VAC welding machine makes MIG welding simple even for the most inexperienced of users.

Advanced Auto-Set

The Advanced Auto-Set feature makes Miller products shine. This feature allows users to dial in the type of wire, type of gas, and thickness of wire in use and let the machine handle the complicated calculations from there.

Multi-Voltage Plug

The included Multi-Voltage Plug offers two adapters for either 120V or 240V. Simply change the adapter, plug in the machine, and go.


With the Fan-On-Demand feature, this machine cuts down on fan use and only operates the fan when it reaches a certain internal temperature.

This prevents the fan from wearing out too soon and reduces noise pollution too.

Quick Select Drive Roll

The Quick Select Drive Roll includes two grooves for solid wires and one for flux core so you can quickly and easily set your wire and start welding.


The Miller Electric 120/240VAC welding machine includes a Smooth-Start function. This makes it easy to start without spatter and get a smooth weld every time.
