907777 - Miller XMT 350 CC/CV MigRunner Package with 20 Series Feeder

The Ultimate Mobile Workhorse

If you are looking for the industry standard in versatility and reliability, the Miller XMT 350 CC/CV MigRunner is the machine you want in your shop. Known affectionately by welders as the "Blue Box that does it all," the XMT 350 delivers an incredibly smooth, stable arc across every process—whether you are burning 7018 rod, running solid wire, or laying down TIG beads.

This specific package (907777) sets you up for success right out of the crate. It pairs the power source with the 20 Series Wire Feeder, a no-nonsense, industrial-grade feeder built to withstand the daily grind. The entire setup is mounted on the MigRunner Cart, which means you can roll your power, wire, and gas right to the workpiece without dragging cables across the floor or making multiple trips. It’s the definition of "grab and go" for heavy fabrication.

Built for the Real World

We know that power on job sites isn't always perfect. That's why the XMT 350 features Auto-Line technology. You can plug this machine into anything from 208V to 575V, single or three-phase, and it just works. No jumpers to move, no tools needed. If the voltage spikes or dips, the arc stays steady so your welds pass inspection.

The machine also takes care of itself. With Wind Tunnel Technology, the cooling air is routed specifically over heat sinks and away from sensitive electronics, so grinding dust and metal shavings don't short out your board. Whether you are gouging with 5/16-inch carbons or welding thin gauge stainless, the XMT 350 MigRunner gives you the power and control you need to get the job done right.
