Miller Xmt 350 Mpa Multiprocess Welder with Auxiliary Power (907366011)

The XMT 350 MPA pairs Miller's multiprocess power source with a built-in auxiliary power output, giving a welder stick, MIG, TIG, and flux-cored capability plus a power tap on the same machine. At 80 pounds, it is the lightest XMT 350 configuration in this lineup, and it is rated to run aluminum, mild steel, stainless steel, or titanium.

Who this configuration suits

Career welders who move between materials, including titanium work that not every multiprocess machine is rated for, get one power source that auto-senses voltage across 208, 230, 400, 460, or 575, rather than needing a dedicated setup for each job. Its built-in auxiliary power output lets the same unit run support equipment on site without a separate generator.

Output and duty cycle

Peak output sits at 425 amps, holding a 60 percent duty cycle up to 350 amps on three-phase wiring, or 300 amps when wired single-phase. Because this configuration is the power source on its own, without a bundled remote control or wire feeder, it suits a shop or service truck setup where the welder works at the machine rather than running a feeder at a distance.

Q: Does it include a wire feeder? No, this is the power source itself with auxiliary power; a feeder would be sourced separately for MIG work.

Q: Is it rated for titanium? Yes, titanium is listed alongside aluminum, mild steel, and stainless steel for this machine.

New condition, a three-year warranty from Miller, and a California Prop 65 notice round out the basics on this power source. See our welding equipment category for other XMT configurations with different portability features.
