Miller Xmt 350 Fieldpro Arcreach

Rather than a single stand-alone machine, this XMT 350 FieldPro listing (907740) ships as a rack of six multi-process welders, built for field jobs where several operators need to weld at once from one mobile setup.

Who this suits

Each unit in the rack runs MIG, flux-cored, stick, or TIG on mild steel or stainless steel, and Auto-Line hardware accepts single- or three-phase input anywhere from 208 to 575V without manual rewiring — useful when a crew plugs into whatever power a site happens to offer. ArcReach lets operators adjust output from the feeder or a remote instead of walking back to the power source, riding on the existing weld cable rather than a separate control cord.

Before buying

Output spans a 10 to 38V, 5 to 425A range, with duty cycle rated at 60 percent at 350A on three-phase power or 60 percent at 300A on single-phase. The 769-pound weight listed covers the entire rack with all six welders mounted, not one unit on its own, so plan rigging and placement with that in mind rather than assuming a single-person lift.

Build and connections

Cases are lightweight, aerospace-grade aluminum with dual digital meters and a process-selector switch on each welder, and connections use Tweco-style fittings throughout the rack.

Does each welder need its own remote control? Auto Remote Sense detects a connected remote receptacle automatically on each unit.

Three-year Miller warranty included.
