Miller Xmt 350 Fieldpro Arcreach 4-PACK Rack (907739)

This rack bundles four Miller XMT 350 FieldPro ArcReach welders onto one mobile frame, built for a crew that needs several operators striking an arc on the same jobsite at once. Each XMT handles stick, MIG, TIG, and flux-cored work, and ArcReach lets a welder dial in settings from the wire feeder instead of walking back to the power source.

What the rack is built for

Auto-line sensing covers 208 through 575 volts, and every unit runs on single- or three-phase power, so the rack drops onto almost any job site without rewiring. Cable length compensation keeps the arc steady even when leads run long between the power source and the work. Adaptive hot start and infinite arc control carry over here too, together with lift-arc starting and fan-on-demand cooling, standard across every unit in the rack.

What to check before ordering

Confirm your site has single- or three-phase service in that voltage range, and plan feeder and lead runs around the Tweco-style connectors each XMT uses. Loaded with all four welders, the rack weighs 520 pounds; pull one XMT 350 FieldPro off the rack on its own and it weighs 93 pounds. Peak amperage reaches 425, and the duty-cycle rating lands at 60 percent, 350 amps on three-phase power or 300 amps single-phase.

Q: Can one operator run all four welders? No, the rack is built for four separate operators working at once, each with ArcReach control from their own feeder.

Q: Does it need a separate control cord run? ArcReach is designed to remove that control-cord run between feeder and power source across a fleet of ArcReach-equipped machines.

New condition, Miller's three-year warranty, and the California Prop 65 notice that applies to most welding equipment of this kind round out the basics. See our welding equipment lineup for single-unit ArcReach packages if your crew needs fewer stations.
