Miller XMT 350 Multi Process Welder – 5-425A Amp Range, P/N 907366011

Weld structural steel and pressure piping with the classic Miller XMT 350 CC/CV multi process welder (P/N 907366011) using standard 14-pin remote wire feeder connections. Automated manufacturing cells and fixed shop workbenches often rely on standard 14-pin control cables to link boom-mounted wire feeders and foot pedals to power sources. This 425-amp industrial inverter features a standard 14-pin Amphenol receptacle, Auto-Line power management, and constant current/constant voltage (CC/CV) multi-process arc programming.

Auto-Line technology accepts single-phase or three-phase primary power from 208V to 575V without internal manual jumper links. In CC mode, Adaptive Hot Start delivers smooth electrode strikes with 7018 low-hydrogen rods, while DIG control adjusts arc stiffness to penetrate root gaps. In CV mode, the powerhead outputs flat voltage characteristics that drive commercial benchtop wire feeders with high wire feed consistency, laying down flat, spatter-free beads on heavy structural beams.

Engine Architecture of Miller XMT 350 (P/N 907366011)

- Standard 14-Pin Receptacle Interface: Connects to industrial wire feeders, remote hand controls, and foot pedals with standard control cables.
- 5-425A CC/CV Output Capability: Supplies heavy multi-process power for MIG, Flux-Cored, Stick, and DC Lift TIG welding.
- Auto-Line Universal 208V to 575V Input: Connects to single-phase or three-phase shop power lines without internal reconnection jumpers.
- Rated 350A Output at 60% Duty Cycle: Maintains non-stop high-deposition spray-arc welding on heavy equipment brackets.
- Wind Tunnel Technology Cooling: Protects internal circuit boards from airborne metal shavings by directing air through a central duct.
- Fan-On-Demand Cooling System: Operates cooling fans only when heatsinks require cooling, reducing internal dust ingestion.

Commercial Advantages & Heavy-Duty Build

Built for structural manufacturing plants and multi-operator rack systems, this CC/CV powerhead delivers extreme duty-cycle stamina.

- Standard 14-pin remote receptacle provides complete compatibility with existing shop wire feeders and robotic automation controls.
- Inverter power conversion draws lower primary current than conventional transformer powerheads, lowering monthly factory utility bills.

Property Clearance & Trailer Packing

Measuring 24 inches long by 12.5 inches wide and weighing 80 pounds dry, this industrial powerhead fits on existing factory workbenches or mounts into 4-pack construction cages.

Warranty Protection & Routine Upkeep

- Miller Electric covers the XMT 350 power source with a 3-Year True Blue warranty against electrical component defects.

Clean internal cooling passages every 100 hours with dry shop air, verify secondary cable connection tightness, and check primary electrical connections annually.
