Miller XMT 350 Multi Process Welder – 5-425A Amp Range, P/N 907366014

Prevent auxiliary tool power dropouts on structural welding decks using the Miller XMT 350 multi process welder (P/N 907366014) with an onboard 115V auxiliary power receptacle. Workshop welders lose time running separate 120V extension cords across fabrication bays just to power water coolers, small angle grinders, or wire feeder heaters. This specialized 425-amp multi-process machine features a factory-installed 115V auxiliary power outlet, Auto-Line power management, and full CC/CV arc controls.

The dedicated 115V auxiliary outlet supplies 10 amps of electrical current to run water coolers directly beneath the powerhead without secondary wall drop cords. Auto-Line technology connects to single-phase or three-phase shop power from 208V to 575V, holding arc voltage steady despite plant electrical line surges. The multi-process powerhead delivers crisp DC stick arcs for 6010 pipe roots, smooth pulsed MIG wire deposition, and stable TIG puddles on structural steel assemblies.

Key Engineering Features of Miller XMT 350 (P/N 907366014)

- Dedicated 115V Auxiliary Power Receptacle: Powers water circulators and small auxiliary hand tools directly from the power source.
- 5-425A Multi-Process Output Window: Handles Stick, DC TIG, MIG, Flux-Cored, and Carbon Arc Gouging with 5/16-inch carbons.
- Standard 14-Pin Remote Connection: Integrates with standard industrial wire feeders, remote hand controls, and foot pedals.
- Auto-Line 208V to 575V Input Sensing: Operates on single-phase or three-phase industrial electrical services without manual rewire.
- Rated 350A Output at 60% Duty Cycle: Sustains continuous production welding passes with heavy solid and flux-cored wire.
- Wind Tunnel Component Isolation: Protects internal circuit boards from airborne metal shavings by directing air through a central duct.
- Digital Amperage and Voltage Meters: Displays exact real-time welding parameters for procedure compliance.

Fleet Productivity & Cost of Ownership

Engineered for fabrication shops and structural manufacturing, this auxiliary-powered inverter streamlines welding workstation setup.

- Onboard 115V outlet simplifies water-cooled TIG and MIG workstation setup, eliminating secondary 120V drop cords across work aisles.
- Inverter power conversion draws lower primary current than conventional transformer powerheads, lowering monthly factory utility bills.
- Wind Tunnel isolation prevents conductive iron dust from shorting internal power switches during heavy fabrication shifts.

Chassis Compatibility & Transport Dimensions

Weighing 80 pounds dry with an exterior length of 24 inches, this industrial inverter power source mounts on custom mobile carts, welding tables, or truck toolboxes.

Factory Warranty & Maintenance Guidelines

- Miller Electric backs the XMT 350 powerhead with a 3-Year True Blue warranty covering internal inverter modules and control boards.
- Authorized Miller service centers provide nationwide technical support and genuine replacement parts.

Blow dry compressed air through the powerhead cooling tunnels every 100 operating hours, check output cable lugs for heat discoloration, and test the 115V auxiliary outlet fuse periodically.
