OVERVIEW

Heavy-Duty Industrial Multiprocess Power Source

The Miller XMT 450 CC/CV 230/460V with ArcReach and Auxiliary Power (907481004) is engineered for the most demanding industrial environments. Delivering a rated output of 450 Amps at 100% duty cycle, this inverter-based power source offers exceptional performance across MIG (GMAW), Stick (SMAW), TIG (GTAW), Flux-Cored (FCAW), and Air Carbon Arc Cutting and Gouging (CAC-A) processes. It is specifically designed to handle 3/8-inch carbons for gouging applications, making it a versatile asset for shipbuilding, construction, and heavy fabrication.

ArcReach Technology Integration

This unit features Miller's exclusive ArcReach technology, which enables communication between the power source and compatible wire feeders or remotes using existing weld cables. This eliminates the need for fragile and expensive control cords, significantly reducing setup time and maintenance costs. Operators can adjust voltage and wire feed speed directly at the weld joint, improving safety by reducing trips back to the power source.

Advanced Reliability and Control

The XMT 450 utilizes Wind Tunnel Technology™ to direct internal airflow over power conversion components while protecting sensitive electronics from dirt, dust, and debris. The Fan-On-Demand™ cooling system operates only when necessary, minimizing noise and reducing the intake of airborne contaminants. For precise arc control, the unit includes Adaptive Hot Start™ for Stick welding, Lift-Arc™ for TIG starting without high frequency, and SharpArc® for optimizing the arc cone in Pulsed MIG applications. The inclusion of a 115 VAC, 10 Amp auxiliary power receptacle adds convenience for running water cooling systems or small tools directly from the welder.

FAQ

This model (907481004) requires 3-Phase input power at either 230V or 460V.

Yes, it features ArcReach technology, which allows remote control of voltage and amperage through the weld cables when paired with an ArcReach feeder or remote.

The XMT 450 is rated at 450 Amps at 38 VDC with a 100% duty cycle.

Yes, the XMT 450 is capable of Air Carbon Arc Gouging and is rated for carbons up to 3/8 inch (9.5 mm) in diameter.

Yes, it includes a standard 115 VAC, 10 Amp receptacle on the rear for powering accessories like water coolers.

It is a multiprocess welder capable of MIG (GMAW), Pulsed MIG (with compatible feeder), Stick (SMAW), TIG (GTAW), Flux-Cored (FCAW), and Carbon Arc Gouging (CAC-A).

The net weight of the power source is 122 lbs (55.3 kg).

Auto-Process Select automatically changes the XMT's mode based on the connected accessory. For example, connecting an ArcReach feeder switches it to MIG/FCAW; disconnecting it returns it to the previous setting (e.g., Gouging).
