The Miller XMT 450 CC/CV 230/460V with ArcReach technology (907481003) represents the pinnacle of industrial multiprocess welding performance. Designed for heavy-duty fabrication, construction, and shipbuilding, this power source delivers a massive 450 Amps at 38 Volts with a 100% duty cycle. This ensures that operators can weld continuously throughout the day without hitting thermal limits, providing 17,100 watts of welding power for the most demanding applications.
A defining feature of this unit is Miller's ArcReach technology. When paired with an ArcReach-compatible wire feeder or remote, the XMT 450 communicates control signals directly through the welding leads. This eliminates the need for fragile and expensive control cables, which are often the point of failure on job sites. Operators can adjust voltage and amperage right at the weld joint, significantly improving productivity and safety by reducing trips back to the power source.
Miller has engineered the XMT 450 for extreme environments. It features Wind Tunnel Technology, an internal airflow design that prevents dirt, dust, and debris from contacting sensitive electrical components and PC boards. Complementing this is the Fan-On-Demand cooling system, which operates only when necessary. This reduces noise, power consumption, and the intake of airborne contaminants. The unit is housed in a lightweight, aerospace-grade aluminum case that offers superior protection while keeping the net weight to a manageable 122 lbs.
This machine is a true multiprocess workhorse, capable of MIG (GMAW), Stick (SMAW), DC TIG (GTAW), Flux-Cored (FCAW), and Air Carbon Arc Cutting and Gouging (CAC-A). It supports carbon diameters up to 3/8 inch for effective gouging. With features like Adaptive Hot Start for Stick and Lift-Arc for TIG, the XMT 450 ensures high-quality arc starts and stable performance across all processes.
