907481 - Miller XMT 450 CC/CV Industrial Multiprocess Welder, 230/460V 3-Phase

Heavy-Duty Industrial Multiprocess Welding Power Source

The Miller XMT 450 CC/CV (907481) is a premier choice for industrial manufacturing, fabrication, and construction environments requiring robust power and versatility. Engineered to deliver a rated output of 450 Amps at 100% duty cycle, this machine is built to withstand the most demanding production schedules without overheating or faltering. It supports a comprehensive range of processes including MIG (GMAW), Stick (SMAW), DC TIG (GTAW), Flux-Cored (FCAW), and Air Carbon Arc Cutting and Gouging (CAC-A), making it a singular solution for diverse fabrication needs. Its 3-phase input capability (230/460 V) ensures stable, high-efficiency power delivery essential for heavy structural work.

Reliability is at the core of the XMT 450's design. It features Miller's proprietary Wind Tunnel Technology™, which directs internal airflow over power components that require cooling while shielding sensitive electronic boards and parts from dirt, dust, and debris. This significantly extends the lifespan of the unit in dirty shop environments. Complementing this is the Fan-On-Demand™ cooling system, which operates only when necessary. This reduces the amount of airborne contaminants pulled through the machine, lowers noise levels for a safer work environment, and decreases energy consumption, contributing to lower operational costs over time.

For precise control, the XMT 450 includes Line Voltage Compensation (LVC™), which keeps welding output constant even if input power varies by +/- 10%, ensuring consistent weld quality. The unit is housed in a lightweight, aerospace-grade aluminum case, offering superior protection while maintaining portability at just 122 lbs. The standard 14-pin receptacle provides seamless integration with a wide variety of wire feeders, spool guns, and remote controls, allowing for flexible system configurations tailored to specific project requirements. With a max open-circuit voltage of 90 VDC and a wide amperage range of 15-600 A, the XMT 450 CC/CV is a powerhouse designed to maximize productivity and minimize downtime.
