907161 - Miller XMT 350 CC/CV Multiprocess Welder, 208-575V Auto-Line, Dinse

Industrial Multiprocess Power Source

The Miller XMT 350 CC/CV (Dinse #907161) represents the pinnacle of inverter-based welding technology for industrial applications. Designed to handle the rigors of heavy manufacturing, construction, and fabrication, this power source offers exceptional arc performance across multiple processes, including MIG (GMAW), Pulsed MIG (GMAW-P), Stick (SMAW), TIG (GTAW), Flux-Cored (FCAW), and Air Carbon Arc Cutting and Gouging (CAC-A). Its core advantage lies in the proprietary Auto-Line™ Power Management Technology, which allows for automatic connection to any input voltage ranging from 208 to 575 VAC, single or three-phase, with no manual linking required. This ensures consistent arc performance even when input power is dirty or unreliable.

Advanced Arc Control

The XMT 350 is engineered with features that enhance weld quality and ease of use. Adaptive Hot Start™ automatically increases output amperage at the start of a weld to prevent electrode sticking, ensuring smooth starts with Stick electrodes. For TIG applications, Lift-Arc™ allows for arc initiation without the use of high frequency, minimizing the risk of tungsten contamination. The machine also features infinite arc control in Stick and Wire modes, allowing operators to fine-tune the arc characteristics for specific materials and out-of-position welding.

Durability and Reliability

Miller has integrated Wind Tunnel Technology™ into the XMT 350, an internal airflow design that prevents particulate matter from settling on sensitive electronic components, significantly extending the machine's lifespan. Complementing this is the Fan-On-Demand™ cooling system, which operates only when necessary. This reduces noise, power consumption, and the amount of airborne contaminants pulled through the machine. The unit is housed in a robust case with an ultra-tough, polycarbonate-blended cover to protect the front controls from impact damage.

Connectivity and Specs

This model utilizes Dinse-style weld cable connectors for high-quality, secure electrical connections. It includes a standard 14-pin receptacle, providing compatibility with a wide range of Miller wire feeders, spool guns, and remote controls. With a net weight of just 80 lbs (36.3 kg), the XMT 350 offers a high power-to-weight ratio, making it easily portable around large job sites or shop floors.
