907741 - Miller XMT 350 FieldPro 6-Pack Rack System 460/575V

High-Efficiency Multi-Operator Welding Solution

The Miller XMT® 350 FieldPro™ with Polarity Reversing 6-Pack Rack (907741) is a premier solution for industrial environments requiring multiple welding arcs, such as construction sites, shipyards, and structural fabrication zones. This system houses six XMT 350 FieldPro power sources within a single, ruggedly constructed rack, streamlining logistics and electrical hookups. The rack is equipped with standard lift eyes and fork pockets, allowing for easy transportation by crane or forklift. It is pre-fused for 460/575 V input, ensuring compatibility with high-voltage industrial power grids while protecting the individual units.

Advanced ArcReach® Technology

At the core of this system is Miller's ArcReach technology, which fundamentally changes how operators interact with their power sources. By communicating through the weld cables, ArcReach eliminates the need for fragile and expensive control cords. Operators can adjust voltage and amperage directly at the wire feeder or remote, even when located hundreds of feet away from the rack. This capability significantly improves safety by reducing the need to traverse cluttered jobsites to make adjustments, thereby minimizing slip, trip, and fall hazards.

Polarity Reversing and Process Automation

The Polarity Reversing feature is a critical advancement for fleet compatibility and ease of use. It works in tandem with Auto-Process Select™ to automatically configure the power source to the correct weld process based on the polarity applied to the accessory. This prevents common errors, such as welding in the wrong process, and ensures consistent quality. Furthermore, Cable Length Compensation (CLC™) automatically adjusts the output voltage to account for the voltage drop across long cable runs, ensuring that the parameter set by the operator is exactly what is delivered to the arc.

Rugged Durability for Harsh Environments

Designed for the toughest field applications, the XMT 350 FieldPro units feature Wind Tunnel Technology™, which prevents abrasive dust and particles from damaging internal components. The rack itself provides physical protection and organization, reducing cable clutter and simplifying power distribution. With Tweco-style connectors, this system offers reliable, high-conductivity connections suitable for heavy-duty cycles.
