907742 - Miller XMT 350 FieldPro 4-Pack Rack Polarity Reversing System

Industrial Power and Portability for Large-Scale Operations

The Miller XMT 350 FieldPro 4-Pack Rack (907742) is the ultimate solution for heavy industrial applications such as construction, structural steel, and shipbuilding. Designed to streamline onsite logistics, this system houses four XMT 350 FieldPro power sources in a single, ruggedly constructed rack. By consolidating multiple power sources into one liftable unit, you significantly reduce the setup time and complexity associated with deploying individual welders across a job site. The rack features a standard lifting eye and forklift pockets, making it easy to move via crane or forklift, ensuring that power is always available exactly where it is needed.

Revolutionary ArcReach Technology

At the heart of this system is Miller's game-changing ArcReach technology. In traditional setups, welding operators waste hours traversing complex job sites—climbing ladders, navigating scaffolding, or walking hundreds of feet—just to adjust voltage or amperage at the power source. With ArcReach, these adjustments can be made directly at the wire feeder or remote, using the existing weld cables. There is no need for fragile and expensive control cables, which are prone to damage and costly repairs. This capability alone can save hundreds of labor hours per year per operator, directly boosting your bottom line.

Advanced Polarity Reversing

This specific configuration (907742) is equipped with Polarity Reversing technology. On multi-process job sites, switching between Stick (which might require DCEP) and TIG (DCEN) or Flux-Cored usually involves manually swapping heavy cables at the power source. The XMT 350 FieldPro with Polarity Reversing eliminates this step entirely. Operators can select the process at the feeder, and the power source automatically switches the output polarity. This feature, combined with Auto-Process Select, ensures that the correct weld process is always used, reducing the risk of weld defects and equipment damage.

Uncompromised Reliability

Built to withstand the harshest environments, the XMT 350 FieldPro units feature Wind Tunnel Technology, which prevents abrasive dust and particles from damaging internal components. The Fan-On-Demand cooling system operates only when needed, reducing noise and energy consumption. With Cable Length Compensation (CLC), the system automatically adjusts the output voltage to compensate for the voltage drop over long cable runs, ensuring that the voltage you set is the voltage you get at the arc, regardless of distance.
