OVERVIEW

Maximize Jobsite Productivity with the Miller XMT 350 FieldPro Rack

Take control of your large-scale welding projects with the Miller XMT® 350 FieldPro™ 6-Pack Rack. This powerhouse system is designed to deliver six independent arcs from a single, portable unit, making it the ultimate choice for contractors who need to mobilize quickly and efficiently. Whether you are working on a high-rise, a bridge, or a ship, this rack system reduces the complexity of power distribution and equipment setup. The 460/575 V fused input means you only need one primary power connection to run six welders, saving time on electrical installation.

Work Smarter, Not Harder

Time is money on the jobsite, and the XMT 350 FieldPro Rack saves both. Thanks to ArcReach® technology, your welders can make precise adjustments to their settings right at the weld joint. No more walking back to the power source to change amperage or voltage. This "Adjust While Welding" (AWW™) capability allows for immediate parameter correction, leading to better weld quality and fewer defects. The result is more arc-on time and less downtime spent moving around the site.

Eliminate Guesswork and Errors

Quality control is built into the system. The Polarity Reversing feature and Auto-Process Select™ ensure that the machine is always set to the right mode for the job. If a welder switches from Stick to MIG, the machine detects the change and adjusts automatically. Additionally, the Cable Length Compensation (CLC™) feature guarantees that the voltage you set is the voltage you get, regardless of how far away you are from the rack. This consistency reduces training time for new operators and minimizes rework caused by inconsistent power delivery.

Built for the Long Haul

Invest in equipment that lasts. The Miller XMT 350 FieldPro Rack is built to withstand the rigors of outdoor and industrial use. The heavy-duty rack frame protects the welders during transport, while the internal Wind Tunnel Technology™ keeps the power sources running cool and clean. With a 3-year True Blue® warranty, you can trust this system to perform reliably project after project. Equip your fleet with the industry standard for multi-operator welding efficiency.

FAQ

The rack is fused and wired for 460/575 V operation, accommodating common high-voltage industrial power supplies.

This system includes six (6) Miller XMT 350 FieldPro power sources mounted in a single rack.

Yes, it features ArcReach technology, allowing remote parameter adjustments via the weld cables when paired with compatible feeders or remotes.

Polarity Reversing allows the power source to automatically switch between welding processes (like Stick and MIG) based on the connected accessory, without manual cable swapping at the machine.

The rack is equipped with standard lift eyes for crane transport and fork pockets for movement by forklift.

This specific model (907741) is equipped with Tweco-style output connectors.

CLC automatically adjusts the output voltage to compensate for voltage drop over long cable runs, ensuring the set voltage matches the actual arc voltage.

Yes, the XMT 350 FieldPro power sources support Air Carbon Arc Cutting and Gouging (CAC-A) along with MIG, TIG, and Stick processes.
