OVERVIEW

Advanced Multiprocess Welding Solution for Field Applications

The Miller XMT® 350 FieldPro™ with Polarity Reversing and Dinse® connectors (907731002) represents a significant leap forward in industrial welding technology. Engineered specifically for the rigorous demands of pipeline, construction, and shipbuilding industries, this power source integrates intelligent connectivity with robust hardware. The defining feature of this unit is its Quick-Select™ technology, which automatically configures the correct polarity based on the selected process. This eliminates the need for operators to manually switch welding cables when transitioning between Stick, MIG, and TIG processes, thereby reducing setup time and minimizing the risk of connection errors.

Central to the FieldPro's efficiency is Miller's ArcReach® technology. This system allows the power source to communicate with remote wire feeders and Stick/TIG remotes directly through the welding leads. By removing the need for auxiliary control cables, the XMT 350 FieldPro reduces jobsite clutter and eliminates the maintenance costs associated with damaged control cords. Operators can adjust voltage and amperage at the point of the weld, significantly improving productivity and safety by reducing trips back to the power source. The unit also features Cable Length Compensation (CLC™), which automatically adjusts the output voltage to account for voltage drop over long cable runs, ensuring that the parameters set by the operator are exactly what is delivered to the arc.

The machine is built on Miller's proven inverter platform, featuring Auto-Line™ technology that accepts any input voltage from 208 to 575 VAC, single- or three-phase, without manual linking. This flexibility makes it a universal solution for sites with fluctuating or varied power infrastructure. Housed in a lightweight, aerospace-grade aluminum case, the XMT 350 FieldPro is designed for portability without sacrificing durability. Wind Tunnel Technology™ routes air flow to protect internal components, while Fan-On-Demand™ ensures the cooling system operates only when necessary. With Dinse® connectors providing secure, high-conductivity cable attachments, this welder is ready for the most demanding industrial environments.

FAQ

Polarity Reversing allows the machine to automatically switch between DCEN and DCEP based on the selected process, eliminating the need to manually swap weld cables.

No, when paired with ArcReach accessories, it communicates control signals through the welding leads, eliminating the need for separate control cords.

It features Auto-Line technology, accepting any input voltage from 208 to 575 VAC, single- or three-phase, 50/60 Hz.

CLC automatically adjusts the output voltage to compensate for voltage drop across long weld cables, ensuring the set voltage matches the actual arc voltage.

Yes, the XMT 350 FieldPro is rated for carbon arc gouging with carbons up to 5/16 inch in diameter.

This model (907731002) uses Dinse® style weld disconnects for secure and efficient cable connections.

Yes, it works with standard feeders, but ArcReach benefits (remote control without cords) are only available when paired with ArcReach-compatible feeders.

The machine provides an amperage range of 15 A to 425 A.
