907731 - Miller XMT 350 FieldPro Polarity Reversing Multi-Process Welder (Tweco)

Stop Walking, Start Welding

Time is money on the job site, and the Miller XMT 350 FieldPro Polarity Reversing Welder is built to save you both. If you've ever had to climb down five stories of scaffolding just to swap your leads from DCEP to DCEN, you know the struggle. This machine fixes that. With built-in Polarity Reversing, you can switch from burning Stick electrodes to running TIG or MIG without ever touching the power source. Just hit the button on your ArcReach feeder or remote, and the machine handles the switch internally. No more cable clutter, no more wasted trips, and no more downtime.

Total Control at the Arc

The XMT 350 FieldPro puts the control where it belongs: in your hands. Thanks to ArcReach technology, your wire feeder or remote communicates with the power source right through the weld cables. You can adjust your voltage and amperage, and even switch processes, from hundreds of feet away. The Adjust While Welding (AWW) feature lets you fine-tune your heat while you're laying a bead, giving you the precision you need for critical X-ray quality welds. Plus, with Cable Length Compensation, the machine automatically boosts the output to make up for voltage drop over long leads, so the heat you set is the heat you get.

Built for the Grind

This isn't a shop toy; it's a field warrior. Weighing in at just 93 pounds, it's easy to haul around the site. It runs on practically any power you can find, from 208V to 575V, thanks to Auto-Line. The Wind Tunnel Technology keeps the guts of the machine clean by blowing air through a dedicated tunnel, not over the circuit boards, so grinding dust and dirt won't kill your welder. Whether you are gouging with 5/16" carbons or running RMD on open roots, the XMT 350 FieldPro with Tweco connectors is ready to work as hard as you do.
