Work Smarter with the Miller XMT 450 ArcReach

The Miller XMT 450 CC/CV 575V is the ultimate workhorse for professional welders who demand flexibility, power, and efficiency on the job site. Known for being one of the most popular models in the industry, the XMT 450 now features game-changing ArcReach® technology. This innovation puts control right at your fingertips, allowing you to adjust voltage and wire feed speed remotely using a compatible feeder or stick/TIG remote. No more walking hundreds of feet back to the power source to make adjustments—stay at the weld joint, keep your hood down, and get the job done faster. This feature alone can save hours of non-productive time over the course of a project.

Built for the Toughest Jobs

Whether you are gouging with 3/8-inch carbons or laying down precise MIG beads, the XMT 450 delivers consistent arc performance. The Auto-Process Select™ system is a massive time-saver; if you switch from gouging to a wire feeder, the machine automatically detects the change and updates the polarity and settings. You don't have to worry about incorrect settings ruining a weld. Plus, with the standard 14-pin receptacle, you retain full compatibility with your existing fleet of spool guns and remote controls, making this machine a versatile addition to any equipment lineup.

Reliability You Can Trust

Job sites are dirty, but your machine doesn't have to suffer. Miller's Wind Tunnel Technology™ prevents abrasive dust and metal shavings from damaging internal components, while Fan-On-Demand™ keeps the machine running cool and quiet. The impact-resistant case and protective cover for the controls mean this welder can take a beating and keep on performing. From structural steel to shipbuilding, the XMT 450 CC/CV is designed to help you weld smarter, not harder. Its portability and rugged design make it the go-to choice for welders who need a machine that works as hard as they do.
