907479001 - Miller XMT 450 MPa Multiprocess Welder 230/460V

Versatility and Power for the Professional Welder

Take your welding projects to the next level with the Miller XMT 450 MPa Multiprocess Welder. Known for its reliability and exceptional arc performance, the XMT family is a staple in the industry, and the 450 MPa model delivers even more power and versatility. Whether you are working on a construction site, in a railcar facility, or a high-production fabrication shop, this machine handles it all—MIG, Stick, TIG, and Flux Cored welding—with ease. Its 230/460V 3-phase input versatility ensures it integrates seamlessly into most industrial power grids.

Superior Welds with Less Effort

The "MPa" stands for MIG, Pulse, and Advanced Arc Control, and this machine lives up to the name. It comes loaded with built-in pulse programs that make welding aluminum and stainless steel easier than ever. The SharpArc® feature gives you total control over the arc, allowing you to flatten the weld bead and increase puddle fluidity for a perfect finish. When used with optimized feeders, you can even achieve a TIG-like "stacked dimes" appearance with the simplicity and speed of MIG welding using Profile Pulse™. This means less post-weld cleanup and higher productivity for your business.

Built Tough for the Job Site

Miller knows that job sites can be tough on equipment. That's why the XMT 450 MPa features a lightweight, aerospace-grade aluminum case that offers heavy-duty protection without the heavy weight. The control panel is protected by an ultra-tough polycarbonate cover, and the internal components are shielded by Wind Tunnel Technology™ to keep out grinding dust and dirt. Plus, with the added benefit of 115V auxiliary power right on the back of the machine, you can easily plug in a Coolmate™ water cooler or your grinder without hunting for another outlet.

User-Friendly Interface

Despite its advanced features, the XMT 450 MPa is designed to be welder-friendly. The process selector switch simplifies setup, reducing the number of combinations you need to dial in. Large, dual digital meters are easy to read even in low light, and they can be preset to ensure you hit your target parameters every time. Backed by Miller's True Blue® 3-Year Warranty, this is an investment in quality that pays for itself in performance and durability.
