Miller XMT 350 CC/CV Multiprocess Welder, 208-575V Auto-Line, Dinse

The Ultimate Workhorse for Any Job Site

When versatility and reliability are non-negotiable, professional welders turn to the Miller XMT 350 CC/CV. Known as one of the most popular MIG welding machines on the market, the XMT 350 is built to tackle everything from construction and shipbuilding to railcar manufacturing and heavy equipment repair. Its legendary performance is backed by Miller's True Blue® 3-Year Warranty, giving you peace of mind that your investment is protected.

Power Anywhere, Anytime

Forget about the hassle of rewiring your machine for different voltage inputs. With Miller's revolutionary Auto-Line™ Technology, the XMT 350 automatically adjusts to any primary power source between 208 and 575 volts, whether single-phase or three-phase. This means you can move from the shop to the field and plug in without worrying about manual linking or dirty power affecting your weld quality. It is the ultimate solution for welders who need a machine that adapts to their environment, not the other way around.

Versatility Meets Simplicity

The XMT 350 CC/CV isn't just a MIG welder; it's a complete multiprocess solution. Whether you are laying down heavy Flux-Cored beads, precision TIG welding stainless steel, or gouging with 1/4-inch carbons, this machine delivers a stable, smooth arc. The welder-friendly control panel features a simple process selector switch that reduces setup time, while large dual digital meters make it easy to preset and monitor your voltage and amperage. The Dinse-style connectors ensure a solid connection for your cables, reducing resistance and heat buildup.

Built for the Long Haul

Industrial environments are tough on equipment, but the XMT 350 is tougher. It features Miller's Wind Tunnel Technology™, which routes cooling air through a dedicated tunnel, keeping dust and grinding grit away from the circuit boards. Combined with Fan-On-Demand™, which keeps the fan off when the machine is cool, you get a quieter shop and a cleaner machine. Weighing in at only 80 lbs, it is portable enough to be carried by two people or wheeled on a cart, yet powerful enough to be the backbone of your welding operation.
