Miller XMT 350 CC/CV Multiprocess Welder with Aux Power and Dinse Connectors

The Professional Welder's Choice for Flexibility

Take command of your welding projects with the Miller XMT 350 CC/CV, a machine that combines portability with exceptional arc performance. Known as the most popular model in the XMT family, this welder is designed with the operator in mind, featuring a welder-friendly control panel that simplifies setup. The process selector switch reduces the number of control combinations needed without sacrificing features, allowing you to switch between MIG, Stick, and TIG processes efficiently. The ultra-tough, polycarbonate-blended cover protects the front controls from impact and damage, ensuring your machine survives the roughest job sites.

Arc performance is where the XMT 350 truly shines. For Stick welding, the Adaptive Hot Start™ technology automatically increases the output amperage at the start of a weld if necessary, preventing electrode sticking and eliminating inclusion defects. When TIG welding, the Lift-Arc™ feature allows for arc starting without the use of high frequency, minimizing the risk of tungsten contamination. These advanced features give you the confidence to tackle tough-to-weld materials and complex joints with ease.

Convenience and Power Where You Need It

One of the standout features of this model is the integrated Auxiliary Power, which allows you to plug in grinders, coolers, or lights directly to the welder, saving you from running extra extension cords. The Auto-Line™ technology is a game-changer for mobile welders, as it automatically adjusts to whatever input power is available—from 208V to 575V—making hookup simple and safe. No more opening the case to move jumpers; just plug in and weld.

Weighing in at just 80 lbs, the XMT 350 is portable enough to be moved around the shop or hoisted onto scaffolding. The standard 14-pin receptacle offers the flexibility to connect various remote controls and wire feeders, including spool guns for aluminum work. With the ability to gouge using up to 1/4-inch carbons, this machine is a true workhorse. Whether you are in the shop or out in the field, the Miller XMT 350 CC/CV provides the consistent, high-quality arc you need to get the job done right.
