Miller XMT 350 CC/CV Auto-Line Multi-Process Welder

Portable enough for site work, capable enough for industrial production. The Miller XMT® 350 CC/CV Auto-Line™ is a compact multi-process inverter power source for fabrication, construction, maintenance and field repair across stick, MIG, flux-cored and Lift-Arc™ TIG welding.

Flexible power without manual relinking

Auto-Line technology accepts a wide range of input voltages and automatically adapts to the available supply, helping the XMT 350 perform reliably where incoming power is dirty or inconsistent. CC and CV output modes make it easy to move between electrode, wire and TIG processes without changing power sources.
