It operates on both three-phase and single-phase input power and features Miller’s Auto-Line, which means you use 208 volt to 575 volt, single or three-phase input power without manual linking. Weighing just 80 pounds, the XMT 350 CC\/CV is easy to move around the shop or jobsite and its rugged case design ensures it will stand up to the punishment of extreme work environments. It is ideal for industrial applications. It is able to carbon arc gouge with carbons up to 5\/16″ diameter. When paired with a wire feeder or spool gun, the XMT 350 CC\/CV makes an excellent MIG and Flux-Cored welder. It’s got built-in Lift-Arc TIG arc starting for smooth DC TIG arc starts without the use of high frequency.\u003c\/p\u003e\n\u003ch5\u003eWhat our Experts Think\u003c\/h5\u003e\n\u003cdiv
