Everlast Lightning MTS 275 AC/DC TIG Pulse, MIG & Stick Welder with TIG Package

One machine. Three welding processes. Professional performance without compromise.
The Everlast Lightning MTS 275 combines AC/DC TIG, MIG, and Stick welding into one powerful multi-process platform. Designed for fabrication shops, maintenance departments, motorsports, mobile repair, and manufacturing, it delivers up to 275 amps of output with advanced digital controls, synergic setup assistance, and an impressive 60% duty cycle at maximum output.

Whether you're MIG welding steel, TIG welding aluminum, or burning 3/16" Stick electrodes in the field, the Lightning MTS 275 eliminates the need for multiple welders while giving you the control expected from dedicated machines.

Why Welders Choose the Lightning MTS 275
