PowerMTS 141Si

The PowerMTS 141Si is a versatile 120V all-in-one DC welder offering 140A MIG, 140A DC TIG, and 80A DC Stick capabilities. This compact unit provides full functionality for MIG, TIG, and Stick welding without compromising performance in any process.

The MIG feature supports welding Aluminum with an optional spool gun or Flux-Cored wire with the appropriate drive rolls. In TIG mode, it handles Steel, Stainless, and Titanium, with HF and Lift Start modes for precise arc control and the option for a foot pedal to adjust amperage. It includes automatic gas control and a separate gas inlet for TIG.

The Stick function supports popular 3/32" rods like E7014, E7018, and E6011 (not E6010). With a 140A rating, it welds steel and stainless steel up to 1/4" in multiple passes or 1/8" in a single pass.

The easy-to-use control panel with a bright LED display ensures user-friendly operation, and the 5-year warranty adds value to an already top-performing, portable welding solution.
