Lincoln Power MIG® 140 MP Multi-Process Welder
Portable Power. Versatile Performance.

The Lincoln Power MIG 140 MP is the perfect solution for the weekend warrior, hobbyist, or DIY enthusiast seeking a compact, multi-process welder with big-time capability. Weighing only 34.5 lbs and powered by a standard 120V outlet, this lightweight, highly portable unit goes wherever the work takes you—garage, jobsite, or on the road.

True Multi-Process Flexibility
The Power MIG 140 MP is a 3-in-1 machine that supports MIG, Flux-Core, Stick, and DC TIG welding—all in a single compact package. It welds up to 3/16" thick material in a single pass, making it ideal for light fabrication, automotive work, farm repairs, and metal art. The DC TIG mode (with optional torch and foot pedal) is suited for mild steel and stainless steel. For those looking to weld aluminum, the unit is spool gun compatible with the optional SG100 (K4360-1) spool gun.

Simple Controls, Pro Results
Designed for ease of use, the Power MIG 140 MP features a simple two-knob control system and a single-button process selector, making setup quick and intuitive for beginners and experienced welders alike. The tool-less drive roll changeover and spool gun switch provide additional convenience and adaptability.
