Lincoln Power MIG® 140 MP Multi-Process Welder
Portable Power for Weekend Warriors and DIY Pros

The Lincoln Power MIG® 140 MP is the perfect multi-process welder for hobbyists, DIYers, and mobile welders who want capability without complexity. With MIG, flux-cored, stick, and DC TIG functions all in one compact machine, the 140 MP delivers serious versatility powered by a standard 120V household outlet.

Out of the box, it’s ready for MIG and stick welding—and with optional accessories, it can easily tackle TIG and aluminum spool gun welding. Weighing in at just 34.5 lbs, this unit is made for portability without sacrificing performance.

⚠️ Note: DC TIG is compatible with mild and stainless steel only. For aluminum welding, a Lincoln SG100 Spool Gun (K4360-1) is required (sold separately).
Optional TIG torch and foot pedal also sold separately.
