Lincoln Power MIG® 140 MP Multi-Process Welder
Portable. Powerful. Perfect for the Weekend Warrior.

The Lincoln Power MIG® 140 MP is the ideal 3-in-1 welder for DIYers, hobbyists, and anyone looking for professional versatility in a compact package. This multi-process powerhouse handles MIG, flux-core, stick, and DC TIG welding, giving you the freedom to tackle a wide range of materials and jobs with a single machine.

Operating on standard 120V household power and weighing only 34.5 lbs, the 140 MP is road-ready and jobsite-friendly. With an intuitive control setup, fast tool-less wire drive access, and smooth arc performance, it’s the perfect blend of ease and capability—whether you're welding in your garage or on the go.

⚠️ Note: DC TIG welding is suitable for mild steel and stainless steel only. To weld aluminum, you’ll need the SG100 Spool Gun (K4360-1), sold separately.
