Home projects and repair, sheet metal autobody work and small shop welding—the POWER MIG® 140C designed for 120 volt household power does it all!


  • Diamond Core Technology™ - Delivers a forgiving arc, excellent out-of-position arc action, low spatter and a wide voltage sweet spot at a given wire feed speed for steel, stainless steel or aluminum.

  • Industrial Cast Aluminum Drive - Dual gear-driven drive rolls deliver positive traction. Patented split wire guides ensure optimal wire alignment and a brass-to-brass gun connection aids critical conductivity. A large industrial closed-design drive motor improves torque and enhances trouble-free performance.

  • No Hassle Tool-less Design - For input power changes, wire spool mounting, wire drive service and polarity changes.

  • Spool Gun Ready - Just remove the standard MIG gun and plug in the economical Magnum® PRO 100SG spool gun (optional) for enhanced aluminum wire feeding performance.

  • Toughest PC Board Protection in the Industry - “Potted” to seal sensitive components from the environment, “trayed” in a tough plastic tray to add rigidity and shock resistance.
