GMAW machines suitable for light-duty applications

Lincoln Electric's four new Power MIG®l 140 and 180 models offer a compact welding system for professional welders and home hobbyists alike.

The company's Diamond Core Technology® and a rugged drive system aid arc performance for MIG welding on thin gauge steel, stainless, and aluminum, or on gasless flux-cored welding for deep penetration on thicker steel, even outdoors, the company says.

The 140 models are designed to run on common 120 V household current. With an amperage range of 30 to 140 amps, you can weld single pass up to 10 ga. (0.135 in.) and perform self-shielded flux-cored multiple pass welds up to 5/16 in.

180 models run on 208 to 230 V input power and, with an amperage range of 25 to 180 amps, can weld single pass up to 3/16 in. and perform self-shielded flux-cored multiple pass up to in.

The machines are offered with two levels of voltage control.
