Millermatic 180 all-in-one MIG welder replaces the Millermatic 175 and includes Miller Electric’s Smooth Start technology that initiates the arc in a more controlled manner. The result is smooth, spatter-free starts, the company says. The welder has single-phase 230-v input and 135-amp at 22VDC, 30-percent duty cycle output. It can weld 5/16-inch mild steel in a single pass, the company says.
