The Miller Millermatic 255 is a 250-amp inverter pulsed MIG welder for MIG, flux-cored and pulsed MIG welding in light manufacturing and fabrication. This all-in-one machine connects to 208 or 240 V single-phase power, is rated 230 A at 25.5 V with a 60% duty cycle, and welds aluminum, stainless and mild steel up to 1/2 in. thick.

Maximum open-circuit voltage is 87 VDC and wire feed speed runs 50-800 IPM. It feeds .023-.045 in. solid steel, .023 in. stainless, .030-.045 in. flux-cored and .035-.047 in. aluminum wire from 12 in. spools, and Auto-Set Elite, program mode and a 7-inch color LCD keep setup quick. Pulsed MIG lowers heat input to limit distortion on thin material and reduces spatter and grinding.

The package includes a 10 ft (3 m) power cord, a 15 ft (4.5 m) 250-amp MDX-250 MIG gun for .035/.045 in. wire, fitted with Bernard AccuLock S consumables, a work cable and clamp with a 50 mm Dinse-style connector, a flow gauge regulator and gas hose, extra contact tips, reversible drive rolls and a material thickness gauge. The machine alone weighs 84 lb, can be mounted on EZ-Latch running gear, and delivers full output from generators of 12,000 watts or more.
