Miller Millermatic 255 Mig/Pulsed MIG Welder- 208/240V (907734)

The Millermatic 255 is a 208/240-volt MIG and pulsed-MIG inverter built for light manufacturing and fabrication rather than home-shop use, with a color LCD display for dialing in settings. It runs on single-phase power at either 208 or 240 volts without manual relinking.

Capacity and portability

This unit's duty cycle field reads 60% at 230A at 25.5V, and the machine weighs 84 lbs, lighter by more than fifty percent than Miller's older 252 model, so it can come off its running gear for tighter work cells rather than always rolling on a cart. Auto-Set Elite stores favorite weld settings so less-experienced operators can start from a proven setup.

Setup and material

It welds aluminum, mild steel, and stainless with MIG, pulsed MIG, and flux-cored processes, and EZ-Latch running gear lets it be unlatched from the cart without a lift truck. It ships with a power cord, a MIG gun sized for .035/.045 in wire, a work cable and clamp with a 50 mm Dinse connector, a flow gauge regulator and gas hose, extra contact tips, reversible drive rolls, and a thickness gauge.

Is this a beginner machine? It is built more for light manufacturing and fabrication, suited to weekend-warrior and career-welder skill levels rather than a first-time hobbyist.
