Smart Technology for Better Welds

Gone are the days of guessing your voltage and wire feed speed. The Millermatic 255 features a large 7-inch color LCD display with Auto-Set™ Elite. Simply input your material and thickness, and the machine provides a professional-grade starting point. You can also save your favorite custom settings using the Program Mode, ensuring consistent results every time you pull the trigger. The inclusion of Pulsed MIG technology allows you to weld thin materials with less warping and better puddle control, making out-of-position welds easier than ever.

Built for the Long Haul

Reliability is key, and the Millermatic 255 delivers with a robust 60% duty cycle at 230 Amps. It includes the ergonomic MDX-250 MIG gun, which features a comfortable rubber overmold and a ball-and-socket handle to reduce fatigue during long welding sessions. The AccuLock™ S consumables are designed for flawless wire feeding, reducing downtime caused by burnbacks or bird-nesting. With generator compatibility (12kW+), this welder is as effective in the field as it is in the shop.
