Miller Multimatic 255 Pulsed Multiprocess Welder W/Running Gear (208-575V) (951767)

Same pulsed MIG, flux-cored, DC stick, and pulsed TIG inverter as the base 255, except this build already sits on EZ-Latch running gear instead of leaving that as a separate add-on. Auto-Line electronics accept any single-phase feed from 208 to 575V without manual rewiring.

Who it suits

Rated for industrial and light-industrial jobs at the career-welder level, on mild steel and stainless steel, not aluminum. Bare, the power source weighs 84 pounds; attached to its running gear, the whole package comes to 180 pounds, trading a little portability for a cart that never has to be bolted on separately.

Before buying

Duty cycle here runs 60 percent at 235A, slightly higher than the bare 255's own rating, worth checking against the kind of passes you expect to run. The gun uses Bernard S Lock consumables that twist into place in one motion, and program mode saves settings you use often rather than making you redial them at the start of every shift.

Included hardware

This listing comes with the power source and its 10-foot cord (no plug attached) plus the single-cylinder running gear already attached. A feed gun purpose-built around the Bernard S Series consumable line handles wire feeding, backed by a pair of leads for work and ground, a regulator for shielding gas, spare contact tips, reversible drive rolls, and a thickness gauge.

Three-year warranty from Miller on this new unit.
