Miller Multimatic 255 Multiprocess Welder with Dual Cart and TIG Kit (208-575 V)
This Multimatic 255 package adds an EZ-Latch dual cylinder cart with an elevated gun and cable holder, plus a TIG kit, to the 84 lb multiprocess welder. The kit brings a 25 ft air-cooled A-150 TIG torch and a 20 ft RFCS-14 foot control, and Auto-Line accepts single-phase input from 208-575 V.
The TIG kit consists of a 25 ft air-cooled A-150 torch, an RFCS-14 foot control with a 20 ft cord, a 10-pin to 14-pin adapter cord, a regulator with 5 ft gas hose and an AK1C torch accessory kit. The cart is an EZ-Latch dual cylinder design with an elevated rack that holds the gun and cables.
The welder runs MIG, pulsed MIG, flux-cored, DC stick, DC Lift-Arc and pulsed TIG from a 7-inch color LCD. Auto-Line hooks up to any single-phase voltage between 208 and 575 V without relinking, Pulsed MIG brings lower heat input for thin material, Program mode saves favorite weld settings, and Auto-Set Elite supplies predefined settings.
