Description
Miller Millermatic 255 MIG Welder with EZ-Latch Single Cylinder Running Gear 951766
The Miller Millermatic 255 MIG welder with EZ-Latch single cylinder running gear is a complete 350 amp welding package that comes standard with pulsed MIG welding capability. The inverter design means that the Millermatic 255 is less than half the weight of its popular predecessor, the Millermatic 252. Auto-Set Elite technology allows you to use preset welding parameters based on metal thickness, shielding gas and welding wire type to achieve optimum welds. You can also set your voltage and wire feed speed manually, for a custom welding arc.
The Millermatic 255 comes complete with full color seven inch LCD screen with intuitive design and simple controls. In addition to built-in welding programs, the 255 can also store your custom welding programs. It seamlessly switches between welding with standard MIG gun or optional Spoolmatic spool gun. The 255 also features direct plug for XR push-pull gun for professional aluminum wire feed capability. This allows you to use 12 inch spools of aluminum MIG wire instead of the more expensive 1 lb rolls used with the spool gun.
EZ-Latch running gear with single cylinder cylinder rack gives unmatched portability to the Millermatic 255. For moving around the shop, the 255 attaches to the running gear through a series of four, quick-disconnect latches. For times when your 255 is taken into the field, the machine and running gear can be quickly separated for loading into a vehicle. The 255 can also be separated from the EZ-Latch running gear to access difficult-to-reach areas around the shop where a welder with full running gear/cylinder rack might not otherwise fit.
NOTE: EZ-Latch running gear comes in separate box and requires some assembly. Components assemble in three steps and include: cart with front caster wheels, cylinder tray with rear wheels and cylinder post.

Auto-Set Elite offers predefined weld settings to increase ease of use and ensure that the job is done right for operators of all skill levels. Available for MIG and pulsed MIG processes with the ability to fine-tune your settings. Set weld parameters by selecting wire and gas type, wire diameter and material thickness. Program mode allows easy save and recall offavorite weld settings. Deliver more productivityby eliminating the needto manually set theparameters. Deliver consistentquality by welders ofall skill levels by usingprequalified weld settings. Minimize supervisorneed to intervene.
Pulsed MIG welding delivers higher quality welds for ALL welders. Lower heat input for less distortion on thin materials and better puddle control on out-of-position welds. Less spatter minimizes post weld grinding and rework allowing more welding time. Perform welding applications that couldn’t be done in the past. Ideal for MIG welding aluminum and stainless steel.
Compatible with push-pull MIG guns. Increases productivity by allowing the use of 12-inch wire spools versus a spool gun’s 4-inch spools. Reduces downtime changing wire spools.
Auto-Line allows for any single-phase input voltage hookup (208-240 V) with no manual linking, providing convenience in any job setting. Ideal solution for dirty or unreliable power.
