Miller® Millermatic® 255 MIG Welder 907734

The Miller® Millermatic® 255 MIG welder is a complete 250 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.

Program mode allows easy save and recall of favorite weld settings. Deliver more productivity by eliminating the need to manually set the parameters. Deliver consistent quality by welders of all skill levels by using prequalified weld settings. Minimize supervisor need 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 couldnt be done in the past. Ideal for MIG welding aluminum and stainless steel.

    great machine does everything its supposed to. auto-set is perfect no need for adjustment, spoolgun performance is so much more advanced than older models its like tig welding but with wire very good penetration and tie ins no more stack up put on auto-set and the machine controls wire speed incredible great machine, affordable, professional, get one.
    Prosexcellent no issues

    big upgrade!
    March 21, 2019
    this machine is my step up up from my 211. I could not be happier. The new 15' bernard gun. yea theres a screen full of settings like a new car but once you find your sweet spot this machine gets to work. pays for itself. I did not want to get the multiprocess because thats not for me I have a better acdc tig. machine is light enough to pick up and put in your truck or van or whatever welding rig your running.
