Miller Multimatic 255 Multiprocess Welder 907728

The Miller Multimatic® 255 multi-process welder is a 350 amp portable welder. It is capable of DC Pulsed TIG, DC TIG, Stick, MIG and Pulsed MIG welding. This welder comes with a 7 inch LCD screen display with Auto-Set™ Elite technology capable of setting TIG, Stick and MIG parameters requiring only the metal thickness and welding wire or tungsten electrode diameter. The 255 also is capable of storing your custom welding programs, effortlessly switching between welding with a standard MIG gun or an optional Spoolmatic™ spool gun. It also includes direct plug for XR push-pull gun for professional wire feed. Running on 208-575 volt input power, the Miller Multimatic® 255 uses Millers Auto-Line technology to automatically detect input voltage.

John

After several years of faithful service, I finally sold my Lincoln 350MP welder. I wanted something smaller and lightweight to use in my shop and the Multimatic 255 knocked it out of the park in many areas including ones I had not expected. Firstly, it comes in a smaller package, it should because it is inverter based as opposed to my Lincoln's brute transformer. This also translates to less weight as I shed over 100lbs. to lug around. So, lighter weight, nearly the same output, more features and a smaller packageâ€¦ I'm in, oh waitâ€¦ did I mention it pulses too! Then, there is the user interface. This is the iPhone of welders as far as I am concerned as it is well thought out, user friendly and very easy to read. I used to have to keep a log of my weld settings for future reference but now with the synergic "Auto-Set" not only does it have all the settings, it includes the gas mixture combinations as well. All of this is a real time saver when you are constantly changing processes on the run and not having to constantly look up settings for something you welded three months ago. The arc is what you would expect from a quality inverter based welder and it is a delight to weld with. Machine quality and accessories are of excellent quality that you would expect from a major manufacturer like Miller. The only two things I would have liked to see is a system to hang the MIG torch and work clamp instead of wrapping around the machine's handle, and a 110v outlet would have been awesome too. These are things I can fix myself to suit me better and aren't deal breakers. Lastly don't let the 255 naming convention fool you, as it did me, this machine will allow you to go to 350 amps, albeit for a short time, for those rare times you need more welding power. Other manufacturers sometimes severely limit output especially on single-phase. Duty cycles are very respectable also. The Multimatic 255 will exceed your expectations and won't disappoint!

If it had A/C Tig it would be perfect! I am the instructor at a private welding school in Miami. We recently got two of these welding machines. This welding machine is the answer for the light industrial and serious home fabricators. Who want or need a all in one welder. I have used it in every mode that is has available and it has given better than average performance every time when used within its limits. Personally I have Tig welded 3/8" steel plate in its various modes and am very pleased to see the scratch start Tig mode available. The guys who really do the work will appreciate that. When used as a Stick welder it is one of the better inverter type welders that I have used. I ran 6010 and 7018 1/8" rods with no problems and good performance. It's still not like burning rods with a straight DC engine drive but their getting closer. When used as a MIG welder with steel it welded 3/8" plate in one pass. The same results were experienced with Intershield/Flux Core wire in .045. We don't have the push pull Mig gun yet so I was only able to Mig Aluminum with the A30 spool gun. Using the spool gun I welded 3/8" aluminum plate with no problems. The fact it handles a full size roll of wire is a great feature. Another feature I really like about this welder is it's ability to work with almost any voltage available. My only complaints are that it doesn't have A/C Tig and the provided Tig torch and MIG gun are adequate but not as heavy duty as the machine. Overall I am very pleased with this welder and wouldn't hesitate to recommend it to anyone needing a compact multi process machine.

Most versatile, with the exception of 110. New to welding. Happy to learn and grow into this device that offers MIG, Flux, and TIG. I did NOT receive the additional wire feeder sizes and had to purchase the 220 male adapter separately. The male adapter should have probably been included just as it is on the Millermatic 255. Again I'm new to this, maybe not adding these things make sense somehow. Adding them, would have been 5 STAR.
