Millermatic 140 VS. Millermatic 211

admin

I have a MM 140 W/O autoset, 120 volt only machine. I know the MM 211 is a 120/240 volt machine. My question being, isn't the 211 only about the same thing weld output wise as the 140 when it is on 120 volt power source? I would tend to think so. The 211 would be about the same as a 140 when run on the lower voltage like the 140 uses. Anybody know for sure, or does the 211 some how weld better on 120 volts than the 140 does with the same input power?  This is something I have been wondering about for a few years, since the 211 came out with the MVP. At the time I bought my MM 140, the 211 was a 240 volt only machine and I was wanting a MIG that would work on 120 volt. If the 211 had been available with the MVP at that time I would have gotten one instead of the 140. I would like to upgrade to the 211, now that it comes with the MVP. I think the 140 would be about equal to the 211 on the same 120 volt power source. Anybody have a definite answer to this question?
Reply:At MIG voltages, 140 amps is about all you are going to get out of a 120 volt 20 amp household circuit. With that said, I would have to say yes, the 211 or any welder that can run on either would be limited to about 140 amps when running on 120 volt power.Sent from my SAMSUNG-SGH-I497 using TapatalkGravelThe difference between theory and practice is that in theory there is no difference.
Reply:Bisteneau,I originally bought a Millermatic 140 and after about 2 years I sold it and bought a Millermatic 211. That said, I would have to say on 110v, it is basically the same machine - same size, same parts, same good performance but not better. Then you have the option to run on 220v and that is MUCH better. As a hobbiest, my old 140 would do almost everything I have done with the 211. I don't know anything I've welded bigger than 3/16", BUT "you can't use amps you don't buy" (SundownIII). If you don't really need the 220v or don't have a 220v outlet, it would not pay you to upgrade to the 211 for better 110v performance.Burt _____________________Miller Syncrowave 250Millermatic 211Miller 375 Plasma Cutter Hobart Handler 12010FtDrillBit.com
Reply:I new to the mig stuff but looking at the 140, it has the wire feed speed listed 15 - 390 IPM 90 A, 18 VDC at 20% Duty Cycle                                                    the 211,      ''                   ''             ''     60- 540 IPM  90 A at 20 VDC, 20% Duty CycleI don't know how much difference it makes. Guess you may have better control with the 140 on light gauge material.I used my 211 on both light and some 1/4'' and it runs fine. Never tried the machine on 120 volts.I was kind of thinking on getting a 140 for .024 wire for a livestock trailer job I might do and leaving the 211 setup with .030.Last edited by BD1; 01-20-2014 at 02:57 PM.
Reply:BD1, I have a HH 140 that I use with .024 wire, and it works great with light metal. And I run .030 in my 211, this set up works great for me. I could have sold the 140 after I got my 211 but you know how that works, I would have needed the 140 with in a week. I did get a MM252 in March of 2013 and I run .035 wire in it but is sits 90% of the time.

Reply:Good analogy, Tim. The more I weld, the more I equate it to flying; fixed-wing yes but more so a helo. Touch, speed, amps, wire speed. And I'd imagine it's that way for alot of people. Equate what you're trying to learn to something you know and it seems to come alot easier. Can't wait to start practicing TIG. At least my feet will have something to do.
