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.

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.

 

That's kinda what I figured on the output of the 2 units. The 211 is the same, Thanks for the reply from someone that has used both of these machines. I don't have a problem upgrading to the 240 V outlet to run the 211 if I need it. It's just at the time I bought the 140 I didn't have easy access to 240 where I needed it, WHEN I needed it. If need be, I can run the 211 off the Bobcat 225, but then anything more than what the 140 can handle, I can do with the 225 instead.
If I could sell the 140 and the adapter box for the spool gun, then I think I could sneak the new 211 past the ole' lady with out her noticing the change in machines since they LOOK almost the same. The spool gun I have will work with the 211 without the converter box. Anybody needing a MM 140 with the SGA 100 adapter for the spool gun? This machine has less than 40 Lbs. of wire through it total, spool gun and MIG gun since I have had it, 50 Lbs. max, but I doubt it.

 

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 Cycle
I 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.

 

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.

 

Yes, you can never have enough machines. I don't do a lot of mig but the 211 does a nice job no doubt. The 211 is my BIG mig, I'm a old time stickman myself. The 302 Trailblazer for mobile work and the CST 280 home/shop. Not to mention my old 180SD tig. Weldermike had a 180 too and it died. He then got the new 210 syncro. As soon as my 180 dies I'll do the same. It just keeps on going.

 

How much $?

 

I've been checking craig's list for months for a 135 or 140. In my area they are trying to get from $550.00 to $600.00. I got a price on a NEW 140 for $720.00. Here, http://chicago.craigslist.org/chc/for/4294867440.html

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.
