Hey guys, Going to get the MM211 on Monday and just trying to make sure I get the electrical end set up and ready to go before I get it.I have a 60 gallon air compressor that I run on a 2 pole 20 amp. I was thinking I would just use this for the 211, but after doing a little research, I dont think a 20 amp would be enough, correct? I would think I need at least a 30? Should I just swap out ithe 20 for a 30? My compressor is only rated 15a though, so I feel like that might be too much....thats why I went 20 in the first place.What do you guys think? Id like to get this done tomorrow (today now).Any suggestions would be helpful.BTW, sorry if this doesnt go in this section....
Reply:Millers manual lists the MM211 as needing 24.3 amps at rated output on 230v. A 20 amp breaker will allow you to use almost all the power of that machine. They suggest using a 25 amp time delay fuse if you use fuses, or a 30 amp breaker would work. Using a smaller breaker means that these's a chance you will trip the breaker if you set the machine to high and try to weld. No big deal, reset the breaker, turn down the output on the machine and make yourself a note at what settings the machine tripped so you stay below that in the future. If you find you need to turn up the machine above where it constantly wants to trip, then think about getting the wireing upgraded to handle the higher draw load.http://www.millerwelds.com/om/o239988j_mil.pdfRemember you can't just change the breaker to a larger one unless the wire is rated to take the load. The breaker is there to protect the wires in the wall, not the machine..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear.

Reply:The 20A circuit should be OK if you're not pushing the duty cycle of the machine, but if you try to weld while the compressor is running, the breaker will pop in short order. A separate circuit for the welder would be best, or a 50A circuit for both if you only have room for 1 breaker.Also you will need a 6-50R outlet for the welder to plug into.JohnA few weldersA lot of hammersA whole lot of C-clamps
Reply:Could just run a 30 amp breaker with 10 guage wire dedicated to the 211 and you'll never have to worry about anything. You shouldn't switch out the 20A beaker for a 30A, especially if you don't know what guage the wire is.Millermatic 211 Lincoln Idealarc 250-250, ~500lb water cooled tig
