All I'm saying is double check, 50 amps is not a lot when you turn on lights, welder, radio, fan, and then the air compressor leaks down and kicks on.
For example, a Millermatic 210 MIG, representative of a couple of the welders referenced in previous posts (and a dang good choice for a MIG machine, by the way)will pull 31.2 amps out of the wall according to the owners manual (page 13) at
http://www.millerwelds.com/om/o1325q_mil.pdf Yes, that is when the welder is turned all the way up, but I wouldn't put it on a 20 amp breaker in *my* shop.
Yes, a Miller 140 amp 110 calls for a 20 amp 110 breaker,
http://www.millerwelds.com/om/o225311a_mil.pdf but if you buy a cheap welder they are not as efficient. I had an old crappy flux core 80 amp that called for 30 amp breaker.
Again, I am suggesting original poster ought to add up the amps and read the manual before he plugs things in and pulls the trigger.
