Hello, I have a lincoln 140c MIG welder that draws 27 amps max. Could I use a 4500 watt generator with a 23 amp outlet? If I dont use high voltage I can draw less than 23 amps. Would the generator be able to supply enough constant power?
Reply:Should be possible to use, so long as you are not using max output of the welder. But then you are not going to be welding much with having to run the 140 amp MIG  below max  power. As long as you are only doing light gage material it may do OK.
Reply:As long as the generator can keep a constant 23 amps thats all I need.
Reply:23 amp outlet?usually 15amp, 20amp and 30amp 120v receptacles on gensets. If the 4500watt genset is a 120v generator ( I know Champion makes one for the Rv market with a TT-30 receptacle on it) then you are good.If it is a 120v/240v generator you only have half of the rated power since it is a Split Phase power source. half of the receptacles get 2250watts/120v 18 amps. That is also usually surge power as generators are sold/marketed with a Surge Power rating and a continuous power rating, which is lower. Could be 1000watts less power. A 4500 genset could be rated 3500watts- again this wattage will be split in half for 120v loads.If you already have the generator give it a try. If you are thinking about buying one post up the specs/model/make so we can see exactly what power the genet can provide.Ed Conleyhttp://www.screamingbroccoli.com/MM252MM211 (Sold)Passport Plus & Spool gunLincoln SP135 Plus- (Gone to a good home)Klutch 120v Plasma cutterSO 2020 benderBeer in the fridge
