running a 3phase MIG welder on a rotary converter setup - doable?impractical? impossible?
moving OUT of my shop and back into my garage at home. shop has three
phase. I want to buy a used MIG, but lots of the ones I see are three phase. anybody here ever run their MIG (or any other three-phase welder, for that matter) on a "rotary converter setup"? would running a welder on a rotary converter setup be 'ill-advised'? I already have a rotary converter rated "max single motor three hp, max total hp 12 hp", but it's not clear to me how that relates to using it with a welder...or if it's even 'doable'? thanks in advance for educating me on this, guys :-) toolie == ps-replies by e-mail, if any, please remove the weirdstuff from my address before you click 'send' - thanks == |

Welders run fine on rotary converters. You have no motor startup
current to contend with as you would with a motor, and unless its one of the latest ones that's all electornic it will use just about any power you feed it, in fact you could just hook up a bank of caps to generate the third phase on the old ones and not even bother with a rotary generator.

I have been told (ot done so) that it will work on single phase just derate
the output. "john" wrote in message ... Welders run fine on rotary converters.

However..Im not buring anything bigger than .035 wire and the distance from the RPC and the welder is less than 20 feet. However..I can do a very nice spray transfer.
