Miller 251 millermatic can it be run at 208v?

admin

I've got an almost brand new MillerMatic 251 mig welder and it has run on 240v 1ph perfectly. I am on the road a lot so it barely gets used except to hold my Miller Tig welder. I am looking into a new shop that was electrified by the owner for 208v 3ph 400 amp power. Before I commit to this shop I want to make sure most of my equipment will work. Will the Miller listed above switch over to 208 1ph or 3ph? I cannot find the manual to properly know and I am not an electrician even though I play one on tv.Thanks,JoeEnjoying life since I was born.This is where I would brag of equipment list -not.This where I would list my classic cars -notThis is where I would list my boats- notThank you for time on this board. I appreciate the help.

Hop over to the Miller site and download a manual from the "Resources" tab link for your 251....or pop the side of the welder and look at the area where the differing voltage jumpers is located as I seem to remember there being a voltage listing for the various options available.Lincoln PrecisionTig 275Miller 251Miller DialArc 250Bridgeport millHossfeld bender & diesLogan shaperJet 14 X 40 latheSouth Bend 9" 'C'Hypertherm 900Ellis 3000 band saw21"Royersford ExcelsiorTwo shops, still too many tools.
Reply:208 is the single phase voltage of a 480 WYE system and yes it will work for you Miller 251 the rule of thumb is you allowed 10% for under or over voltage.
