Question on 300 amp class AC/DC TIG machines and single phase

[performance]

As I mentioned, most all I have come across don't mind either if it can operate on 208, including our welders.

Thanks all for the info. As far as I know the electrical service on my small town (Rockville, MN) is OLD. I don't know if that means it's delta or wye, or 208, 220, 460. I do know that when I put a volt meter across each leg of my 30 Amp outlet, I get about 123 volts per leg. I will be in contact with the local utility company in the near future, as it looks like a Bridgeport mill (complete with prototrak cnc capability) may be in my near future. But one question remains unanswered. Does Everlast have plans to offer either of the 315 Amp TIG welders (or an altogether new 300 Amp model) with single-phase input, as an option in the near future? This won't change my mind as far as getting my 250EXT, just wondering.

On some of the older cnc mills, the only thing 3-phase is the motor. Very easy and affordable to convert to single phase with a VFD.

I would say that is wye 120 volts to ground 208 across phases. Most power companies will build what you want its all about the transformers and way they are wired as long as there is three phase primary in area.
