hobart 450 megaflex rvs

has anyone heard of these they are three phase mig dc tig and stick older transformer i think
had a chance to buy one for $150
i did not buy it as i was not sure if it could be converted to single phase
bought the thermal arc dual digital wire feeder it came with to run on my miller cp300
the hobart was a very nice welder and the three functions were rare for the vintage
was just wondering if anyone knew anything about these
thanks

3phase usually 480 volt machine built by Hobart Bros in the time when everybody was trying to build a multiprocess machine

No, regardless of what the space cadets of the Church of Kemp Haas claim, it can't convert to single phase unless you want crap arc quality.

The only good multiprocess machine of that era I ever ran was an Airco DipStick, and it suffered in the mechanics of the wire drive.
Airco built from a sliding core transformer with a dam heavy core. Multitap power units couldn't match the arc.

Good machines but always three phase and as Virgil stated "multiprocess". Very good in the time when both stick and wire were both used in the same factory.

There was also the drawback side of multiprocess machines..
Just like living room console HiFi/radio/TV when anything went out you were totally screwed.
