Tig welder 3ph to 1ph

[Smyrk]

Hi been looking at a Miller Syncrowave AC/DC Tig 175p That is second hand. Because its cheaper and and industrial unit over the r-techs and tec arcs. But its 3 phase.
Might only have single phase tho when I move buildings. I read somewhere that some machines can be changed onto either?
Can this be done on that machine?

you would need to check the manual for the machine.

Owners manuals are here... http://www.millerwelds.com/service/ownersmanuals.php?model unless i missed it a 175p isn't listed by name so you'd need the serial #. If you can't get the serial # then the data plate should at least narrow things down some 1~ equals single phase, 3~ or three squigly lines stacked on top of each other = 3 phase. The input voltage range will also be on it along with input current for various outputs

Most (not all!) of the 'big beasts' are multivoltage single phase i.e. they can be fed using two phases of a 3 phase supply to 'bump up' the supply voltage and make them less greedy for amperage. Based on the generic owners manual for a 180 expect it to want a 40 - 50A supply if it's happy on 230V
