I recall reading on another forum where someone converted their CP-300 or 302 to run on single phase. By doing that, I don't believe you get full ratings as you would on 3 ph.

I have a older XMT version that is convertible to single phase. It's drawback is, it is de-rated at 250 amp output instead of 300 amp output. So far, I haven't had a need for that high of amperage out.

I do not know what the above machine is, but 230v 3ph is no problem and is what I prefer.

Default CP300 vs CP302-vs.CP200

Razor, the CP200 you have the photo ad of there sure looks like the same machine as the CP250..the controls are laid out the same on the front panel.The CP250 has adjustable taps on the input side of the transformer for 208/230/460V so you can match it to what power you have. My analysis is its a CV power supply for MIG welding only, as the photo has a wire feeder and rolls of aluminum filler closeby..the 'CP' stands for Constant Potential-if it comes with the feeder grab it at that price,or start at 250 cash and see it the seller will bite...do be aware it is a 3phase machine and will need mods to run on single phase 240V. You also may be into a lot of restoration work on that CP to get it back up to operating level..it may be repaired many times over(Donnie just get it working so we can finish the shift-)-IE: it might cause you enough hassle you wish you'd have bought a newer one

Thanks so much bunkclimber. I was not even aware there ever was a CP250. First time I've ever heard of one.

that CP300 on craigslist you posted the pic of is a good deal even if it has issues,the MIG gun on that feeder alone will cost you about $250 or better to replace..If its a Tweco or Bernard mig gun you can always get contact tips and wear parts..the feeder might be a bigger challenge..still a deal..sometimes ya gotta say WTF and go for it
