You don't have 2 phase power, this is a misconception. You have 2 lines which
together comprise single phase power.
High frequency is an arc starting method and isn't related to what metal you may
be welding. For aluminum, you need AC TIG and lots of current.
For getting pricing information, nothing beats ebay these days. Look at
completed auctions only. Or, you could try selling it on craigslist for a bit
more than you paid for it. If you get several calls right away then you know
your price is a bit low, and you could cancel the craigslist ad and then repost
it a few weeks later a bit higher. Might chap some guys' bacon, but it's legal.
Your goal should be to get out from under it without losing any money, thereby
getting a very important lesson for free, namely don't buy 3-phase welders
unless you have 3-phase power.
Good luck!

I realize this is the correct answer in 99% of the times it is brought up,
but since I live about 30 miles from one of the places you can still get
2-phase power wired up to your business:

Please log in for more thread options I think what I have on my property is two high lines of the three on the street.
From one of the high lines is a tap to a transformer that then provides 220 at
180 degrees. Single phase 220/240.
I suspect I could at great (but not as bad) expense install three transformers
and run an inverted V delta input and generate 66% eff output getting 3phase.
This was once a lumber mill site - and the four transformers are still here.
Two are used (by me) as line terminations at the end of the stub from the
main line on the highway. The other two are for the shop (first) and then house.
Oddly, I tap off the same high line on both transformers.
