I have access to a lot of metal working equipment that works on 550 ac volts

my house. Is there a way to convert 220 volts ac 1 phase to 550 volts ac
3phase.

Two ways: use a single phase transformer to step 220 up to 550 and make a 550VAC
phase converter, or convert 220 1ph to 220 3ph and then use a three phase
transformer to step up to 550 3 phase. Be sure you size your transformer large
enough. - GWE
