Give the machine needs doesn't need a huge amount of current you
can make your own 3-phase power from joining 3-groups in your
home/workplace. You'llbe limited by the max current the fuses of
that group can handle. And you'll need to find out the live
wires of those groups. Check a handbook on the subject.
