My experience has been that a transformer machine will work well on a
rotary phase convertor, up to the limit of the convertor's ability to
produce the third phase.

Older machines without solid state output control (Miller migs with the
three big coild with brushes that slide on them) should work well on
single phase, as another poster recommended it'll be important to
isolate the line that feeds the fan, etc.
