Depends upon the power required and the type of equipment. Welders,
because they are a reactive load, aren't well-suited to phase
conversion. 3-phase motors, however, can be run on either static or
rotary converters. Usually, a rotary converter is just a static
converter with a 3-phase motor attached to it, along with a smaller
single-phase motor to get it started.
Try going here to get an overview of 3-phase conversion and some simple
schematics:
