I have acquired FOR FREE a working L-Tec 304i tig welder. They thought it was burned out. The dumbies just let the coolent filter clog up and the tourch burned up!!!
MY PROBLEM IS- it is a 460V 3 ph unit.

How do I make a Rotory Phase Converter to change 220V 1 ph to what I need? I need at least 9.4 KVA.
