i just aquired this , was wired for single 220, checked wiring and it was all shorted and burnt, looks like the ground stud had burnt out a while back and they re wired to frame , currently has red and black as hot and white and green as neutral, i have three phase but is this a three phase machine, i dont see a place on rear to add line 3 just 1&2, if i remember right some old areas used to have 440 single phase, the 3 options for wiring are 208,220 and 440, guess i will have to re wire and test, just wondering if anyone has been down this road before or any ideas appreciated , i attached some useful pics and lit, thanks in advancewelder 004.jpgwelder 003.jpgwelder 002.jpgwelder 001.jpg
