I have just purchaced a powcon 300st welder of ebay. It was not wired for220V but 575 3phase. From the google searches I did I thought it could be converted to 220 following Ian M's instructions. Alas when i opend the unit to make the conversion I couldn't find the 4 studs with busses to make the conversion. Am I screwed? I am trying to contact arccon and arc products but i am hoping for some info via the group wisdom. I have done google searches but without much luck.
Thanks in advance.
