I just got finished a little bit ago replacing the shorted diodes , and the PF is working just fine again . Cause of the diode failure is still a question , may or may not have been an incompatibility between the welder and the PF unit . I suspect that because the two items were powered by different breakers there is a possibility that the diodes were subjected to 220 volts , which could have done this . Point is moot now though , and now I need to decide whether to re-purpose the old one or put it back for a spare . I don't plan any undo-able changes , so I may end up being able to do both !
