Hi All. I need some help with my Migatronic BDH 320. There is a Err P-2 code failure when i turn it on, and it wont weld. Fund the codes on a pdf and its a inverter fail, but couldn't find the inverter diagram ?. Well i dismounted the welder, cleaned every thing up good and looked for cracks and burns, found non. But still no good. Any suggestions on what to look for, maybe where to measure ? Regards Simon Denmark.
