Hello everybody. I'm looking for anybody able to help me finding a way to fix my welder. Bought it from marketplace but as a trusty person didn't check it. It appears that previous owner dropped it, and as a result cooling fan fell on rectifier causing short circuit. Now welder turns on but is constantly in overheated mode (led is on) and there's no action from the wire feeder or nothing. Changed burned fuse on pcb but with no luck. No visible frying marks on PCB. All diodes on rectifier seems intact. Has anybody dealt with similar issue before? Thank you and happy 2019 for everybody.
