I'm no longer trying to fix this Parkside PISG80A1 inverter stick welder because the cost of a brand new replacement coupled with the speed of Amazon next day delivery makes repair pointless. I still have a brain itch about what happened when it broke.
I was up a ladder welding a tractor door hinge when I noticed the grass had set on fire. In my haste coming down the ladder to pat out the flames I caught the cord & the welder fell on the floor. Then no power - turns out tripped breaker in the house.
Dismantled welder, found one obvious damage - a big fat square classic-looking bridge rectifier with quarter inch spade terminals, had one of it's flying leads off.
I'm used to bridge rectifiers using all four terminals but this one in this unit only has two lugs connected, 2 diagonally opposed. Not sure if they're the +/- terminals or the AC ones.
The one flying lead that had become disconnected, apparently by the fall, appeared to have momentarily brushed against one of the remaining 'unused' lugs evidenced by a burn mark on it.
Tried replacing the displaced lead, but on powerup it just blew the house breaker again.
I've ordered a replacement because I just thought, it's cheap enough not to go too far down the rabbit hole over.. but I'm puzzled why one would use a bridge rectifier like that (maybe I'm wrong and it just 'looks' like a bridge rectifier to me)
