Thread: Powerarc 140STi

    Default Powerarc 140STi

    need advice on where to get a replacement capacitor for my powerarc 140STi -- it is marked as a L222 5070 apparently 2000 volt capacitor -- it popped when using it on a field generator which we think must have surged.

    the untrained eye says it is 2 micro farad 2000 volt foil capacitor.

    I need it to get my welder back and working for spring welding at the farm

    Can anyone provide advice svp

    If it is on the board, the whole board should be replaced. The unit should still be under warranty IF it was run on a generator rated for clean power output. If not, well, it will still need a board, even if the warranty is voided or you may have some cascade failures later.
