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
