I have spent hours trying to find information of this capacitor and have come up with nothing at all. I have nine of them that came out of a old stud welder. I have looked for a parts list for the welder also and was unable to find one. The welder was a,

The capacitors seemed to be in parallel. Any help would be greatly appreciated.
Thanks

the 6808 J could mean 68000uF if it's using the pico farads standard. if you could figure out the peak voltage for the part of the circuit they were in that'd probably give you some indication as to their voltage rating. if the 68000uF is correct, and since it's a welder, i imagine the voltage would be in the 25-50v area. if you could find the RC time constant that'd give you an idea of the capacitance.
