I salvaged some actual powerfactor correction capacitors made by mallory.
They are 60uf, 480v rated and are about 3 times the size of a standard 440v 60uf motor run capacitor.
Not sure what to do with them. Had I found these before I bought the 80uf capacitors to put in my large arc welder I would just use twin 60s, since its hard to beat the pirce I paid for them, free.

I did some more work with my mig welding machine. I swapped out the internal component capacitors for a single externally mounted 40uf motor run capacitor. I found the 40uf reduced amp consumption a little better than 30uf. Total saved is about 2 amps. It wont save much on the power bill but it will make the welder more extension cord or generator friendly.
