i juust got outbid on some nice 4052 Stud Type Power Diodes
from ebay
where else (other than digikey) can i get some diodes that can handle 300 amps and 270 volts?
try to keep the prices down

Maybe try http://www.farnell.com for your diodes. I remember seeing in their cataloge diodes of in excess of at least 200A I think. Remember you can always paralell your diodes to add more current handeling capability.

Likely a TIG welder. The better ones have a pilot arc that is quite a high voltage, so you don't have to scratch your expensive tungston to start the arc.
As for the diodes, I have no idea.

i have seen a welding machine that has a spark gap that turns purple ..but have no idea
what it does..is it a pilot arc ? it should be a sustained high voltage but i still dont know what it does..Lincoln and Miller i now recall..

gee you tickled my interest about welding..i kind
of get occasionally when things get out of focus and the two wires get welded unintentionally and you have to reset the circuit breaker.. i think spot welding has some
advantage over plain soldering when your circuit is involved in high temp invironment.
i have a 1 kw 220v pri 32v secondary transformer working as a paper weight for the mean time ..u gave me an idea..thanks
