stripping out old UPS (uninterruptables)- find huge diodes? SCR's?rectifier bridges? doorknob capacitors? telsa primary
I'm contemplating building a high frequency "arc stabilizer" box for a
welder (which I understand uses nearly all same components as a tesla primary circuit). I'm a talented fabricator, soldering iron guy, etc. and a superb DISmantler :-) I have a "near endless" supply of UPS (uninterruptable power supplies) of various types and sizes (up to and including "HUGE monsters") I could strip for their component parts. I'm -wondering- if they'd provide me any of the parts I'd need, like: rectifier bridges? doorknob capacitors? huge diodes (with 'braid pigtails' and studs?) SCR's? transformers? other than the huge batteries (which I'd leave behind) I have no -clue- what's inside 'em...alternately, if they, generally, have no components I could 'use' for my project, what other component parts would they ordinarily contain that 'other guys' could use? thanks for tips and clues :-) box |

Take a look inside, and see!
