Subject: Re: [Homebrew_PCBs] Use for microwave oven ?

Obviously, you have to rewind the secondary.

Yea pretty much everything would be much easier to just go to harbor freight and buy, including PCBs. So what are you doing here then?

A microwave oven transformer puts out lethal voltage which can kill you. Most transformers are around 2000 volts at 500 ma  it only takes 100 ma to kill you. The capacitor acts as a voltage doubler to get it up to 4000 volts on the magnetron . cap charges through the diode,then when the ac power reverses that voltage adds to the transformer for 4000 volts

Spot welders use low voltage at very high current.  Would be much easier to just go to harbor freight and buy one.
