Spot welder

[Frank S]

I don't see anything wrong with it. I like the fact you used a much larger transformer to make your spot welder. The ones made with even a large microwave transformer are dismal in power. I even made one several years ago to determine if everyone's claims of the high amperage output was anywhere near real. It takes a lot of core weight to create a large enough magnetic field to achieve enough amps to do any good.
