20amps at 12volts, What to do with it?
From taking down the halogen lights in the kitchen I'm left with a 250W transformer that outputs 12V, which I somehow took around 20amps to be, that's just using the first calculator I found...
I was wondering what to do with it, it's got a couple of projects to be attacked with, kind of scary evil ones involving high amperages through unsuspecting materials...
However, could I spot weld with it, I mean really thin pieces of metal, not to mention what else could I do with it. It's a well made transformer that doesn't overheat easily, has a nice tough casing and handy mounting points...
So I kept it in the, I'll do something with that spot...

Nice thing is, even if you don't use it right away, it will be great for powering alot of low voltage, high torque motors, heaters, fast battery chargers, and a bunch of other things I can't think of at this moment. (could also test your very own AC inverter design!)

Yeah but would'nt you want a lower current power supply for that so in case any components fail, they dont shoot of the PCB like miniature rockets... :)
Well sure, but that can be accomplished with secondary circuitry. the supply is the crucial source... Without that, ain't nothin possible.

Recommendation - Use the transformer as a supply for a switch-mode topology circuit (perhaps half-bridge, if you think you're up-to-it) and drive a self-made ferrite transformer for (if you want to weld) 2V @ ~125A, or, make a step-up transformer for some ridiculously-high voltage AC/DC experiments, like lifters or voltage multiplier cascades.
