Could you weld with an induction cooker? Answered
Having seen the microwave transformer welding kit and similar projects I started wondering about this one... Induction cookers are basically one side of a transformer and usually just dissipate current in to the pot to heat up the pot. But they've a high number of coils and I've seen them rated at 3000 watts, so if you made a coil that was a few turns of thick wire to be the other side of the transformer you'd possibly be able to have a huge current low voltage supply similar to the microwave oven welder. I imagine there'd be safety devices that may need disabled but the idea of your oven being a welder seems cool to me, especially if someone had a need to weld often and their kitchen was through to their garage.
