Just read this fascinating thread. With regards to rewinding MOT's, I built a spot welder a while back using sheet copper for the winding with paper interleaving: https://www.instructables.com/id/Spot-Welder-from-a-microwave-oven-transformer-and-/. Wouldn't like to guess how useful the technique is for a stick welder though.
