Been a while but lately my interests have expanded to higher powered and tuning circuits. I wanted to build my own arc welder using a couple of old microwave transformers. I know it can be done and I have the materials to build and control output power but would it be feasible to include DC output as well, pulsed I'm sure. I have several 48v .38a adapters but I'm not sure what circuit would allow operation, if at all. I can go the 120vac in but I understand DC has its merits as well/safety. Any ideas or am I barking up a fallen tree?
