i tried google and no luck finding how to build a turntable for welding.. im considering doing that.. and if i use a rotary table (with variable power supply) thats normally used for mill or stuff liket hat.. was wondering if its possible to have it stop after one full revolution... stop the welding and turning the table.. or just stop the welding thats all would be perfect.. any suggestion on how? i was thinkin of a normal switch or something with a thing sticking out to turn it on and off.. anyone got better idea?
