Whoops, i was wrong about the plug for the newer home stove, its four prong and not three, guess I never completely took it out before, only did some 110 mig welding since the big move. Three straight, one roundish on top ground. And trying to use my meter is a little tough, wasn't able to get total voltage. This will take some research, and the old extension cord connectors are obsolete, but the extension cord is twelve gauge, I thought it was ten, so its good for 115volt projects at 25 ft anyway, like my air compressor(25ft only at twelve gauge, same as my lincoln mig sp100 I've had for twenty years)
