I have read about how to hook up my dryer to a 4 prong to make it match my 4 prong outlet and lucky for me, it sounds like you guys(gals)really know what you're talking about! I have a 30-120amp 230V mig welder that came out of the box with no male plug. It only has 3 wires though and my garage outlet,(wired in 2001 new construction) has a 4 prong outlet. I have replaced 110v light fixtures and added on extra outlets in my basement, but never messed with 220 before. I have to admit that it kind of scares me! :dead: I would love to hear from you! Thanks!
