I'm getting too much drop in power running my welder from a 30' extension cord to do the final welding on my frame. It worked OK to do all my tacking, but I noticed that the welder doesn't "sing" like it should and I'm concerned about not getting enough penitration running it this way.
There is a 220 outlet out back which a former owner installed to run a hot tub, but I think it's a 50 amp outlet... all my other outlets are 30 amp which have two hots and a ground. This outlet out back has an extra slot for a prong which I assume is a neutral... So, when I convert this outlet over to match all my other 30 amp outlets, what do I do with this extra wire? Cap it off or does it need to go into the mix somewhere?
Just for some clarification... This outlet has three vertical slots and one round hole.. I assume the round hole is a ground and the upper most vertical slot is a neutral and the two outer slots are the hots.
On the other hand... all my other outlets have two slanted vertical slots and a "L" shaped ground hole...
