I just bought a 250v 50a receptacle to match my 220v welder plug. It only has three prongs.
The one connection is colored green, that is the easy one, ground.
What about the other two?
My guess is that the other two are both hot (red and black) and it doesn't matter which prong gets red or which gets black, right?
I guess it does not use a neutral (white)?

Does anyone know for sure? I don't what to blow up my welder, or myself.:mad2:

Yep, no matter which sides you hook the 110 feeds. Ground wire to green, either/or red/black to lines.

So, I'm right that it doesn't use a return (neutral)?

White or neutral not used, only need red+black both side's of the line and the ground wire green.

No neutral...just ground for safety, and will work without the ground. 220 stuff works by each 110 line working against another as opposing forces. Not sure of the dynamics...it just works! LOL

Great, Thanks guys. That is what I was thinking. I never feel that confident with 220v stuff, so I wanted to double check. :D:D:thumbs::thumbs:
