I planned on leaving the "L" prong out and using only the two flat Hot blades and the "U" Ground. Should be good, no?
You can do this, but it's not code...and you don't try to make the mistake of matching wire colors to do it. White and black are hots on the welder side. Red is left out of the way. Match black to black, and white to red.
