When I want to use 220v (because I don't yet have a 220v 50a circuit) I plug the machine into the jumper I made for the dryer plug. Machine plug connects to the 6-50 receptacle, which connects to the dryer circuit.

When I want to use 110v I connect the machine plug to the 6-50 receptacle on the 110v jumper, and plug the other end into the wall. Everything is in-line, with nothing hanging loose or unused, as the term "pig tail" may lead you to believe.
I think the word jumper might help me explain.
Thanks for all the help everyone, I've got all this info compiled on a small piece of paper with numbers and plug/outlet pics..... Heading back to the store so we'll see how this goes.
I have a Nema 6-50 in my shop but I like the idea of the twist lock on the end of the welder so if I am using 110v with a long extension or whatever, it won't just "pull" out.
