my 220 welder circuit doesn't have a neutral, so i'll tie this to
ground. Sound good?

Supply neutral. It doesn't matter if the welder has a neutral or not,
just the supply side.

Maybe my wording is incorrect. I will plug this device into the welder
outlet. It has three wires, two hots and a ground. So, I will be using
the ground as a neutral. probably not code, but should work?
