[Gippetto]

I thank all who replied with a suggestion for my Miller problem. The Miller Welding tech support guy suggested looking for shorts in the spool area then removing the torch brass plug from the split clamp connector and scoth-briting male and female components.
I lucked out because that corrected the problem. The brass looked pristine but I polished its inside and outside diameters and got results. Luck for me, the next suggestion was replacing the entire gun. He said the braided copper sleeve that connects the gun to the machine was screwed from pulling the machine around by its hose. Sort of like an old girlfriend. That wasn't the case.
