I think that in *that* situation -- the welder is depending on the
current through the back loop to trigger the solenoid which brings the
ends of the blade into firm contact to make the weld. I've never
bothered to actually trace out the circuitry for the stand-alone blade
welder which I have, however.
My unit is pretty primitive. The motion that brings the blade ends together
is manual, a lever that is depressed. I'm mystified by this thing, DoN.
I have a pretty primitive blade welder too, but it welds hacksaw blades
just fine. Doubt we'll ever get to the bottom of Harold's, glad his blade
welder works!
