(in my humble opinion a piece of metal falling off the inside when it is sitting on the ground untouched is faulty)
I have had two of these welders of which I still have one left. Both developed that same problem that you are describing .The heat selector(or amperage) had developed corrosion on the contacts . All I did was rotate the switch back and forth briskly and got it to work for the work at hand. I cleaned the contacts at a later date by pulling the knob off (has a set screw)and unscrewing the flat nut holding the switch to the panel and pulling the switch out of the panel .I then used a small wire brush to clean the contacts. Both are still working fine.
If oldschoolrods can't find a diagram for it ,post back or send me a PM and I'll pull mine apart and take a picture of the diagram and post it.Mine no longer is set up like it came from the factory. I gutted it and use it as a wire feed for my alternator welder that I built. The control board went bad and the replacement was 107 bucks..........so I said nuts to that and built my own controller for about 12 bucks in Radio Shack parts.
Good Luck !
