    SA 200 Rheostat Issues

    Hey all. So, my '76 SA 200 has a dead zone on the rheostat below 40 amps. It doesn't matter if I crank the range selector up to warp 10; I still can't strike an arc with the fine adjustment set in the lower 40 amps. The machine welds great in any gear with the fine tune set above 40. Any thoughts?

    .Rheostat has a break in the winding.Check Fair Radio for a new one .Ohm rating should be marked on the rheostat.You can see the break.

    Your join date looks a lot like March 2015. LOL!

    Regardless of your join date it sounds like you need a Ohmite 5090c rheostat, available from all the online vendors that cater to the SA200 crowd and also fleabay.
