Hi Bob, We are in the welding industry and make tig foot control pedals for a lot of tig machines, but I am not yet familiar with that particular model. If you have the specs on the potentiometer value, wiring, and connector needed, we could look into making one for you. Our stock models are listed at www.ssccontrols.com. Thanks, Brent

These old guys used a ceramic fixed resistor with a sliding contact, not a potentiometer. You should have two large receptacles for the control, a 4 blade and a 3 blade twist lock, I believe. We have some of the foot controls as well as the replacement elements. Thanks, Larry
