A potentiometer is a voltage divider. I think you want to increase the resistance of the pot.
The wiper will be used to pick off a voltage that is typically used to bias the control circuit.
Normally, you would have maximum voltage at one end of the pot and zero at the other end,
but if the potentiometer has additional resistors in its series circuit, then the pot will be tuned
to adjust voltages within the design of the circuit, as each resistor drops a predetermined
amount of voltage based on the current that flows through the circuit.
I had a similar problem with my welding helmet. I bought some Swiss adjustable shade optics
in the bargain bin at my local welding supplier for $20 (but the control pot was missing.)
I installed a 90 Megohm pot to make the circuit work correctly.
Once the optics were working, I glued them into my existing helmet with silicone adhesive.
As soon as my 50K linear pots arrive from eBay, I will be making a finger tip torch control
for my Everlast PowerPro205. I've got a few designs in my head but they need testing.
I don't plan on investing much money into this project, its just for fun.
