Shrink Tunnel Potentiometer / Knob
Potentiometer / Knob
The potentiometer controls the speed of the conveyor / motor by applying resistance to the incoming voltage before directing it to the motor. If the potentiometer is turned down, the motor will move slower. If it is turned up, there will be no resistance applied and the motor / conveyor will run at full speed. If your shrink tunnel speed is not functioning, it's time to replace your shrink tunnel's potentiometer (speed controller)!
