ABSTRACT:
A foot control for a TIG welding machine utilizes a timing belt that is tensioned between a pedal and an enclosure. The timing belt meshes with a timing gear that is fixed to a rotatable shaft. Pivoting the pedal on the enclosure causes the timing belt to travel past and rotate the gear and shaft. A potentiometer on the shaft also rotates to control the power output of the welding machine. The belt is tensioned by a relatively weak spring in a manner that biases the pedal in one direction on the enclosure. A stronger spring biases the pedal in the opposite direction. The pedal is hinged to the enclosure by resilient tabs on the enclosure having bosses that engage holes in the pedal. The tab bosses can be depressed to disengage the pedal holes and enable the pedal to be removed from the enclosure. A heavy base joined to the enclosure has plates that lie alongside the enclosure tabs such that the tab bosses cannot be depressed out of engagement with the pedal holes when the base is joined to the enclosure.
