WELDING TORCH OSCILLATOR CONTROL SYSTEM ABSTRACT An oscillator control system for reciprocating a welding torch comprising a drive motor and an oscil- lator circuit for alternately varying the direction of rotation of the drive motor. The oscillator circuit includes DC reference means, means responsive to the rotation of the motor for providing an output signal which varies in DC potential from one polarity to the opposite polarity, means which responds to the differ- ence between the reference signal and varying DC signal and switching means which reverses the polarity of the reference signal when the difference signal reverses polarity.
