Abstract
Electric welding system having a governor control for regulating the speed of the electrode drive motor and for controlling the direction of motor rotation in response to voltage and current welding parameters such that during welding the motor is driven in a forward direction toward the workpiece and under the control of a weld speed potentiometer whereas during a short circuit condition and at termination of the welding operation the motor direction is reversed.
