Abstract: A resistance welding pinch protection system for use with a resistance welder, comprising a sensor array adapted to be secured around the base of a positive electrode of the resistance welder, the sensor array including a plurality of proximity sensors positioned along a perimeter of the sensor array, the plurality of proximity sensors defining an electrode operation field around the positive electrode, an input/output interface to be operatively connected to the resistance welder, and at least one processor in communication with the plurality of proximity sensors and the input/output interface, wherein in use, during the lowering of the positive electrode, the at least one processor interrupts the control signal to the resistance welding controller in order to stop the welding sequence, raising the positive electrode in response to the detection of an obstacle within the electrode operation field.
