ABSTRACT:
A method and apparatus is provided for applying an electrical welding current between contacting members upon detecting a predetermined electrical resistance therebetween. Measurement current pulses are applied through the contacting members prior to the initiation of a weld current therethrough. Measurement voltage pulses, induced by the applied measurement current pulses, are compared against a reference voltage level. When the magnitude of the voltage pulses decreases to a value less than the reference voltage level, a weld signal is generated which causes the application of the weld current through the contacting members for a predetermined period of time.
