ABSTRACT:
A monitoring and control system for a resistance welding apparatus. The system monitors the quality of a weld as a weld is formed and terminates the welding current when a quality weld is completed. The monitoring function is performed by detecting a change in the instant welding current is extinguished at the end of half cycles of welding current in the secondary winding circuit of the welding transformer. The weld current is terminated when a detected charge in the instant current is extinguished relative to a reference equals a preprogrammed value which is indicative of an acceptable quality weld between welded parts.
