Abstract
A control system for parallel gap welders typically employed to weld contacts to solar cells or wires to integrated circuit chips is disclosed. The system monitors the temperature generated by the welder at the work pieces. The system automatically terminates the weld operation should the weld temperature reach a maximum predetermined temperature, thereby preventing overheating the weld joint and adjacent parts. Alternatively, if the weld temperature does not reach a minimum predetermined temperature the system automatically signals the weld operator that the joint must be rewelded to avoid an incomplete or cold weld. A quality weld can therefore be repeated.
