Abstract

PURPOSE: To enable welding operation continuously, by measuring the temperature of the electric power transducer and automatically controlling the quiescent time depending on whether the temperature exceeds the set temperature or drops below this temperature.
CONSTITUTION: The work to be welded of which welding conditions are predetermined is set in a specified position, and a start command is inputted into a start command part 20 from the welding line. Then, fulfillment of starting conditions is confirmed, and it is judged whether the temperature of thyristor stack is in the normal operating range or not by a temperature detecting part 16. If within the range, the welding set conditions are read out, and welding is performed, thereafter repeating this procedure. If the rate of use is raised due to change of welding conditions or if the thyristor stack temperature is raised by the temperature rise of cooling water to exceed said range, the sum of the set point and a certain additional value is determined as a new quiescent time in a quiescent time command part 19, and welding is performed by N times. Then, measuring the temperature again, if the temperature is not lowered yet, a certain value is added again, and welding is performed by N times, continuing until settling in said range, then the quiescent time is returned to the original set time.
