Abstract
Un aparato de control para la soldadura por resistencia, que incluye a) medios de interrupción destinados a permitir que circule la coriente de soldadura; b) medios para vigilar la resistencia de la soldadura de la pieza de trabajo o una función relacionada con la misma, c) medios para descubrir cuando la velocidad de cambio de la resistencia, o la función de la misma, ha alcanzado un valor predeterminado, d) medios para calcular el tiempo adicional (Tt) durante el cual la corriente de soldadura puede circular, definido por la identidad Tt=tp x A+ B , donde Tp es el tiempo que el régimen de cambio necesita para alcanzar el valor predeterminado, Tt>= Tp, y A y B son constantes, y e) medios para abrir los medios interruptores cuando ha expirado el tiempo (Tp+Tt)
