Abstract

Perfeccionamientos en las fuentes de corriente de impulsos para la soldadura bajo gas inerte entre metales, las cuales comprenden un circuito para producir una parte de corriente de base de la corriente para soldar y un circuito para producir una parte de corriente de impulsos de la corriente para soldar, caracterizados porque en cada circuito se ha previsto un elemento (3, 5) de ajuste para influir sobre la parte de la corriente de base y la parte de corriente de impulsos de la corriente (Is) para soldar.
