Abstract

Aparato soldador de arco de corriente continua caracterizado porque comprende electrodos soldadores que se alimentan con corriente continua pulsátil derivada de una fuente de corriente alterna, alimentándose la corriente de dicha fuente de corriente a través de un convertidor de frecuencia controlado que aumenta sustancialmente la frecuencia de la corriente alterna y después a un transformador y a un rectificador para obtener la corriente de soldadura en forma continua pulsátil, y en cuyo aparato se conecta un filtro para filtrar la corriente pulsátil procedente del rectificador entre la salida del rectificador y los electrodos soldadores.
