Abstract

Appareil de soudure à l'arc à courant continu. Il comprend des électrodes de soudure qui sont alimentées par un courant pulsatoire continu depuis une source de courant alternatif, le courant provenant de ladite source de courant étant amené à travers un convertisseur de fréquence commandé qui accroît sensiblement la fréquence du courant alternatif, puis vers un transformateur et un redresseur pour obtenir le courant de soudure sous forme pulsatoire continue, un filtre de lissage pour lisser le courant pulsatoire du redresseur étant relié entre la sortie du redresseur et les électrodes de soudure.
