Abstract

Dispositif de régulation de la profondeur d'immersion d'une électrode, comprenant un équipement de saisie de la résistance instantanée et de sa variation, un équipement de régulation de la commande de l'électrode et des lignes de mesure du courant et de la tension de fusion, reliées à un diviseur. Le diviseur 28 est connecté de façon à délivrer un signal proportionnel à la conductance instantanée.
