Abstract
a. Source de courant pour la soudure à l'arc, et notamment pour la soudure à l'arc sous gaz inerte du tungstène. b. Source de courant caractérisée en ce que le transformateur de courant triphasé comporte des enroulements primaires de préférence branchés en triangle et des enroulements secondaires de préférence branchés en étoile, chaque enroulement secondaire étant disposé en série avec un ensemble de deux redresseurs susceptibles d'être commandés branchés en antiparallèle qui sont en liaison avec une pièce d'oeuvre, le point médian des enroulements secondaires étant raccordé à une électrode de soudure. c. L'invention s'applique notamment à la soudure à l'arc sous gaz inerte du tungstene.
