Abstract

L'embout de contact pour le soudage de la présente invention, fabriqué dans une matière conductrice, est muni d'un passage destiné au fil utilisé pour le soudage à l'arc automatique ou semi-automatique. Cet embout permet de réduire les coûts d'exploitation grâce à une productivité accrue et une durée de vie plus longue. L'embout est constitué, d'une part d'un corps d'embout de contact (1) pour le soudage dont l'extrémité côté pointe présente un perçage fileté (4) dans l'axe du passage du fil (3), et d'autre part d'une pointe d'embout de contact (2) présentant une partie filetée (5) dans l'axe du passage du fil (3), ce qui permet de la visser de façon interchangeable dans le perçage fileté (4). La pointe de l'embout de contact (2), ou la pointe de l'embout de contact (2) ainsi que le corps de l'embout de contact pour le soudage (1) sont réalisés dans un matériau résistant à l'usure.
