Abstract

La présente invention vise à procurer un appareil de soudage apte à commuter des fils de soudage sans affecter de façon défavorable le fonctionnement. A cet effet, selon l'invention, dans la commutation d'un fil de soudage métal-gaz inerte (22), lors de l'utilisation, à un fil de soudage de brasage (20), le fil de soudage métal-gaz inerte (22) est coupé, la pointe du fil de soudage (22) s'étendant à partir d'un tube d'alimentation en fil de soudage (23) est ensuite incurvée de façon à empêcher le fil de soudage (22) d'être tiré dans le tube d'alimentation de fil de soudage (23), et le fil de soudage (22) restant dans un appareil de fourniture de fil de soudage (13) est extrait. Après cela, une broche d'alignement (28) est retirée, un boulon à ailes (30) est desserré, et un élément d'oscillation (16) est tourné dans le sens des aiguilles d'une montre autour d'un arbre (17). En résultat, un commutateur de limite (24) est mis hors service, et un commutateur de limite (25) est mis en service.
