Title (EN) SYSTEMS, METHODS, AND APPARATUS TO PREHEAT WELDING WIRE
(FR) SYSTÈMES, PROCÉDÉS ET APPAREIL POUR PRÉCHAUFFER UN FIL DE SOUDAGE
Abstract:
(EN) An example welding-type system includes: a welding-type power source configured to provide welding-type current to a welding-type circuit, the welding-type circuit comprising a welding-type electrode and a first contact tip of a welding torch; an electrode preheating circuit configured to provide preheating current through a first portion of the welding-type electrode via a second contact tip of the welding torch; a switching circuit configured to control a current flow between the welding-type power source and the first contact tip; and a preheat control circuit configured to control the switching circuit to: selectively direct current from the welding-type power source to the second contact tip; and selectively divert current from the electrode preheating circuit to the first contact tip.
(FR) Un exemple de système de type soudage comprend : une source d'alimentation de type soudage conçue pour fournir une puissance de type soudage à un circuit de type soudage, le circuit de type soudage comprenant une électrode de type soudage et un premier tube-contact d'une tête de soudage; un circuit de préchauffage d'électrode conçu pour fournir un courant de préchauffage dans une première partie de l'électrode de type soudage par l'intermédiaire d'un second tube-contact de la tête de soudage; un circuit de commutation conçu pour commander un flux de courant entre une source d'alimentation de type soudage et le premier tube-contact; et un circuit de commande de préchauffage conçu pour commander le circuit de commutation pour : sélectivement diriger le courant de la source d'alimentation type soudage vers le second tube-contact; et sélectivement dévier le courant du circuit de préchauffage d'électrode vers le premier tube-contact.
