Title (EN) AN AUTOMATIC DARKENING FILTER ASSEMBLY FOR A WELDING PROTECTOR AND A WELDING PROTECTOR
(FR) ENSEMBLE DE FILTRE ASSOMBRISSANT AUTOMATIQUE POUR UN PROTECTEUR DE SOUDAGE ET PROTECTEUR DE SOUDAGE
Abstract:
(EN) An automatic darkening filter assembly for a welding protector and a welding protector that includes the automatic darkening filter assembly. The automatic darkening filter assembly has a housing that forms an opening in which a switchable light filter is arranged. The switchable light filter is retained by a first and a second resilient gasket that are arranged on opposite sides of the switchable light filter and which each extend circumferentially adjacent a periphery of the switchable light filter. The invention helps maximizing the robustness of the welding protector and facilitates assembly.
(FR) La présente invention concerne un ensemble de filtre assombrissant automatique pour un protecteur de soudage et un protecteur de soudage qui comprend l’ensemble de filtre assombrissant automatique. L’ensemble de filtre assombrissant automatique comporte un boîtier qui forme une ouverture dans laquelle un filtre optique commutable est agencé. Le filtre optique commutable est retenu par un premier et un deuxième joint d’étanchéité élastique qui sont agencés sur des côtés opposés du filtre optique commutable et qui s’étendent chacun de façon circonférentielle à proximité d’une périphérie du filtre optique commutable. L’invention contribue à maximiser la robustesse du protecteur de soudage et facilite l’assemblage.
