Method and system for the accelerated reaction of the darkening of the optical element in a welding protection device

摘要

A system for an accelerated reaction of a darkening of an optical element in a personal protective welding device for a vision protection that includes an optical sensor (1), an opening with an optical element (2) with an adjustable permeability for a limitation of a permeation of a radiation from a luminous manifestation towards the view, where the optical sensor (1) for a detection of the luminous manifestation of an electric arc welding is placed inside the personal protective welding device, and the optical sensor (1) is connected with a control of the optical element (2), includes an activation light (3) that emits radiation that is detected by the optical sensor (1), so that the activation light (3) is placed within a range of the optical sensor (1), characterized by the fact that this optical sensor (1) is the same sensor that is used within the personal protective welding device l to detect the luminous manifestation of the electric arc welding itself, where the activation light (3) is controlled by a switch (4) that is connected to the activation of the electric arc welding in such a way that the switch ( 4) is activated before a transmission of an electric current between an electrode and a welded material,
