An auto darkening welding helmet, also known as an auto darkening welding mask or auto darkening welding hood, is a type of protective headgear used by welders during welding operations. It includes a specialized lens that automatically darkens in response to the intense ultraviolet (UV) and infrared (IR) light emitted during welding. This automatic darkening feature protects the welder's eyes from the harmful effects of the intense light, including potential eye damage and temporary blindness. The lens typically transitions from a lighter shade to a darker shade within milliseconds of the arc being struck, ensuring constant eye protection and visibility during the welding process. Additionally, these helmets often come with adjustable settings, such as sensitivity and delay controls, to match specific welding requirements and improve comfort for the user.
