auto darkening welding helmet black protective mask

There are many hazards in welding processes: ultraviolet rays, infrared rays, strong light, welding smoke and organic gases, etc. Usually, welders use handheld non-variable light welding masks, which need to cover their eyes in the moment of starting the arc. During the welding process, it often causes the eyes to be exposed to harmful light radiation for a moment. The automatic variable light welding mask solves this problem and can provide the greatest protection for the eyes of the welder. The automatic variable light welding mask is composed of three main parts: the mask housing, the window mechanism, and the head-mounted mechanism. The mask housing is the main body of protecting the light pollution and the welding melt spatter during welding. It bears the installation and positioning of the window mechanism. The window mechanism is used to protect the ultraviolet rays during welding and the visible and invisible substances that may harm the eyes. The head-mounted mechanism is mainly used to fix the mask in the position of the human body, making the user more convenient and more efficient to complete the work.
