It is a hood protector used during welding to protect the eyes, face, and neck from burns, ultraviolet rays, sparks, infrared light, and heat. The welding mask consists of a window covered with a filter called a lens shadow where the welder can do his work.
Face shields protect your face from flying debris and provide full protection for your entire face. They are usually secured over or around the head with an adjustable band. Workers need face shields in many industries, one of which is welding. Welders engaged in any welding-related activity, such as cutting and grinding metal, must wear a face shield. Face shields ensure protection from the intense heat, optical radiation, and sparks from arc-welding equipment.
Why should it be used?
Burns occur when you are exposed to bright ultraviolet (UV) light. This can be caused by all types of UV rays, but welding torches are one of the most common sources. Flash burns can have a strong effect on your both eyes. Welding arcs emit light at both IR and UV wavelengths.
High-quality auto-darkening masks always protect you, as they provide UV and IR protection, even when the helmet is not activated. A welding mask is one of the most important parts of a welder's personal protective equipment.
This mask protects the eyes and skin not only from intense sparks but also from ultraviolet, infrared rays, which potentially impair vision. The welding mask should be light and well balanced and has plenty of lights and an arc sensor. Light sensors filter additional light in standard welding procedures, while arc sensors are associated with intense bright light generated by welding arcs.
Most welding mask windows can be made of colored glass, colored plastic, or a variable density filter made of a pair of polarized lenses. It also prevents retinal burns that can cause vision loss. Welding protectors have different darkening parameters.
