A good Welding Shield is one of the most important pieces of P.P.E (personal protective equipment) a welder must wear. It protects the user eyes and skin form sparks as well as the ultraviolet and infrared light which is cast during the welding process. An auto tinting welding helmet blends the best in protection with the ease of hands-free use. Auto tinting helmets use a photosensitive filter to “tint” the viewing area to a pre-set shade automatically before the light hits the user’s eye.
