Detailed Product Description

auto darkening welding helmet are probably the most common, yet important type of protection equipment in the welding business, since without a special protection for the eyes, welding is nearly impossible. Auto darkening welding helmets are the most advanced models of protective apparel, but let's see why. We should start by saying that it is essential to understand the way the arc flash works, in order to explain the efficiency of auto darkening welding helmets. There are several types of light that radiate from the welding arc: ultraviolet (UV), high-intensity light and infrared (IR). Without protection against UV and IR eyes can suffer from permanent and severe damage: retinal burns and sight loss.
