| A: Eyes and face are easily damaged from various harmful factors when they are exposed, especially for welders¡¯ eyes. Statistically, there are about 1-3% eyes-damaged workers in China, while up to 34% in industrial department. When welding, the direct damages to welders come from arc flash radiation, rays, high-frequency electromagnetism and heat radiation, among them the arc flash radiation is the third harmful factor. In the industrial welding, heat source over 1000¡æ can engender high-intensity visible light, ultraviolet(UV),infrared(IR) radiation etc. The lens in our eyes are very sensitive to the rays, our eyes will become congested in several hours once the lens are attacked by the x-ray. And if exposed to UV too long, which also will cause electrooptic Ophthalmia with eye-pain, tears, photophobia and foreign matter in eyes, even if worse, resulting in cataract (pearl eye). The auto-darkening welding helmet can effectively stop all UV & IR rays, from damage to welders. At the same time, the helmet shell, which is made of the special material with high-heat resistance, can protect the welders from damage of the heat radiation. GAOCHUANG brand helmets also add an outside protection plate to the filter, which protects the filter against welding trash and can easily be replaced and prolong the lifetime of the welding helmet. |
