Light filters ESAB (ESAB) 90x110mm. ESAB filters for welding helmets provide excellent UV and IR protection as well as heat protection. Light filters are quite fragile and therefore must be used with protective inner glasses made of polycarbonate and outer protective glasses (glass or plastic). The main component of welding masks is a light filter installed in it to protect the organs of vision from infrared and ultraviolet radiation of the welding arc.
