The means of individual protection of face (shield shielding facial) caliber MSKh-11p is intended for the protection from the drops of molten metal and hot particles. Shield welding (further on the text - shield) with the automatic light filter (ASF) is high-tech production, which combines the technology of spectral filtration, technology of photoelectric induction control with the technology liquid-crystal of optical control and is intended for the eye protection and face from the sparks, drops and harmful emissions of welding arc with the welding in the regimes MMA, MIG-MAG and TIG.
Light filter ASF automatically will be darkened with the ignition of welding arc and automatically it returns to the initial state (transparently) after arc extinction. Is the complex optical connection, which consists of two liquid-crystal cells, three polarization films, shielding ultraviolet and infrared (UF/IK) filter and shielding glass. Filter UF/IK ensures a constant eye protection welder from the harmful effects even when automatic light filter it will not operate.
