Almaz welding mask, automatic, with 90x35mm viewing window, 2 sensors, for welding and grinding, model AZ-ES3003-G01. The welding mask features spectral filtering technology, photoelectric control technology, and liquid crystal light control technology, combined in one high-tech product. The automatic darkening filter (ADF) works on the principle of photoelectric induction, causing the liquid crystals to switch from a light to a dark state as soon as arc light is detected and automatically returning to the light state once welding is completed, providing protection for the user's eyes and skin from the ultraviolet radiation generated by the arc and sparks.
