Welding mask Artotic SUN 9F Black

The Artotic SUN 9F Black welding mask is a chameleon mask, i.e. an automatic dimming light filter is used as an element that filters out radiation. The control of the light filter's operating parameters is located outside the mask. On one side, there is a sensitivity control knob and a welding/grinding mode switch, and on the other, a dimming level control knob and a delay switch. Two independent sensors located above the viewing window provide optical detection of the start of welding. The mask is powered by a dual power supply, for greater reliability - a solar battery and 2 additional replaceable Li-Mn batteries.
