WELDING GOGGLES AUTO-DARKENING SAFETY GLASSES WELDING MASK Technical data : Filter size: 190.5 mm - 77.5 mm - 76.25 mm Viewing field size: 122.5 mm - 35 mm Shade: DIN4 Working shade: DIN5-DIN9/DIN9-DIN13 Switching time: 3/10000 s Sensitivity adjustment: STEPLESS Delay: 0.1s-1.0s Delay time adjustment: STEPLESS Power supply: CR2450 Operating temperature: -5°C - +55°C Storage temperature: -20°C - +65°C Protection class: DIN16 AUTOMATIC GOGGLES WITH FACE MASK MAR-POL The goggles are equipped with an automatic darkening filter, allowing you to work without removing them. Special sensors located in the mask automatically detect the start of the welding process, activating the auto-darkening function. After welding, the filter automatically returns to its brighter state. The filter is powered by a solar cell and also battery-assisted. The goggles are used as personal protective equipment during arc welding and cutting processes (TIG, MIG, MAG, MMA, SAW, PAC). Lightweight, ergonomic, and perfectly fitting to the face, these goggles provide effective and very comfortable eye protection. The goggles are equipped with 2 photo-sensors which are located 2 in the upper part of the lens. The use of welding goggles is particularly useful in places where access to the welding point is difficult. Often during renovation work in the field, access to the welding point with the helmet is limited or even impossible. In such cases, welding goggles are irreplaceable.
