AWTOOLS máscara de soldar automática escura LYG-7 com classe ótica 1/1/1/2, campo de visão 92x42 mm, tonalidade DIN 4/9-13, modo de esmerilhamento

With a true 1/1/1/2 optical class, the AWTOOLS LYG-7 eliminates distortion and delivers razor-sharp clarity across the entire 92 x 42 mm viewing area — every weld pool detail stays visible without lifting the hood. The auto-darkening filter reacts in just 1/25,000 of a second, shielding your eyes the instant the arc strikes, while permanent UV/IR protection up to DIN 16 keeps harmful radiation out even in the light state.

Overview

Built for professional welders and demanding hobbyists, the LYG-7 combines a lightweight, high-impact polypropylene shell with a versatile auto-darkening filter. The external shade knob lets you steplessly adjust from DIN 9 to 13 to match your process, while the integrated grinding mode means you can switch from welding to surface prep without changing helmets. Two independent arc sensors ensure reliable triggering even in tight or obstructed positions, and the solar-assisted power system with replaceable CR2032 batteries keeps the filter ready for long work sessions.
