The Bossweld 51 x 109mm electronic welding lens upgrades a standard flip-up welding helmet or shield to electronic auto-darkening switching, so the lens darkens for you the instant you strike an arc.
Among the different types of welding lenses, an electronic auto-darkening lens like this saves you flipping a passive shade up and down, letting you see the work clearly at shade 3 then darken to shade 10.5 when you weld. It is solar-powered with a battery cell and designed to drop into Bossweld lift-front helmets, making it an easy way to add auto-darkening without buying a whole new helmet.
