The crystal 2.0 welding helmet features automatic shading controls to adapt to brightness of the welding arc. When operating in its “light” state, the helmet allows for 31% visible light transmission with a broad visible color spectrum. When using the helmet in “dark” mode during work it provides a high-contrast view of the welding pool. The sensitivity controls and sensors can be adjusted to suit the user, and the adjustable headband is designed to reduce strain from the helmet on the wearer’s shoulders and neck. optrel AG; www.optrel.com
