Auto-dimming technology

Auto-dimming technology used in 3M™ Speedglas™ welding lens filters enhance welder's free work with no need to take the hand shield up and down as the auto-dimming lens filter provides excellent visibility and protection both in dimmed and undimmed states.

Auto-dimming technology provides an absolute protection of welder's eyes against light radiation effect as even in undimmed state the lens filter allows only visible light to pass through and reflects ultraviolet and infrared rays. Thus, this technology significantly improves welding performance, quality and accuracy, as well as provides reliable protection of a welder's eyes and enhanced comfort during welding.
