The Solar Auto-Darkening Welding Helmet provides eye protection of welders against ultraviolet and infrared emissions. The shade of the lens can be adjusted according to the welding current. The electronic control system can discriminate the welding light from sunlight. Solar cell can supply energy from welding light or natural light, and it will auto-off in about 8 minutes if you do not weld so your battery can last longer. The fast response speed prevents eye-flash or eye-injury.
