The solar auto-darkenging welding helmet provides eye protection of welders against ultraviolet and infrared emissions. The fast response time prevents eye-flash or eye-injury. The shade of the lens can be adjusted according to the welding current. The automatic control system can discriminate the welding light from sunlight. The solar cell can supply energy from welding light light or natural light. Without external power, the backup lithium battery can supply energy for two years. It is not neccessary to switch off if you do not weld, and the helmet will be in sleep state. When you weld it can be automatically waked up to work.
This welding helmet is suitable for all arc welding, but does not provide protection against Autogen Welding or Laser Welding.
