- Solar energy auto-darkening welding helmet is a set of spectral filtering technology , photoelectric inductive control technology , liquid crystal light control technology in one high tech products.

- Auto darkening filter (ADF) works with the photoelectric induction principle, which makes the liquid crystal change from the bright state into a dark state in receiving the arc light and automatic back to dark state when welding is finished , thereby protecting the user's eyes and face skin from the arc , splash and infrared I ultraviolet radiation.
