AUTO-DARKENING WELDING HELMET
MEGA – 550S
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 / ultraviolet radiation.
