Automatic dimming filter welding mask history

  The history of automatic dimming filter welding mask can be traced back to 1976, when the Swedes invented the world's first automatic dimming welding mask. This mask uses the photoelectric principle, which can change from light to dark at a very high speed at the moment when the welding arc is generated. Since then, the automatic dimming welding mask has been favored in the international welding industry, and in 1982 and 1989, respectively, it was promulgated by Germany and the United Kingdom as the relevant standards for electronically controlled welding window covers and glasses.

In the early 1990s, China began to develop photoelectric automatic color changing welding protective masks. As a company, Xunan Technology, its fist product - welding protective mask, will automatically dim in the encounter of arc light, which has almost become a "standard" welder hands in foreign countries. Compared with the traditional black glass sheet welding mask, this kind of automatic dimming welding mask adopts high-quality optical coating, which can greatly reduce the damage of harmful rays in the arc light to the eyes.
