Principle of automatic dimming mask:

1. When the electric welding worker performs the electric welding operation, he picks up or puts on the electric welding mask, and the observation window lens on the electric welding mask is transparent. Welding workers can clearly observe the position of welding objects and welding points.

2. When the electric welder performs welding, a strong electric spark is generated at the moment when the arc starts, and the moment the photodiode on the mask receives the arc light changes from transparent to opaque. The filter can be set according to the standard, and the action time of the display can be set as needed to ensure that the eyes of the welding workers will not be injured.
