What Is an Auto-Darkening Welding Helmet?

Welding mask is a tool that protects the safety of workers during welding and cutting operations. Popularly known as a welding cap.

The role of welding mask:

1. Eye protection: double filtering to avoid harmful ultraviolet and infrared generated by arc

High-strength, high-strength, non-leakage polymer materials are more suitable for today's trend, and a full range of products can meet the needs of various working environments.

The solar light-controlled welding mask can clearly see the welding workpiece before starting the arc, and it will automatically darken at the moment of starting the arc. The light-controlled welding mask is a new type of welding mask using light detection technology and liquid crystal technology. The corresponding English translation is Auto Darkening Welding Helmet. Its principle is that the internal photoelectric sensor circuit detects the light (mainly infrared or ultraviolet) generated when welding is performed, and it is amplified to trigger the control circuit of the liquid crystal, and according to the preset The light transmittance of the mask applies a corresponding driving signal to the liquid crystal (transmissive TN liquid crystal) of the mask. Liquid crystal as a light valve will change its transmittance. Welding is filtered to produce infrared and ultraviolet rays that are harmful to the human eye. At the same time, the strong light is reduced to a weak light that the human eye can withstand. Compared with the traditional welding mask, it not only protects the health of the operator, but also can clearly observe the whole process of welding. Is an ideal alternative to traditional welding masks ^[1]
