Welding mask refers to a tool that protects the safety of operators during welding and cutting operations. The popular name is welding helmet.
Principle:The high-strength polymer material is formed at one time, and it does not leak light, which is more suitable for the current trend. The complete variety can adapt to the needs of a variety of working environments.
Solar light-controlled electric welding mask, the welding workpiece can be clearly seen before the arc starts, and it will automatically become dark when the arc starts. The light-controlled electric welding mask is a new type of electric welding mask that uses light detection technology and liquid crystal technology. The corresponding English translation is Auto Darkening Welding Helmet. The principle is that the internal photoelectric sensor circuit detects the light (mainly infrared or ultraviolet) generated during electric welding, after amplification, triggers the control circuit of the liquid crystal, and according to the preset The light transmittance of the mask applies the corresponding driving signal to the liquid crystal (transmissive TN liquid crystal) of the mask. Liquid crystal as a light valve will change its light transmittance. The infrared and ultraviolet rays that are harmful to human eyes will be filtered out. At the same time, the strong light is reduced to the 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 allows a clear observation of the entire welding process. It is an ideal substitute for traditional welding mask.
The role of welding mask:
1. Eye protection: double filter to avoid harmful ultraviolet and infrared radiation generated by arc, and damage to eyes caused by strong welding light, and prevent electro-optic ophthalmia.
2. Face protection: effectively prevent splashes and harmful bodies from work on the face and reduce the occurrence of skin burns.
3. Respiratory protection: airflow guide, effectively reduce the harmful gas and dust released by welding to cause harm to the body, and prevent the occurrence of pneumoconiosis occupational disease.
