[0002] As we all know, during welding operations, the high-intensity light generated by the arc, including ultraviolet rays, infrared rays and visible light, can cause serious damage to the welder's eyes. Therefore, workers often wear welding masks when performing welding work. Among them, the ultra-low brightness filter face shield in the welding mask can still maintain a clear field of vision at extremely low brightness, while effectively filtering out arc light that may harm the eyes. Therefore, the design of this face shield usually combines new materials and advanced optical technology to provide a more comfortable and safer welding environment;

[0003] It is found during use that the existing welding face shields with ultra-low brightness filters are mostly fixedly mounted on the mask. When they are damaged, they cannot be replaced, and the workers can only replace the mask, which causes cost waste and reduces the work efficiency and effect of the workers in welding, thus resulting in poor practicality.
