What glasses can argon arc welding wear to prevent drilling?

Argon arc welding needs to wear special argon arc welding cap for protection, which can be divided into color-changing argon arc welding cap and color-changing argon arc welding cap. Some argon arc welding caps with unsatisfactory color change performance will also be drilled at the moment of arc initiation. The degree of cobalt glass used in traditional argon arc welding cover should not be too low, and generally it needs to be above 10. The degree is too low, the brightness is too high when welding, and the eyes are uncomfortable.
