The large arc-shaped thin-curved transparent cover can be rotated on the face or the top of the head on the elastic head clamp with the toothed knob. It can be used in conjunction with gas masks, dust masks, and work caps to achieve comprehensive protection.
The protective mask is divided into different types according to the use occasion: welding mask, safety protection mask, medical protection mask, gas mask and radiation protection mask.
1. The role of welding mask
Eye protection: double filter to avoid harmful ultraviolet and infrared radiation generated by arc, and damage to eyes caused by strong welding light, to prevent electro-optic ophthalmia.
Face protection: Effectively prevent splashes and harmful objects from work on the face and reduce the occurrence of skin burns.
Respiratory protection: The airflow guide can effectively reduce the harmful gas and dust released from welding to the body and prevent the occurrence of pneumoconiosis occupational diseases.
