welding is a work of great harm to eyes and face. In the process of welding, a lot of arc radiation, rays, high-frequency electromagnetic field and thermal radiation will be produced. If the construction is carried out without wearing the welding mask, it will cause great harm to itself.

   During the welding process, heat source above 1000 degrees, can produce a strong light, ultraviolet and infrared ray, and the people in the eye lens to ray is most sensitive to exposure to X-ray radiation, after a few hours makes bloodshot eyes, long time contact with strong ultraviolet ray, can produce electric ophthalmia and have sore eyes, tears, afraid of light, foreign body sensation, severe cases can cause cataracts.

   The mirror set of the welding mask can filter out ultraviolet rays, infrared rays and other rays, so that the welder's eyes are fully protected. At the same time, because of the heat resistance of the material used in the welding mask, the user can be protected from the harm of thermal radiation. In addition, an external protection piece is added in front of the mirror set, which makes the mirror set free from the damage of splashes during welding, and the external protection piece is easy to change, thus improving the service life of the mask.

What is the advantage of automatic welding mask over ordinary welding mask?

1. Free your hands

The mask is not a hand-held mask. It directly frees your left or right hand, allowing you to operate with both hands. In this way, the difficulty of welding is greatly reduced, and the quality of welding is greatly helped, so that the quality of products can also be greatly improved.

2. Protect your eyes

The black glass used in the ordinary mask can only protect the strong light during welding, but cannot protect the infrared and ultraviolet rays which are more harmful to eyes. It is easy to induce electro-optic ophthalmitis if used for a long time. In addition, due to the characteristics of black glass, arc can only rely on experience and feeling, can not see the solder joint. The automatic photochanging welding mask makes use of the characteristics of liquid crystal molecule rotation. When there is no arc light, the light transmittance of the welding mask is high, and it is easy to see the machining parts. When there is arc light, the light transmittance of the welding mask decreases and the vision is protected.
