Welding mask good or bad identification methods

Welding mask, before welding can clearly see the welding workpiece, the arc moment automatically dimmed. Light control welding mask is a kind of application of optical detection technology and LCD technology, a new welding mask. The principle is that the internal photoelectric sensing circuit detects the light (mainly infrared or ultraviolet) generated during welding, after amplification, triggering the liquid crystal control circuit, and according to the preset light transmittance in the mask liquid crystal ( Transmissive TN liquid crystal) to apply the corresponding drive signal. Liquid crystal as a light valve will change its light transmittance. The filter will be filtered to produce harmful infrared and ultraviolet rays. At the same time weakened glare to the low light that the human eye can withstand. Compared with the traditional welding mask, not only to protect the health of operators, but also can clearly observe the whole process of welding.

Welding mask refers to the tool in the welding operations to protect the safety of workers. How to distinguish the welding mask it? Welding mask knowledge and identification of welding mask is good or bad way:

1, welding mask should not be stored in: acid, alkali, high temperature, sun, humidity and other premises.

2, welding mask procurement: companies must purchase a China Labor Protection Products Quality Supervision and Inspection Center inspection report or authoritative certification of the product, the purchase of the product experience received before use.

3, the use of welding mask period: from the date of use of the product, the welding cap life ≥ 6000 welding hours. Poor quality products without test report and certification, cheap, short service life, unstable light not only can not stop the red UV, but also make the pupil forced to enlarge, resulting in a large number of red ultraviolet injection, causing eye burns.

4, Enterprise Security Department should deal with the use of auto-matte electric welding mask due to expire, to carry out spot checks, after passing before continuing to use, sampling failed is scrapped.

5, perfect after-sales service: welding mask replacement one week (no one is damaged and appearance problems), two years warranty.
