Auto Darkening Welding cap is often used in the welding work to protect the eyes of a Tool With the improvement of people's awareness of labor protection and the improvement of welding quality requirements, the original issue of hand-held fixed shading mask can not adapt to these requirements, auto darkening welding hat is made. So in the end cap auto darkening welding which characteristic? Only find out its characteristics, you will be tempted whom the.
Question one: What is the arc? Auto darkening arc welding caps to prevent damage to the eye it?
A: arc welding process in direct contact with the eyes to the most reluctant. Arc the release of several rays, including: ultraviolet, infrared and high-intensity visible light. UV and IR people's eyes will cause permanent damage; visible though the eyes will not cause permanent harm, but it will make the eyes of welders are temporary discomfort, as if your eyes are exposed to the flash as usual. Light-lens mask with double anti-piece group, namely: anti-UV and anti-infrared lens. Generally only mask UV or infrared lenses, can not be two kinds of damaging rays while eliminating. Light control of all company products have dual anti-mask function.
Question 2: engaged in welding work if you do not wear masks have risks?
A: The eyes and face and so is the body's organs directly exposed to the outside world, easily hurt by harmful factors, in particular the most likely to hurt the eyes. According to statistics, China had approximately 1-3% of the workers suffered eye injuries, the industrial sector as high as 34%. In the welding work on the eyes and facial skin poses a direct threat are: arc radiation, ray, high-frequency electromagnetic field and thermal radiation. Among them, the arc radiation harmful factors in the lives of all the third, the risk to workers is great. Industrial welding process, heat above 1000 degrees, to produce light, ultraviolet, infrared and other rays, while the eye of the lens on the ray most sensitive X-ray radiation, a few hours to make eyes, and prolonged exposure to strong ultraviolet, can generate electric ophthalmia and have eye pain, tearing, photophobia, foreign body sensation, etc., can lead to severe cataracts. Light control can mask the mirror group to ultraviolet and infrared rays, etc. All filtered, so that the welder's eyes are fully protected. Also, because there are heat-resistant materials used in mask performance, so they can make the user from radiation hazards. Control mask is still the company's optical lens group of the former with a foreign security chip, which makes the lens group from welding spatter damage to property, but outside the security chip to facilitate change and improve the life of light control welding mask.
Question 3: In order to welding eye protection, should choose what kind of shade made?
A: Some people think that shading is linked to the degree of eye protection, and therefore the greater the value to better protect the eyes. But in fact light-control masks to filter out most harmful UV and infrared, so shading the choice of number is not a question of comfort is comfort. No. shading values, said a specific shade number is provided under the shade level, welding workers should choose one of the most comfortable way, and application-specific conditions to maintain good visibility. Choose a shade number so you can clearly see from the arc points to help you improve the level of welding. Products?? Light control mask, you can adjust based on user preferences shading his number, and the rapid changes in optical properties can not hurt your eyes (from the arc response time of less than 0.2 milliseconds).
