Welding masks are labor protection products used to protect the human face when people perform electrical welding, metal cutting and welding. This type of product not only protects the human eye from being damaged by ultraviolet rays, infrared rays, and welding light, but also prevents foreign objects such as metal splashes from harming the human face. In addition, some high-tech welding masks will also be equipped with gas masks to reduce the harm of toxic and harmful gases to the human respiratory tract.


So, what are the common welding masks in the current labor insurance supplies market? What are its advantages and disadvantages?


What are the advantages and disadvantages of welding masks for labor protection products and facial protection?

Next, let the tree-lined building materials network explain briefly for everyone.


1. Handheld welding mask:


This type should be regarded as the most primitive type of welding mask, only simple handles and filters. The user grasps the handle of the welding mask with one hand, and performs welding with the other hand. When welding, it is necessary to use a mask to block the strong light of the welding. If the hands are not well matched, it is easy to cause strong eyes Light burns. Therefore, the hand-held welding mask is operated with one hand, the efficiency will be relatively low, and in order to protect the eyes, the welding quality will not be very high.


2. Head-mounted welding mask:


This type of welding mask is more advanced than the handheld welding mask and belongs to the improved version. Moreover, when this type of welding mask is used, it does not need to be held by hand. However, because the filter is black, and it is off when not in use. Therefore, in use, the observation window needs to be shaken off with the force of the neck, and it will cause damage to the eyes if it is not timely. In addition, opening and closing the observation window multiple times for a long time can easily cause fatigue for users and reduce work efficiency.


3. Automatic dimming welding mask:


This should be the most advanced type for now. This type of welding mask is composed of an automatic dimming screen, a side window and a helmet, and uses advanced light detection technology and liquid crystal technology. When welding, the light generated by welding (mainly infrared or Ultraviolet light) to trigger the control circuit of the liquid crystal, and will apply a corresponding driving signal to the liquid crystal (transmissive TN liquid crystal) of the mask according to the preset light transmittance.


What are the advantages and disadvantages of welding masks for labor protection products and facial protection?

The automatic dimming welding mask is more advanced than the head-mounted welding mask and the handheld welding mask, which not only maintains the quality of welding, but also enhances the efficiency of work, allowing workers to perform welding better, faster and more safely. jobs.


In fact, not only choose welding masks, when choosing other labor protection products, you should first understand the advantages and disadvantages of different types of products, and then combine the needs of the operating environment, choose a suitable labor protection products, so as to better protect yourself .
