Of Course, the welding metal is one of the most dangerous to humans, because all the work of welding is accompanied by a constant release of harmful substances and factors. One of the most dangerous are: electric arc, a bright light, toxic fumes, infrared and ultraviolet radiation. Therefore, in order to best protect themselves from such “bouquet” of trouble when welding metal workers use special protective mask, called mask of the welder.
First we note why it is so dangerous to humans electrical arc. This are in the process of such work is the basis of the fundamentals of electric arc welding. The temperature of the metal nodes can reach more than 8 thousand degrees. When such heating occurs local melting of the steel, so that the junction is of very high quality and reliable. But “adverse” effect here is intense radiation in the infrared, optical and ultraviolet range. All this glow has a very negative impact on the eyes of the worker, which can lead to various diseases and even full loss of vision. Therefore, the mask of a welder is an essential attribute when performing this kind of work.
At the moment there are 4 main data structures:
Every single of these types is supplied with thick tinted glass. Also, the mask of the welder ("ASF") may have in its design a special filter, which included a cover glass and a substrate of Plexiglas.

This part of the tool is made of special conductive material, which properties are resistant to the splashes of hot up to 8 thousand degrees Celsius metal, sparks and electric arc. It is best to buy these masks that have removable mechanisms to replace the glass. The fact that in continuous welding, its surface is very fast “salafimedia” spray of metal and see through such tool weld almost impossible. Therefore, make the calculation that the device had a removable mechanism glass (with sealed mounting).
Below are the most popular firms that manufacture such details as the mask Sardica:
The Most expensive mask of the welder, and therefore the most high quality according to its characteristics, is a product called "Chameleon». It costs more than any other “fellow” is about 2-2,5 thousand rubles. And this despite the fact that some types of masks can be purchased for 160-200 rubles. In General, the cost of quality of parts varies from 1 to 2 thousand rubles.
If you choose, pay special attention to the mask is regulated by the “head” and was not too heavy weight.
