Безусловно, сварка металла является одним из most dangerous to humans, because all the work on welding is accompanied by a constant release of harmful substances and factors. One of the most dangerous are: electric arc, bright luminescence, toxic gases, infrared and ultraviolet radiation. That is why, in order to maximally protect themselves from such a “bunch” of troubles, when welding metal, workers use a special protective mask, which is called “the welder's mask”.
Вначале отметим, почему так опасна для человека electric arc. This is in the process of such work is the basis of electric arc welding. In this case, the temperature of metal nodes can reach 8 or more thousand degrees. With such heating, local melting of steel occurs, due to which the compound is very high quality and reliable. But the "side" effect here is intense radiation in the infrared, optical and ultraviolet range. All this luminescence has a very negative effect on the eyes of the worker, which can lead to various diseases and even complete loss of vision. Therefore, the mask of the welder is an integral attribute when performing this kind of work.
To date, there are 4 main types of these devices:
Absolutely each of these species is supplied with a thicktinted glass. Also the mask of the welder (“ASF” including) may have in its design a special light filter, which includes a cover glass and a plexiglas substrate.
This part of the tool is made ofspecial non-conductive material, which by its properties is resistant to splashes of metal heated to 8 thousand degrees Celsius, sparks and electric arc. It is best to purchase such masks that have removable mechanisms to replace this glass. The fact is that during long-term welding, its surface very quickly becomes “stained” with splashes of metal and it is almost impossible to see the place of welding through such a tool. Therefore, do the calculation that the device had a removable glass mechanism (with a sealed mount).
Below are the most popular firms that are engaged in the production of such parts as the mask of the welder:
The most expensive mask welder, and accordinglythe most high-quality in its characteristics is the product of the company "Chameleon". It costs more than all the other "brothers" - about 2-2.5 thousand rubles. And this is despite the fact that some types of masks can be purchased for 160-200 rubles. In general, the cost of high-quality parts varies from 1 to 2 thousand rubles.
When choosing, pay special attention to the fact that the mask is comfortably adjusted "under the head" and does not have too heavy weight.
