Protective measures are very important for a brawler. Without them, a quarrel is not only very dangerous, but also practically impossible. Welding masks are necessary when performing both small and large welding works. They primarily protect the eyes and face, as well as the respiratory system of the specialist performing the work. Mask of the welder — one of the main elements of the equipment. This is a measure of personal protection.
A correctly selected welding helmet will protect the skin from sparks, as well as from ultraviolet and infrared radiation emitted by the welding arc, which is very harmful to the eyes.
Today, all means of individual protection of a welder, including welding masks, must comply with strict safety standards that are observed around the world.
Types of masks
There are two types of welding helmets:
- automatic,
- passive.
The latter are easier to use. The welder himself decides what filter he needs, and then mounts it. The passive helmet is ideal for fighting MMA or migomatov. It is also a relatively cheap product. Of course, this solution has its drawbacks. After the arc goes out, the impression of darkness may appear, which may make it difficult to work. On the other hand, an unstable or brighter arc can harm the eyes. The passive mask can be burdensome during work, because every time the master stops fighting, it needs to be removed or raised.
Automatic masks are more expensive, but here you can count on the best quality and comfort of work. First of all, the product automatically reduces the light transmission coefficient when the welding arc is ignited. Some standards for these helmets regulate types of optical classes.
Auto-darkening masks
In automatic masks, automation is controlled by optical and electromagnetic sensors. When the arc is ignited, an optical sensor is activated, which transmits a signal to the automatic dimming filter. The liquid crystal screen is fixed in a certain phase, which depends on the strength of the detected arc. When the arc goes out or its intensity decreases, the sensors make the image brighter. They do not react to an arc, but only to a change in the course of the force lines of the field. However, you should know that these functions are intended only for professional helmets.
Welding mask with ventilation
A welding helmet with a ventilation hole will prevent the accumulation of hot air around the head. As a result, humidity decreases, and the master can breathe freely. However, this solution is recommended for professionals, most amateurs are completely satisfied with classic solutions.
