Welding - injury-causing type of activity. The welder risks to get burns of the face and eye, to get poisoned with gases which are emitted in the course of welding therefore use of mask is absolutely necessary. It is important to pick up welding mask so that it, protecting, did not prevent work.
Instruction
1. The cheapest type of welding mask represents guard with the light filter to which the handle is attached. The welder holds guard for the handle at the person during operating time. It is obvious that such mask badly protects from drops of the heated metal and evaporations of gases, besides during the work with such mask one hand of the welder turns out busy what is very inconvenient. Choose such type of welding mask only for the most primitive household welding.
2. The traditional mask is put on the head, that is both hands in the course of work will be free. The mask completely closes the head and neck, protecting from drops of the melted metal. The guard of traditional mask completely leans back after completion of welding, in it its shortcoming as at the cast-away guard it ceases to protect eyes, and to the welder it is necessary not only to work with the welding machine, but also to carry out upholstery of seam and other operations which can lead to injuries. To solve this problem masks in which not all guard but only the light filter, at the same time eyes remain rises have been developed protected by special hood.
3. When choosing mask pay attention to its size and weight. Surely try on it, it, as well as any headdress, has to fit you. If welding - your regular job, is desirable to buy the most comfortable mask which will be supplied with special regulators of distance from the light filter to the person, inclination of mask, depth of its landing.
4. Buy mask to which in the package filters are included, it will allow to replace quickly become soiled or scratched filter. If you carry out specific welding at which toxic substances are emitted, the mask with air filters or air supply is necessary for you.
5. Modern expensive welding masks are supplied with special chameleon filters, these light filters are darkened during 1 millisecond after the beginning of welding and return to normal condition when welding is finished, that is the welder does not have need to lift the light filter, he and through it will see seam.
