Welding helmet is a helmet that protects the face, neck and eyes from dangerous sparks and heat, as well as infrared and ultraviolet rays emitted during welding. The two main parts of the welding helmet are the protective helmet itself and the window where you can see what you are doing. You should choose a welded helmet based on the quality of the filter, called a lens hood, overall comfort, and versatility. A person wearing a welding helmet carries out welding.
Both professional and amateur welders need a high-quality welding helmet that is easy to use and suitable for their type of work. In the past, it was enough to use a helmet like shield, which can only cover the face with a permanently darkened lens shade. The protective cover turns up and down between the welds, which is very inconvenient. It is difficult to see what you are doing. It is also difficult to use in a narrow space, such as under a car. The current technology has made the welding helmet with automatic darkening lens, which can block 100% infrared and ultraviolet rays, but it can only filter the visible light of the welding arc during the welding process. In order to protect the face, neck and eyes from sparks and heat, ultraviolet and infrared rays generated during welding. Video screen is the most important and expensive part of welded helmet. Its darkness level or range corresponds to the energy output of the welding torch. For welders using the same current and the same metal, they can use "fixed" eye masks and various lens protective covers to sense what you are welding and darken it to the correct shadow.
Another rating of the automatic dimming lens is the time it takes to darken after the arc begins. It is safe to use an electric welding helmet that darkens in 4 / 10 milliseconds, because your eyes can't feel the change of light during that time. Some helmets are battery powered and can be used indoors, but they must be charged. Other types of helmets use sunlight and are suitable for outdoor use, but are incompatible with darkness. Of course, you also need a large enough lens to give you enough vision. Another consideration is the appearance of the welded helmet, as some models have interesting shapes, decals and colors. Some models can be equipped with accessories, such as breathing filter, which can inhale fresh air and reduce fog. Other filters have removable displays, so you can upgrade or replace them as needed. Welding helmets can also significantly reduce the risk of cancer among welders. Welding goggles.
