A welding helmet is a protective gear used by many welders to protect their eyes and face during welding. These helmets are mandatory to wear when you are doing arc welding as the high intensity of ultraviolet rays and gamma radiations are emitted during the welding. These welding helmets are used in the same way as any other helmet. The construction of welding helmets varies from company to company and from model to model. There are numerous models of welding helmets available in the market. But each helmet has its own significance.

Many people get confused and think that all the welding helmets are same. But it is completely false. Each helmet has its own significance. Mentioned below are the varieties of the welding helmets.
Standard or passive helmet: These helmets are popular with those welders who don’t weld on a large scale. These types of helmets are found with non professionals who know the art of welding but don’t weld too much. These helmets are made from precast plastics with a window in the middle of it. The filter lens is fitted inside the window which provides the protection against the ultraviolet rays and infrared glazes.
Auto darkening helmets: Auto darkening helmets provide you with the auto darkening feature. These helmets are great for the beginners as they don’t have to change the helmets when working on different materials. The lens used in this helmet automatically gets dark enough when the torch is lit. The lens gets dark according to the metal which is used for welding. This lens catches the intensity of ultraviolet rays with the help of a light sensor and the lens gets dark according to the intensity of rays that are emitted.
Battery and solar powered: Battery and solar powered helmets have a solar panel which automatically charges the inbuilt Lithium ion battery. These helmets do not need to get charged before they can be used. These helmets are a great choice for those people who want to start their welding work as soon as possible and don’t want to wait to start their work. The plus point that these helmets have is that they keep on working after the battery dries out. It uses the power generated by the solar panels and continues to work on that power.
