Any person who does the welding job, be it as a profession or just as a time-pass, would undoubtedly need a welding helmet. It is one of the most vital protective gear for a welding worker. It protects one from the harmful sparks, molten metal and can even save one from possible harms that go by unnoticed. A solar powered welding helmets is one of the most sought-after helmets by the welding experts. The www.safetyandhealthmagazine.com/ strictly recommends usage of a good quality welding helmet to avoid accidents and harm during the welding works.
The welding torches and guns often emit infrared and ultraviolet light rays. If you expose your eyes directly to such light emissions, it can cause pain and strain of eyes. It can even result in lasting after effects like blindness of eyesight. Hence, usage of welding helmet is a must for welding works. As time progressed, simple helmets have stepped down to pave the way for modern helmets that ensure complete protection of the eyes. Auto-darkening helmets are one such modern helmet. It strictly ensures that the eyes remain safe and secure even while doing complex welding jobs. Auto-darkening helmets are available in two forms. They are available as battery operated and as solar power operated ones.
Battery Powered Auto-Darkening Helmets
The auto darkening helmets with ADF lenses will need a power source to operate well. This power source is usually a battery or solar energy. The battery-powered helmets make use of rechargeable lithium battery or a group of AAA standard batteries. Usually, battery-powered helmets have a switch near the ADF lens controls to power on and start initiating the sensors.
Relying on battery-powered helmets might seem to be more convenient. But, during the due course of time, often welders face some issues due to battery powered helmets. Lithium batteries start giving out after a couple of years of continuous usage. While trying to replace the battery, you will have to buy a new one from the original manufacturer itself. This might cost a large amount too. In case you use standard batteries, replacement is much easier. But in that case, you will have to keep replacing it more often.
Another issue is that as the battery works on a power switch, the welders can forget to switch off the switch after use. The battery might get drained off by the time he/she returns to work the next day. In case they forget to switch it on before work, it can cause serious harm to the eyes.
Solar Powered Auto-Darkening Helmets
The solar powered helmets make use of photovoltaic cells as their source of power. It is often kept on the top portion of the helmet. It helps to keep the helmet in good working condition for some years. It is charged up using the solar panel. It has an automatic power on and off option. Hence the welder need not bother about switching it on before work or switching it off after work. Usually, professional welders who work under sun exposure a lot use solar powered helmets more than battery operated ones. The only disadvantage is that it has a short lifespan and also takes time to recharge.
