![]() They’re cheaper because they are only designed to last a few years (usually up to three). Older helmet models had fixed batteries, which means you couldn’t replace or recharge them. Many helmets also use an auto-off feature, which ensures that you conserve energy. Therefore, we believe that auto-darkening welding helmets can be more economical than a full battery-powered helmet. ![]() Solar power technology can also preserve your battery’s life because it does most of the work. Solar-powered helmets are usually lighter, so you can wear them for extended periods. Therefore, you don’t have to weld in the hot sun to get a charge. Once your arc is activated, UV light generated by the arc charges the solar panel for the welding hood, which then powers all the electronics. The battery is designed to power the hood or mask initially for when you start the welding arc. How Does A Solar Powered Welding Helmet WorkĪ solar-powered, automatic-darkening welding helmet uses both battery and solar power. This is especially true when talking about auto-darkening helmets. Some people think that the word “solar” always means that it is powered by the sun, but it’s a common misconception. Most auto-darkening welding helmets have solar power technology. In this way, they stay in good condition and are always ready to help. If you need to work on your welding project without delay, you might want to learn how to charge a solar-powered welding helmet.
