A person who is working in the field of welding or just examining the welding process needs to wear a welding helmet .The reason why welding helmets are essential is because of the bright light given off by welding. Without taking safety measures, this light can factually burn the insides of your eyes and cause temporary or permanent blindness. Part of the reason is that mainly in dark places, the eye cannot adjust to the change in brightness fast enough to prevent damage. A good welding helmet not only protects you from rapid sparks, but also shields you from the extremely brilliant welding arc.
Today welding helmets have changed significantly. While they look quite a bit unusual today than they did years ago, you can still find two main types of welding helmet:
- Passive
- Auto-dimming
Whenever you picture welding helmets, you’re almost certainly thinking about manual, or passive as it’s also known. The main advantage to these passive helmets is that they often cost less. More recently, auto-dimming welding helmets have become more popular. These helmets, like the conventional manual ones, are a part of metal and a piece of glass. The auto-dimming helmets come in two types, some use infrared viewers whilst others use electricity to dampen the glass. Both use electricity.
