Why Is Optical Clarity Important While Welding?
Auto-darkening welding helmets carrying the EN 379 – 1/1/1/1 rating deliver even shade levels across the full height and width of the viewing area.
The benefit is it eliminates the traditional trial-and-error game of trying on helmets and determining which one has the best viewing lens. Welders looking to upgrade a helmet now know that one with a 1/1/1/1 optical clarity rating will deliver a perfect view and the best-quality lens. It also means that you know when you buy a helmet that is it up to a certain standard that all manufactures are tested against.
“Welding is not an easy process, especially when you think about welders who wear a helmet for the better part of an eight- to 10-hour shift, sometimes working on exotic, thin, or expensive materials. For the welder to be able to perceive subtle variations in the ever-changing arc and weld puddle, the clearer the view, the better. When you weld, you constantly adjust your angle and travel speeds based on changing conditions at the arc. As a result, the capability to clearly view what is going on in the weld puddle will help you deliver more accurate end results, with higher-quality welds.
Experienced welders who have used a 1/1/1/1-rated helmet can immediately tell the difference in optical clarity. They report that they see better, the workpiece is clearer, and the experience is more comfortable than when they are wearing a helmet rated, for example, at 1/2/1/2. They see the arc without distortion in the higher-rated lens and notice clarity issues in the one that is rated lower. While we are talking about subtle parameters, professional welders can notice the difference between a 1 and a 2, and a huge difference between a 1 and a 3.
What’s more, optical clarity plays a role in welder productivity. If you’re looking through a distorted lens with impurities and inconsistent shade, your eyes will strain to see what you are doing, causing you to work harder. Viewing your welds through a clearer, better-quality lens will allow your eyes to work longer and also put less overall strain on your body.” – The Fabricator.com
