When looking at your work through a welding hood, it’s sometimes necessary for the lens to be less dark so that you can see what’s in front of you. Nothing would feel more hectic than flipping the helmet every time you need to see.
While exposed to something as bright as a weld, an auto darkening lens gets darken, but the glass will remain lighter when performing tasks such as grinding. They enable you to work in a more secure environment.
That’s why auto darkening welding lenses are the best accessory for welding. Among the various sizes, 2X4 is the most convenient as it’s suitable for almost all types of welding tasks.

How To Choose The Best 2X4 Auto Darkening Welding Lens?
After going through the best auto darkening welding lenses and knowing how they work, you need to know what factors to consider before buying one. So, go through this guide to learn all about them!
The shade of your welding lens should be compatible with the type of welding. Not all the lenses are suitable for all welding tasks. For example, shade 9-13 is ideal for TIG and Stick welding. For MIG welding, the shade should be 10-13. So, if your welding lens can’t provide enough level of shade, it’ll serve no purpose to offer you protection.
The environment where you work plays a significant role in choosing your welding equipment. If you’re working at home on DIY projects, you can select a welding lens that comes with the basic features.
But, if you need to work outside, make sure to choose a welding lens that has resistance against moisture and dust. For pipeline welding, the lens has to be highly durable and endure adverse environments.
It’s an essential factor to consider as you’ll be seeing through this space. The wider this space is, the more convenient it will be for you.
If you choose a welding lens with a small viewing area, you’ll have to move your head a lot to see correctly. Your peripheral vision won’t work as well since most of your vision is blocked. On the other hand, if you go for a wider viewing area, you can see adequately without even moving your head now and then.
Try to buy a welding lens that has a viewing area of at least 4.25 inches or more. Anything less than that wouldn’t be convenient.
Mode for Grinding
When you are just grinding, you don’t need your welding lens to get dark. Instead, you need to be able to see appropriately to make sure you’re doing your work in a precise manner. This is why the welding lens you choose should have a grinding mode so that it can go light when you’re not welding. Otherwise, you’ll have to remove the helmet every time you stop working with the arc.
Fixed or Adjustable Shade
Auto darkening welding lenses are available in certain levels of shades. Some of them are fixed, some of them are adjustable. Fixed shades come with one level of shade only.
For example, if you buy a fixed shade 11 welding lens, it’ll turn to shade 11 from a lighter state every time you weld. But, if you buy a lens with an adjustable shade, the lens will adjust the shade based on the light created by the welding task.
For example, a welding lens with adjustable shade 9-13 can provide different levels of shade. Its arc sensors can detect the light and respond accordingly to create the level of shade.
Design and Weight
The welding lens you choose should be compact and lightweight. Otherwise, it might not fit on a lot of welding helmets. Also, if the lens weighs too much, it’ll increase the overall weight of the helmet. The welding helmet weighs a lot, so you wouldn’t want the weight to increase even more!
The purpose of an auto darkening welding lens is to protect you from arc hazards. But, you need to be able to see properly while you’re welding as well. So, if the lens doesn’t provide clear vision, you won’t be able to see how you’re performing and may end up ruining the work. So, it’s best to go for a welding lens with an HD display that’ll offer the best clarity.
Tinted or True Color
Welding lenses are available in a lot of variations. Some of them are tinted, while the others provide a true image. What you should choose between these two depends on your preference. If you prefer to have the actual true color saturation, go for the ones that aren’t tinted. And if you like blue-tinted lenses that block out orange and green color spectrums, go for the lenses that have clear blue technology.
Finally, price is a significant factor to consider if you’re on a budget. Good quality auto darkening welding lenses will cost a bit more than the regular ones. But, you have to consider the features it provides against the price range. If you find a better alternative within the same price range, go for the second one and save some money.
Also, consider the features that you need. If you’re not a pipeline welder, you don’t need a welding lens that’s highly durable and more expensive. Medium range welding lenses would be sufficient to use at home and in workshops.
How Auto Darkening Welding Lenses Work?
Auto darkening welding lenses are equipped with a filter for interference. Its job is to block infrared and ultraviolet radiation. There are three more filters for polarization placed in front of the initial filter. The polarization filters work just like sunglasses. When they detect that light is passing through them, they get darker.
These combined sets of filters can absorb more than 99.99% of UV radiation. The layers of metal and glass can reflect more than 99.99% infrared light. When the welding lens isn’t on, they’re in this state like a sunglass.
Now, these filters also have LC or liquid crystal cells in them. When the light goes through them, the crystal cells bend it.
When you turn the welding lens on, the crystal cells start to work. The more light passes through them, the darker they get to bend the light away, which turns into a dark tint.
If any of the filters or LC cells in this set don’t work, the entire welding lens will lose its efficiency, and you need to replace it with a new one.
