1/1/1/1 or 1/1/1/2 welding lens

When it comes to welding, safety and precision are of utmost importance. This is where the optical class 1/1/1/1 auto darkening welding filter comes into play. The optical class rating of 1/1/1/1 signifies the highest level of optical quality in terms of clarity, distortion, consistency, and angle dependence. This means that the 1/1/1/1 or 1/1/1/2 welding lens provides the clearest and most accurate view of the welding area, allowing for precise and efficient work. This advanced technology offers top-notch protection for welders.

The meaning of 1/1/1/1 or 1/1/1/2

1. Optical class 3/X/X/X V.S. 1/X/X/X




You know how distorted something can look through water?  That's what this class is all about. It rates the level of distortion when looking through the auto dark welding lens, with 3 being like looking through rippled water, and 1 being next to zero distortion - practically perfect

2. Diffusion of light class      X/3/X/X V.S. X/1/X/X




When you're looking through an auto dark welding lens for hours at a time, the tiniest scratch or chip can have a big impact. This class rates the welding filter for any manufacturing imperfections. Any top-rated auto dark welding lens can be expected to have a rating of 1, meaning it is free of impurities and exceptionally clear.

3. Variations in luminous transmittance class (light or dark areas within the lens)

X/X/3/X V.S. X/X/1/X




Auto dark welding lens typically offer shade adjustments between #4 - #13, with #9 being the minimum for welding. This class rates the consistency of shade across different points of the welding filter. Basically you want the shade to have a consistent level from top to bottom, left to right. A level 1 will deliver an even shade throughout the entire welding filter, where a 2 or 3 will have variations at different points on the welding filter, potentially leaving some areas too bright or too dark.

4. Angle dependence on luminous transmittance X/X/X/3 V.S. X/X/X/1




This class rates the auto dark welding lens for its ability to provide a consistent level of shade when viewed at an angle (because we don't just weld stuff that's directly in front of us). So this rating is particularly important for anyone welding those hard to reach areas. It tests for a clear view without stretching, dark areas, blurriness, or issues with viewing objects at an angle. A 1 rating means the shade stays consistent no matter the viewing angle.

Tynoweld 1/1/1/1 and 1/1/1/2 welding lens

Tynoweld has 1/1/1/1 or 1/1/1/2 welding lenses with various view sizes.

1.108*51mm TC108 series

The 2 x 4 welding lens is a standard size that fits most American welding helmets. It offers a clear view of the welding area while providing protection from harmful UV and infrared rays.


2.Mid-View Size auto dark welding filter (110*90*9mm Filter dimension with view size 92*42mm / 98*45mm / 100*52mm / 100*60mm)

In recent years, auto-darkening welding lenses have become increasingly popular due to their convenience and effectiveness. Among the various options available, mid-view size auto-darkening welding lenses offer several advantages that make them a preferred choice for many welders. Mid-view size auto-darkening welding lenses offer a comfortable and ergonomic design. The mid-view size welding lens provides adequate coverage without being too bulky or obstructive, allowing for greater freedom of movement and flexibility during welding tasks. This can significantly reduce the strain on the neck and head, leading to improved comfort and reduced fatigue during prolonged welding sessions.


3.Big-View Size auto dark welding filter (114*133*10 Filter dimension with view size 91*60mm / 100*62mm / 98*88mm)

The Big view size auto-darkening welding filter, as the name suggests, offers a larger viewing area compared to the mid-view size auto dark welding filter. This larger viewing area provides welders with a wider field of vision, allowing them to see more of their workpiece and the surrounding environment. This can be particularly beneficial when working on larger projects or when a greater level of visibility is required.
