20. Dark Lense 9 10 11

A dark lens in a welding helmet is an essential piece of safety equipment that protects the welder's eyes from the harmful ultraviolet (UV) and infrared (IR) radiation emitted during the welding process. The dark lens filters out this radiation, preventing it from reaching the eyes and causing damage.

The shade of the dark lens required for welding depends on the type of welding being done and the welding machine being used. For most welding applications, a shade 9 or 10 lens is sufficient. However, for more intense welding, such as welding with a large amperage machine, a darker shade, such as 11 or 12, may be necessary.

It is important to choose the correct shade of dark lens for the welding application to ensure the welder's eyes are properly protected. Using a lens that is too dark can make it difficult to see the weld pool, while using a lens that is too light can allow harmful radiation to reach the eyes.

Here are some additional things to keep in mind when choosing a dark lens for a welding helmet:

• The lens should be made of a high-quality material that is resistant to scratches and breakage.
• The lens should have a wide field of view so that the welder can see the entire weld area.
• The lens should be comfortable to wear, even for extended periods of time.

By choosing the right dark lens for a welding helmet, welders can protect their eyes from the harmful radiation emitted during the welding process and help prevent eye injuries.

Here are some of the benefits of using a dark lens in a welding helmet:

• Protects the eyes from harmful UV and IR radiation.
• Improves visibility of the weld pool.
• Reduces eye fatigue.
• Helps prevent eye injuries.
