Welding Helmet Lens Shade Guide

Welding helmets are essential for protecting the welder's face and eyes from the harmful effects of welding. A welding helmet should have the right lens shade for the welding process and type of work being done. Choosing the correct lens shade is critical in ensuring that the welder is protected from the intense light and harmful radiation that is produced during the welding process. This guide provides information on welding helmet lens shades and how to choose the right one for your needs.

What is a Welding Helmet Lens Shade?

A welding helmet lens shade is a filter that is placed in the welding helmet's lens. The lens shade is designed to protect the welder's eyes from the intense light and harmful radiation produced during the welding process. Welding helmets come with lenses that are available in different shades, ranging from 4 to 14.

How to Choose the Right Lens Shade

Choosing the right lens shade depends on several factors, such as the welding process, amperage, and the type of metal being welded. The following are some of the factors to consider when choosing a welding helmet lens shade:

Welding Process

The welding process determines the level of brightness and radiation produced during the welding process. Different welding processes require different lens shades. For example:

• Shielded Metal Arc Welding (SMAW) or Stick welding typically requires a lens shade between 9 and 13.
• Gas Tungsten Arc Welding (GTAW) or TIG welding typically requires a lens shade between 8 and 13.
• Gas Metal Arc Welding (GMAW) or MIG welding typically requires a lens shade between 9 and 13.

Amperage

The amperage used during welding determines the brightness of the welding arc. Higher amperages produce brighter arcs that require darker lenses. For example:

• Less than 60 amps typically requires a lens shade between 7 and 9.
• 60 to 160 amps typically requires a lens shade between 9 and 10.
• 160 to 250 amps typically requires a lens shade between 10 and 12.
• More than 250 amps typically requires a lens shade between 12 and 14.

Type of Metal

The type of metal being welded also affects the brightness of the welding arc. Different types of metals require different lens shades. For example:

• Aluminum typically requires a lens shade between 9 and 11.
• Carbon steel typically requires a lens shade between 10 and 12.
• Stainless steel typically requires a lens shade between 10 and 12.

Conclusion

Choosing the right welding helmet lens shade is crucial for ensuring that the welder's eyes and face are protected from the intense light and harmful radiation produced during welding. Consider the welding process, amperage, and type of metal being welded when choosing a lens shade. By following these guidelines, you can ensure that you have the right lens shade for your welding needs.
