OVERVIEW

Comprehensive Protection for Your Welding Optics

The Lincoln CK31XX Replacement Lens Kit is an essential maintenance accessory designed to prolong the life of your welding helmet's auto-darkening filter (ADF). Welding environments are harsh, with constant exposure to high heat, molten spatter, and abrasive smoke particles. Over time, the protective cover lenses on your helmet can become pitted, scratched, or clouded, significantly reducing visibility and potentially compromising the integrity of the sensitive electronic filter behind them. This kit provides a complete solution for refreshing your helmet's optical path.

Manufactured from high-grade polycarbonate, these lenses offer superior impact resistance and optical clarity. The material is chosen for its ability to withstand the thermal and mechanical stresses typical of industrial welding applications while maintaining a lightweight profile. Regular replacement of cover lenses is a critical safety practice, ensuring that the welder always has a clear view of the weld pool, which is vital for achieving high-quality welds and maintaining safety standards.

This specific kit is tailored for the Lincoln CK31XX series helmets, ensuring a precise fit that seals out dust and fumes. The package includes a strategic mix of sizes to address common wear patterns: three large lenses, typically used for the front outer cover which takes the brunt of the spatter, and two small lenses, usually for the inner protection plate. This configuration allows for multiple replacements of the exterior shield while keeping a reserve for the interior, providing excellent value and operational readiness for professional fabricators.

FAQ

This kit is designed specifically for Lincoln CK31XX series welding helmets. Please verify your helmet model number before purchasing to ensure proper fitment.

The package contains a total of 5 lenses: 3 large lenses (typically for the outer cover) and 2 small lenses (typically for the inner cover).

These lenses are manufactured from high-quality polycarbonate, which offers excellent impact resistance and optical clarity.

Welding helmets typically use a larger outer lens to protect the ADF from spatter and a smaller inner lens to protect it from dust and moisture. This kit provides replacements for both.

You should replace your cover lenses whenever they become pitted, scratched, or too dirty to clean effectively. A damaged lens can obscure your vision and reduce weld quality.

While polycarbonate naturally blocks some UV, the primary UV/IR protection is provided by the auto-darkening filter itself. These clear lenses serve as a physical barrier to protect the ADF.

Yes, the polycarbonate material is impact-resistant and suitable for protecting the ADF during grinding operations, provided the helmet is rated for such use.

These lenses are dimensioned for the CK31XX series. Other Lincoln helmets (like the Viking series) use different lens sizes, so they are likely not interchangeable.
