Outer Lens 3M Speedglas Standard 140x85 mm, 10-pack for Welding Mask 100

Replacement outer lens for the 3M Speedglas welding mask 100. This standard clear protective lens measures 140 x 85 mm and is supplied in a pack of 10. It is designed to shield the auto-darkening filter from spatter, scratches and contamination while maintaining optical clarity. The thin, transparent cover preserves the viewing area and helps extend the service life of the helmet’s internal filter for professional and hobby welding tasks.

Advantages

The outer lens provides a clear protective barrier that reduces the need for frequent cleaning of the auto-darkening filter and minimizes surface damage from welding spatter. Its standard dimensions ensure compatibility with the Speedglas 100 viewing window, and the pack quantity offers convenient spare parts for repeated replacements. Lightweight and easy to handle, the lens does not interfere with the optical performance of the helmet and supports uninterrupted visibility during welding.
