3M 7010385033 Cover Lens Shade 12 Inside Mount 2-pack

Product Description

The 3M 7010385033 is a shade 12 cover lens designed for use with the 3M Speedglas 9100 series welding helmet. Constructed from a nylon and polycarbonate composite, this inside-mount lens protects the auto-darkening filter (ADF) cartridge from weld spatter, arc flash, and debris accumulation. The lens measures 7.112 inches in height and 10.668 inches in width, providing full-coverage protection across the viewing window. Sold in a 2-pack, it is intended for periodic replacement as part of routine helmet maintenance. Welding technicians across MIG, TIG, stick, and plasma cutting applications rely on clear cover lenses to maintain unobstructed sight lines during operation.

This cover lens is suited for professional welding environments in both residential fabrication shops and heavy industrial settings. The inside mount design positions the lens on the interior face of the ADF, shielding the filter from fine spatter and smoke particulate that can reduce optical clarity over time. Regular replacement is standard practice for technicians performing high-duty-cycle work. The shade 12 rating aligns with the lens to the optical protection level of the 9100 series helmet system.
