CEP932-107-11 - Shade 11 Glass Welding Lens Filter Plate 4.5x5.25

Premium Optical Clarity for Industrial Welding

The Shade 11 Heat Treated Glass Filter Plate is an essential component for professional welders utilizing passive welding helmets with a large viewing area. Designed to fit standard 4-1/2 inch by 5-1/4 inch retaining systems, this filter plate provides a fixed level of darkness suitable for a wide range of medium-to-heavy amperage welding processes. Unlike auto-darkening filters (ADF), this passive glass lens offers zero switching time, ensuring that the welder's eyes are protected from the moment the arc is struck, provided the helmet is in the down position.

Manufactured from high-quality glass, this filter plate undergoes a rigorous heat-treatment process. This thermal hardening significantly increases the glass's resistance to thermal shock, preventing cracking or shattering under the intense heat fluctuations common in industrial welding environments. The glass material inherently provides superior optical properties compared to many polycarbonate alternatives, delivering a crisp, distortion-free view of the weld puddle. This clarity is critical for precision work where identifying the toe of the weld and monitoring fusion is paramount.

The Shade 11 rating is particularly effective for processes such as Shielded Metal Arc Welding (SMAW/Stick) and Gas Metal Arc Welding (MIG) at moderate amperage levels. It effectively filters out harmful Ultraviolet (UV) and Infrared (IR) radiation, protecting the operator from arc eye and long-term retinal damage. While glass is naturally more scratch-resistant than plastic, it is recommended to use this filter plate in conjunction with clear cover lenses (polycarbonate or glass) on both the front and rear to protect the filter from spatter, sparks, and impact.

For industrial facilities and MRO operations, stocking reliable, passive filter plates ensures that downtime is minimized. There are no batteries to replace, no sensors to fail, and no sensitivity settings to adjust. It is a pure, reliable barrier that performs consistently in harsh shop environments.
