CEP932-107-5 - Shade 5 Glass Welding Lens 4.5x5.25 Heat Treated

High-Quality Heat Treated Glass Filter Plate – Shade 5

The Shade 5 Glass Filter Plate (4.5" x 5.25") is a premium passive welding lens designed for optimal optical clarity and thermal resistance. Manufactured from high-grade glass, this filter plate undergoes a rigorous heat-treatment process to enhance its durability and resistance to thermal shock. Unlike polycarbonate alternatives, glass lenses offer superior scratch resistance and maintain their optical properties over extended periods of use, provided they are protected from severe impact.

This specific lens is calibrated to Shade 5, making it the industry standard for oxy-fuel cutting, brazing, and light gas welding applications. It effectively filters harmful ultraviolet (UV) and infrared (IR) radiation generated during these processes while providing a clear, high-contrast view of the weld puddle or cut line. The 4.5-inch by 5.25-inch dimensions fit standard "large window" welding helmets and goggles that accommodate this specific form factor.

Professionals in the MRO and fabrication sectors rely on heat-treated glass for its stability. While heavier than plastic, the thermal mass of glass helps resist warping in high-heat environments. This lens is intended to be used in conjunction with clear cover lenses (polycarbonate or glass) on both the front and rear to protect the filter from spatter and impact damage, ensuring a long service life and compliance with safety standards.
