CEP932-107-9 - Shade 9 Glass Welding Filter Plate 4.5 x 5.25 Inch

Precision Optics for Industrial Welding

The Shade 9 Heat Treated Glass Filter Plate is a premium passive welding lens designed for professionals who demand superior optical clarity and thermal durability. Measuring a standard 4 1/2 inches by 5 1/4 inches, this filter plate is engineered to fit a wide range of industrial welding helmets and fixed-shade hoods that accommodate large-format lenses. Unlike polycarbonate alternatives, heat-treated glass provides a stable, distortion-free viewing area that maintains its integrity even under high thermal stress.

Optical Clarity and Performance

Glass filter plates are renowned in the industry for their scratch resistance and exceptional visual acuity. This Shade 9 lens is ideal for lower amperage welding applications where a lighter shade is required to maintain visibility of the arc and puddle without compromising eye safety. It effectively filters harmful Ultraviolet (UV) and Infrared (IR) radiation, protecting the welder's eyes during TIG, MIG, or Stick welding operations. The heat-treatment process significantly increases the impact resistance of the glass, ensuring it meets rigorous safety standards for industrial environments.

Application and Compatibility

This filter plate is a universal replacement for standard 4x5 openings. It is particularly well-suited for fabrication shops, maintenance departments, and manufacturing facilities where fixed-shade helmets are preferred for their reliability and lack of electronics. To maximize the lifespan of this filter plate, it is strongly recommended to use it in conjunction with clear polycarbonate cover lenses on both the front and rear. This setup protects the precision glass from spatter, pitting, and smoke residue, ensuring long-term performance and cost-effectiveness.
