CEP932-107-12 - 4.5 x 5.25 Inch Shade 12 Heat Treated Glass Welding Lens

Reliable Industrial Eye Protection

The Shade 12 Glass Filter Plate is a fundamental component for welders requiring reliable, fixed-shade protection. Measuring 4-1/2 inches by 5-1/4 inches, this lens is designed to fit standard large-view welding helmets and flip-front masks commonly used in industrial fabrication and maintenance. Manufactured from high-quality heat-treated glass, this filter plate offers exceptional thermal stability, ensuring it maintains its integrity even when subjected to the intense heat of prolonged welding operations.

Unlike polycarbonate alternatives, glass filter plates provide superior resistance to pitting and scratching, although they require careful handling to avoid breakage. The Shade 12 darkness level is specifically calibrated for medium-to-high amperage welding processes, effectively blocking harmful Ultraviolet (UV) and Infrared (IR) radiation. This ensures that the operator's eyes are protected against "arc eye" and long-term damage while maintaining a clear view of the arc and weld puddle.

At Josef Gas, we understand that clear vision is critical for quality welds. This passive filter plate delivers consistent optical clarity without the complexity of electronic auto-darkening filters. It is an economical and robust solution for workshops, manufacturing plants, and field repair crews. To maximize the lifespan of this filter plate, we strongly recommend installing it behind a clear polycarbonate cover lens to shield the glass from direct spatter impact.
