932-108-10 - 4x5 Shade 10 Polycarbonate Welding Lens Filter Plate

Industrial Grade Passive Protection

The Lense Filter Plate Shade 10 4X5 Plastic is an essential consumable for welding professionals utilizing passive, fixed-shade helmets. Designed to fit standard large-window welding hoods, this filter plate measures nominally 4.5 inches by 5.25 inches, providing a wide field of view that enhances situational awareness and weld puddle control. Unlike traditional glass filter plates, this unit is manufactured from high-grade optical polycarbonate. This material choice offers superior impact resistance, meeting rigorous industrial safety standards for face and eye protection against flying debris and sparks.

In industrial MRO environments, equipment durability and operator safety are paramount. The polycarbonate construction of this filter plate ensures that it will not shatter upon impact, a critical safety feature compared to hardened glass alternatives. Furthermore, the Shade 10 darkness level is the industry standard for a wide variety of welding processes, including Shielded Metal Arc Welding (SMAW) and Gas Metal Arc Welding (GMAW) at moderate amperage levels. It effectively filters out harmful Ultraviolet (UV) and Infrared (IR) radiation, preventing arc eye and long-term retinal damage.

Weight reduction is another key technical advantage of this product. For welders operating for extended periods, every ounce of weight on the headgear contributes to neck strain and fatigue. This plastic filter plate is significantly lighter than its glass counterparts, contributing to better ergonomics and sustained productivity. It is designed to be used in conjunction with a clear cover lens (polycarbonate) on both the front and rear to protect the filter itself from spatter and scratching, ensuring a long service life in demanding fabrication shops.

This replacement lens is compatible with most major brands of welding helmets that accept a 4.5" x 5.25" retention system. It is an ideal stock item for tool cribs and safety supply inventories, ensuring that downtime is minimized when a lens needs replacement due to pitting or excessive scratching.
