The Walter Surface Technologies (ArcOne) S540-9 is a high-quality passive welding filter plate designed for industrial safety and performance. This lens features a fixed Shade 9 darkness level, making it appropriate for specific welding applications where moderate arc brightness is generated, such as low-amperage TIG or MIG welding. The lens is manufactured from optical-grade polycarbonate, a material chosen for its superior strength-to-weight ratio compared to traditional hardened glass.
The dimensions of this filter plate are the industry-standard "large view" size, technically measuring 4.5 inches by 5.25 inches (often colloquially referred to as 5x4). This ensures compatibility with a wide range of passive welding helmets and hoods from various manufacturers that accept standard large-format retaining systems. Unlike auto-darkening filters, this passive lens provides a constant level of protection, ensuring that ultraviolet (UV) and infrared (IR) radiation are blocked at all times, regardless of whether the arc is struck.
The S540-9 is engineered to meet rigorous safety standards. The polycarbonate construction offers significant impact resistance, meeting ANSI Z87.1 standards for high-velocity impact protection. This makes it a safer choice in environments where grinding debris or accidental drops might shatter a glass lens. Despite its durability, the lens maintains high optical clarity to allow for precise weld puddle manipulation. It is designed to be used in conjunction with clear cover lenses (front and rear) to protect the filter itself from pitting and smoke residue.
