03IP-1 - Walter ArcOne 03IP-1 Passive 2x4 Welding Lens Shade 10 Upgrade

High-Performance Passive Welding Filter

The Walter 03IP-1 Passive 2x4 Shade 10 Upgrade is a premium replacement filter designed for professional welding helmets requiring a standard 2-inch by 4.25-inch lens. Manufactured under the Walter Surface Technologies umbrella (incorporating ArcOne technology), this lens is engineered to provide exceptional optical clarity and consistent protection against harmful UV and IR radiation. As a passive filter, it maintains a fixed shade state, making it an ideal choice for welders who prioritize optical purity and reliability over variable shading features.

This lens is specifically calibrated to Shade 10, a versatile darkness level suitable for a broad spectrum of welding processes, including Stick (SMAW) and MIG (GMAW) at moderate amperages. The lens construction utilizes high-grade optical materials to minimize distortion and reduce eye strain during prolonged use. Its standard dimensions ensure compatibility with the vast majority of 'pancake' style hoods, pipeline helmets, and traditional flip-front welding masks found in industrial environments.

In MRO and fabrication settings, the reliability of a passive lens cannot be overstated. With no electronics to fail, no batteries to replace, and no sensors to obstruct, the 03IP-1 ensures that the welder is always protected the moment the arc is struck. It serves as an excellent primary lens for dedicated applications or as a robust backup for auto-darkening systems. The upgrade designation implies a focus on superior visual acuity compared to standard economy filters.
