04-OP - ArcOne 04-OP Polycarbonate Replacement Lens 110x90mm

High-Performance Protection for Welding Optics

The ArcOne 04-OP 110 x 90 mm Cover Plate is a critical component designed to safeguard the integrity of auto-darkening filters (ADF) and passive welding lenses. Manufactured from high-grade polycarbonate, this cover plate offers superior impact resistance and optical clarity, ensuring that the welder's vision remains unobstructed during complex fabrication tasks. With precise dimensions of 110 mm in width, 90 mm in height, and a thickness of 1 mm, this lens is engineered to meet rigorous industrial standards for fit and function.

Polycarbonate is the material of choice for welding cover plates due to its exceptional strength-to-weight ratio and thermal stability. Unlike standard plastic or glass, polycarbonate can withstand high-velocity impact from grinding particles and the intense heat generated by welding arcs without shattering. This specific plate, the 04-OP, serves a dual purpose depending on the helmet configuration. It functions as an outside cover plate for standard welding helmets requiring a 90x110 mm lens, taking the brunt of welding spatter, sparks, and radiant heat. Simultaneously, it is specified as the inside cover plate for specific ArcOne helmet models, including the X54V, X54Vi, and X81VX series. In the inside position, it protects the rear of the ADF from dust, sweat, and potential scratches during handling.

Maintaining the optical path is essential for weld quality. A pitted or scratched cover plate diffuses light, causing glare and reducing contrast, which can lead to weld defects. The ArcOne 04-OP provides a pristine, clear barrier that preserves the optical class of the underlying filter. Its 1 mm thickness ensures it is rigid enough to stay flat in the retaining frame, preventing distortion, yet flexible enough to withstand thermal expansion. Regular replacement of these consumables is a standard maintenance procedure that prolongs the lifespan of the significantly more expensive ADF unit.

Industrial safety managers and procurement specialists should note the versatility of this SKU. By stocking the 04-OP, facilities can support multiple helmet types—both generic 90x110 mm shells and specific ArcOne high-performance units—simplifying inventory management. The lens is supplied clear, ready for immediate installation, and is compatible with standard cleaning protocols for polycarbonate surfaces.
