KP3043-1 - Lincoln Viking 1740/1840 Outside Cover Lens (5-Pack)

Maintain Optical Clarity with Lincoln Electric KP3043-1

The Lincoln Electric KP3043-1 Outside Cover Lens is a critical consumable for professional welders utilizing the Viking 1740 and 1840 Series welding helmets. Designed to serve as the first line of defense for your helmet's high-tech Auto-Darkening Filter (ADF), this clear cover lens shields the expensive optics from molten spatter, high-velocity debris, smoke residue, and scratches that occur during standard welding operations. Maintaining a pristine outer lens is essential not only for protecting your equipment investment but also for ensuring the visual precision required for high-quality welds.

Manufactured from high-grade polycarbonate, these lenses offer superior impact resistance, meeting rigorous ANSI Z87.1 and CSA Z94.3 safety standards. The material is selected for its optical purity, ensuring that there is no distortion or cloudiness that could impede the welder's view of the puddle. With precise dimensions of 114 x 100 x 1.0 mm (4.5 x 3.94 x 0.04 in.), the KP3043-1 provides a perfect seal against the helmet shell, preventing particulate matter from bypassing the lens and damaging the ADF unit behind it.

Regular replacement of the outside cover lens is a standard maintenance procedure that significantly improves weld quality. A pitted or dirty lens diffuses light, causing glare and reducing contrast, which can lead to eye strain and errors in bead placement. This package contains five (5) replacement lenses, allowing industrial facilities and independent fabricators to keep a ready stock of consumables. By ensuring your Viking 1740 or 1840 helmet is always equipped with a fresh cover lens, you maintain the high-definition view these helmets are known for, ultimately contributing to safer and more efficient welding operations.

Compatibility Note: These lenses are specifically engineered for the Viking 1740 and 1840 series shells. They are not compatible with the Viking 3350, 2450, or other helmet models. Please verify your helmet series before purchasing to ensure proper fitment and protection.
