KP3283-1 - Lincoln Viking 1740 Replacement Inside Clear Lens (5-Pack)

Precision Protection for Your Viking 1740 ADF

The Lincoln Electric KP3283-1 Inside Clear Cover Lens Kit is a critical maintenance component designed exclusively for the Viking 1740 Series welding helmets. This kit contains five high-quality replacement lenses engineered to protect the internal surface of your helmet's Auto-Darkening Filter (ADF). While the outer lens takes the brunt of sparks and spatter, the inside lens is equally vital, shielding the sophisticated electronics of the ADF from dust, moisture, sweat, and potential scratching during cleaning or handling.

Manufactured to precise specifications, each lens measures 95.9 x 47.2 x 1.0 mm (3.78 x 1.86 x 0.04 in.). This exact sizing ensures a dust-tight seal within the helmet assembly, preventing particulate matter from compromising the optical path. Using non-OEM or ill-fitting generic lenses can lead to gaps that allow debris to settle on the ADF glass, potentially causing permanent damage to the filter itself. The KP3283-1 is made from durable, optical-grade material that maintains the high clarity rating of the Viking 1740 series, ensuring that the welder's view remains undistorted and sharp.

Regular replacement of the inside cover lens is a standard procedure in industrial welding environments. Over time, even inside lenses can become cloudy due to off-gassing, fine particulate accumulation, or micro-abrasions from wiping. By maintaining a fresh inside lens, operators ensure that the high-definition optics of the Viking 1740 are utilized to their full potential. This 5-pack configuration provides an economical solution for workshops and individual welders, ensuring a replacement is always on hand when visibility begins to degrade.

Technical Specifications

The lenses are designed to be easily swapped out. The retention system in the Viking 1740 allows for quick changes without the need for complex tools, minimizing downtime. As a genuine Lincoln Electric part, the KP3283-1 guarantees compatibility and performance consistency. It is important to note that these lenses are specific to the 1740 chassis and will not fit the 1840, 2450, or 3350 series helmets.
