K3023-1 - Lincoln Viking 1840 Black Auto-Darkening Welding Helmet

Technical Precision and Optical Excellence

The Lincoln Electric Viking 1840 Series (K3023-1) represents a significant step forward in personal protective equipment for industrial applications. Engineered to meet the rigorous demands of professional fabrication, this helmet is distinguished by its perfect 1/1/1/1 optical clarity rating according to EN379 standards. This rating ensures that the welder experiences no blurring, distortion, or artificial coloring of the weld puddle, allowing for precise bead placement and superior weld quality control. The auto-darkening filter (ADF) features a viewing area of 3.78 x 1.89 inches (96 x 48 mm), providing a focused field of view that is optimal for general fabrication and production welding.

The K3023-1 is designed with a specific focus on ergonomics and spatial efficiency. The shell geometry is notably compact, reducing the overall profile of the user. This design choice makes the 1840 Series particularly effective for applications involving confined spaces, pipe welding, or complex structural assemblies where head clearance is limited. Despite its robust protection, the helmet weighs approximately 18 ounces (510 grams), significantly reducing the torque and strain placed on the operator's neck muscles during extended shifts. The suspension system utilizes a pivot-style headgear that distributes weight evenly, further enhancing stability and comfort.

Functionally, the helmet is equipped with two independent arc sensors that provide reliable arc detection even in obstructed environments. The lens switching speed is rated at 1/25,000 of a second, ensuring immediate protection from harmful UV and IR radiation upon arc ignition. The shade range is variable from DIN 9 to 13, accommodating a wide spectrum of welding processes including Stick, TIG, MIG, and Flux-Cored. A critical feature for productivity is the external grind mode control, which allows the operator to switch between welding and grinding states without removing the helmet or lifting the front cover. The unit is powered by a solar cell assisted by a user-replaceable CR2450 lithium battery, ensuring long operational life and reliability.
