OVERVIEW

Professional Clarity and Comfort

The Lincoln Electric VIKING™ 1740 Ignition™ Welding Helmet (K4375-2) is engineered to provide professional-grade optical performance in an economical package. This helmet is part of the 1740 Series, which is renowned for bridging the gap between entry-level safety gear and premium industrial equipment. The standout feature is the integration of Lincoln's proprietary 4C® Lens Technology. Unlike traditional auto-darkening filters that impart a lime-green tint, 4C technology broadens the color range and hues that can be seen in both light and dark states. This results in a view that is clearer, crisper, and more natural, allowing for better control over the weld puddle.

With a perfect 1/1/1/1 optical clarity rating according to EN379 standards, the lens eliminates blur, distortion, and inconsistent shading. This level of precision is critical for welders performing intricate TIG work or long-duration MIG fabrication where eye strain can become a significant fatigue factor. The viewing area measures 6.3 square inches (3.78 x 1.67 inches), providing ample visibility of the workpiece and surrounding area.

Operational Efficiency

The 1740 Ignition is designed for versatility across welding processes, including Stick, TIG, and MIG. It features a variable shade range of DIN 9-13, easily adjustable via an internal dial. Sensitivity and delay settings allow the user to tailor the lens response to the specific environment, ensuring the lens stays dark during low-amp TIG welding (rated down to 5 Amps) or clears quickly during tack welding. The helmet is powered by a solar cell assisted by two user-replaceable AAA batteries, ensuring long service life and reliability.

Weighing in at approximately 18.6 oz (528 g), the shell is lightweight yet durable, designed to accommodate a cheater lens if necessary. The included ratchet headgear allows for fore/aft adjustments to optimize balance and comfort. The "Ignition" graphic provides a modern, industrial aesthetic that stands out in the shop.
