K3371-1 - Lincoln VIKING Industrial Passive Fixed Shade 11 Helmet

Reliable Passive Protection for Industrial Applications

The Lincoln Electric VIKING™ Industrial Passive™ Black Welding Helmet (K3371-1) is engineered to provide robust, consistent optical protection for professional welders and students alike. Unlike auto-darkening filters, this helmet utilizes a fixed Shade 11 lens, offering immediate and constant shielding against harmful UV and IR radiation generated during the welding arc. The passive design eliminates the need for batteries or sensors, ensuring operational readiness at all times. This model is particularly well-suited for educational environments, general fabrication, and maintenance tasks where a high-value, low-maintenance solution is required.

Constructed from a durable thermoplastic shell, the helmet is designed to withstand the rigors of daily industrial use while maintaining a lightweight profile of approximately 19.8 ounces. This reduction in weight minimizes neck strain during prolonged welding sessions, enhancing operator comfort. The shell features a matte black finish, providing a sleek, professional appearance that resists reflection. Included with the helmet is a decal sheet, allowing users to customize the exterior to their preference.

The optical system features a generous 4" x 5" viewing area, significantly larger than many standard passive helmets. This expanded field of view improves situational awareness and weld puddle control. The helmet comes equipped with a ratchet-style headgear that offers multiple adjustment points, ensuring a secure and personalized fit for various head sizes. Compliance with ANSI Z87.1 and CSA Z94.3 standards guarantees that the equipment meets rigorous safety performance criteria for impact resistance and optical quality.

Versatility is a key component of the K3371-1. It is rated for a wide range of welding processes, including Stick, TIG, Pulsed TIG, MIG, Pulsed MIG, Flux-Cored, and Gouging. While it excels in flat and horizontal positions, operators should note specific manufacturer guidelines regarding overhead welding suitability. The simplicity of the passive lens system combined with Lincoln Electric's manufacturing quality makes this an ideal choice for those seeking a "back-to-basics" approach to personal protective equipment without compromising on safety or durability.
