K4671-4 - Lincoln Viking 3350 Medieval 4th Gen Auto-Darkening Helmet

Lincoln Electric Viking 3350 Medieval Welding Helmet (Gen 4)

The Lincoln Electric Viking 3350 Medieval Welding Helmet (K4671-4) represents the pinnacle of the 3350 Series, now in its 4th Generation. Engineered for the professional fabricator who demands precision, this helmet integrates Lincoln's proprietary 4C Lens Technology. This advanced liquid crystal display (LCD) optimizes the visible light spectrum, broadening the color range and hues available in both light and dark states. The result is a perfect 1/1/1/1 Optical Clarity rating, which eliminates common lens imperfections such as blurriness, distortion, and shade inconsistency. By removing the traditional lime-green tint found in older ADFs, the 4C technology provides a true-color view of the arc, puddle, and base material, significantly reducing eye strain during prolonged welding sessions.

The K4671-4 is designed with a massive 12.5 square inch viewing area (3.74 x 3.34 inches), offering one of the largest fields of view in its class. This expanded visibility enhances operator control and safety by allowing for better peripheral vision. The helmet is equipped with four independent arc sensors and boasts a switching speed of 1/25,000 of a second, ensuring immediate protection the moment an arc is struck. It features a versatile variable shade range of 5-13, making it suitable for Stick, TIG, MIG, and Flux-Cored processes. The low TIG amp rating of 2 Amps ensures stable lens performance even during precision low-amperage TIG applications.

Comfort and ergonomics are addressed with the innovative X6 Headgear. This system contours to the operator's head, distributing weight evenly across six key contact points to eliminate pressure hotspots and improve balance. The helmet also features a low-profile external grind button, allowing welders to switch seamlessly between weld and grind modes without removing the helmet or gloves, thereby maximizing productivity. Powered by a combination of solar cells and a replaceable CR2450 battery, the Viking 3350 ensures reliable performance and long service life. This model comes with the distinctive "Medieval" graphic shell, adding a unique aesthetic to its industrial-grade protection.
