K3255-4 - Lincoln VIKING 3350 Gen 4 Auto-Darkening Helmet Polar Arc Graphic

Industry-Leading Optics and Professional Performance

The Lincoln Electric VIKING 3350 Polar Arc Welding Helmet (4th Generation) represents the pinnacle of protective eyewear technology for professional fabricators. Engineered to provide the clearest possible view of the weld puddle, this helmet integrates Lincoln's proprietary 4C Lens Technology. This advanced liquid crystal display (LCD) broadens the visible color spectrum, eliminating the traditional lime-green tint found in older auto-darkening filters. The result is a True Color view that reduces eye strain and allows for precise control over the arc. With a perfect 1/1/1/1 optical clarity rating—measured against blurriness, distortion, shade consistency, and angle uniformity—welders can trust that what they see is exactly what is happening at the joint.

Productivity is a core focus of the Gen 4 design. The helmet features a low-profile external grind button, allowing operators to switch seamlessly between welding and grinding modes without removing the helmet or gloves. This significantly reduces downtime during prep and finish work. The auto-darkening filter (ADF) offers a massive 12.5 square inch viewing area (3.74 x 3.34 inches), one of the largest in its class, providing excellent peripheral vision and situational awareness. The lens is capable of variable shading from DIN 5 to 13, making it suitable for a wide range of processes including Stick, MIG, Pulsed MIG, TIG, and Flux-Cored welding.

Comfort is critical for long shifts, and the VIKING 3350 addresses this with the innovative X6 Headgear. This suspension system contours to the operator's head using six key contact points to evenly distribute weight and eliminate pressure hotspots. The helmet is also designed for outdoor performance, utilizing technology that differentiates between the welding arc and sunlight to prevent false darkening. Powered by a combination of solar cells and a replaceable CR2450 battery, and backed by an industry-leading 5-year warranty, the K3255-4 is a robust investment for serious welders.
