K4181-3 - Lincoln Electric VIKING 3350 Series Foose Impostor Auto-Darkening Hood

Premium Optical Clarity and Comfort

The Lincoln Electric VIKING™ 3350 Foose Impostor™ Welding Helmet (K4181-3) represents the pinnacle of welding safety technology and aesthetic design. Part of the renowned 3350 Series, this helmet is engineered to provide professional fabricators with an uncompromised visual experience. At the core of its performance is Lincoln's proprietary 4C® Lens Technology. This advanced filter formulation broadens the color range and hues that can be seen in both light and dark states, effectively eliminating the lime-green tint common in traditional auto-darkening filters. The result is a true-color view that reduces eye strain and allows for more precise weld placement.

The optical quality is further validated by its perfect 1/1/1/1 Optical Clarity rating according to EN379 standards. This rating certifies that the lens excels in four critical categories: blurriness, distortion, shade consistency, and angle uniformity. With a massive viewing area of 12.5 square inches (3.74" x 3.34"), operators have a full field of vision, increasing situational awareness and safety. The helmet features four independent arc sensors that ensure reliable switching from light to dark in 1/25,000 of a second, even when welding out of position or at very low amperages (down to 2 amps TIG).

Comfort is paramount for full-time welders, and the K4181-3 addresses this with the innovative X6 Headgear. This suspension system contours to the operator's head to distribute weight evenly across six key contact points, eliminating pressure spots and improving balance. The external grind button allows for seamless transitions between welding and grinding modes without removing the helmet or lifting the front, maintaining productivity and protection. The "Impostor" graphic, designed by legendary automotive designer Chip Foose, gives the helmet a unique, custom-painted appearance that stands out in any shop environment.
