The Lincoln Electric Viking 3350 Twisted Metal (K3248-4) represents the 4th generation of the renowned 3350 series, engineered to provide professional welders with the highest standard of optical clarity and ergonomic comfort. This auto-darkening welding helmet integrates Lincoln’s proprietary 4C Lens Technology, which broadens the color range and hues visible in both light and dark states. By filtering out the traditional lime-green tint, the 4C technology delivers a true-color view of the arc, puddle, and base material, enhancing control and reducing eye strain during prolonged fabrication tasks.<\/p>\n
Optically, the K3248-4 achieves a perfect 1\/1\/1\/1 rating according to EN379 standards. This rating certifies that the lens excels in four critical categories: minimal blurriness, lack of distortion, consistent shade density, and uniform darkening at an angle. The helmet features an extra-large viewing area of 12.5 square inches (3.74 x 3.34 inches), providing an expansive field of view that increases situational awareness and safety. The auto-darkening filter (ADF) is powered by a replaceable CR2450 battery with solar assistance and utilizes four arc sensors to achieve a switching speed of 1\/25,000 of a second.<\/p>\n
Designed for industrial environments, the helmet includes an external low-profile grind button, allowing operators to switch between weld and grind modes without lifting the hood or removing gloves. This feature significantly improves productivity in high-throughput operations. The shell houses the innovative X6 Headgear, which contours to the operator’s head to distribute weight evenly across six key contact points, eliminating pressure hotspots and improving balance. The helmet is TIG rated for low-amperage applications (down to 2 Amps) and offers a variable shade range of 5-13, making it suitable for Stick, TIG, MIG, and Flux-Cored processes.<\/p>\n
