K4034-3 - Lincoln Viking 3350 Code Red Auto-Darkening Helmet

Precision Optics for Professional Fabrication

The Lincoln Electric Viking 3350 Code Red (K4034-3) represents the pinnacle of welding helmet technology, designed specifically for professional fabricators who demand absolute precision. At the core of this helmet is Lincoln's proprietary 4C Lens Technology. Unlike traditional auto-darkening filters that cast a lime-green tint over the workpiece, 4C technology filters light to provide a true-color view. This results in a crystal-clear image of the arc, puddle, and base material, allowing for better control and reduced eye strain over long periods of use.

Technically, the Viking 3350 boasts a perfect 1/1/1/1 optical clarity rating according to the EN379 standard. This rating measures blurriness, distortion, shade consistency, and angle dependence. Achieving a perfect score in all four categories ensures that the welder sees the work exactly as it is, without the visual artifacts that can lead to weld defects. The helmet features a massive viewing area of 12.5 square inches (3.74" x 3.34"), one of the largest in its class, providing an expansive field of view that improves situational awareness and safety.

The K4034-3 is engineered for versatility across all welding processes. With a shade range of 5-13 and a TIG amp rating of greater than 2 amps, it is equally effective for heavy-duty MIG welding and delicate low-amp TIG applications. The helmet includes an external grind button, allowing operators to switch between weld and grind modes seamlessly without removing the helmet or lifting the hood. Powered by a solar cell with user-replaceable CR2450 lithium batteries, the Viking 3350 ensures reliable performance and longevity, backed by a 3-year warranty.
