K3034-3 - Lincoln Viking 3350 Series Black Welding Helmet with 4C Technology

Technical Overview of the Lincoln Viking 3350 (K3034-3)

The Lincoln Electric Viking 3350 Series, specifically the K3034-3 Black model, represents a significant advancement in auto-darkening filtration technology. This unit is defined by its integration of proprietary 4C Lens Technology, which stands for Clarity, Color, Carat, and Cut. Technically, this results in a lens that achieves a perfect 1/1/1/1 Optical Clarity rating according to EN379 standards. This rating certifies that the lens is free from blur, distortion, and inconsistent shading at any angle, providing the welder with a technically superior view of the arc and base material.

The ADF (Auto-Darkening Filter) cartridge features an expansive viewing area of 3.74 x 3.34 inches (approximately 12.5 square inches), one of the largest in the industrial sector. The switching mechanism is driven by four independent arc sensors, ensuring rapid detection of the arc in 1/25,000 of a second, even in obstructed environments or low-amperage TIG applications. The helmet is rated for TIG welding at less than 2 Amps, making it suitable for precision aerospace and thin-gauge fabrication. The shade range is variable from DIN 5 to 13, with internal controls for sensitivity and delay, allowing for fine-tuning based on ambient lighting and welding process currents.

Power is managed through a hybrid system utilizing solar cells for primary operation during welding, supplemented by a user-replaceable CR2450 lithium battery to ensure instant startup and consistent performance. The shell is constructed from high-impact nylon, designed to withstand industrial environments while maintaining a relatively low weight of approximately 21 ounces (595g). The K3034-3 also features an external grind button, allowing operators to switch to a clear state without lifting the helmet or removing gloves, thereby maintaining safety compliance and workflow efficiency.
