The assembly comes fully equipped with the helmet shell, the high-performance auto-darkening lens, premium headgear, a protective head covering, and the integrated air duct system.

Superior Vision with 4C Technology
The standout feature of this assembly is the integration of Lincoln's 4C® Lens Technology. This advanced optics system broadens the color range visible through the lens, eliminating the artificial green tint found in older helmets. The result is a "Real Color" view that makes it easier to see the weld puddle, read the arc, and inspect the bead without lifting the hood. Combined with a massive 12.5 square inch viewing area, this helmet provides superior visibility that enhances both safety and weld quality. The lens features four arc sensors and a rapid switching speed, ensuring reliable protection across all welding processes, including low-amperage TIG.

Designed for the Industrial Environment
Built for the rigors of heavy fabrication, shipbuilding, and general construction, the VIKING 3350 PAPR assembly is robust yet comfortable. The integrated air duct connects seamlessly to Lincoln's PAPR systems, delivering purified air to the breathing zone. The unique internal baffling allows you to customize airflow distribution, helping to keep you cool in hot environments and preventing the lens from fogging. The external grind button offers quick access to grinding mode without removing gloves or the helmet, streamlining workflow. Invest in your long-term health and immediate productivity with this top-tier helmet assembly from Lincoln Electric.
