The Lincoln Electric Lincoln Viking 3350 ADV Series Auto-Darkening Welding Helmet is a professional auto-darkening welding helmet featuring Lincoln Electric's exclusive 4C® lens technology for unmatched clarity, color accuracy, and reduced eye fatigue during extended welding sessions. Engineered for welders performing MIG (GMAW), TIG (GTAW), Stick (SMAW), and plasma cutting operations, this helmet provides superior arc visibility with ADV (Advanced) lens technology in a comfortable, balanced headgear design.
Lincoln Electric's 4C® lens delivers true-color optical clarity in both the darkened and light states, allowing welders to accurately identify weld puddle characteristics, base metal color, and joint geometry that conventional green-tinted lenses obscure. The Viking 3350 series offers a broad auto-darkening shade range of 9–13 with fast switching speed for reliable arc flash protection across all covered welding processes.
