The Lincoln Electric VIKING 3350 is Lincoln Electric's flagship auto-darkening welding helmet, built for welders, fabricators, and tradespeople who require the highest optical performance and all-day comfort. Featuring 4C® Lens Technology with an expanded viewing area, the VIKING 3350 delivers true-color arc visibility — reducing the green tint of conventional ADF helmets — for precise weld pool control across MIG/GMAW, TIG/GTAW, Stick/SMAW, and FCAW processes. Shade range 5–13, high-speed arc-sensing, ANSI Z87.1/CSA W117.2 compliant. Available in sixteen graphic designs.
