The Lincoln Electric VIKING™ 1840 Series Auto-Darkening Welding Helmet represents a step up in optical performance and feature set within the Viking helmet family. Equipped with Lincoln Electric's advanced 4C® Lens Technology, the Viking 1840 delivers exceptional clarity, true-color recognition, and reduced haze compared to conventional auto-darkening lenses — enabling welders to read the weld puddle with greater precision during MIG/GMAW, Stick/SMAW, TIG/GTAW, and FCAW operations.
The 1840 series is designed for experienced welders and professionals who spend extended hours at the arc and demand superior optical performance to maintain weld quality and reduce eye fatigue. Available in distinctive graphic designs including All-American, Aztec, Tempered, and classic Black, the Viking 1840 pairs premium protection with professional styling. With an auto-darkening filter covering shade range 5–13, the 1840 handles the full spectrum of arc welding and cutting applications.
