Lincoln Electric’s VIKING™ 3250D FGS auto-darkening welding helmet (K3540-3) is built for welders who want a clear, controlled view of the work while maintaining comfort through long shifts. It uses 4C® Lens Technology and a 1/1/1/1 optical clarity rating to reduce distortion and help maintain shade consistency, paired with a 12.5 sq. in. auto-darkening display for a wider process view. For added awareness and protection, it includes Shade 5 side windows to increase peripheral vision, a large integrated grinding shield for grinding and inspection, and an anti-fog coating to help keep the lens clear. Comfort and fit are supported by 4-axis headgear with multi-directional adjustment, plus a flame-retardant head covering for spatter protection. Includes helmet bag, bandana, side window covers, and an extra cover lens.
