The Lincoln Electric Co. launched Viking 2450 and 3350 Series auto-darkening welding helmets that feature 4C optics, innovative headgear to improve comfort and a low-profile external grind button to increase productivity. The X6 Headgear contours to the operator’s head to evenly distribute weight across six key contact points. The addition of the external grind button allows the operator to switch quickly between weld and grind modes without having to remove their helmet or gloves. This significantly reduces operator downtime while offering additional safety benefits. The helmets are available in 24 styles.
