Lincoln Electric has introduced the Viking 3350 XG PAPR (powered air-purifying respirator) helmet, with exterior grind control. The helmet provides ideal respiratory performance, versatility and optic quality, according to company officials. It features a low-profile external button to switch between weld and grind mode, a smart blower system, and an extra-large 12.5-sq.-in. auto-darkening lens using Lincoln Electric's 4C lens technology. The lens offers 1/1/1/1 optical clarity, extreme color accuracy, light weight and an even shade from any angle, which increases operator comfort during long hours of welding.
