The Lincoln Viking 3350 XG Powered Air Purifying Respirator K3930-6 is a top - choice for fabrication environments. Its smart blower system, low - profile grind button, and extra - large welding view with 4C technology set it apart. The 4C lens technology uses Lincoln Electric's proprietary liquid crystal display, offering a clearer and crisper view with less green compared to traditional welding lenses. With a 12.5 - square - inch viewing area, the auto - darkening lens provides an expansive view. The Viking 3350 XG PAPR has a patented directional airflow, allowing users to adjust the air flow's direction and distribution. Switching between weld and grind modes is easy with the industrial button on the left side of the helmet. A subtle green flash from the internal LED notifies you when grind mode is activated. It comes with a multi - component filter system including a spark screen, pre - filter, and HEPA filter that extracts 99.97% of particulates. The package includes a VIKING 3350 XG PAPR Welding Helmet (new version with external grind button), hose with cover, headcovering, 2 HEPA filters, padded belt (29 - 52 in), shoulder straps, 120V battery charger, duffle bag, lithium - ion battery, pre - filter, spark guard, and extra helmet cover lenses (2 inside and 5 outside).
Using this Lincoln Viking PAPR 3350 XG is easy. First, put on the headcovering and adjust the shoulder straps and padded belt for a comfortable fit. Connect the hose to the helmet and the blower unit. When you start working, the auto - darkening lens will adjust automatically. To switch to grind mode, press and hold the industrial button on the left side of the helmet for 3 seconds. You'll see a green flash to confirm it's on. Make sure to regularly check and replace the pre - filter and HEPA filter. The HEPA filter should be replaced when it reaches its capacity to keep the air clean. When not in use, store the respirator in the duffle bag provided in a cool and dry place. Charge the lithium - ion battery using the 120V battery charger when the power is low. Also, keep the extra helmet cover lenses handy and replace them when they get dirty or scratched to maintain a clear view.
