The PAPR is an all - in - one system that purifies the shop's ambient air and supplies filtered, breathable air for up to 8 hours non - stop. The two - speed blower sends air through the hose to the VIKING® 3350 helmet, which offers 1/1/1/1 optical clarity. A unique adjustable baffling system inside the helmet keeps air away from your eyes, preventing dryness. With an Assigned Protection Factor of 25, it's a top - notch choice. In welding environments where proper ventilation is a challenge, this PAPR brings fume protection and filtered air directly to the operator all day long. It stands out on four key parameters: Comfort, Performance, and Efficiency. It's lightweight and comfortable, with the blower weighing 2.20 lbs and the whole system at 6.19 pounds, mostly in the belt pack and hose, keeping the weight off your head and shoulders. The two air - flow settings let you adjust for maximum comfort and avoid eye dryness. The battery lasts at least 8 hours, outperforming competing systems. Audible and vibrating alarms notify you of low battery or low air flow. The system maintains positive pressure at 180 and 210 liters per minute and automatically adjusts fan speeds to keep the airflow steady. The product comes with a blower unit, VIKING 3350 black helmet, head cover, hose, 2 particulate filters, 29 - 52in. padded belt, shoulder strap, 120V battery charger, duffle bag, rechargeable battery, pre - filter, spark guard, hose cover, extra helmet cover lenses (2 inside and 5 outside), and an instruction manual.
Using the Lincoln Viking PAPR 3350 Welding Helmet is easy. First, put on the belt pack with the battery and blower. Connect the hose to the blower and then to the helmet. Adjust the shoulder strap and belt for a comfortable fit. Turn on the system, and you can choose between the two air - flow settings according to your comfort. When the audible or vibrating alarm goes off, it means the battery is low or the air flow is insufficient. Replace the battery or check the filters. As for maintenance, regularly clean the filters. You can use a soft brush to remove dust and debris. Replace the particulate filters and pre - filter as recommended in the instruction manual. Keep the helmet and other parts dry and store them in the duffle bag when not in use. This will help keep your welding helmet in good condition and ensure its long - term performance.
