K3930-1 - Lincoln Viking 3350 PAPR Welding Helmet System with Standard Battery

Advanced Respiratory Protection for Industrial Welding

The Lincoln Electric Viking 3350 PAPR (Powered Air Purifying Respirator) System, SKU K3930-1, is a comprehensive safety solution designed to protect welders from hazardous airborne particulates. Compliant with NIOSH 42 CFR Part 84 standards, this positive pressure respirator system utilizes a high-efficiency HEPA filter to capture 99.97% of particulates down to 0.3 microns. This level of filtration is critical for environments containing hexavalent chromium, manganese, zinc oxide, and other metal fumes commonly generated during heavy fabrication and industrial welding processes.

The core of the system is the intelligent blower unit, which maintains a consistent airflow at two selectable speeds: 180 liters per minute (Low) and 210 liters per minute (High). The blower features an audible and vibrating alarm system that alerts the operator to low battery status or restricted airflow, ensuring continuous safety compliance. Power is supplied by a standard capacity lithium-ion battery, delivering a minimum of 8 hours of operation, sufficient for a full work shift. The entire system is designed for ergonomics; the blower weighs only 2.20 lbs, and the weight is distributed comfortably via a padded belt, reducing strain on the operator's back and shoulders.

Visually, the K3930-1 integrates Lincoln's premium Viking 3350 helmet shell with 4C Lens Technology. This auto-darkening filter (ADF) achieves a perfect 1/1/1/1 optical clarity rating according to EN379 standards, minimizing blurriness, distortion, and shade inconsistency. The 12.5 square inch viewing area provides an expansive field of view, enhancing situational awareness and weld puddle control. The system has an Assigned Protection Factor (APF) of 25, making it a robust choice for enclosed spaces or areas with poor ventilation.
