K4550-1 - Lincoln VIKING 3250D FGS PAPR System with Standard Battery

Advanced Respiratory and Optical Protection

The Lincoln Electric VIKING 3250D FGS PAPR (Powered Air Purifying Respirator) K4550-1 is a comprehensive safety system designed for professional welders who require both superior optical performance and robust respiratory protection. This NIOSH 42 CFR Part 84 approved system utilizes a loose-fitting positive pressure design to effectively purify ambient shop air, delivering a steady stream of filtered, breathable air to the operator. At the heart of the purification system is a multi-component HEPA filter capable of removing 99.97% of particulate matter at 0.3 microns, offering rated protection against hazardous contaminants such as hexavalent chromium, manganese, zinc oxide, and lead fumes.

Industry-Leading Optics

The helmet assembly features Lincoln's exclusive 4C Lens Technology, which broadens the visible color range in both light and dark states. This technology eliminates the green tint common in traditional auto-darkening filters, providing a true-color view of the arc, puddle, and base material. The lens boasts a perfect 1/1/1/1 optical clarity rating, ensuring zero blurriness, distortion, or shade inconsistency at any angle. With a massive 12.5 square inch viewing area, operators maintain excellent situational awareness and control over their work.

Integrated Grind Shield and Comfort

Productivity is maximized through the integrated clear grind shield and Shade 5 side windows. These features allow for a 161-degree field of view, enabling welders to switch between welding, grinding, and inspection tasks without removing the helmet. The intelligent blower unit is equipped with a standard capacity lithium-ion battery that provides up to 9 hours of continuous operation, sufficient for a full shift. The system also features audible and vibratory alerts to notify the user of low battery status or filter obstruction. The entire assembly is supported by a 4-axis adjustable headgear and a padded belt, distributing weight evenly to reduce fatigue during extended use.
