Lincoln Electric VIKING™ 3350 PAPR Welding Helmet System

The Lincoln Electric VIKING™ 3350 PAPR Welding Helmet System (K3930-1) delivers advanced respiratory protection and premium optics for professional welders working in environments with heavy fumes and particulates. This complete Powered Air-Purifying Respirator (PAPR) system filters contaminated air and supplies clean, breathable airflow directly to the welder while maintaining the legendary visibility of the VIKING 3350 welding helmet.

Designed for demanding fabrication, maintenance, and structural welding applications, the system combines Lincoln Electric’s industry-leading 4C® Lens Technology with an intelligent blower and HEPA filtration system. The result is superior optical clarity, enhanced weld visibility, and consistent airflow protection throughout the workday.

The integrated PAPR unit continuously pulls ambient air through a multi-stage filtration system capable of capturing 99.97% of particulates down to 0.3 microns. Clean air is delivered to the helmet through a flame-resistant hose, helping reduce exposure to welding fumes while keeping the operator comfortable and productive.

The VIKING 3350 helmet features a large 12.5-square-inch viewing area with a perfect 1/1/1/1 optical clarity rating, giving welders an accurate view of the arc, puddle, and base material. With a rechargeable lithium-ion battery providing up to 8–9 hours of runtime, the system is built to handle full shifts in fabrication shops, construction sites, and industrial environments.

This complete kit includes the welding helmet, blower unit, HEPA filters, battery, charger, hose assembly, and accessories needed to begin using the PAPR system immediately.
