KP3706-1 - Lincoln Viking 3250D FGS Replacement Headgear Assembly

Genuine Lincoln KP3706-1 Replacement Headgear for Viking 3250D FGS

The Lincoln Electric KP3706-1 is the official OEM replacement headgear assembly specifically manufactured for the Viking™ 3250D FGS™ Welding Helmet. This assembly is critical for maintaining the functionality and safety of your FGS hood. The "FGS" designation refers to the Flip Grind Shield design, which inherently changes the center of gravity compared to standard fixed-front helmets. This headgear is engineered to manage that specific weight dynamic, utilizing a specialized vertical position hinge that keeps the helmet securely out of your line of sight when raised, preventing accidental drops that can interrupt workflow.

Technical Features and Adjustability
The KP3706-1 distinguishes itself with a highly adjustable suspension system. It features a ratchet-adjustable back headband that provides secure tensioning with a simple turn. The mechanism is designed to hold its setting rigorously, preventing the "creep" that occurs with inferior generic headgear. The assembly includes a padded front headband and a rear comfort cushion, which work in tandem to eliminate pressure points. The top straps are adjustable to control the ride height of the helmet, ensuring the viewing area aligns perfectly with the welder's line of sight.

Installation and Compatibility
This kit comes fully assembled and ready to install. It includes the main halo, the adjustable top straps, the rear ratchet mechanism, and a pre-installed sweatband. Installation is straightforward: simply unscrew the retention knobs on your 3250D FGS shell, remove the old suspension, and slot the new KP3706-1 into place. It is important to note that this headgear is compatible ONLY with the Viking 3250D FGS series. It will not fit standard 3350, 2450, or 1840 series helmets due to the specific mounting requirements of the FGS shell. Using the correct headgear is essential for the proper operation of the flip-up mechanism and the auto-darkening filter's sensor positioning.

Durability for Industrial Environments
Constructed from high-impact, flexible polymers, the KP3706-1 is built to withstand the rigors of industrial welding environments. It resists cracking from flex fatigue and stands up to the heat and UV exposure typical of heavy fabrication. Whether you are working in structural steel, pipeline, or automotive fabrication, this replacement part ensures your PPE performs as intended, keeping you safe and compliant.
