Description
Lincoln Viking 3250D FGS SAR (Supplied Air Respirator) K5443
Genuine Lincoln Viking 3250D FGS SAR (Supplied Air Respirator) is a continuous flow respirator and auto-darkening welding hood that connects directly to your centralized air system or compressed air cylinder. The K5443 SAR supplies breathable air at a flow range between 180 to 290 LPM (Liters Per Minute). The adjustable air regulator can also cool incoming air by as much as 50F (28C), keeping the operator cool and comfortable all day long. The Viking 3250D FGS SAR has an OSHA Assigned Protection Factor of 25, for loose-fitting respirators. It is available with or without a 25 ft. input air hose.
The SAR’s Viking 3250D FGS welding helmet, with integrated grinding shield, combines 4C optics with a wide angle grinding lens. The extra large 12.5 square inch auto-darkening lens features Lincoln’s exclusive 4C lens technology. Proprietary 4C liquid crystal display passes more true color through the lens in both light and dark states to create the clearest view of your work piece. The Viking 3250D welding hood has a perfect 1/1/1/1 optical clarity rating, meaning lens distortion and blurriness are completely eliminated, shade is consistent through every square inch of the lens and the welding arc looks crisp and clear at any angle.
The FGS’s grinding shield provides a full 161 degrees of viewing angle while the welding lens is flipped up and out of the way. The extra large clear lens has an anti-fog coating and is ANSI Z87.1 compliant for impact hazards. The Lincoln Viking 3250D FGS auto darkening welding hood comes complete with shade 5 side windows to protect from peripheral arc flash and has a five year lens warranty.

Is designed to supply an air flow range of 180-290 LPM (liters/minute) with the ability to cool the incoming air by up to 50F (28C).
From the regulator propels hot air away from the user, in order to ensure cool and comfortable all day use.
Of 25 for loose-fitting respirators.
Optimizes contrast and clarity in welding and light states – reducing eye strain and operator fatigue.
The 12.5 square inch auto darkening lens provides a large field of view to increase versatility and operator control.
This rating is determined by measuring blurriness, distortion, shade consistency and angle uniformity of the auto-darkening welding lens.
For superior lens response.
Excellent performance on low amperage DC TIG welding applications.
Low profile external grind control allows you to quickly switch between weld or grind modes.
Helps welding lens distinguish between arc light and sunlight for a consistent welding experience indoors or outdoors.
Increase peripheral vision in the closed helmet position.
Provides protection from spatter and improves comfort.
Protects operators from impacts while providing a clear viewing area for grinding and material inspection.
