K3540-3 - Lincoln Viking 3250D FGS Auto-Darkening Helmet with Integrated Grind Shield

The Single Helmet Solution for Professional Fabrication

The Lincoln Electric Viking 3250D FGS Welding Helmet (K3540-3) represents a significant leap forward in personal protective equipment for welders. Designed to address the common inefficiencies of switching between welding and grinding tasks, the 3250D FGS integrates a high-performance auto-darkening filter with a large, clear grinding shield. This "Single Helmet Solution" allows operators to transition seamlessly between fabrication steps without removing their helmet, significantly improving productivity and safety on the shop floor.

Unmatched Optical Clarity with 4C Technology

At the core of the Viking 3250D FGS is Lincoln's proprietary 4C Lens Technology. This advanced liquid crystal display system optimizes the view in four key categories: Clarity, Color, Carat (Weight), and Cut (Angle uniformity). The helmet achieves a perfect 1/1/1/1 optical clarity rating, ensuring that the view is free from blurriness and distortion. Unlike traditional lenses that impart a green tint, 4C technology delivers a Real Color View, allowing welders to see the true colors of the arc, puddle, and base material. This enhanced visibility reduces eye strain and makes it easier to control the weld puddle for superior results.

Maximize Your Field of View

Visibility is safety. The 3250D FGS boasts the largest viewing area in its class, with a massive 12.5 square inch auto-darkening display. When combined with the Shade 5 side windows, the helmet provides a 161-degree field of vision. This widescreen perspective is crucial for maintaining spatial awareness in busy fabrication environments. The integrated clear grind shield is ANSI Z87.1 compliant and features an anti-fog coating, ensuring that your view remains unobstructed during grinding, material inspection, and general movement.

Engineered for Comfort and Control

Long shifts require equipment that minimizes fatigue. The Viking 3250D FGS features 4-axis headgear that provides multi-directional adjustments to distribute weight evenly across the head, reducing pressure points. Digital controls allow for quick and precise adjustments to shade, delay, and sensitivity settings, while a low-profile external grind control button lets you switch modes without lifting the helmet. Whether you are TIG welding at low amperages or performing heavy-duty structural welding, the 3250D FGS adapts to your needs.
