K4181-4 - Lincoln VIKING 3350 Series Foose Imposter Auto-Darkening Helmet

Premium Optics and Industrial Durability

The Lincoln Electric VIKING 3350 Foose Imposter Welding Helmet (K4181-4) represents the apex of welding safety technology, engineered for professional fabricators who demand precision and reliability. This helmet is part of the renowned 3350 Series, distinguished by its integration of Lincoln's proprietary 4C Lens Technology. This advanced liquid crystal display (LCD) system broadens the visible color spectrum, allowing the welder to see the arc, puddle, and base material with unprecedented clarity. Unlike traditional auto-darkening filters that impart a lime-green tint, the 4C technology provides a true-color view, reducing eye strain and enabling better control over the weld bead.

Designed for versatility across industrial applications, the helmet features a perfect 1/1/1/1 optical clarity rating, certified to EN379 standards. This rating ensures zero blurriness, distortion, or shade inconsistency, regardless of the viewing angle. The auto-darkening filter (ADF) offers a massive 12.5 square inch viewing area (3.74 x 3.34 inches), providing operators with a wide field of vision that enhances situational awareness and safety. With a variable shade range of DIN 5-13, this helmet is suitable for Stick, TIG, MIG, and Flux-Cored processes, as well as plasma cutting and grinding.

Comfort is paramount for full-shift operations. The VIKING 3350 is equipped with the innovative X6 Headgear, which utilizes a rotatable front headband and strategically positioned rear supports to distribute weight evenly. This ergonomic design eliminates pressure points and optimizes balance, significantly reducing neck fatigue during prolonged use. The external low-profile grind control allows operators to switch seamlessly between welding and grinding modes without removing the helmet or lifting the lens, streamlining workflow and increasing productivity.

Additional technical specifications include a rapid switching speed of 1/25,000 second, four redundant arc sensors for reliable detection even in obstructed positions, and a low TIG amp rating of 2 Amps. The unit is powered by a replaceable CR2450 battery with solar assistance, ensuring long operational life. The K4181-4 model comes complete with a helmet bag, bandana, replacement lenses, and a sticker sheet.
