Ignite Your Welding Vision with the Lincoln Weldline Viking 3350 Auto-Darkening Helmet: Where Clarity Meets Innovation

The Lincoln Weldline Viking 3350 Auto-Darkening Welding Helmet isn’t just another piece of gear; it’s an extension of your welding expertise, engineered to elevate your performance and protect your vision with cutting-edge technology and unparalleled comfort.


  • Experience Crystal-Clear Vision with 4C™ Lens Technology:  Sharp, high-definition, true-colour viewing experience, even in the darkest shade ensuring precise weld placement and minimising eye fatigue.
  • Unmatched Optical Clarity: Industry’s leading 1/1/1/1 optical clarity rating for zero blurriness, distortion, and shade inconsistency.
  • Effortless Shade Control: Seamless transitions from 5 to 13 allows you to adapt to different welding techniques and amperages on the fly, without interrupting your workflow.
  • Superior Arc Detection: 4 strategically placed arc sensors guarantee instantaneous darkening upon arc strike, safeguarding your eyes from harmful UV/IR radiation. This lightning-fast response ensures unwavering protection, even when working with low-amperage applications like TIG welding.
  • Grind with Confidence: Dedicated grind mode instantly switches your lens to shade 3, allowing you to prepare and clean welds without helmet removal. This streamlines your workflow and eliminates the risk of accidental exposure to harmful sparks or debris.
  • Built for All-Day Comfort: Lightweight, well-balanced design minimises neck strain, while adjustable headgear and sweat-absorbing liner provide a personalised, comfortable fit. Weld longer and harder without sacrificing comfort or focus.
