Lincoln® Viking™ 1840 All American® Welding Helmet K3173-3

The Lincoln® Viking™ 1840 All American® auto darkening welding helmet features true color optics with a 7.0 square inch viewing area. The 1840 comes with 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 1840 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 Lincoln Viking 1840 auto darkening welding hood comes complete with Lincoln's pivot-style headgear for even weight distribution and has a three year lens warranty.

Viking™ 1840 Features
  • 4C™ lens technology optimizes contrast and clarity in welding and light states - reducing eye strain and operator fatigue



  • Wide Viewing Area - The 7.0 square inch auto darkening lens provides a up to a 16% larger field of view when compared to other helmets in its class
  • Perfect 1/1/1/1 Optical Clarity - This rating is determined by measuring blurriness, distortion, shade consistency and angle uniformity of the auto-darkening welding lens



  • Two arc sensors
  • Pivot-style headgear evenly distributes the helmets weight
  • DC TIG rated to 3 amps - Very good performance on low amperage DC TIG welding applications.
  • External shade control - Conveniently switch between welding shades 9-13 and grinding shade 3.5 without removing helmet
  • Internal sensitivity and delay controls

  • Helmet bag
  • 5 outside cover lenses
