Lincoln® Viking™ 1840 Digital Aztec™ Auto-Darkening Welding Helmet K4175-4

The Lincoln® Viking™ 1840 Aztec™ auto darkening welding helmet now features fully digital controls with true color optics and a 7.0 square inch viewing area. The 1840 digital 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 digital 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.

Product enhancements also include an expanded range variable shade 7-13 dark state and DC TIG weld rating down to 2 amps. The Lincoln Viking 1840 digital auto darkening welding hood comes complete with Lincoln's pivot-style headgear, for even weight distribution, and has a five year lens warranty.
