The traditional inside display is super simple to use and make adjustments for the view of your choice. Available in a variety of graphics, this matte black is a customer favorite.  The 4C ADF Technology improves the performance of the lens in the 4 most important categories to the welder: Optical Clarity 1/1/1/1 Real Color View Light Weight Consistent & Even Shade From Any Angle  Perfect 1/1/1/1 Optical Clarity 4C technology lens with Perfect 1/1/1/1 optical clarity rating. The rating is determined by measuring blurriness, distortion, shade consistency and angle uniformity. Resulting in the best view of your welds with less green tint and more clarity of detail.  Excellent performance for low amperage TIG welding.  4C Lens Technology Unlike traditional auto-darkening filters, 4C lens technology broadens the color range & hues which can be seen in both light and dark states. This eliminates imperfections and color saturation to create the clearest view of the base material, arc & puddle while reducing eye strain. External Low Profile Grind Button Easily switch between weld and grind mode by pressing the low profile silicone button for 3 seconds. Ability to switch into grind mode without removing gloves and taking off the helmet.  Outdoor Performance Exclusive technology can identify the differences of a welding arc and sunlight without switching modes. Perfect for welding outdoors or with a garage door open.  X6 Headgear Innovative and easy-to-use X6 headgear distributes weight, reduces pressure, and optimizes balance. Flexible cushioned back pad and rotatable padded headband allow for all-day comfort. Hard hat adaptable and cheater lenses are available.  Extra Large Viewing Area The 12.5 square inch auto darkening lens provides the best view of your welds. The helmet weighs only 1.4 pounds and has four arc sensors. Increased Battery Life The longer you can see clearly, the more you can weld. And more welds mean higher productivity. Improvements to the ADF’s circuitry enable more performance from the battery. Now you can keep welding, increase productivity and get more from your helmet lens.   *5-Year Warranty on the Viking 3350 4C Matte Black K3034-4 Included with Product  Lincoln Helmet storage bag Bandana 5 outside cover lenses 2 inside cover lenses Stickers Specifications Click the image below to view the full spec sheet.
