Lincoln Electric VIKING™ 1840 Series Auto-Darkening Welding Helmet, Aztec Design #K4175-4
Lincoln Electric VIKING™ 1840 Series Auto-Darkening Welding Helmet, Aztec Design #K4175-4

The Lincoln Electric Viking 1840 Series Aztec welding helmet offers a seamless blend of form and function. Its ergonomic design ensures optimum comfort, reducing strain during long welding sessions. Experience precision like never before with the state-of-the-art auto-darkening lens and expansive viewing area, providing a vivid and unobstructed sight of your work. Whether you're welding, cutting, or grinding, this versatile helmet is engineered to meet the demands of professional welders.
The VIKING™ 1840 Series, Lincoln Electric's mid-range auto-darkening helmet tier, offers superior 4C(R) optics with a versatile user interface and premium external controls to increase productivity.
The new 4C ADF Technology improves the performance of the lens in the 4 most important categories to the welder:
The 4C Lens Technology upgrade to Lincoln Electric’s VIKING™ welding helmets improves visibility and reduces eye strain by minimizing the traditional lime green coloring in the helmet view screen. 4C technology is ideal for a range of industries such as general fabrication, power generation, shipbuilding, structural, offshore and pipeline that use multiple welding processes, including Stick, MIG and TIG. Whatever the task at hand, 4C technology gives you a clear view to productivity and quality.
Now you can make a good view even better. Upgrading with 4C technology preserves the existing 1-1-1-1 optical clarity rating, but improves visibility by reducing the lime green tint.
Improved visibility and less eye strain means greater comfort for the welder. This combined with an improved view of the weld puddle adds up to better welds.
4C technology enables you to not only see better, but also see more. The large viewing area gives you a full range of vision in relation to the welding area, which enhances operator control.
The longer you can see clearly, the more you can weld. And more welds mean higher productivity. Improvements to the ADF’s circuitry enables more performance from the battery. Now you can keep welding, increase your productivity and get more from your helmet lens.
