The new 4C ADF Technology improves the performance of the lens in the 4 most important categories to the welder:

• Clarity - Optical Clarity 1/1/1/1
• Color - Real Color View
• Carat - Light Weight
• Cut - Even Shade From Any Angle

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.

A VISION FOR BETTER WELDS

Better Clarity, Real Color View
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.

Easy On The Eyes
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.

Wide-Screen View
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.

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 enables more performance from the battery. Now you can keep welding, increase your productivity and get more from your helmet lens.
