The Lincoln Viking 3350 series welding helmets are the premium quality helmets from this manufacturer.

The 4C process gives these helmets the highest protection rating of 1/1/1/1 and a clearer view by minimising the traditional green tint.
A clearer view is a factor in reducing eye fatigue and therefore provides additional comfort for the welder, while also offering increased visibility of the weld pool for higher quality welding.

This welding helmet is available in 3 finishes and comes with a 3-year warranty.

It features 4 sensors, a large 133 x 144 mm screen, an internal shade adjustment from 5 to 13, and a grinding mode.
Supplied with a CR2450 battery and a carrying case.

Possible welding processes / MMA - TIG and pulsed TIG - MIG and pulsed MIG - flux-cored wire as well as gouging and grinding operations.

This auto-darkening welding helmet features 2 sensors.
Solar power + 2 AAA batteries
Viewing area: 98 x 40 mm. Wrap-around shape for optimal head protection.
Switching time light/dark: 1/25000 sec
Return to light state adjustable from 0.1 to 1 second.
Adjustable shade from 9 to 13 for welding.
Grinding mode via internal button.

the "LS" technology applied to the lens of this welding helmet, in addition to its role of protecting against harmful rays, helps increase the penetration rate.
In clear mode, the lens lets more color through to the welder's eye, allowing a more precise rendering of detail by reducing the eye's adaptation effort.
The welder will be more precise in their movements and less fatigued during welding operations. 

18-month warranty.

 Lincoln Electric's exclusive 4C technology liquid crystal display (LCD) increases the spectrum of visible colors. Unlike the traditional auto-darkening filter, 4C® technology broadens the range of visible colors and shades whether the light is diffuse or dark. It eliminates imperfections and color saturation, allowing you to clearly see the material being welded, the arc and the weld pool, while reducing eye fatigue.
