The entry-level expert helmet.

Thanks to the extremely high quality filter and use of the expert helmet shell,

the welder benefits the standard DIN 10 and DIN 11 function plus comfort and protection benefits.

The welder can adjust the shade level to suit his requirements using the slide switch on the rear of the filter.

It can be set to either DIN 10 or DIN 11. The detection angle for ambient light can also be adjusted using the sensor bar.
