Specification :

The Optrel OSC has been on the market for more than 10 years and is still number one with many welders.
The simple, but pleasing shape of the OSC, together with the high quality DIN 9-13 cartridge, offers long-lasting and reliable protection.

Thanks to the large protection level knob on the outside of the helmet, the protection level can be changed easily without removing the helmet even when wearing gloves.
