OSC.
Evidence of decades of experience.

The optrel osc. The most copied and really often produced welding helmet of its time. 25 years of product life make it a fundamental element in our industry. And still he has a faithful fan base.

Like the optrel p550 in 2016 – today known as optrel neo and more important for the market than ever – the optrel osc gets a facelift. Just the ADF. Full stop.

You will benefit from the following additions from the 5th of June 2017:
