How do I find eye protection for my laser cutter?

[kolleamm]

I recently received a laser cutter however, I cannot find anywhere not even in the manual what frequency it emits. It's a CO2 machine with a 180 watt laser. It's supposed to be able to cut metal.

Can someone advise me on eye protection, I don't want to risk my vision.

Thanks in advance.

Do not use the machine if you don't know exactly what you are doing.

There is no eye protection that would reduce that laser beam to safe power levels. Do not open the machine, and let an expert (!) make sure that the machine is working properly so the laser beam is fully contained in the machine.

CO2 lasers are infrared, so you don't even see the beam without special equipment.

We won't help you with dangerous activities here.
