Hey. I hope this is the right section.
I bought a second "red and black" 130w co2 laser. First one is running fine, all good.
The second one - At some times I hear electric cracking noise, discharge somewhere near tube.
The first machine does perfectly engrave at 150mm/s and 9% power (mat finish, perfect).
The second machine even on 500mm/s and 9% power does engrave at least 0.5mm deep.
Both machines are supposed to be identical..
Any suggestions appreciated. Thank you in advance.

Co2 laser problem, electrical discharge sound, too much power.

Update: So, cracking noise gone by itself and there is a little switch on tube PSU which enables power control.
