I have a problem with cutting stainless steel.
I started to cut with N2 5.0 and managed to get a fine cut. My focus point was +4.0, the gas pressure was around 11bar.
After that I changed the cutting gas to O2 and continued cutting steel, the cut was horrible. But before cutting with N2 it was ok. I tried everything and when I finaly changed the lens the cut was fine again.
I spoke with a bystronic service and he said that it is because of the reflection from the staliness steel.
On the lens I cant see any scratch or cracks but somthing happend to it.
Could anyone explain this?
Best regards,
Imre.
