Water in the resonator

[Quiron]

Hello all , I´m new on the forum so please excuse me if I go past any protocol.

We have a Trumpf Tc6000l with a 2kw LASER . Over the past 11 years we had 3 water leaks in our resonator , the last leading a complete resonator change .All maintenance is done in accordance to the manual and the demineralized water is certified .
Is this normal ? If not , any ideas on what is going wrong please .

Thank you in advance.

Did you get feedback from the laser techs?
What did the service reports say?
I'd hope your service vendor could review your history and offer some advice.

This was there report :

"The development of corrosion is depending on different factors and can occur after 1000h or 10.000h e.g.

- The admixture in the cooling water to avoid corrosion was not sufficient

- Missing maintenance on the resonator

- …."

The admixture was added in quantities and timing as specified in the maintenance manual.

After cutting one of the faulty cooling coils, no corrosion was found ,only a very small pierced like hole.
