Nozzle replacement
The nozzle of the plasma generator has to be replaced in certain intervals depending on the application.
The nozzle replacement cycles were determined by relyon plasma in standardized tests.
-
Copper nozzles operated with compressed air:
approximately 200 hours
-
Copper nozzles operated with nitrogen:
approximately 1000 hours
Deviations are possible depending on the application.
To replace the nozzle, carry out the following steps:
1. Switch of the device and wait until the plasma generator is cooled down.
2. Unscrew the nozzle (2) together with the coupling nut (1) (right-hand thread).
Caution: by removing the nozzle, the ceramic bushing (4) and the spacer may fall out of the
generator housing (5)!
3. Remove the nozzle (2) from the coupling nut (1).
4. Insert the new nozzle (2) into the coupling nut (1).
5. If necessary, mount first the spacer (plastic) and then the ceramic bush (4) into the generator
housing (5).
Caution: Ensure the correct order for reassembly!
6. Screw the nozzle (2) together with the coupling nut (1) on to the generator housing (5) and tighten
them hand-tight.
7. The nozzle is now replaced.
