If the focusing optics is started following a fault message,
without having eliminated the cause of the fault, laser light
may be emitted from the focusing optics for a few
milliseconds.
This uncontrolled welding may destroy the workpiece.
Ø
Eliminate the fault on the focusing optics immediately.
Crossjet and MVE nozzle
A crossjet can be used on the cassette receptacle for welding
applications with strong spatter and vapor formation.

Objective with crossjet Fig. 3-25
Below the crossjet receptacle is the connection for the supply
air and the crossjet connected to it.
The crossjet generates an air flow horizontal to the laser beam
focus. The air flow deflects particles and vapors from the protec-
tive glass. Impurities on the protective glass are reduced.
Note
To optimize the effect of the crossjet, the air supply must remain
switched on for about 3 seconds before starting and after finish-
ing welding.
