Fiber connectors are generally equipped with a protective glass or a
protective conduit to protect the sensitive quartz block at the fiber end
from contamination or damage during installation. Depending on the
area of application and the required laser power, it may be necessary to
unscrew the protective glass or protective conduit.
NOTICE
Damage to the fiber through improper use of the
quartz block protection
For applications with high vibrations or high acceler-
ations of the process optics, the protective conduit
can become loose around the fiber outlet and fall
into the process optics. Due to the high temperatures
at high laser power, the protective glass or protec-
tive conduit may melt causing damage to the fiber
connector and the process optics.
ð Use the protective conduit or glass only for ap-
plications and under conditions which are ex-
pressly intended to prevent damage to the fiber
connector and process optics.
The section Clean fiber connectors [} 113] includes instructions for
cleaning the fiber connector, correct use of quartz block protection as
well as the correct installation of the fiber connector in the welding op-
tics. Follow the instructions in this chapter to safely connect the fiber
with the welding optics.
5.5.4 Connecting the water supply
NOTICE
Danger of damage to the product
Risk of damage to the laser, fiber connectors and op-
tics due to incorrect connection of the cooling.
ð Note the information in this section before
start-up and maintenance work.
