Raycus continuous wave fiber laser uses different laser output cables
according to different laser models.
3.2.1 RFL-C1000 ~ RFL-C1500 Output Optical Cable
The output cables of Raycus RFL-C1000 ~ RFL-C1500 handheld welding
fiber lasers are self-made IQB output cables. The specific appearance dimensions
are shown in Figure 4 below:

For QBH output optical cables, the two copper contacts
(InterLock pins) on the output head must be shorted before the
laser works, otherwise the laser will not work properly. Usually
the copper contacts are automatically shorted after the output
fiber cable is installed in the processing equipment.
Before installing the output cable in the processing head, the
lens of the output cable must be inspected. If the lens is dirty, it
must be cleaned.
It is forbidden to disassemble the output lens by anyone other
than Raycus, otherwise the warranty will be invalidated.

1) Temperature setting of cooling water:
25±1℃
2) Requirements on Cooling Water:
Purified water should be used.
In order to prevent the growth of mold that may lead to blockage,
adding alcohol solution to about 10% of the total volume is
recommended.
If ambient temperature is between -10℃and 0℃, we recommend to
use 30% alcohol(volume ratio), and replace it every 2 months.

If ambient temperature is below -10℃, the chiller with both heating
and cooling functions must be used, and keep it in full-time operation.
3) Other cooling system requirements:
Check the entire water system and joints for leaks, the first time
starting the cooling system. The external water pipe must be installed
and connected according to the water inlet (IN) and water outlet (OUT)
indicated by the laser, otherwise the laser may not work properly.
If the laser is not used for a long time, the cooling system and the
cooling water inside the laser should be drained, otherwise it will
cause irrecoverable damage to the laser.
Set the water temperature of the cooling system correctly
according to the ambient temperature. If the water
temperature is set too high, the laser will not work properly.
If the water temperature is set too low, condensation will
occur inside the laser or the laser output cable, which will
cause irrecoverable damage to the laser.
Before staring the laser, the cooling system must work
properly and the water temperature reaches a suitable
temperature.
3.4 Installation rule
1) Place the product in an appropriate position, immobilize it if necessary.
2) Check if the power supply has the correct voltage (380VAC ±10% ，
50/60Hz), and the earth line is connected, make sure it is firm and
reliable
3) Connect the power cable and control cable to the product when power
supply is OFF.
4) Connect the cooling system to the laser and output fiber cables according
to the water inlet and outlet signs.

5) Please check the laser output head and do the necessary cleaning before
installing it in the device. If you find that there is dust or foreign objects
that cannot be cleaned, please contact Raycus in time, and do not
continue installation and operation for the time being.
6) Prevent the delivery cable from treading, pinching or excessive bending
during installation.
7) please handle the laser output cable carefully, and do not receive
vibration during the installation and disassembly.
8) Make sure the environment is clean, or the output head may be
contaminated. It is prohibited to use fan during installation, which will
cause dust in the air.
9) The minimum bending diameter of the transmission cable of the laser
shall not be less than 20cm in the non-working state (such as transport
and storage). The minimum bending diameter should not be less than
30cm when the laser is work.
CAUTION: All the cables can only be connected when
power supply is off. Hot plug may damage the device.
Ensure that there are no fiber bends in radius less than 30cm
when the product is installed. Avoid excessive twisting and
tight bends during the robotic arm movements.
Tight bends will damage the laser delivery system.
Before the laser output cable is assembled, the lens and the
cutting head cavity must be clean and free of pollution.
Keep the protective cap properly, prevent it from
contamination; Or the aperture will be contaminated when
capped.
