laser output must be Shelter by reliable objects.
WARNING :
Even though the protective glasses are worn, staring into the
optical output is forbidden absolutely while the electrical switch of the
laser is on.
(4) Make sure that the black cap of the QBH is taken off when you are
prepared to use the laser.
(5) Make sure the end surface of the quartz head and the protective window
lens of the optical output is clean, if not, please clean it with dust-free lens
paper soaked by high purity (≥99.8%) anhydrous ethanol under a
microscope.
(6) Make sure that the processing devices can support a maximum laser power
above 3000W. If you find that the processing equipment is being heated to
a higher temperature, please stop processing immediately. An appropriate
and approved processing system is needed.

called specular reflections. Although these secondary beams may be less
powerful than the total power emitted from the primary beam, the intensity
may be great enough to cause damage to the eyes and skin as well as
surface of materials.
WARNING :
You must exercise caution to avoid/minimize specular reflections
as these laser radiations are invisible!
(2) Optical accessories relevant to the laser, such as light-sensitive elements
that may be damaged from exposure to the laser light, video cameras,
photomultipliers and photodiodes, need related protections.
CAUTION :
The Reci Single Module Fiber laser is strong enough to cut or
weld metal, burn skin, clothing and paint. In addition, this laser can
ignite volatile substances such as alcohol, gasoline, ether and other
solvents. During the operating process, the flammable materials
around the laser must be isolated.
(3) Please do not operate laser in darkened environments.
(4) Do not turn on the laser without an optical coupling fiber or the optical
output connector.

Chapter 3 Installation of the laser
The appearance of all the products is consistent. So no mark will be made in the
following is specifically. We will use ”1000W” to represent a fiber laser whose
average power can reach 1000W, and so as the other models.
3.1 Dimension of the machine
The dimension of the laser device is just below; figure 3.1 is for front panel and
rear panel of the series fiber laser.
Figure 3.1 Front view and Rear view（unit: mm）
The figure 3.2 describes the side view and bottom view dimensions of 1000W,
1500W&2000W fiber laser; they are the same at appearance size; and then the
figure3.3 is for 3000W fiber laser.

3.2 The optical output head
A passive device named QBH was used as the optical output in the single
module series laser, its dimensions are just as figures below.
Figure 3.4 the top view of the QBH (unit: mm)
The slot size of QBH is standard, matched well with most of processing heads
from the market. During installation, you need to ensure the QBH installed in place,
and then establish a reliable connection between the ring contactor with the
processing head’s contactor; otherwise the laser will give an alarm.
Before the QBH is installed, the end face of the QBH must be checked. Of
course, it must be cleaned when the end face is polluted (check under a microscope).

3.3 Connection and Requirements of the Cooling system
3.3.1 Connection of the cooling system
A water cooler with dual temperature output is required.
For 1000W or 1500W, Polyurethane pipe with outer diameter of 12mm which is
used for quick insertion is needed. For 2000W or 3000W, pipe with inner diameter of
20mm is needed for connecting the laser and the water cooler.
Two segments of quick plug water pipes with outer diameter of 6mm are for
connection between QBH and the water cooler. The method is shown in Figure 3.5:
the outlet of the water cooler is connected with the “WATER IN” of the laser, and the
inlet of the water cooler is connected with the “WATER OUT” of the laser, and so is
the QBH, the new QBH without marked ‘inlet and outlet’ can use any connection
as inlet, another connection as outlet.
Figure 3.5 Sketch Map for the connection of the cooling system
If a water cooler with dual temperature output isn’t ready there, an extra water
cooler for QBH specialized will be needed. And you’d better follow the notes below:
(1) Water with poor quality cannot be used, and the water temperature should not
make QBH dewy.
