1.2 Laser Classification
The FCA series Hand Laser Welding System adopts a single-mode fiber laser, which can
emit laser radiation with a wavelength in the range of 1080 ± 3nm, which is invisible light. The
average power of the products is ranged from 10% to 100% at a maximum power about 1000W,
1500W or 2000W, which classifies the series of lasers Class 4 laser instrument. Direct or indirect
exposure of this level of light intensity may cause very serious damage to the eyes or skin. In view
of this, appropriate and approved laser safety protective glasses must be worn all the time while the
laser is operating. At the same time, no directly or reflectively emit on your skin.

1.4 Safety Instructions for Optical Operation
We strongly recommend that you read the following procedures before operating the fiber
laser:
(1) Never look directly into the optical output when the Electrical switch is on.
(2) Make sure that a pair of appropriate and approved laser safety protective glasses is worn all
the time while the laser is operating.
(3) No eyes are on the path of the laser beam (direct or reflected light, scatter light from high
reflective material, etc.), at the same time, the direction of 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) If you are ready to emit light, be sure to confirm whether the red light position is correct.
The laser cannot be obtained under the following conditions:

Beijing Reci Laser Technology Co., Ltd
User Guide for FCA Series Hand Laser Welding System
6
A: No red light.
B: When no swing is set, the red light is not in the center.
C: After setting the swing, the red light is blocked.
(5) Please ensure that the protective lens of the welding gun is clean and free of dust,
otherwise the laser will be irreparably damaged. Before use, carefully observe whether the protective
window mirror of the welding gun is clean. If there is any pollution, the window mirror needs to be
replaced. The damage caused by non-standard operation will not be guaranteed.
(6) If the welding gun is heated during use, please stop using it immediately and check the
problem.
CAUTION :
The dust on the window mirror of the welding gun will cause the lens to
burn when the light comes out, and the continued use after burning will even
cause the internal damage of the laser.
1.5 Safety Instructions for Electrical Operation
We strongly recommend that you read the following procedures before operating the fiber laser:
(1) Make sure the power source connected to the equipment is properly grounded with PE wire.
At the same time the shell of this equipment must be properly grounded. Any interruption of the
ground loop may result in personal injury.
WARNING :
The input voltage of the fiber laser is AC current (220VAC), which may
cause risk of electric shock. All the relevant cables and connection wires have
potential hazards.
(2) Make sure that the input AC voltage and capacity meet the requirements of the very series
of lasers.
(3) If the air switch shut down frequently, please contact Reci as soon as possible to ensure the
safety use of the equipment.
CAUTION :
(1) Any incorrect wiring method or AC voltage may cause damage to people
or instrument.
(2) There are no devices in the product that need to be used by the operator.
Do not try to open the product cover, otherwise electric shock may be
caused, and the laser warranty will be invalid accordingly.

(2) Please cut off the power supply when unattended.
(3) It is strictly prohibited to shield the protection. The workpiece clamp and welding gun
nozzle must be closed before outputting the laser, otherwise there will be potential safety hazards.
(4) Never aim the laser at the body.
(5) Do not operate by non professionals. Keep out of the reach of children.
(6) Please operate the laser in strict accordance with the product manual, otherwise any
damage to the laser will not be guaranteed.

Chapter 3 Installation of the laser
3.1 Dimension of the machine
The dimension of the laser device is just below：（Take FCA1500 as an example）
Figure 3.1 Overall dimension（unit: mm）
3.2 The optical output head
A passive device named QBH was used as the optical output in the FCA series laser, its
dimensions are just as figures below.
Figure 3.2 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).

3.4 Connection and Requirements
3.4.1 Connection of external circuit and air circuit
Refer to the relevant power requirements in table 2.2. Before connecting the power supply,
ensure that the input voltage conforms to the standards indicated in the technical specifications. The
equipment must be connected with auxiliary gas with sufficient air volume before operation, so as
to dissipate the heat load generated during operation and protect the damage to the welded joint
caused by spatter during operation.
Note: the air pressure of the input gas shall not be greater than 0.7MPa.

3.4.2 Requirement of the cooling system
The laser adopts air-cooled heat dissipation. When selecting the placement position, please
operate in a non closed and narrow space with good air circulation conditions. Do not place any
objects that may block the exhaust on the top of the machine. The air flow direction is shown in the
following figure:
Fig. 3.3.2a schematic diagram of air inlet and exhaust
The requirements for laser placement space are shown in the figure below：
Figure 3.3.2b laser placement space requirements
Note: the filter screens of the two air inlets must be cleaned regularly. The equipment damage
caused by improper use / maintenance will not be guaranteed.
3.5 Installation precautions
(1) The laser need to be placed horizontally and fixed, without inversion, side setting,
vibration and impact.
(2) When connecting the power line and control line, make sure that the power supply is
disconnected for non live operation.

Beijing Reci Laser Technology Co., Ltd
User Guide for FCA Series Hand Laser Welding System
15
(3) When the laser is connected to the gas circuit, it is necessary to recognize the gas inlet
and outlet signs and connect them according to the signs. See Fig. 4.2 for the air inlet.
(4) During the installation of QBH, the surrounding environment must be cleaned, in order
to protect the QBH from polluted.
(5) Check the output head and clean it if necessary. If any dust on the QBH end face
cannot be cleaned, please contact Reci, and at the same time the cleaning procedure must be
performed by personnel of Reci or authorized by Reci.
(6) Prevent the delivery cable from treading, excessive bending, smashing with heavy
objects during installation. There would be no warranty if the cable is damaged due to
external force.
CAUTION:
(1)Please make sure the laser optical output and the processing head are all
dust-free before connecting them together.
(2)Please take good care of the black protective cap of QBH from being
polluted; otherwise, it will cause indirect pollution to QBH output head when
the protective cap is put on.
(7) After the installation or connection of the cooling system, optical system, electrical
wires, remember to do a recheck: make sure the connection of the electrical system is correct
(see section 4.3-4.5 for details), the capacity of the electrical supply power is the one
(AC220V , 50Hz/60Hz), and the ground connection is available.
CAUTION:
Never do the recheck with any electrical switch on, especially the air
switch for the AC 220V on the wall.
(8) Handle gently with the QBH while installing or removing it.
(9) Keep the deliver cable a minimum bending diameter of 400mm for storage, or 600mm
for laser on.
CAUTION:
please make sure the laser optical output and the processing head
cable should be kept as natural as possible and not be distorted
(2) Too small bending diameter for the deliver cable will damage the
device.
