1.2 Laser safety level
According to European standard EN 60825-1, clause 9, this series of lasers belong to 4 types of
laser instruments. The product emits laser radiation with a wavelength of 1080nm or around
1080nm, and the optical power radiated from the output head is greater than 100W~3000W
(depending on the model). Direct or indirect exposure to such light intensity can cause damage to
the eyes or skin. Although the radiation is invisible, the laser beam can cause irreparable damage
to the retina or cornea. Suitable and certified laser protective glasses must be worn throughout the
operation of the laser.
WARNING: laser safety protective glasses should be worn throughout the operation of
the product. Laser safety protective glasses have laser wavelength protection selectivity, so
please choose the laser safety protective glasses that accord with the laser output band of
the product. Even if you wear laser safety glasses, it is forbidden to watch the output head
directly when the laser is electrified, whether or not it is in the state of light.
1.3 Optical security
If there is dust on the lens of the laser output head, the crystal of the laser output head will be
damaged or the laser will cause irreparable damage.
CAUTION: do not output the laser without the laser output head protection cap
removed, otherwise the laser output lens or crystal will burn down.
1.4 Electrical security
Ensure the product ground wire is effectively grounded and the environment is safe and reliable.
WARNING: product grounding disconnect will cause the laser shell to be electrified,
which may cause personal injury to the operator.
Ensure the AC voltage supply is normal.
CAUTION: the wrong wiring or supply voltage will cause irreparable damage to the
laser.
1.5 Other safety precautions
Do not look directly at the laser output head while the laser is running.
Do not use fiber laser in dark.
Please strictly follow the laser manual to operate the laser, otherwise any damage to the laser will
not be guaranteed.
The laser does not have built-in usable accessories, all repairs should be carried out by GT Lasers
technicians. To prevent electric shock, please do not damage the label or remove the lid, otherwise
any damage to the laser will not be guaranteed.

3.0 Product Installation
3.1 Actual configuration list
Please refer to the packing list in the packing box.
3.2 Unpacking and inspection
Through specially designed packaging materials and boxes, GT Lasers ensures that the laser can
always be fully protected during transportation. Nevertheless, to prevent the unpredictable
situation in the transportation process, the user still needs to carefully check whether the packing
box is placed correctly and whether there is any damage such as collision, cracking and flooding
outside the box before opening the box. Once the external box is found to be abnormal, please
inform GT Lasers in time so that we can deal with it as soon as possible.
After unpacking, please check whether the packing list is consistent with the actual items. If in
doubt, please contact GT Lasers in time.
When the laser is taken out of the box, attention should be paid to avoid the collision or violent
vibration to the laser. When taking out the coiled laser output cable, we should pay special
attention to it, do not twist, bend, pull the laser output cable, and avoid the collision and vibration
of the laser output head.
CAUTION: laser output cable is a precise optical device, twisting or overbending the
output cable, vibration and impact of the laser output head will cause irreparable damage
to the laser.

1) Ensure reliable grounding before using the laser.
2) The laser output head is connected to the output optical cable. Please check the laser output head
carefully to prevent dust or other pollution. Please use special lens paper when cleaning the laser
output head.
3) If the laser is not used as specified in this manual, the laser may be in an abnormal working state
and cause damage.
4) It is forbidden to install the laser output head when the laser is in operation.
5) Do not directly watch the laser output head, and be sure to wear laser protective glasses while
operating the laser. The best reliability and performance will be acquired when the laser is
installed in an air-conditioned environment.

CAUTION: do not expose this product to a high humidity environment
(humidity >95%). Do not let this product work below the dew point temperature. (As Table
below)
CAUTION: in actual use, the ambient temperature exceeds 30℃. In order to
effectively prevent condensation, clean dry air should be injected into the one-way air inlet
valve at the back of the chassis, and the air pressure should be kept at 0.1Mpa.

3.5 Notes
1) Before connecting the laser to the AC power supply, ensure that it is connected to 220V AC
voltage, wrong connection to the power supply will cause irreparable damage to the laser.
2) It is very important to ensure that the output end of the adjusted laser output head is clean,
otherwise the laser will be irreparably damaged.
3) When the laser is not used, please cover the output head protective cap, do not touch the lens at
the output end. If necessary, use special lens paper and alcohol to clean the lens.
4) The loss of optical power may be caused by incorrect operation by the above specifications, such
loss will not be covered by warranty.
3.6 Installation dimensions
Figure 1 Laser dimensions (unit: mm)
Figure 2 QBH Output head (unit: mm)
Before the laser works, the two copper contacts (Interlock pins) on the output head must be short
connected, otherwise the laser cannot work normally.
3.7 Installation notes
1) Placing the laser horizontally in an appropriate position and fixing it as necessary.
2) Please check whether the AC power supply of the laser is at the appropriate voltage (2 sets 220V
AC±10%, 50/60Hz) and whether the grounding wire is good before the laser is powered on.
3) Connect the power line to the control cable of the laser in the uncharged state.
4) Connect the cooling system to the laser and the output head according to the the water inlet and
outlet mark.
5) Please check the output head of the laser, make sure it is clean and then install it on the equipment.
6) Do not step on, squeeze or overbend the protective tube during the installation of the jumper wire
to avoid damage to the optical fiber.
7) In the process of installing the jumper output head, the surrounding environment should be kept
clean (do not use an electric fan to dissipate heat in summer to avoid heavy dust in the air).
