1 Safety
1.1 General
Only authorized personnel who have been instructed in and fully understand the necessary
safety procedures must use this laser or get in the vicinity. Access to the laser should be
restricted to authorized personnel. Suitable warnings signs should be placed around the area
where it is operating Any local safety requirements for the operation of this equipment must be
complied with.
1.2 Optical Safety
This is a high-power Class 4 CO2 laser system.
WARNING: This is a class 4 laser product; the laser radiation can cause serious eye
damage - including blindness. Never look directly into either the CO2 laser beam. Injury
to the eyes and skin can result from direct exposure to CO2 laser radiation.
When the laser is operating, all personnel must at all times wear approved laser goggles. It is
vital that these are effective at the wavelength(s) emitted by this laser! The wavelength of the
main infrared beam is 10.6μm.
Never look directly into the main beam or any reflected laser beams - even when wearing
eye protection - or blindness may occur.
Ensure the beam is never reflected outside of vicinity, nor to reflective object, nor doors or
windows to prevent injuries of human body or damage of objects.
Ensure that the beam is never reflected - even partially - back along its path into the laser
head, as this will result in optical damage to its components.
Interaction of the beam with certain materials can cause potentially harmful levels of visible
radiation to be emitted that may cause hazards like fire or smoke. Appropriate protective

measures must be taken in this case.
1.3 Electrical Safety
The power supply of this system is high voltage power supplies (DC 0-38Ma, 10kV-30Kv DC
high voltage power supply) that should be installed and operated under the professional
technicians’ instructions.
WARNING: This equipment contains lethal AC and DC voltages. These may still be present
even when the power is disconnected
No electrical hazard exists if the system is operated normally. But this requires: ①Connection
wire are connected correctly, wires are intact. ②LASER equipment and power supplies are
installed in appropriate location. ③LASER equipment is properly grounded. When the LASER
equipment is operating, personnel in the vicinity should wear insulated clothing and remove
conductive clothing as instructed.
WARNING: High voltages exist in LASER equipment, inside power supplies and
connection wires
1.4 Others
Safety beam stop devices are not equipped on this LASER equipment; operating conditions are
controlled by the control systems of LASER machines.
1.5 Declarations
If you have any doubts while operating the laser, try to contact us first to avoid unexpected
irrevocable damage.
Laser Tube is a complex and fragile glass product, please keep it in a safe place, do not adjust
any parts on the laser, man-made damage to our company will not be returned or warranty!

3 Preparations and Installation
3.1 Products Introduction
R series laser tubes are our own patented technology, using physical methods to effectively optimize
the output spot diameter, to improve the output power. And also, resolve the problem of spot modes
altering. The resonator optics are from US II-VI Infrared, with a good spot pattern. New
international catalytic technology is used to enhance the discharge coating layer and catalytic
reduction performance, resulting in stable output and longer life.
R-series laser parameter table is shown in Table 1.

3.2 Electrical requirements
Input power requirements: 20A/220~240V/50Hz AC
(Contact us for other electrical requirements are optional)
3.3Coolant requirements
The R series lasers require an industrial water chiller with distilled water, or preferably, deionized
water
Water Cooling Machine Requirement:
Water Temperature: 20℃～30℃；
Lift: 10m～15m；
Waterflow: 3L/min～13L/min.

3.4 Environmental Requirements
The R series lasers should be operated or stored in a dust-free condition the working or storage
condition please refer to the Table 2. Below. The lasers PSU should be operated in a well-ventilated
condition. The working area must comply with the local operation safety standards.

Warning: While the temperature of storage environment underneath 0℃, the coolant
(Water)inside the lasers must be drain out completely.
3.5 Packaging
Please check the packaging to ensure there is no damages, when you receive the laser. If any
damages determined at delivery, please contact our sales persons immediately. If the package is
intact, please take the laser out and check if it’s bumped or damaged and have the test only after
ensuring the laser is good and intact. Please contact our sales persons should there be any anomaly.
The packaging should be retained for any future storage or shipment of the laser.
3.6 Installation Procedure
(1) Please install laser tube according to the marking on the laser, connect the wires of positive and
negative terminal, inlet pipe and outlet pipe of the laser correctly.
(2) Turn on the chiller, adjust the laser direction, and ensure that the coolant is full of water jacket
tube and there is no blockage.
(3) Remove the window label and turn on the laser power supply to adjust the optical path.
Return and repair of the laser tube: If the lasers should be returned, please use the original
packaging and contact us in advance for authorized return.
Warning: All coolant should be drained out completely before shipping (an air pump
could be useful for an aid)
Remarking: During the adjustment process, please make sure that the laser does not
impact, knock and do not contaminate the laser lens.
