1. Safety Information
Thank you for choosing Reci CO2 laser tube. This user manual provides you with important information
on safety, operation and maintenance. Please read it carefully before using the product. To ensure safe
operation, please observe the following cautions, warnings and other information in this manual.
1.1 Safety Symbols
Table 1
1.2 Laser Safety Level
Table 2
This product belongs to safety level 4. It emits laser radiation with a wavelength around 10600nm and the
laser power radiated by the output head is bigger than the rated power (depending on the model). The eyes
or skin will be damaged if direct or indirect exposure to such light intensity. Although the radiant light is
not visible, the beam still causes irreparable damage to the retina or cornea. Thus, appropriate and certified
laser safety glasses must be worn throughout the operation.
1.3 Safety Symbols
Figure 1 Location of safety symbols
Cautions:
Refer to a potential hazard on products. It requires a procedure, if not
correctly followed, may result in damage to the product or components.
In order to ensure normal use of requirement, do not violate the
requirement of the CAUTION Sign.
Cautions:
Refer to a potential hazard on people or products.

Figure 1 shows the product and the location of safety symbols. These safety symbols mainly include safety
warnings, laser output warnings, and strong electric warnings. All is described in detail as follows:
1.Avoid exposure visible and/or
invisible laser radiation is emitted
from this aperture.
2. Warning: Refer to a potential laser
hazard. The symbol represents laser
radiation. The symbol is pasted on
laser output end.
Table 3 Safety symbols
1.4 Other safety precautions
Do not look directly at the laser output head while the laser is running;
Please strictly follow the product manual to operate the laser, otherwise any damage to the laser will not
be responsible.
2. Product introduction
2.1 Features
Technical advantages: high product qualification rate, and the independent processing capacity for core
components;
Standardization: The production process is highly automated;
Power advantage: the power is more than 10w higher compared with the same specification of other
brands.
Beam quality: Beam quality of all laser tube can reach more than 95% of TEM00.The product
consistency is good.
Long warranty: 12-18 months warranty, most can be used around 3 years, actually.
Advantages of Optical Resonators: The lithographic discharge tube for spatial filtering has been recently
developed, which can improve power and product consistency. With the technology launched, it expands

the leading position in the industry.
Advantages of optical coating: After more than three years of review, the radiation safety license was
successfully applied. Reci is only one nuclear radioactive material coating company in Asia, and the
second in the world. Reci vacuum-deposits the radioactive isotope material from the crucible to the optical
lens. This material has a very low absorption of 10.6um and is irreplaceable.
2.2 Unpacking and inspection
The company has designed specifically a wooden box to ensure that the laser is always protected during
transportation. However, in order to prevent unpredictable situations during transportation, the user still
needs to carefully check whether the package is correctly placed before unpacking, and there is no damage
such as collision, cracking, rain and flooding on the outside of the box. Once you find that there is an
abnormality in the external cabinet, please contact the sales manager in time to deal with it as soon as
possible. After unpacking, please check if the packing list is consistent with the actual items. If you have
any questions, please contact the sales manager in time.

Notice: All paras above only for reference.
3.4 Requirement for Installation
Please follow the above installation diagram. The specialized power supply should be matched with the
specific tube. And the positive electrode carries a high voltage, and the ignition voltage should be reached
to the specific parameters above. If not follow the above, fire, inner tube breakdown and water leakage
will be caused.

3.5 Working Conditions
Water cooling: The cooling liquid is pure water with standard water temperature from 10℃to 50℃. And
the flow rate is 2-5 liters per minute.
Application environment: temperature from 2℃ to 40℃, humidity from 10% to 60%.
Current: The detection current is 28mA. The max operating current must be controlled at 28mA or less.
And the long-term operating current must be controlled at 26 mA or below. Working life can reach 8,000
hours if the current is 24 mA or less. All current above must be based on the actual current of the ammeter
connected in series on the cathode line. The undesired consequences by illegal operation may as below.
Tips: The negative electrode will turn yellowish if long-term overcurrent. What’s more, it will shorten
the life.
Please keep the plastic wrap around the high-pressure jacket to prevent dust from entering the vicinity of
the electrode.
3.6 Working Functions
Working functions include cutting and engraving. Taking engraving as an example, 4mA is recommended
to produce pulse with high frequency under preionization state for better engraving.
3.7 Notices
The surface of beam output lens cannot be scrubbed with any tools such as cotton balls, otherwise the
power will be serious affected. Here are several methods for cleaning.
(1) When the lens is contaminated, do not use the laser tube;
(2) Blow the lens surface obliquely with balloon;
(3) If the above no effect, user needs to remove the lens and use a cotton ball with a little alcohol to rotate
the lens.
(4) No need too much alcohol, but the glue layer of the adhesive lens cannot be touched in case of gas
inside escaping.
(5) The laser cannot be used till alcohol evaporating.
(6) Do not scrub the lens with acetone. The best way to protect the lens is keeping the environment clean.
(7) When testing the beam on plexiglass, please keep it 300mm from the mirror.
3.8 Safety
Goggles are necessary when debugging because the laser belongs to invisible beam. Positive electrode
carries high voltage. By the way, users must pay attention to the safety signs.

3.9 Storage and transportation requirements
The cooling liquid must run out in storage or transportation;
The output must be covered with a dust-proof plastic wrap;
The storage temperature should be kept between 2-40°C and the humidity between 10-60%.
Packing: original package. Be sure to stick the sponge and laser tube with tape to prevent the laser tube
from sliding longitudinally during transportation. The output lens should have a protruding sponge of 70
mm and the reflective lens 50 mm.
