Benefits of our lasers?
Lasers Designed Specifically for Engraving & Cutting-Lasers are made in China with high quality and specifically tuned to provide fine cutting and engraving quality.
Power Range Availability (30-180 watts)-Get the exact amount of power you need for virtually any application.
How much power do I need?
25-35 Watts – It is special for stamp carving and simple engraving and thin material cutting, not recommended for thick cutting or dual head applications.
40-50 Watts – Medium production power level for deeper, high speed engraving and slightly thick cutting operations.|
60-80 Watts – High production power level provides increased throughput, deep engraving and cutting. Ideal for precision engraving and cutting.
100-180 Watts – Very high production power level that is ideal for heavy cutting and deep, higher throughput engraving. For example, if you want to cut acrylic of thickness of over 3mm (include 3mm); you can choose high power lasers.
Using conditions of laser tube
1. Ambient temperature: 10-40
2. Relative humidity: 45%-85%
Cooling conditions
1. Cooling water temperature: 15-30 in summer, in other seasons 20 is better.
2. Cooling water flow rate: Above 6L / min;
3. Water quality: Drinking water and impurities is less than 0.2mm in diameter;
4. Cooling water PH value: 6-9.

Operating Instruction of Co2 Laser Tube

Installation Requirement
1. Make sure to follow the operation instructions of model S8 as shown in the illustration. The dedicated power DY20 should be equipped. The positive pole is in high voltage (The ignition voltage is 30kv). It may cause the following consequence when it is failed to follow the instruction: Arcing; the inner tube will be punctured by electricity and may cause water leakage.

2. Operation conditions

• Water cooling: using purified water; 3 to 5 liter/minute; water temperature: 10℃-40°C.
• The operating environment: temperature 2-40°C, humidity 10-60%.
• The working current: Test current is 29mA. Maximum working current is 32mA. The running current must be kept below 30mA. The life span can reach 10,000 hours if the current is kept below 28mA. The ammeter indicating current must be connected to the negative electrode of the laser tube.
• When it is working under over-high current for long term, the negative pole will appear purple, and the life span will be reduced rapidly.
• To protect dust from going into the insulation sheath, please wrap it with plastic film.

3. Working Performance 

• Cutting function.
• Engraving function: Very good, when the working current is 4mA and the tube is in the state of preionization, the laser can be used for high-frequency impulse engraving.

4. Key Notes 

Do not clean the exterior surface of the output widow mirror with tools such as tampon; otherwise the output power will be seriously affected. The followings are the designated methods to clean up pollution in the exterior surface of window mirror:
1) When the mirror is polluted, do not turn on the laser.
2) Blow the mirror surface sideway with air blower.
3) Spray the pure alcohol on the mirror surface with sprayer.
4) Turn on the laser after the alcohol gets fully volatilized.
5) If the methods above don t work effectively, it is necessary to ask for the professional to use tampon with alcohol to clean the mirror surface from middle to edge. The best solution is to prevent the window from being polluted.
It is forbidden to clean the mirror with acetone.
The screw in the front and back ends of the laser tube is not allowed to be moved, otherwise the out power will be declined and even the tube may be scrapped.
Put the acryl 300mm far away from output mirror, when testing the laser spot.

5. Safety 

The laser beam is invisible light. Please wear protective glasses when debugging the laser. The positive pole is in high voltage. Pay attention to the security marks.

6. Storage and Transportation Requirement 

Pour out cooling fluid in the event of storage and transportation, and cover the output terminal with a dust-proof plastic bag. The storage environment is 2-40°C, and the requested humidity is 10-60%. Pack the laser as in the original way.
Important notes: It is requested to cement the sponge together with laser tube to prevent the tube vertically sliding during transportation. The sponge in the side of output mirror must be 70mm beyond it, and the sponge in the side of reflecting mirror must be 50mm wider.
