Common faults and problems of laser rust removal machine

During the use of laser rust removal machines, various common problems may be encountered, which can be summarized as follows:

1、 Optical path and laser source issues
Fiber aging or damage:
Phenomenon: After a period of use, optical fibers are prone to aging, leading to a decrease in power and signal attenuation, which affects the rust removal effect.
Solution: Check if the optical fiber is broken or damaged, and replace it with a new one if necessary.

Spot deformation:
Phenomenon: Irregular spot shape leads to uneven rust removal on the surface of the workpiece.
Reason: Misalignment of optical path, dirt on laser lens, etc.
Solution: Before use, carefully check the optical path and lens, adjust and clean them in a timely manner.

Laser malfunction:
Phenomenon: The laser alarm indicator light is on and cannot work properly.
Solution: Check the specific cause of the alarm through the communication interface provided by the laser or the mobile app, and contact or professional technicians for repair or replacement.

2、 Lens contamination and condensation
Lens contamination:
Phenomenon: Dust or impurities adhere to the lens, affecting the laser transmittance and even burning the lens.
Solution: Regularly inspect and clean the lenses, especially to protect them. Use gases such as nitrogen and argon to blow and avoid using compressed air (as particles and moisture in the air may harm the lenses).

Lens condensation:
Phenomenon: In environments with high humidity, condensation forms on the surface of the lens, resulting in reduced transparency.
Solution: Improve the working environment, such as indoor work, using air conditioning, etc., to reduce humidity. Meanwhile, choose a laser rust removal machine with stronger adaptability to humidity.

3、 Control system and power supply issues
Control system malfunction:
Phenomenon: Control program error or malfunction, causing the laser rust remover to malfunction.
Solution: Notify professional maintenance personnel in a timely manner to solve the problem and ensure the normal operation of the control system.

Power issue:
Phenomenon: The power cord is loose or detached, causing the laser rust remover to fail to start or operate unstably.
Solution: Check if all connecting wires and interfaces are secure to ensure a stable power supply.

4、 Cooling system issues
Cooling system malfunction:
Phenomenon: The cooling system fails, causing the laser temperature to be too high, affecting the laser output effect and even damaging the laser head.
Solution: Regularly check whether the cooling system is working properly, including power connections, fuses, and the cleanliness of the condenser and evaporator. If necessary, promptly repair or replace the cooling system.

5、 Other common questions
Fiber optic cable bending:
Phenomenon: Excessive bending of fiber optic cables leads to fiber optic damage.
Solution: Avoid bending the fiber optic cable too much during work, and the bending degree should not be less than 30 centimeters in diameter.

Panel switch malfunction:
Phenomenon: Some switch buttons on the panel are malfunctioning.
Solution: Replace the switch button with a new one and pay attention to the welding quality during installation.

Laser tube high-voltage plug issue:
Phenomenon: The high-voltage plug of the laser tube ignites, falls off, etc.
Solution: After turning off the main power, clean the burnt part on the plug and reconnect it to the laser tube. Simultaneously use insulating tape for insulation treatment to prevent short circuits.
