When the laser power of the handheld welding machine gradually declines, the possible causes and corresponding troubleshooting methods are as follows:
1. **Lens Contamination or Damage**:
– **Cause**: Dust, oil, or burn spots on the protective lenses, focusing lenses, or mirrors can cause laser power degradation.
– **Troubleshooting**: Clean and inspect the lenses regularly, and replace damaged or heavily contaminated lenses if necessary.
2. **Cooling System Efficiency Decrease**:
– **Cause**: Cooling System Efficiency Degradation can cause the laser to overheat, affecting power output.
– **Troubleshooting**: Check whether the cooling water channel is smooth, whether the water pump, water cooler and other components are working properly, and replace or repair the cooling system parts if necessary.
3. **Laser Aging**:
– **Cause**: Lasers may age after a period of use, resulting in a gradual decline in power.
– **Troubleshooting**: Check the operating hours and status of the laser, and if the laser is confirmed to be aging, consider replacing the laser.
4. Fiber Connection Issues:
– Cause: Damage to the fiber connector or the fiber itself or a poor connection can cause power degradation.
– Troubleshooting: Check fiber connectors and fibers for physical damage or looseness, and replace fibers or connectors if necessary.
5. **Power Issue**:
– **Cause**: Unstable power supply or power module failure will affect the stability of the laser power.
– **Troubleshooting**: Check whether the power supply is normal, whether the voltage is stable, and replace the power module if necessary.
6. **Air Pressure Problem**:
– **Cause**: Insufficient supply of shielding gas or unstable air pressure can affect the welding effect and laser power.
– **Troubleshooting**: Check that the shielding gas supply and air pressure are normal, and adjust or replace the gas supply equipment if necessary.
7. **Control System Problem**:
– **Cause**: Failure or improper setting of the control system can cause abnormal laser power output.
– **Troubleshooting**: Check the settings of the control panel and the working status of the control system, make sure all parameters are set correctly, and recalibrate or replace the control system if necessary.
8. **External Environmental Factors**:
– **Cause**: Factors such as temperature and humidity of the working environment will also affect the efficiency of the laser.
– **Troubleshooting**: Ensure that the working environment meets the requirements for the use of the welding machine, and avoid using the equipment in an environment that is too high or too low temperature and too high humidity.
