When the laser light intensity of a handheld welding machine is unstable, it can be caused by the failure of the following components:
1. **Power Module**:
– **Fault Cause**: The power module voltage is unstable or the power supply is insufficient.
– **Troubleshooting**: Check whether the power input voltage is stable, measure the voltage fluctuation range, and replace the power module if necessary.
2. Cooling System:
– Cause of failure: The efficiency of the cooling system decreases, causing the laser to overheat.
– **Troubleshooting**: Check that the cooling water flow and water temperature are normal, clean the blockages in the cooling water circuit, and replace or repair the cooling system components.
3. Fiber Optic Connector or Fiber Optics:
– Failure Cause: Poor fiber connection or damage to the fiber itself.
– Troubleshooting: Check that the fiber optic connector is securely connected, that the fiber is not damaged or excessively bent, and if there is a problem, replace the fiber or connector.
4. **Protect the lens and focus**:
– **Cause of failure**: There are dust, oil stains or burn spots on the surface of the lens.
– **Troubleshooting**: Clean the lenses regularly, clean them with special lens paper and anhydrous alcohol, and replace damaged lenses if necessary.
5. **Laser**:
– **Failure Cause**: The laser itself is faulty or its performance is reduced.
– **Troubleshooting**: Check whether the laser is working and the indicator light is normal, confirm that the laser has no abnormal alarms, and repair or replace the laser if necessary.
6. **Control System**:
– **Cause of Failure**: The control system is faulty or improperly set.
– Troubleshooting: Check that the parameter settings of the control system are correct, confirm that the control board is not faulty or damaged, and recalibrate or replace the control system if necessary.
7. **Shielding Gas System**:
– **Cause of Failure**: Unstable shielding gas supply or fluctuating air pressure.
– **Troubleshooting**: Check whether the shielding gas supply and air pressure are stable, confirm that the gas valve is working properly, and adjust or replace the gas supply equipment if necessary.
8. **Environmental Factors**:
– **Cause of failure**: Fluctuations in temperature and humidity in the working environment affect the photostability of the laser.
– **Troubleshooting**: Ensure that the temperature and humidity of the working environment are within the specified range of the welding machine, and avoid using the welding machine in an environment that is too high or too low temperature and too high humidity.
Through the above steps, the problem of unstable laser light intensity of handheld welding machine can be effectively diagnosed and eliminated, and the welding quality and normal operation of the equipment can be ensured.
