To quickly confirm the laser power degradation issue of the handheld welding machine, you can check and troubleshoot it by following these steps:
1. **Inspect the lenses**:
– **Steps**: Inspect the protective lenses, focusing lenses, and mirrors for contamination or damage.
– **Method**: Clean the lenses with special lens paper and anhydrous alcohol, replacing damaged lenses if necessary.
2. **Check the cooling system**:
– **Steps**: Check whether the cooling water channel is unobstructed and whether the water cooler and water pump are working properly.
– **Method**: Ensure that the flow and temperature of the cooling water are within the normal range, check the inlet and outlet lines of the water cooler for blockages or leaks, and replace the relevant parts if necessary.
3. **Check Fiber & Connector**:
– **Step**: Check the fiber and fiber connector for damage or poor connection.
– **Method**: Confirm that the fiber connector is securely connected and there is no visible damage, and replace the fiber or connector if necessary.
4. **Check the Laser**:
– **Steps**: Check the working condition and service life of the laser.
– **Method**: Check the indicator light and display of the laser for abnormal prompts, and consider replacing the laser if the laser is out of service life or displays an abnormal alarm.
5. **Check the power supply**:
– **Steps**: Check whether the power supply of the welding machine is normal and whether the voltage is stable.
– **Method**: Use a multimeter to measure the voltage and current of the power outlet, confirm that the power supply is stable, and replace the power module if necessary.
6. **Check the air pressure system**:
– **Steps**: Check that the shielding gas supply and air pressure are normal.
– Method: Make sure the air pressure is within a reasonable range, check that the air valve is open properly, and adjust or replace the gas supply equipment if necessary.
7. **Check the control system**:
– **Steps**: Check the settings of the control panel and the working status of the control system.
– Method: Make sure all parameters are set correctly, check the control board for obvious damage or anomalies, and recalibrate or replace the control system if necessary.
8. **Perform Test Welding**:
– **Steps**: Perform a test weld to see if the laser power output is stable.
– **Method**: Select a standard welding material, perform a simple welding test, and observe whether the welding effect and laser power output are stable.
These steps can help you quickly identify laser power degradation issues with your handheld welding machine and find possible solutions. If the problem persists, it is recommended to contact technical support for further inspection and repair.
