When the laser light of the handheld welding machine fluctuates, the common maintenance or adjustment methods include the following aspects:
1. **Check and replace the power module**:
– **Steps**: Use a multimeter to measure the voltage of the power supply input and output to confirm that the voltage is stable.
– Method: If the voltage is unstable, the power module needs to be replaced. Ensure that the new power module meets the specifications of the welding machine.
2. **Cleaning and Replacing Lenses**:
– **Steps**: Inspect the protective lenses, focusing lenses, and mirrors for dust, oil, or burn spots.
– **Method**: Clean the lenses with special lens paper and anhydrous alcohol. If the lenses are burned or damaged, they need to be replaced.
3. Inspect and service the cooling system:
– Steps: Check the cooling water flow and water temperature to ensure that the cooling system is functioning properly.
– **Method**: Clean the blockage in the cooling water pipe and check the operating status of the water pump and water cooler. If the cooling system component is damaged, it needs to be replaced or repaired.
4. Inspect and Replace Fiber Optics & Connectors**:
– Steps: Check if the fiber connection is secure and if the fiber is damaged or over-bent.
– Method: Make sure that the fiber connector is tightly connected and that there is no visible damage to the fiber. If there is a problem, the fiber or connector needs to be replaced.
5. **Check the laser**:
– **Steps**: Check whether the working status and indicator light of the laser are normal, and confirm that there is no abnormal alarm for the laser.
– **Method**: If the laser has an abnormal prompt or is not working properly, the laser needs to be repaired or replaced.
6. **Adjust the control system**:
– **Steps**: Check the settings of the control panel and the working status of the control system.
– Method: Recalibrate the control system by making sure all parameters are set correctly. If the control board is faulty, the control board needs to be replaced.
7. **Check the shielding gas system**:
– **Steps**: Check that the shielding gas supply is stable and the air pressure is within a reasonable range.
– Method: Confirm that the gas valve is working properly, adjust the gas flow rate or replace the gas supply equipment if necessary.
8. **Adjust the working environment**:
– **Step**: Check the temperature and humidity of the working environment to ensure that it is within the specified range of the welding machine.
– **Method**: Avoid using the welding machine in an environment that is too high or too low temperature, too high humidity.
These methods can help solve the problem of laser light fluctuating in handheld welding machines. If the problem persists, it is recommended to contact technical support for a more in-depth inspection and repair.
