When the red light system of the handheld welding machine does not display properly, you can check it by following the steps below to determine the problem:
1. **Check the power supply**:
– **Step**: Use the multimeter to measure the power input voltage of the red light indicator and confirm that the voltage is stable within the specified range.
– **Method**: Check whether the power cord of the welding machine is firmly connected to make sure it is not damaged or loose. If the voltage is unstable, the power module needs to be replaced or repaired.
2. **Check for Red Light Indicator**:
– **Step**: Check for damage or abnormality in the red light indicator itself.
– **Method**: Observe whether the indicator light of the red light indicator is lit up and confirm its working status. If the red light indicator is damaged, the red light indicator will need to be replaced.
3. Check Control System:
– Steps: Check the settings of the control panel and the status of the control board.
– Method: Make sure the red light feature is enabled on the control panel. Inspect the components on the control board for visible signs of damage or burnout, and replace or recalibrate the control board if necessary.
4. **Check the fiber connection**:
– **Steps**: Check that the fiber connection is stable and that the fiber is not damaged or excessively bent.
– **Method**: Confirm that the fiber connector is tightly connected and that the fiber is not visibly damaged. If there is a problem, the fiber or connector needs to be replaced.
5. **Check the lens and optical path**:
– **Step**: Check 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 damaged or heavily contaminated, they need to be replaced.
6. **Check the laser**:
– **Steps**: Check the working status of the laser and confirm if the laser is operating normally.
– **Method**: Check the laser’s indicator light and display for abnormal alarms. If the laser fails or does not work properly, it needs to be repaired or replaced.
7. **Check the air pressure system**:
– **Step**: Check that the shielding gas supply and air pressure are normal.
– Method: Make sure the air pressure is within a reasonable range and confirm that the air valve is opened normally. If there is a problem, the gas flow will need to be adjusted or the gas supply equipment replaced.
8. **Test the red light function**:
– **Steps**: Test the red light function and observe whether the red light is displayed normally.
– **Method**: Under the condition of ensuring safety, turn on the red light function for testing. If the red light still does not appear, more in-depth inspection and repair may be required.
Through the above steps, the problem of no red light display of the handheld welding machine can be effectively diagnosed and eliminated. If the problem persists, it is recommended to contact technical support for a more in-depth inspection and repair.
