When the handheld welding machine does not display the red light of the light guide, it may be caused by the following reasons, and the corresponding troubleshooting steps can be taken:
1. **Power Supply Issue**:
– **Cause**: The red light indicator has an unstable power supply or insufficient power supply.
– **Troubleshooting**: Check whether the power connection of the welding machine is stable and whether the voltage is stable. If there is a problem with the power supply, the power module needs to be repaired or replaced.
2. **Red Light Indicator Failure**:
– **Cause**: The red light indicator itself is damaged or the internal circuit is faulty.
– **Troubleshooting**: Check the status of the red light indicator and if the indicator light is normal. If the red light indicator is damaged, the red light indicator will need to be replaced.
3. **Control System Problem**:
– **Cause**: The control system is not properly set up or the control board is faulty, resulting in the red light cannot be displayed normally.
– Troubleshooting: Check the settings of the control panel to make sure the red light feature is enabled. Confirm that the control board is not faulty or damaged, and recalibrate or replace the control board if necessary.
4. Fiber Connection Problem:
– Cause: Poor fiber connection or damage to the fiber itself, resulting in red light not being transmitted.
– Troubleshooting: Check that the fiber optic connector is securely connected and that the fiber is not damaged or excessively bent. If there is a problem, the fiber or connector needs to be replaced.
5. **Lens Problems**:
– **Cause**: Dust, oil, or burn points on the protective lenses or focusing lens may block red light.
– **Troubleshooting**: Clean protective lenses and focusing lenses using special lens paper and anhydrous alcohol. If the lenses are damaged, they will need to be replaced.
6. **Laser Problem**:
– **Cause**: The laser itself is faulty or degraded in performance, causing the red light to not work properly.
– **Troubleshooting**: Check whether the laser is working and whether the indicator is normal, and confirm that the laser has no abnormal alarms. If necessary, repair or replace the laser.
7. **Barometric System Problem**:
– **Cause**: Insufficient supply of shielding gas or unstable air pressure, which may affect the display of red light.
– **Troubleshooting**: Check whether the shielding gas supply and air pressure are normal, confirm that the gas valve is working properly, and adjust or replace the gas supply equipment if necessary.
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.
