When the laser light of the handheld welding machine does not shine, you can troubleshoot by following the steps below to check the laser source and optical path:
1. **Check Power & Connections**:
– Confirm that the power supply of the welding machine is properly connected and the voltage is stable.
– Check that all cables are secure and not loose or damaged.
2. **Check Control Panel Settings**:
– Confirm that the laser enable switch on the control panel is turned on.
– Confirm that there are no unusual alerts on the dashboard.
– Check that the trigger signal and the safety lock signal on the control panel are working properly (should be shown green).
3. **Check Laser Status**:
– Confirm that there are no faults or alarms on the laser itself, check the indicator light and display on the laser.
– Confirm that the laser is not overheating or overloaded, and if necessary, allow the laser to cool down for a period of time.
4. **Check the Water Cooling System**:
– Confirm that the water cooler is working properly and that the water temperature and water flow are within the normal range.
– Check that the water cooling line is clear and that there are no blockages or leaks.
5. **Check the Air Pressure System**:
– Confirm that the shielding gas supply is normal and that the air valve is open normally.
– Confirm that the air pressure is within the normal range and that there are no cases where the air pressure is too low or too high.
6. **Check the lens and optical path**:
– Check that the protective lens is clean and has any burn points or other damage on the surface, and replace it immediately if necessary.
– Confirm that the optical path is not blocked and that all optical components (e.g., focusing lenses, mirrors) are installed correctly and cleanly.
– Check that the fiber connection is secure and that the fiber is not bent or damaged.
7. **Perform the test**:
– When it is safe to do so, do a simple light test and see if there are any changes.
– If the laser still does not shine, it is recommended to contact technical support for more in-depth inspection and repair.
