There may be several direct reasons why the welding machine suddenly does not shine:
1. **Power Issue**: Check whether the power supply is normal, including whether the voltage is stable and whether the grounding is good.
2. **Controller Signal Problem**: Confirm whether the signal of the controller is normal, especially whether the welding head light switch and the safety lock signal are displayed in green.
3. **Laser Problem**: Check the laser itself for abnormal alarms or faults, such as overheating inside the laser or other abnormal states.
4. **Water cooling system problem**: Confirm whether the water cooler is operating normally, whether the cooling channel is smooth, and whether the water temperature and water flow are within the normal range.
5. **Air pressure problem**: Make sure that the air pressure is normal, whether the shielding gas supply is stable, and whether the air valve is opened normally.
6. **Lens Problem**: Check that the protective lenses are clean, if there are any burn points or other damage, and if necessary, replace the protective lenses.
If none of the above checks find any problems, it is recommended to contact technical support for more in-depth diagnosis and repair.
