When the laser of the handheld welding machine does not shine, the following parts may need to be replaced to solve the problem:
1. **Protective Lenses**:
– If there are burn spots or severe contamination on the surface of the protective lens, it may block the normal output of laser light. Protective lenses need to be inspected and replaced.
2. **Focusing Lens**:
– If the focusing lens is damaged or heavily contaminated, it will also affect the light output effect of the laser light. Inspect the focusing lens for damage or contamination and replace it if necessary.
3. **Laser**:
– If the laser itself is faulty or not working properly, check the laser’s indicator and display for abnormal prompts. If the laser fault is confirmed, the laser needs to be replaced.
4. **Cooling System Components**:
– If the cooling system is not working properly, it may cause the laser to overheat and stop working. Check whether the water pump, water cooler and other components in the cooling system are working properly, and replace the damaged parts if necessary.
5. **Power Module**:
– If the power module is damaged, it may cause the entire welding machine to fail to supply power properly. Check whether the power module is working properly, if it is faulty, you need to replace the power module.
6. **Control Board**:
– A malfunction of the control board may also cause the laser not to shine. Inspect the components on the control board for visible signs of damage or burnout, and if so, need to replace the control board.
7. **Fiber Optic Connectors**:
– If the fiber optic connector is damaged or poorly connected, it will affect the transmission of laser light. Inspect the fiber optic connector for physical damage or loose connections, and replace the fiber optic connector if necessary.
8. **Safety switch and ground lock**:
– If the safety switch or ground lock signal is abnormal, the laser will not be able to emit light. Check and replace the problematic safety switch or floor lock.
