The laser marking machine will inevitably fail during use. What if the laser marking machine cannot produce laser? So what are the exclusion methods for the fiber laser marking machine not to emit light:
1. In the parameter setting of the laser marking machine, check whether the laser type is correct. It is one of the main reasons for the failure of continuous lighting.
2. Pull the control line of the nine cores of the laser marking machine, and test to observe whether the control line is loose and the connection is unreliable.
3. Remove the control wire on the power supply of the laser marking machine, that is, the nine-core wire. Then, according to the burst button of the laser power supply, it can be judged whether the power supply or the motherboard is faulty.
4. If the shot is normal, it means that the power supply of the laser marking machine is normal and there is no fault.
5. If the shot is not normal, it means that there is a problem with the power supply.
