4. The current problem of the marking machine Solution: If the current of the device's power supply is too small, it can also affect the depth of the marked text. At this time, it is necessary to increase the current of the laser power supply, reduce the frequency of the marking machine, so that the marking machine can operate normally and avoid the situation where the marked text is too shallow.
