1. The laser die cutter power supply is unstable (preferably separate power supply)

2. Laser die cutting machine does not have a grounding wire (the probability of burning the machine without a grounding wire is very high)

3. The water cooling cycle on laser die cutter is not good (when the water temperature is overheated, not only the life of the laser tube will be shortened, but also the laser power supply)

4. The laser tube and laser power supply on laser die cutting machine do not match.

5. Laser tube sealing is not good (dust if the accumulation of too much on the laser tube will form static electricity, which may also affect the life of the laser power supply)

6. Improper operation (often when the power is turned on to 100% will also have an impact, it is recommended to control the power up to 85% or so for laser die cutter)

Regarding the failure of the power supply, several suggestions are for your reference:

Laser die cutter must have a good safety ground, it is very important; Dust is a major cause of damage to electronic components. It is recommended that you clean the laser power supply at regular intervals (about 5 months); Moisture is also a major cause of laser power failure, especially in summer.
