And the operators shall also accept professional training and be qualified to operate the metal laser engraver. This is to avoid incorrect operations during use and increase the service life of the product. The following briefly gives some instructions on how to use the laser metal engraving machine.

1. Steps of starting and turning off machine must be correct

The sequence of starting the laser engraver for metal is as follows.

1) Turn on the general power and the key switch.

2) Wait for 5-10 seconds, press down the button on the control panel.

3) Turn on the power of the galvo scanning system.

4) Turn on the computer and open the engraving software.

5) Adjust the laser power to the working current to start engraving.

The sequence of turning off the machine is on the contrary.

 

2. Cooling system

The operators must start the cooling system before the laser is working. Because the fiber laser will produce a very high temperature when it is working. In addition, when the cooling water quickly flushes the laser tube, the impurities will inevitably be generated. And these impurities will accumulate on the laser tube and affect the cooling effect.

Therefore, it needs to replace the cooling water regularly. The faster the water flow rate, the better the cooling effect.

 

3. Ground protection

The laser power supply and the body of the metal engraving machine must have good ground protection.

This is to ensure the normal operation of the power supply and prolong the service life of the laser tube. Good ground protection can prevent the machine from jumping due to external interference. And it can also prevent accidental circuit damage caused by high voltage discharge.
