As Christmas approaches, many factories will shut down. When the laser cutting machine is not used for a long time, some problems will occur. Therefore, when returning to work and using a laser cutting machine, the following points should be paid attention to:
1. Preparation before the test
(1) Cut off the connecting cable between the laser generator and the instrument body to ensure a good connection.
(2) Open all the water inlet and outlet valves of the chiller to ensure that the water pump is closed to avoid noise when the water pump is running.
2. Check system and maintenance
power supply system
(1) Power supply line: no serious bending, no damage, no disconnection;
(2) Power cord connection: press the plug to ensure a firm connection;
(3) Control signal line: The interface connection is firm and there is no looseness.
Air supply system
Gas path: no damage, no blockage, good air tightness;
Tighten the joints of each gas pipeline to ensure that the connection is firm and smooth;
Use compliant gases as specified by the equipment manufacturer.
The pressure of industrial gas cylinders should not be lower than the maximum working pressure of the equipment used.
The gas supply system should be kept clean to prevent foreign matter from entering.
3. Equipment operation test
Preparations before powering on the device
(1) Confirm that the water temperature of the chiller has reached the set temperature;
(2)
Turn on the power switch of the laser processing system. After the laser is powered on, the POWER indicator on the laser panel will light up.
(3) Turn off the laser power switch and turn on the protection function.
(4) Confirm that all control buttons of the laser processing system have been reset.
(5) Simple maintenance of the laser: turn off the cooling fan and exhaust fan; turn on the cooling motor;
