During the use of fiber laser cutting machine, occasionally encounter the situation that the laser cutting machine does not emit light. When this kind of failure occurs, first check the machine. You can follow the following steps:
1. Check if the water circulates normally, if the water protection is broken, you can short-circuit the water protection and use it.
2. Pre-adjust to see if the ammeter is oscillating. If it does not oscillate, check whether the laser power supply has 220v power supply. If there is power supply but no light, the power supply may be faulty and need to be replaced.
3. Test whether the water protection is normal. Short-circuit +5v and AIN to check the maximum output power. If light comes out, the potentiometer is broken and needs to be replaced.
4. If there is a noise in the laser power supply, it is generally because the power connector is in poor contact and needs to be re-welded or connected.
The laser cutting machine does not emit light when it is turned on
1. Check whether the laser power switch of the machine is on;
2. Check whether the chiller is turned on, and check whether the light output signal, control signal and water protection signal of the chiller are normal;
3. Check whether the laser light path is normal, press the light to check whether the laser tube is bright, and the laser head is not light because there is a problem with the light path;
4. Check whether the button panel lights are normal, check whether the machine operation panel, power or computer software parameters are correct;
5. Check whether light is emitted from the laser power signal. If the light is emitted, the laser tube and laser power supply are normal; if there is no light, the laser power supply is broken, and the power supply needs to be replaced.
6. If the voltage lower than 200V.
The laser cutting machine does not emit light during operation
1. Check whether the water tank of the fiber laser cutting machine alarms.
(1) If an alarm occurs, connect the water inlet and outlet of the water tank with a water pipe, and power on the water tank to see if it alarms.
If you call the police, the water tank is broken. If there is no alarm, the fiber laser cutting machine's water path is not unblocked.
Check whether the water pipe is bent or other problems, and check whether there is any debris in the water tank.
(2) If there is no alarm, check whether the power supply fan of the fiber laser cutting machine is rotating.
2. Whether the fiber laser cutting machine emits light.
(1) When light is emitted, the wire on the motion control card is loose, or the motion control card is broken and the board needs to be replaced.
(2) No light is emitted, and the laser power supply is broken. The power supply fan of the fiber laser cutting machine does not turn, use an electric pen to test whether the laser power supply 220V port has electricity.
There is electricity, the laser power supply is broken and needs to be repaired or replaced. If there is no electricity, check the power switch and wiring of the fiber laser cutting machine.
