Power supply precautions and fault detection methods of laser cutting machine

Laser cutting machine power use precautions

Laser cutting machine in the process of use, to the various components of the equipment for good maintenance, to ensure the normal operation of the machine. Laser power supply is one of the most important parts in laser cutting machine equipment, improper use is easy to cause damage to the power supply, affect the normal production. How to use to maximize the life of the power supply?

First of all, laser cutting machine in cutting, as far as possible in accordance with the parameters of the cutting table to set, such as cutting speed, thickness, so as not to exceed the standard range, damage the normal service life of the power supply; The machine should be cleaned and maintained regularly to reduce the operating pressure of the machine; Before each cutting, check the machine to see if the ground is good, to ensure that the power supply is fully used. Try not to hang for a long time arc and perforation, in order to improve the service life of wearing parts. If the external voltage is unstable, a voltage regulator should be equipped accordingly to ensure a stable voltage supply.

Operators in the process of operation, careful maintenance and proper use, in order to ensure the normal operation of the machine, to ensure the quality of cutting. Of course, when we choose laser power, we must choose a good reputation, the market generally recognized laser power brand.

Laser cutting machine common failure and solution

1, boot without any reaction

Whether the power fuse is burnt out: Replace the fuse.

Power input is normal: Check the power input and make it normal.

Whether the main power switch is damaged: Replace the main power switch.

2, no laser output or laser is very weak

Whether the optical path is offset: Adjust the optical path carefully.

Whether the reflector is contaminated or damaged: Clean or replace the reflector.

Whether the focal length of the device changes: Adjust the focal length.

Whether the focusing mirror is contaminated: Clean the focusing mirror.

Whether the cooling water quality or temperature is normal: replace the clean cooling water so that the temperature is normal.

Whether the cooling water circulates: dredge the cooling waterway.

Whether the laser tube is damaged or aged: Replace the laser tube.

Whether the laser power supply is powered on: Check the power supply loop of the laser power supply to make it normal.

Whether the machine temperature is too high: 1. Shut down the temperature to fall; 2. Ventilation to enhance the heat dissipation of the machine; 3. Adjust the ambient temperature.

Whether the laser power is damaged: Replace the laser power.

3, cutting/engraving depth is not ideal

Whether cutting/engraving processing parameters are normal: Set appropriate processing parameters.

Laser power setting is normal: The laser power is set correctly.

Before using the power supply, we should first check to see if the power supply is damaged in the process of transportation. If it is damaged, we need to replace the power supply with the manufacturer. If there is no damage, we should see whether the parts of the power supply are complete, and there is no debris inside the audio shell.

When in use, ensure that the power supply is properly grounded. Otherwise, high voltage faults may occur, which may endanger human life. When connecting the input power cable, please turn off the switch of the laser power supply first. The power cable used must be a three-connector power cable; otherwise, the normal operation will be affected.

When the power supply is working, do not touch the high voltage output line and high voltage connection terminal of the power supply. Otherwise, your life will be endangered. If you want to replace the power supply, turn off the power supply and replace it only after the power fan stops completely.

The power supply must be used in the working environment of strong wind refrigeration. It must be remembered that as long as there is a high voltage output on the power supply, the personnel must not approach the high voltage part to prevent electric shock. And we in the choice of laser cutting machine power supply, to choose a regular manufacturer.
