When marking the workpiece, the laser marking machine mainly emits the laser through the fiber laser, then transmits it to the high-speed scanning galvanometer through the fiber transmission device, and then integrates a beam to achieve the marking function of the workpiece. The photoelectric conversion of laser marking machine has a high conversion ratio. The laser marking machine can be used to mark some metal materials and non-metallic materials. Its application fields are mainly high precision marking workpieces. Some problems often occur when the laser marking machine is working, which makes the marking work unable to be carried out normally and affects the marking efficiency. Let's talk about the causes of two common faults of laser marking machine:

Field operation of laser marking machine

1、 The air switch of the laser marking machine trips.

Cause 1. Check whether there is high voltage in the ignition device of the laser marking machine.

Cause 2. Check whether the output power of the laser marking machine is within the rated range.

Cause 3: The main circuit components of the laser marking machine are faulty or damaged.

2、 The chiller does not work.

Cause 1. Check whether the circuit of the chiller of the laser marking machine is faulty.

Cause 2. Check whether the input voltage of the chiller of the laser marking machine is within the proper range.

Cause 3. Check whether the chiller of the laser marking machine is damaged.
