How to Maintain the Handheld Laser Welding Machine?

The handheld laser welding machine is a new generation of laser welding equipment, which belongs to non-contact welding. Compared with traditional welding, laser welding has a higher energy density. So it can achieve better welding results. However, in daily life, we can not ignore the maintenance of the machine. Comprehensive maintenance work can make it last longer. Next, let’s learn about the maintenance of hand-held laser welding machines.

Regular inspection

Operators should regularly check the following aspects:
1. Check whether the cooling fan rotates smoothly when the power is turned on;
2. Check for gas leakage;
3. Check whether there is looseness or peeling between the welding wire connector and the insulation;
4. Check whether the welding cable and each wiring part have abnormal heating. 

Internal dust cleaning

Since the hand-held laser welding machine is air-cooled, it is easy to suck the surrounding dust into the body. The operator should regularly use compressed air to blow off the dust inside the welding machine. Especially in transformers of equipment, gaps between coils, power semiconductors, etc.

Parts Repair or Replacement

Long-term use will deform the shell of the machine due to collisions, and the internal parts will also wear out. Therefore, during regular inspections, the operator should replace defective parts in time. The shell and damaged insulation parts should be comprehensively repaired. If there is rust, the operator should make the welding machine conduct electricity well by removing the rust. These measures can ensure better performance of the laser welding machine.


To sum up, for laser welding machines, regular maintenance, and inspection are essential. Doing so reduces the occurrence of welding accidents and ensures the safety of the operator. And it also increases the life of the handheld laser welding machine.In particular, the operator of the machine must receive professional training and familiar with basic equipment knowledge.
