After buying a laser welding machine, many customers have questions about how to turn on the welding machine. Only three parts are needed: 1. Check before starting; 2. To see if there is a “condensation” phenomenon; 3. Check the output spot.;4.Check the purity of the cooling water.
Check before starting
In order to ensure that the laser welding machine is always in normal working condition, after two weeks of continuous work or when it is not used for a period of time, the components in the optical path such as YAG rod, dielectric film, and lens protection glass should be checked first before starting to determine the optical components. There are no abnormal phenomena such as dust pollution and mildew. If there are any such phenomena, they should be dealt with in time to ensure that the optical components will not be damaged under strong laser irradiation.

To see if there is a “condensation” phenomenon
In high temperature or humid environment, the laser welding machine should always pay attention to observe whether there is “condensation” caused by low water temperature on the cooling water circulating pipe or laser concentrating cavity. The occurrence of “condensation” will cause damage to the end face of the YAG crystal, resulting in a decrease in output power and even failure to emit light. Be careful during use.
Check the output spot
The operator can often check the output spot of the laser welding machine with black photo paper. Once spot unevenness or energy drop is found, the resonant cavity should be adjusted in time to ensure the beam quality of the laser output.

Check the purity of the cooling water
The purity of the cooling water is the key to ensuring the laser output efficiency of the welding torch and the life of the laser concentrating cavity components. During use, the conductivity of the internal circulating water should be checked once a week, and the internal circulating deionized water must be replaced once a month. Always pay attention to the color change of the ion exchange column in the cooling system Once the color of the resin in the exchange column has changed to dark brown or even black, the resin should be replaced immediately.
The operation of any machine makes perfect. When we use the laser welding machine, as long as we have a good grasp of the matters that should be paid attention to in the use process, I believe everyone can use the laser welding machine more quickly and put it into work better.
