    New laser machine Cracking sound, found the problem I think - need advice

    Hi Guys,

    I have a new laser machine from China (150w OLT1390) and have been using it over the past month or 2. Everything has been working fine except I heard some craking/sparking noises coming from the machine when I was engraving at 20% power. I had heard this once before a while ago but then it dident happen again.

    This time it dident stop and then the laser stopped engraving. I stopped the machine to investigate and think I have found the cause. I think it is the High Voltage connector on the laser cable going from the PSU to the Laser. there was a smaller cable sitting underneath the connector which has charred and when i opened tht connector I could clearly see burn marks.

    I have attached some photos.

    I have contacted the manufacturer , but in the meantime what do you guys think, is my laser tube likely to have been damaged also?

    Also is there a good source in the UK I could get a better quality Single Core, High Voltage connector to replace the current one?

    Thanks,

    Hi, To confirm whether your tube has been damaged, please have a reference of this video.

    Laser tube problem or Laser powersupply problem - YouTube

    Just ask your supplier to replace the parts to you. It should be covered within aftersales service.
