Question #: 6917

Question: Hello - I have had some years of good use from my Blacktooth CN Laser, but had to reduce the speed on jobs over the last year to get satisfactory cutting. Recently, on a long job, the laser beam weakened and disappeared entirely over about 30 seconds (guess). I fixed a new tube, but this won't fire either. How can I safely test the output lead to see if it's dead or partially so?

Current Solution

It is most common for the laser tube to go out, after about 1000 hours of work time!
It is strange that the new laser tube will not fire!
We would recommend to check the tungsten leads, if they are making good contact!

Also here is a link to a instructables page where they have tested a laser power supply!
