Hi all,
My ULS 25ER seems to be losing power. This morning I was cutting 1/8" lite plywood and while I was watching the intensity of the beam seemed to dim and the cut line got thinner. I have seen this happen with wood that had density variations and this could be the case here except that my test is to see if light will pass through the wood. This wood does pass light from a 25W fluorescent bulb.
I have heard that the laser tube will fail eventually and my laser has been running for a year and supposedly was recharged by the former owner perhaps a year prior. So I suppose that it might be the cause. However, I also read that the laser when it goes down, it is an all or nothing situation. Mine will still fire but at 1/3rd the power.
The laser tube power supply would be my next source for checking. I read that it can fail slowly.
I read that sometimes the power supply can overheat and not provide the power necessary so I turned off the unit and will wait an hour then retry cutting. However, if this does fix the problem, should I have the power supply repaired or is this normal? I was cutting continuously for 4 hours and the ambient temps were ~65F.
My question is just how do I diagnose what is happening?
