Hi guys,
I have a Laser Pro 100W with a Synrad tube and it is loosing power if I run a 20-30 minutes job on it. I do not believe it is a beam alignment or dirty lens/mirror issue because I check them regularly and clean them. Even the ones that located at the bottom under cover where it is combined with a red beam. I have checked all fans that cool the tube and found that one was not working. But there are a lot of them and that one does not even blow at the tube, more like above it. I cleaned it but I do not believe it will fix the problem.
What else could it be?
I do not think it is a tube problem as the laser is only 5 years old and I do not think it's been made more than 2000-3000 hours. Power level was checked a year ago during some maintenance by a distributor tech. He told me it is still strong. I am going to check it myself once I receive a power meter but I do not think I will find something considering that power degrades only after a long job.
To get an idea how it degrades, when I turn it on in the morning I can cut 6mm MDF with 2% speed and 100% power, then if I run 20 mins job after 4-7 mins of cutting it stops cutting through. Then I have to drop the speed to 1.8% and the same happens again after just a short run. Even if I drop it to 1.5% after that it will cut through 15 minutes out of a 30 minutes job. Small jobs do not seem to be a problem at all. So it seems to me that for some reason the tube is not properly cooled. Can a hotter than required tube behave in such a way?
