Hello,
I have recently purchased a chinese Laser CNC with a "150W" RECI tube. (150W in chinese means 130W nominal power with 149 peak power)
All was ok until a few days ago when I noticed a sudden loss in the current drawn by the tube.
If until know I was running the machine at 60% (at 28mA) now I have only 14mA or so at the same 60% and the cutting is poor.
The water temp is 18degC at first then it goes up to 20degC.
If I let the machine off for a few hours and then start it again I have the power restored but only to lose it after 5-10 min.
Any help will be much appreciated.
Thank you,
