Lost almost all power even at cold start.
Ameter shows 28mA but beam only scratches the surface.
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,

Hi, thank you for your reply,
The problem seem to be fixed now, not sure what mattered.
I have cleaned and reinstalled the tube (it was dusty)
I have changed the water in the cooler.
Realigned and cleaned the mirrors
Tought of installing a UPS
It runs ok now, the water temperature is not an issue anymore.
The neutral is ok-ish i think. Good to know though.
A thing I have discovered and it took me a while to figure it out:
When running at 10mm/s and lower The laser is running at the MinPower setting whatever the MaxPower is.
I was running it with 20% Min and 60% Max so it seemed to draw only 10mA (normal for 20%) at 60%.
Thank you again
