Post by a77an »

Hi i bought this power source hire a few years ago: 40W~60W PWM CO2 Laser Power Supply (AC 220V)

It is possible the water protection switch is bad. if that switch is bad then the laser power supply(LSPU) will not activate.
if you have a digital multi meter (DMM) check for continuity by putting a prob on each side then turn on the water chiller. if it beeps then the switch is good. or it can be a bad switch on your cover that can prevent the machine to work.
