What should it look like ?

I just bought a 40w 2030 and hooked up the water supply, and there is a puddle in the bottom of the main outer tube.
I can see water flowing through the narowwer inner tube.
If I pinch the output water hose, there is dripping at the low voltage end .. inside the tube from the narrow tube to the outer larger tube

does that make sense ? :)

If so , does it sound wrong ?

It looks wrong, and the tube doesn't fire !

I've hooked the wires up to another tube and that fires ok

Help please :)

Thanks
Rich

Can you post a photo? There should be no drips inside the tube. Laser PSU's can be deadly so be careful if it is leaking water inside the tube.

yes I know about HV/EHT etc. Thanks :)... I'll maybe do a vid of the 'slosh' in the tube ! :) lol

How many water input/output ports are on the tube, there should be 4 in think. 1 input 1 output and 2 which need to be joined together to complete the circuit.

one in, one out, for me to connect ... then it goes out and in each end to cool the mirror and coupler

It's hard to see the water ... but you can see the outer tube just under half full ..

I think that water in the tube could be extremely dangerous, either from the electrical aspect or the risk of the water boiling and developing a high (explosive) pressure in the tube. Please do not power the machine up like this. G.

the 1st part was correct in this case ... the outlet water hose arced through the hose where is was near one of the tube mounting bolts .. so yes .. the water was at 25Kv !

All switched off and waiting for new tube now :)

And I'll have to fix the pin hole in the hose now too !
