I’ve recently bought a K40 laser and tested it today. Sadly when I tried to test the laser there is just some crackling noise and arcs from the red wire “small white box” from the picture.
I don’t see any water leaking into the tube so I assume the tube isn’t broken or anything.
I’m kind of out of ideas what it could be or what could solve it.
The ground wire is connected to the frame, the mA meter always stays on 0.
I also thought about isolating the white box and the rest with some silicone that came with the laser or the tube could be in some other way defect.
Does anyone have any solution?
By the way, I drew where the arc went out because I don’t want to run the PSU and damage it in the process.
