Hi Guys
So today just after starting the laser decided not to fire, at first we thought the PSU had gone but on closer inspection we found the High voltage (red) lead going to the tube has a soldered joint just before the tube it is covered with tape and in turn is covered by a piece of silocon tube and ten taped at both ends
It had arced right through the tape and tube, once re taped and put back into the rubber tube the laser fires again the question is what would cause this to happen in the first place
any suggestion on this
thanks
Dave
