AS some of you might know, I have a Shenhui that originally came with a 150w RECI. That original tube was arcing to the frame much too easily, and it was recommended by Shenhui, Reci, and many here that get a warranty replacement. So, I did.....problem is that that replacement arrived broken....and the 2nd replacement arrived even more broken (but packed better, go figure).
Leading me back to replacement #1. On that tube, the break is right where the little coil is, as shown.
So my question is....what does that coil actually do? It isn't cooling related, and it seems to be a link from the outer gas reservoir to the inner laser tube. I know this for sure as I have the first tube with the ends broken off as RECI asked me too, so I could feel where the tubes met up. I have two possible theories. One is that the length of the glass coil insures that the arc of the laser voltage only wants to stay in the center tube. The second is that it is for preventing condensation from entering into the active laser section.
I am tempted to mount this tube and see what happens. Obviously, if the purpose of the tube is the first theory that would be a *bad* idea. If it's just condensation, should work fine (at least in short bursts). Any ideas?
(I just measured / guessed the length of the coil if it was extended, and it's a little longer than the lasering tube....hmm, time to see if anyone else knows the actual answer)
