what is this cable used for?:confused:Attachment 17466
It Prevents corrosion of the glass to metal seals in contact with the cooling water by acting as a sacrificial anode. Reconnect it immediately.Quote:

do you know which pin it should be hooked to?
can it be that it should be at ground potential?
Laserman532 worked at the factory, he'll chime in here in a minute. I cant remember, off the top of my head, because I have sold every 164/165/168 I've ever gotten my hands on.Quote:

iīve looked at some picturs on the net,
it looks like itīs connected to the anode!!?:confused:
sams laser faq says
Oh and yes, a sizable current is leaked through the tube assembly to the water, preferably from a designed-in ground wire that is installed at the cooling water input on the tube at the cathode end (thin red wire). Otherwise it comes from the anode block, which it will probably rapidly corrode.
so does this mean that i should connect it to the anode?:confused:
iīm starting to talk to my self through PL*retardo
The wire should be connected to the anode. There should be a thin red wire coming from the anode to somewhere near the cathode. As MG said, it's underneath the frame.Quote:

great thax
:D
is there any reason why someone has disconnected it?:confused:
seems stupid to do that.
the previous owner didnīt know what it was used for :eek:

It is not mission critical that it be hooked up laser will run fine without, you will get better PT life if you hook it up.
itīs alive :D
many thanx everybody

a new problem.
i get allot of "splatter"
or what itīs called?
on the wall around the beam
what should i do?:confused:
I thought we talked about this but. It is dirt on either the Output side of the output mirror or dirt on both sides of the beamsplitter in the OC holder.Quote:

Could a beam that is aligned off-axis, and therefore possibly grazing the edge of the bore, als cause this kind of scattering?Quote:

Be sure to follow Sam's Laser FAQ on optics cleaning though, as a 'quick wipe' could seriously damage the coating.
sure it could also be clipping the brewester stem...but the beamsplitter window looks very bright to me...not sure of power but it looks bright...just too much scatter.Quote:

but when i pass 34Amps it flips out with relays clicking and stuff??:confused:
is this normal over current protection?
why should i pull the current and field to max when turning off??:confused:
/martin
btw
itīs at 32Amps 1w in the pictures
it should go higher but it doesnīt want to
so maybe i should align the tube and clean the optics :)
do you guys think the fill is ok?

32 amps field max you should read 237 to 243 volts across the tube. 1 watt sounds good, clean your mirrors and brewesters
no your power supply is set to 32...i can tell you how to turn it to 38...but 35 is what I would reccomend
