http://cgi.ebay.co.uk/Brand-New-40W...hash=item260266252426&_trksid=p3286.m14.l1318
I bought mine form the same seller, but for 80 GBP and 60 GBP shipping. not bad!!
I got it today, good condition, very shmexy, but one problem...
no manual... and the seller had NO IDEA what I was talking about
(
me: "I need to know how many kV and mA input this needs, AC or DC"
Them: "220v in, sorry, not know mA of"
)
so... I did a LOT of research, and spent some time on SAM's laser FAQ... and so I gather a small co2 laser can be powered by a neon sight transformer. I happen to have a bunch of those, around 15kV and 16~20mA.
BUT, then I came across this:
http://www.powerlabs.org/laser.htm
He had his hooked up to "a 15kV 20mA solid state neon sign transformer fed through a full wave voltage doubler"
... more research ...
So I gather he was running HIS 40watt CO2 laser at 30kV???
but then he says: "The transformer failed after 4 minutes run time, but it did work for the initial tests.
The current power supply consists of a 12kV 60mA 60Hz Neon Sign transformer fed through a full wave bridge rectifier. This feeds 720watts into the tube, which is excessive and will
shorten tube life, but does provide for some very impressive performance."
so that means he is running it off of DC???? but 12kV??? I am confused... Experience has told me that with lasers, be worried about the current, or in other words screw the voltage... but I DO NOT want to screw over a $300 laser tube.
also, My tube (as you may be able to see from the pictures) has some plastic/siliconlike/whatever tubing connecting two tubes together, and there are two open tubes which I am guessing is where the water attaches. can someone guide me as to what is going on?
help needed, thanks
