I have been reading some threads about people having difficulties trying to connect the high tension leads to the glass laser tubes.
I wrote about this in another thread but it was buried so I thought I would start another thread to make searching easier for those that need to know.
I have never liked the idea of wrapping wire around the terminals and then trying to solder them as it's still not a good enough connection for my liking so the easiest way around it is to use an electrical wire joiner of the household type. The EARTH joiner/connector has 2 screws but the neutral and active ones only have 1 screw. The picture below shows what I mean.
OR cut the end off a terminal strip and use that as it has a hole both ends and is also insulated
If you use the wire connector then get the EARTH type as it has 2 screws in it. 1 screw for the laser tube pin and 1 screw for the wire.
You don't have to tighten the screws very much but just enough to make a good connection that won't vibrate off
I don't know why the manufacturers tell people to solder the connections as it is way too long a process and too time consuming and also you could crack the tube if you heat it up too much.
Here is a picture of the 2 different types of connector that you can use.
