I have a 150 W CO2 laser. I need to splice the high voltage power wire.

What type of wire is required and how is it to be spliced?

Pomona makes test lead wires rated at 10kV and more; this is what I used in the past for similar applications.

Here is how I spliced it:
- make a smooth solder joint with no sharp edges;
- smear some silicone sealant over the wires;
- put a heat shrink tube over it;
- another layer of silicone;
- another heat shrink tube.

You can shrink the tube right over uncured silicone. The excess will squeeze out.
