There should be writing on the side of the insulation that says what gauge it is.
It's 1 square mm. So like 20 AWG, a little less. Somewhere between 20 and 22AWG.JMPGuitars wrote: ↑Sat 03/28/20 6:25 amThere should be writing on the side of the insulation that says what gauge it is.
There's no hard-to-read writing on the insulation? 1mm is probably 18AWG. 0.8mm is more likely 20AWG. But this method isn't as reliable as reading the print on the insulation.
I think you're wrong about this one. In Europe we express wire values in sections, meaning the surface of the wire diameter. In the USA the wire is expressed in diameter. Or do you guys mean 20AWG is the surface in square something?JMPGuitars wrote: ↑Sat 03/28/20 7:23 amThere's no hard-to-read writing on the insulation? 1mm is probably 18AWG. 0.8mm is more likely 20AWG.

I could be, but I dunno. I googled it and those were the numbers reported. I just measured a 20AWG pre-bonded wire and my digital caliper says 0.9mm, which seems consistent with non-bonded 20AWG wire being 0.8mm.

Nothing to do with the voltage. You tested without the tubes, and voltage was insufficient anyway. The gauge part of this conversation is only about making it easier to wire the heaters. As long as the wire you use is rated for the voltage and current going through it, you're good.
