Bambu Nozzle, bare wire?

Bambu Lab X Series Troubleshooting

Bambu nozzle, was clogged with TPU. i replaced nozzle assembly. today, i had the heat gun out, and TRIED to de-clog it. WOW, something was clogged, i heated it for about 5 minutes, kept putting in the nozzle cleaner wire, and trying to force filament form the top.
(also, #14 copper wire bare wire is a great ramrod)

FINALLY, something broke loose, and filament strarted streaming out, and i then put more filament in and it streamed out easily.

BUT, when i went to put the nozzle back in my storage box, i noticed the two wires, they look like BARE COPPER. I THOUGHT i melted the insulation on them, BUT other NEW nozzles i have also look the same.

ARE these bare copper, OR do they have very fine transparent insulation on them?

thanks

Those are bare wires. I would wrap each with a small piece of electrical tape (kapton tape, if you have it).

Brand new, never used, just out of the parts box:

Not shiny bright copper, coated in thin plastic or insulating varnish.

They have clear enamel insulation on them.

that’s what i was thinking, and seeing the NEW one with this, and yours also, i feel more comfortable. I thought i torched the other nozzle, want to keep it as a spare. but man, whatever was IN that nozzle was truly blocked, because once it cleared out, all other filament went through very easily
