Removing laquor
« on: June 09, 2017, 09:27:17 pm »
Hello
Can anyone tell me how to remove the lacquer from the copper wire as on transformers please.
I have tried iso and scalping it with a craft knife but can't get a good contact.
Thank you gurnsdale

From experience the best way is scraping - sorrry!!
Use a scalpel or a craft knife. Scrape along the wire - rotate the wire slightly an scrape again until you've scraped all round the wire. The wire should look bright all the way round - keep scraping until it is.

Size matters - especially if you don't have a lot of space - and N gauge is the answer!

Emery cloth is good. If you try and burn the enamel off you will still have to scrape the residue.

Burn it off then scrape with your fingernail.

Yeah, a wee bit of fine sanding or needle filing. You can see the copper shining.

Then I tin it with solder, and then I know there's electrical continuity.

Depends on the type of lacquer:  some types can be burnt away by the act of tinning the wire, but as others have said the best way is scraping/sanding it off.
