wire that heat strips insulation

[Ralph Mowery]

Where can I buy some small wire ( about # 28 to 30 ) that has the enamel
type of insulation that can be soldered and the heat will melt the
insulation ? There was some on ebay I bought that did not seem to work.
After checking it out, it seems that it needs to be heated to almost 400
deg C and when I tried that, it did not do all that well.

Wire such as Essex Soderon is solderable, as you want. The insulation melts
at approx. 237°C, well below 400°C.
Amazon, for one, has it at
https://www.amazon.com/Magnet-Enameled-Copper-Winding-Solderable/dp/B01EMHDXIM

there are 2 types of enamelled copper wire, some is solderable without stripping first.
Where? There are lots of electronic part suppliers. You didn't say what country.

Funny story...
25 years ago, I contracted some LCD monitors from Japan as part of
a product offering. They had been modded using that type of wire.
The QC manager took one look and insisted that they all be rejected.
YMMV

As far as those mod wires often used on circuit boards, the company I
worked for hired some engineers who worked in the aerospace industry.


We had them manufacture controls for industrial battery chargers and the
boards had to me modded by adding a few jumpers.


One customer did not like the looks of them though of course all was OK
electrically. Anyway, when I mentioned that to one of the engineers he
just laughed.
He said, "Battery chargers, heck we have planes out there flying with
green wires."

Soldering green wires is common.
The problem with the melting insulation is that you can't tell whether
you got a reliable connection among all the melted plastic.

The monitors in question used stranded wires with melted insulation.
You solder the joint, then snip the wire. The strands stuck out
in all directions, sometimes overlaying other parts or traces.
"Hoping for the best" was not attractive to the QC manager.

Google for 'solderable magnet wire'. Amazon has some, Adafruit has this:
https://www.adafruit.com/product/3522

I'm using 350°C iron and pushing the cut wire end to the solder blob
nicely removes 1-2mm of coating.( Don't breath the smoke.)

Hello. I had been looking for that stuff too, once. Unsuccessfully.
Do you maybe have some more trade names or brands I could use as search terms?
Soderon did not work on farnell..
and Essex gives only connectors n stuff.

Maybe the name of the coating would work. the hi temp crap is called polyurethane here I believe,
and strangely enough the farnell people have the notice solderable on all of that
magnet wire when it really isn't.

That yielded a result.
Funny. This is from their datasheet:

The wire requires a soldering iron temperature of 400°C+ to remove the enamel.
(Weller bit temperature code 8 or 9 or temperature-controlled iron)

How trustworthy do you think items are on Amazon?

I have had several negative experiences:

A 15" LCD monitor that I bought had a power supply that had no
registration marks on it at all. Taking a closer look was entertaining -
the power cord (also uncontaminated with UL/CSA/CE marks)) had a two
prong male plug going to a three prong computer style power female
socket. If you flexed the power cable at either end the insulation
covering the wires pulled out of the corresponding plug ends...

Another item of inferior quality quality was a LED night light that had
the metal threaded portion come up about 1/4" above the edge of the
socket - nice shock risk!

I would expect magnet wire sold on Amazon to possibly being poor quality
clones with insulation that probably doesn't meet its own "specifications".

If it isn't sold by a company with a physical address then I would
consider it too risky...name brand product means little, it is the
dependability of the company selling it that determines if the product
is counterfeit or not.

There is a lot of crap out there being sold to an unsuspecting public.

I am in the US.


There seems to be lots that will heat strip/solder around 400 deg C for
use on motors and transformers but I am looking for some that I can use
on circuit boards and will heat strip at a more normal electronic solder
temperature of around 300 deg C or less.

In use the wire will never get very hot, say like inside a computer or
TV.

Unless they make more than one type of wire labled like that, it takes
about 390 deg C to melt the insulation from a youtube vidio. That is
what I bought off ebay and it does es not melt and solder evenwith my
iron set to over 350 deg C. The same company does make some wire that
is advertised at a much higher temperature rating also. I bought 3
different sizw wire spools from them and none of them would melt the
insulation at anything near the normal soldering temperatute. I even
tried it at a much higher temperature with my hot air rework wand.

Years ago a company (think it was Hamtronics) had some kits that coils
were wound and the wire was soldered to the terminals without manually
stripping.

Before I dive into the magnet wire selection swamp, have you
considered using a chemical stripper or abrasive stripper?

For chemical stripper, I use common furniture stripper (methylene
chloride).
Dip, wait about 15 seconds, wipe clean, dip in flux, and tin in a
small solder pot:
<https://www.ebay.com/itm/NEW-110V-160W-50MM-Titanium-Alloy-Solder-Pot-Soldering-Desoldering-Bath/263799392388>
I don't have one of those. I use a stainless tubing endcap attached
to a big soldering iron with a hose clamp. Ugly, but effective. I
haven't measured the temp, but I'm sure it's less than 400C. Oh, they
make a commercial version of my kludge:
<https://www.ebay.com/itm/180W-280W-Electric-Solder-Pot-Melting-Tin-Furnace-with-Temperature-Control-HighQ/232835430586>
The down side of chemical stripping is that it's slow, but if you have
a bunch of wires to strip, you can just clump them together and dip
them in stripper simultaneously.

Drain cleaner allegedly works:
<https://www.youtube.com/watch?v=EbHFtX_KtbE>
but looks dangerous.

For abrasive magnet wire stripping, there are machines and tools
available.
<https://www.google.com/search?q=magnet+wire+stripper&tbm=isch>
The problem is that #28 or #30 might be too thin to do with some of
the tools. Try it with some sandpaper. If that works, you have a
chance. If you want to get fancy, grind a slot lengthwise down a pair
of tweezers or pliers that fits the wire diameter. Dump the wire end
in some abrasive powder, clamp, and pull. You will probably need to
do it a few times. I do this when I don't want to play with the
chemicals. Tin when done.

If OP is willing to have a solder pot running he can crank that up
to 400 and just dip the ends of the wires in the pot. That would
tin the ends and make them ready for soldering to the board.

Thanks for all the info Jeff.

I guess that wire like I really want is not around.

I am looking for an easy way to build circuits on a perf board. I
thougt it would be easy to just lay some magnet wire on a terminal and
let the solder melt the insulation. Then go to the next connection and
solder that one with out having to mechanically or chemically remove the
insulation. Does not look that type of wire is around.

So as I will have to find some method of stripping the wire, I might as
well continue like I have been doing and use the wire like the hard and
flopy drive cables. It is a small solid wire with the plastic type of
insulation. Easy to strip with just small wire strippers.

That's probably wire wrap wire. It's all #30AWG tin plated solid
wire.
<https://en.wikipedia.org/wiki/Wire_wrap>
The technology is mostly obsolete today. There were huge piles of the
pre-cut wire lengths and spools scattered all over the local surplus
stores. I have a few large bundles left that I use for making
breadboards. Highly recommended.
<https://www.ebay.com/sch/73139/i.html?_from=R40&_nkw=wire+wrap+wire>

The only things I use magnet wire for is torroid inductors and
repairing motors.

Look for WIRE WRAP wire, that meets your specs - the insulation melts
out of the way and is useful for low voltage work...
