Finally someone who knows what he talks about. Thanks for the method, works way better than what I used to do.

[@porkyfedwell]

Unbelievable, it worked! My years-long enameled wire soldering headaches are finally over. Thank you!!

[@coolaj86]

You are welcome. I'm glad I could help. :)

[@mattportnoyTLV]

I usually use a lighter to burn off enamel. But I’m trying to work with 42ga right now. The flame burns the wire up. So I am very happy to see this method works.

[@electron7373]

Great mix of humor and really useful tech info! AJ rocks!

[@sacrajah]

Good demonstration for soldering of copper wire. I like it. Thank you for posting.

[@BenWillock]

This helped me a lot, I tried this method before but was using a lower temperature out of laziness. Perfect results every time!

[@coolaj86]

Yeah... Seriously... it's the simple things that get us, isn't it?

[@JuliusLemonhead]

Nice vid AJ, just what I needed 😁👍

[@joeanderson1769]

Great vid skills. And sound effects too

[@danielsaturnino5715]

Thumbs up for the special effects.

[@naderhumood1199]

V great approach.....deligintly good vedio. Thanks you very much indeed.

[@swiftsilver]

Thanks, i just wasnt using enough flux! You can never ever have too much flux

[@axk1]

Thanks! I don't have separate flux to cover the wire in, only flux core solder so I couldn't get it to work until I started adding solder right there as I was touching the iron to the wire. Otherwise the flux just evaporated instantly. Also when I brought the iron all the way up to 480 it eventually melted the wire )

[@Mars-un5gp]

Oh man you saved my day

[@maximusmark270]

Amazing

[@johgranger1304]

thank you

[@trevorlybbert3640]

You're a freaking lifesaver! Lol

[@jamesallen6007]

Many thanks to you. Just to let you know that over here, UK, it's very hard to get leaded solder and doing it this way doesn't work using unleaded solder, or rather I cannot get it to stick.

[@dephekt_]

Make sure you're using plenty of flux and that your iron tip is clean/not heavily oxidized. Oxidation is the usual cause of poor wetting, whether it's leaded or not. You may need to hold the solder ball for a longer period of time on the wire to boil off all the enamel. Stick your iron tip through your brass wire cleaner a couple times and reapply solder, then repeat the process of burning off the enamel again. If you see a ton of black/oxidation and smoke coming off it still then it's still burning up the enamel.

[@douglas2lee929]

I have the same ZOOM recorder. Awesome product.

[@kenshields1868]

I've seen methods for everythnig from burning it off with a lighter to using the bare tip to melt it off and it never works. This method however was perfect, thanks for putting it out there!

[@manwar999]

excellent...

[@kevinperies4450]

thanks alot

[@wd4005]

what about cleaning 0.1 mm wire? I am having a heck of a time getting the coating off.

[@nubrigol]

How come *my* soldering tip cleaner doesn't make that noise?

[@coolaj86]

nubrigol One of two things: Either it’s defective or you don’t have it mic’d well enough!

[@johny1220]

This was very helpful, thanks, I’m guessing this doesn’t need to be done for non enameled copper wire??

[@coolaj86]

Correct. If you just want to strip wire I'd recommend one of these: Yellow: amzn.to/2WOjqM7 Colored: amzn.to/38D2ihT

[@imkow]

the enameled wire of my earbuds pain me to connect. the enamel just don't come off...even after i burt the wire with a lighter..

is there a good way to do it in the middle of the wire too?

[@coolaj86]

Should work the same: Melt the enamel, Tin the wire.

[@szekerespista3758]

Can you recommend a chemical method too? Thanks

[@thebatu89]

Interesting, so you didn’t even have to strip the cable before tint

[@nucleo1772]

good job....where did you buy this 28AWG wire? any link?

[@coolaj86]

28 AWG Red Enameled / Magnet / Hook-up Wire amzn.to/2EYCPSj

[@naderhumood1199]

SIR. Do you recommend the wire for fixing pcb traces?. Many thanks....Appreciate your answers

[@coolaj86]

Sure. Just be careful not to rip them up further. The one I use in the video is pretty stick and thick and can easily rip traces. The thinner stuff is harder to work with.

[@jacksonmgani4411]

Thank uuuuuu

[@FormulaEverything]

liked it

[@deeareus9886]

thx for the tip, i got a microwave transformer and it was driving me crazy

[@tonycarpenter1226]

do i need to use 100w for 2mm thick copper coil or 60w is enough?

[@coolaj86]

That's hard to say because watts are a unit of heat dissipation, not a unit of temperature. Use a thick tip and try and see?

[@coolaj86]

If not, get a cheap-o super-hot iron, like this kzbin.info/www/bejne/l565eJ57qraWabc, or a really nice one like this: www.ebay.com/itm/275175931064

[@xandy6150]

Can I simply solder wires on the circuit after completing these steps?

[@coolaj86]

walker #36410 I’d suggest putting a small dab of flux on the copper or tin pad on the board and then applying a small amount of fresh solder. If there is already old solder on the pad (especially if it’s lead-free), you’ll want to put some flux on some solder wick (such as goot wick) and clean off the old solder before tinning.

[@xandy6150]

@@coolaj86 thanks a lot ur videos helps me so much.

[@davebl9645]

Tried and tried but just can not solder this stuff...l followed your directions to the T but l can not tin or solder to other wire....help please

[@coolaj86]

You may need to clean your soldering iron by tinning it and cleaning it a few times. You're probably not getting good heat transfer.

[@davebl9645]

@@coolaj86 thank you..what is the ideal temperature? I have a dishwasher pump motor with very find windings and a break at a connecting terminal has occurred that l am trying to repair.

[@coolaj86]

@@davebl9645 I believe around 400C, but this will vary based on the size of the tip and how well it's transferring the heat.

[@PaladinJenkis]

Wait a second, you've just used flux, that's it? FLUX?!?!?! These little suckers caused me endless headache when repairing cables.

[@coolaj86]

It's not the flux alone, it's primarily the right temperature - high enough to melt the enamel, low enough to not make the wire brittle (which is a nice wide margin, but starts higher than I realized).

[@PaladinJenkis]

@@coolaj86 Can't wait to try it, thanks a lot for this info! I've build myself a little station to help me melt the enamel from the wire. Basically a candle, a spoon and tons of tin. Never really worked.

[@pyunjunseo4197]

My solder simply wont stay on the tip of the iron. It just drops as soon as it melts. How do i fix this?

[@coolaj86]

It's probably oxidized or otherwise corroded and you either need to clean the tip or get a new tip. A good way to clean it is to get it as hot as it gets and then slide and twirl it across a damp sponge and then dip it in flux and repeat, and then tin it, wipe it, and tin it again. It could also be that your solder is old and corroded and needs to be replaced. Always clean and tin your tip before putting it away. And always put your solder in a sealed bag to prevent humidity from getting to it. If you want a cheap replacement iron, search my channel for "soldering kit".

[@pyunjunseo4197]

Thanks for the advice. I just decided to buy a better soldering iron as nothing worked on my cheap one.@@coolaj86

[@DaKILLaGod]

2:59 hahahahahha

[@mrschnider6521]

that only works with that brand of wire, that brand of wire glows in black light to make it easy to see where the enamles been taken off. what about normal magnet wire?

[@coolaj86]

Define "normal". Do you mean coated orange rather than coated red? Same procedure. Unless it's so fine that it burns away, in which case I don't know. But if it says that it'll burn away when soldered on the label, then it probably will - you just gotta heat 'er up a bit more first.

[@DangernoodleDave]

So far I’ve just been praying to the magnet stripping gods but maybe this’ll work better

[@coolaj86]

Instead of "Spectacles, Testicles, Watch, and Wallet" you'll need to do "Magnifier, Strippers, Flux, and Iron" - so that it's less of a cross and more of a zig-zag power / lightning symbol. That's what works best for me at least.

[@3niknicholson]

Excellent vid, sir, exactly what I needed to know, like-button-clicked...erm... are you guys actually allowed to use Celsius, isn't it un-American?

[@coolaj86]

Believe it or not, our official system of measure has been Metric since 1976. However, old habits die hard...

[@vu2dji]

This wire is marked with temperature 155c! Not all emamelled wire is not like this. Commonest one meant for winding motors and transformers is rated for much higher temperature, and enamel will not melt or strip at 400

[@doubleooh7337]

What temp does 4mm copper wire need to get to to solder? My iron doesn't do shit

[@siwd]

oh shoot i makde the like button say 666!

[@TheSushiman1787]

I don't know why but when I first saw the brand of the wire, it looked like b*tch go ... 🤪

Too much drama in this video

[@coolaj86]

Or... just the right amount!

[@TheAmanor123]

Nice video, how would you solder that bad boy with a microscope after?

[@coolaj86]

Don't be fooled by the tiny tips. I'd use the biggest tip that would fit to get the most heat transfer that I could, and then I'd use some wick (or even just the tip of the iron, perhaps a smaller tip) to remove any solder bridges. Also, search "smd practice kit" and give one of those a try with your setup before ruining something important. Once you get familiar with it you'll be surprised how practicing under a microscope enhances your fine motor control - even if your hands aren't particularly steady. You can be better than you'd think.

[@TheAmanor123]
