Hydrochloric acid is very harsh so the zinc will tame it down a little. This is a very good stuff for soldering but it tends to eat up also the plating on the soldering iron tip. I damaged a lot of tips before I realized what was happening. I myself tried a lot of different stuff and I also found that some rust removers that contain phosphoric acid also work very well even to solder stainless steel.

[@ashchbkv6965]

Do rust removers also damage the soldering tip?

[@supersilve]

@@ashchbkv6965 yes they do as the acid in them also attacks the plating. Unfortunately all fluxes tend to. It all depends how harsh the flux is. Knowing that the plating is very thin on the soldering tip we have to take care what to use. It is best to clean the surfaces with some steel wool or fine sandpaper before soldering. The flux also makes some kind of cover not to let the surface oxidize as with heat surfaces although cleaned tend to oxidize faster when heated. I tried soldering on aluminum as well this time I used cooking oil and keeping the solder under the oil not to let oxygen touch the material. I succeeded in this as well.

[@ibringthelastwords1358]

Thanks for the tips! The most applicable task for this is soldering batteries because its fast reaction which doesn't heating much the batteries and not damaging them. We should just use cheap ass soldering iron 👍

[@pafunleal3849]

Excellent. Fosforic acid has even a better effect than HCl with dissolved Zinc added to less corrosion in the tip and circuit parts. Dentists use Phosforic acid in their jobs. It is very cheap and small amounts are necessary to aid soldering steel or stainless steel with regular electronic solder

[@GeoffTV2]

I had no idea that a flux could be good enough to do that. A big no-no with soldering is to melt the solder onto the iron and then try and paint that onto the workpiece. It never takes properly and the result is a poor joint. Yet here you are just dabbing the solder into the fluxed area and getting an instant joint! amazing! It made me smile that you poured hydrochloric acid into an unstable broken container. Holy cow! I think you need to be a bit more careful than that :-) That's the sort of thing I would do!

[@paulcohen1555]

That's exactly what I wanted to write! Don't forget to clean the items after soldering with that stuff!

It would be worth annotating that the batteries must be carbon-zinc type, as they are almost unseen in Western countries. Here we use almost solely alkaline and lithium batteries.

[@scottpelka1211]

New American penny's made after 1983 are 99 percent zinc if you are looking for zinc instead of tearing apart a battery for it.

[@muhammedfatihsaruhan7532]

hey thanks for the video . i see that u used some type of other metal that you cut other then battery scrap. what metal was that ?

[@sam500600]

It was zinc from the battery internal cover

[@hummmhowto2493]

It is zinc metal

[@WaschyNumber1]

Hi, how high is the Acid Percentage that is in the bottle? 🤔 How high need the Percentage % be if the Acid to work? 🤔

[@hummmhowto2493]

The concentration ratio does not matter, the more concentrated the acid, the more zinc it needs

[@bhawnasagar130]

Want to solder 1./mm stainless steel wire is it possible ??

[@diygeneration5566]

*Very interesting way to make flux. What kind of batteries do you use, saline or alkaline? Do you dissolve the zinc? And I have another recipe for the simplest acid-free liquid flux. Come and visit, you'll be interested;-)*

[@randomblogger2835]

They have the zinc on the outside so they are saline batteries.

[@souravbhattacharyya3392]

Great work,just tell me onething...after the chemical reaction of Zn and HCl is over,then also do we need to wear gloves to touch the material so formed?

[@hummmhowto2493]

If the zinc percentage is sufficient, the acid will be diluted to a degree that does not harm the skin

[@randomblogger2835]

wash hands after use is sufficient, use vemtilation, wear eye protection.

[@Lyondegreat]

Can we use porcelain cleaner for this since it contains some HCL acid in it? Finding HCL locally is difficult here

[@benalfano4533]

So use the sulfuric acid from an automotive battery instead of HCL my friend 😊

[@codyramos3200]

Muratic acid is essential the same as hydrochloric acid. .. . should be able to find at any hardware store .

[@csthakkar9246]

Citric acid,is good soldering flux,

[@sumarianson]

Hydrocloric acid is highly corrosive. Even when bottled its fumes can destroy nearby metals with corrosion. I know from experience. Would this corrode battery terminals if they were soldered with this?

[@5naxalotl]

zinc chloride us almost universally considered unsuitable for electronics soldering. it's a good flux for morons like me who can't solder because it's really effective, but i've always been careful to wash the part clean and also i'm not doing serious work. it's a traditional flux for things like plumbing, but if you're struggling with electronics joints then basically you're supposed to learn how to solder better, because it tends to be corrosive even if you didn't leave excess acid in it. in general, you should be very suspicious of the long term corrosive power of stray chloride ions. fwiw, you can buy ZnCl very cheaply in a nice secure bottle in hardware stores

thanks a lot my brother but what will happen if the zinc is more or less , is there a special thing can tell me if the zinc is enough or not .

[@hummmhowto2493]

The reaction of zinc with the acid dilutes the acid to become usable

[@SamerM.ElMeligy]

@@hummmhowto2493 thanks again and again i made it and it is very good solution for many kinds of soldering . wish to you all the best my brother

[@thiamjoo]

The best way is to add more zinc. If there are left over unreacted zinc that means all the acid is used up to dissolve the zinc so the solution should be quite safe. If I still remember my chemistry, the solution is Zinc Chloride.

The concentration ratio does not matter, the more concentrated the acid, the more zinc it needs. The best way is to add more zinc. Until the reaction process is over.

Zinc only reacts with the acid to dilute it

This is the same as acid core solder. Do not use for electrical work as it will eat the base metal. Use rosin core solder.

[@medaturbo9899]

Hi. Attention: Hydrochloric acid (HCl) is a toxic substance besides the convenience it provides. and causes great damage to most surfaces, especially human tissues. For this reason, safety precautions should be kept at the highest level while working with this acid. Hydrochloric Acid, besides being toxic, is irritating to eyes and skin, causing skin burns. and is irritating to the respiratory system. Those who want to do my work in the video should definitely use gloves. And this process should be done in the open air, the gas should not be inhaled...! Thank you

Hello everyone! I have 2 questions: 1. What is the effect of the chopped zinc in the battery? Is it really important for this? 2. What concentration does the hydrochloric acid have? What percentage is it? There are different percentages in the pharmacies! I would like to thank you very much and hope for an answer. And hopefully “Google” translated everything understandably. Best regards and good luck!!! And. May the force be with you!
