Hello see you soon with a new project
ATTENTION: Informative video not to be replicated, all the actions of this video have been performed safely. So I do not take any responsibility in case of accidents in the replication of this object. - บันเทิง
Thank you. It was a quick job assembling a spot welding device. Crude but serves the purpose. Well done.👍
It would be nice to add a timer to make the spot welder impulse.
this is a ghetto contraption not a welding device
Couple of safety issues & suggestions here:
1. Please, for the love of God, if your gonna run the hot & ground wire through the case, use a grommet so the wires don't chafe and short out.
2. Suggestion for version 2: see if you can wire in/DIY a foot switch. Maybe salvage one from an old sewing machine?
3. Suggestion for version 2: mount a heavy duty alligator clip on your negative probe, and mount the positive probe on an overhead handle so all you have to do is touch it for the spot weld. The alligator clip will help you get a better grip to hold the nickle strip to the battery, as well as supply the ground for the spot welder.
Ok thanks👍 👋👋
Здесь нет отрицательного и положительное зажима
@vinnyboombatz1399 you have to move the - close the the + each time you do a spot weld it's not the same as arc or mig welding but I'll admit I thought the same thing as you at first. And I agree the way the wires are run through the casing is just asking for a short circuit lol I would def use a grommet or rubber hose to insulate better
Bravo! Simple and effective!
Thanks👋👍
I enjoyed this video and your non-verbal communication was great. ~Thanks
I would advise a few things for safeties sake here. A thick metal bucket half filled with sand, and some extra cable protection as it exits the case to protect the insulation from getting damaged and shorting things out.
Expect some of the Lithium Ion cells to not like this welder and start gassing and worse, when they do use the bucket and get them outside fast. Just search here for lithium battery fire and explosions. Really people be safe, this is not for the faint of heart.
Ok thanks 👍👋

@@GianniPirolaFaidate i ve made the same project as you but i have many sparks during welding and it does not weld properly.Also i used wood to make the case for the transformer and i removed the ground cable from the input,could be this the reason?
@@thetoymaker9404 sounds like voltage too high and/or current too low
without adjusting the current - it really threatens to explode the battery.
I would strongly recomend matching the cells before re-installing. Run a few charge/discharge cycles. Odds are really good that your #1going to have a fire or #2 your going to have the battery back open because the 2 older cells cant keep up with the new ones. If its only 5 cells replace them all.. But replace them with cells that you know there capacitys. Matching cell capacities is critical. If you dont have a hobby charger (imax b6, sky rc, thunder, prophet, etc) then i eould say dont take on the lithiumbattery repair/swap. Often times the control board is whats bad anyways.
the charger part has a bms installed...fire? I've tried to get one, uptil now have not succeded. maybe it's me
You don't need to match capacities, that's the point of a battery balancing system.
@@ixamraxi your mistaken. The bms wont operate as advertised if you dont pre match the cells. Please allow me to save you some time and effort. Match your cells and always check each cells internal resistance. If you do those 2 things your battery packs will last a long long time. Years and years. Especially important if your using recovered cells from laptops etc.. You can buy a hobby charger like a sky rc imax b6 for less then $50. It will charge and discharge. It will balance charge up to 6 lith-ion cells. And it will check your internal resistance. If your getting a ebike and you tinker absolutely get one. I have 4 of them so i can analyze cells i recover faster.
@@kennedy6971 It will, modern bms systems will simply limit all cell performance/capacity to the lowest one, which improves longevity of the pack as the cells slowly degrade over time. You could get slightly better performance by pre-balancing, but generally individual cells are close enough in manufacturing quality that once charged you can check internal resistance and grab a set that all show the same voltage and be confident their capacities are close enough to the advertised value that the bms will sufficiently protect them for the expected lifespan. I would seriously doubt any claim that major manufacturers are balancing more than this.
@@ixamraxi The only problem that I see with what you've written is that it only applies if you already know FOR SURE what the specs of your batteries are but we arent talking about that kind of scenario. In this video the batteries used to replace the bad batteries are probably not from the same manufacturer as the original batteries. The fella in the video doesnt say where the replacement batteries come from or how old or used they are. Neither does he show that he tested ANY of the batteries for ANYTHING. All of this matters more than you might think. Lets say that the batteries in the drill pack are LG's, rated for 1500mah's so you grab several random replacement batteries based upon the fact that those replacement batteries are also rated to have a capacity of 1500mah. What if the LG's remaining in the pack are NOT 1500mah anymore? And are you sure that those random replacement batteries are still 1500mah as well?-or ever were? AND are you sure that the replacement batteries are rated for the max continuous current draw that battery operated power tools like a circular saw demand? And are you sure that even if the replacement batteries have a high enough max continuous current draw rating to properly run a battery operated tool, does that rating match up with the max continuous current draw rating of the LG batteries that remain in the battery pack? 18650s put into power tool battery packs have a max continuous current draw rating of around 30amps and up. Your run of the mill 18650 removed from a laptop pack usually has a max continuous current rating of less than 2amps!! Now, imagine trying to pull 30+ continuous amps from a lithium battery designed to tolerate less than a 2amp continuous output. Can you say FIRE!? There is a whole lot more to "matching up batteries" than simply getting the capacity ratings listed on their outer covers as close as possible. Speaking of which, lets go back to that part of the topic. I recently pulled a bunch of LG 1500mah batteries from two 5 year old, aftermarket 18v Ryobi battery packs that werent charging anymore. One 18650 "cell" in each pack had gone bad. The rest of the batteries from each pack were good BUT all tested out at just 75% to 85% their originally rated capacity. Its normal for lithium batteries to lose capacity over time and use, so unless you test them, you have absolutely no idea if a used lithium battery still has its original capacity or not. So yeah. Im with all the folk in here who recommend making sure that you know the "TRUE" stats of your batteries by testing each before using any of them in a project such as the one shown in this video. As I said, there is MUCH more to these 18650 batteries than simply throwing a bunch with similar capacities together in a pack.
Thank you, very educational! I learned some new things. You are a good craftsman.
Thanks👍 👋
Mamma mia!! Ogni volta porti un progetto fantastico e stavolta addirittura due!! Veramente ingegnoso e a costo zero! Incredibile...
Grazie amico mio 💪👍
Nice project , thank you for sharing, the wires of the secondary should be thicker though to handle more current.
thnaks !!!! bye
@@GianniPirolaFaidate ذذطط
I love the idea to use old PC power as box since it already have the connector and on/off switch! 👍 I think I will do the same as you for my next one. This said, my suggestion, don't spot weld with charged battery since it's then they can start a fire. Discharge them to like 20% (Like 3.2 volts), then you can more securely spot weld them since now not a lot energy to start a fire. Another thing, look like your weld is too hot ? Maybe try to lower your current or use a timer to cut power before it's too hot?
Thank you very Much.
ok many thanks bye
nope, tried that

They try to make up for lack of skill. Pros have to make do
The most skilled professionals can repair what they have or create their own tools from scratch, improvise unusual solutions when necessary, and rely on their skills to use whatever they have available to get the job done.
Unskilled tradesmen rely on the tool to do the job for them and are often helpless without their specific equipment, whereas skilled ones rely mostly on their understanding of the work and what needs to be done to accomplish their work, so the tools themselves become much less relevant. Ideally, you'd have skilled tradesmen who also have excellent tools to work with, but the skill is always more important than the bear.

I would strongly recomend thicker wire for the replaced coil. That wire used in the video can get hot and melt the insulation, when in use.
You are definitely right

Уважаемый! Вы молодец!
Для ремонта на необитаемом острове, при наличии кучи металлов и старых запчастей, по технологии - "И так сойдёт!" - Просто замечательно! Супер!
Ну а если подойти к решению вопроса ремонта батарей, то куча нарушений при замене акб. Это и выбор новых элементов вместе со старыми и перегрев элементов при сварке (100% будет больше сопротивления в миллиомах), ну и не аккуратность.
Он же не русский😂😂😂
Этому уважаемому язык подпалили по-видимому. И нахрена такие ролики ваще выкладывать здесь
ему бы ещё фенибута пропить курс, чтоб тремора не было, а то руки ходуном как в запое, не удивлюсь если он за кадром ещё и пляшет произвольно
а так напрожигал дыр в ленте, такой себе ремонт
После одной точки элемент уже горячий , нельзя нагревать до красной точки , а здесь уже негодный для работы элемент .
Порожает,сваривать ячейки нержавейкой(всеобщая практика) Бьётесь за низкое сопротивление каждой ячейки,потом засовываете в жопу это,таким соединением,плюс перегрев сваркой или пайкой.Кроме постоянно оттапыренного вверх большого пальца, у большой категории токих умельцев, наблюдаю только метод,,абы как".🫢
Good and fast to make converter!
Tnx Gianni!
Thanks 👍👋
Your video is really good, informative. How do you get this transformer is it a damaged one or good one?
Buen trabajo, pero yo sugiero cambiar todo el kit de baterías , así la carga será pareja ,las usadas no sabemos que tiempo de vida les queda., gracias
OK, gracias, adiós
Так чаще прожигает,как сваркой,я поставил микрик,на вкл.220в на одном электроде,держак сделал из кусочка фанеры плоским,типа рейки,а жала из провода заземления 3мм,прижимаю-нажимаю и отпускаю микрик...и ВСЁ...контакт не дрожит,искра не скачет и получается чистейшая КОНТАКТНАЯ сварка.
Все равно не понимаю что куда подключает. Трансформатор от чего он взял и к чему припаял? Ни схемы ни копонентов не привел.
@@user-hz1ew1jr9d Советую и не стараться понимать. Особенно момент приваривания. Следующий по глупости будет приваривать газовым резаком
@@user-hz1ew1jr9d Трансформатор от микроволновки. Вторичка удалена. Вместо нее несколько(2-4) витков медного провода. При сварке важен ток, а не напряжение, поэтому важна толщина провода, а не число витков. На видео провод тонковат. Собран самый примитивный вариант, поэтому много искр, что не есть гуд. Повторять не рекомендую. Это хрень.
@@alsm61 спасибо!
Я просто ударяю по микрику пальцем , чтоб не перегреть точку . Буду переделывать держак по типу китайских - микрик на один из электродов поставлю , а ставить релюшку пока нет желания возиться .
Another job well done 👏, bravo Gianni

This looks really dangerous! 💥It will only be $0 if you have all the parts already, but if you don't have a broken microwave and everything else you need, it will be more than $0.
BTW, you should not have metal rings when working with cells and welding.
every week i see them at recycle points together with old 18650 equipped laptops or on the kerbs
Or watches.... I watched a metal bracelet light up on my uncle's arm, just working with 12v. It looked painful, between the laughing. 😂

Great job!!! What was the transformer taken from?
Also, where can you get thin metal strips like you used?
I"ve been thinking of doing something like that but in a much cruder device, like using a storage battery with 12 foot jumper cables and home-made electrodes like yours. It made a much neater (and probably safer) spot welder than what I was going to use.
@@petemiddleton64 Thanks!!!
Microwave transformer
@@bonaufilho7703 Thanks. I thought it might be from a microwave.
the strips are actually almost (!) the same as the exterior metal part outside of a battery
I’ve just run across your channel and I am very impressed. I hope I don’t sound like a jerk but I’ve watched two of your videos and I want to build some accessories for my press and a spot welder to repair some (expensive to replace) battery packs. Thank you for sharing!
Thank you very much, I'm glad you like the videos. HI 👍👋
A very fine and useful one, with some pink panther flavor!
Можно было просто припаять используя флюс для пайки стали или таблетку аспирина, если нет флюса.
Делать сварочный аппарат имеет смысл только если вы ежедневно проводите такие же ремонты.
И пускатель поставить с ножной кнопкой, прижал нормально контакты и включил толчками.
Хорошо, спасибо, пока
Греть нельзя, можно потерять какойто % от ёмкости!
@@almotik8514 пусть паяет, он ещё не видел и не ощущал как они хлопают 🤣🤣🤣
и не просто хлопают, а с огоньком 🤣
когда увидит - бум от кондёра для него будет комариком
При такой сварке элемент уже можно выбросить , чудо что он не прожёг элемент . Хорошая сварка происходит за счёт кратковременного импульса тока большой силы . Тогда и элемент не нагревается выше 60 градусов , и пластину оторвать невозможно .
That should read. Add a Rheostat to have voltage control and I would also sleeve the leads through those sharp metal holes. Great job though. The other thing is to use thicker gage weld leads and add another turn to quieten the hum
There's more to using a rheostat than you've implied. How will another secondary turn reduce hum, exactly?
Perfeito!Mas poderia colocar um control de tempo, em que você regula o tempo de desligamento do ponto de welding!
Thanks👍👋
Add capacitor for power factor correction it will work alot better
Thanks👍👍
Прежде чем выкидывать отдельные батареи надо было попробовать их зарядить не выкорчевывая их с места зарядником для сотового телефона. Некоторые поддаются зарядке до полной ёмкости. Может быть не пришлось бы их разбирать.

@@koss7210 Посмотрите промерку напряжения до демонтажа банок. 3 шт по 0В, одна 2 и одна 7 (как может быть 7?). О чем это говорит? Какая балансировка. Хоть бы полосу под обрезанные пластины засунул - ан нет, поверху и пожечь сильнее,что бы термоусадка двух соседних АКБ подплавилась. Проще было бы подпаять.
@@user-nu1ev7ci8z посмотрел, там не 7 а 0,07в.
Вот на каждой 0 - 0,07 - 0,02 - 0 - 0,02в - это что за напряжение на банках? Какой балансир, тут батарею З/у не видит и не запускает. Нужно вручную каждую банку зарядить и на остаточную емкость проверить, хотя литий если разряд ниже 2-2,5 вольт - то там такая потеря емкости и деградация, что в мусор сразу ото всё...
А этот мастер итальяно, что-то там намерил, оторвал, припаял. И Хорошо, Спасибо, Пока!)

@@koss7210 Я тоже удивился, что сразу три и в нуле. Ну в крайнем случае 2 и то какое то напряжение должно быть. АКБ все однозначно в мусорку. Мне кажется с платой БМС не все в порядке.
@@user-nu1ev7ci8z дело не в Бмс. Сам аккумулятор со свалки, давно валялся, год может и больше, поэтому все банки в "ноль" - такое в мусор. Он поэтому может так небрежно паял, зная что потом просто выкинет его

I would think you would have to isolate each battery to get an accurate reading on them with your ohm meter .

Bellissimo progetto , geniale aver usato l involucro di un alimentatore da pc per contenere il tutto , dirò una cosa ovvia già detta , se aggiungi un pedale ed un timer monostabile al primario , fatto ad esempio con un ne555 ed un triac , si potrebbe avere forse più precisione e ripetibilità nelle saldature , bellissima realizzazione come sempre, complimenti.

Да, именно так, иначе можно перегреть литиевые аккумуляторы и они взорвутся !
great DIY. after wiring , to check voltage on the output how much Volt do we have to see?
Thank you. I don't know how many volts it is mm I'm focused on the amperage. keeping it low so it doesn't burn. bye thank you
Одного не понял: накуя было отрезать старые перемычки с дырочками от оторванной сварки и приваривать новые???Чтоб видео снять?
Старые кривые косые, плоскости примыкания нет, ток будет плохо протекать. Я бы тоже новые приварил 0.2 толщиной.
Я тоже не понял. Но это загадка мастера..
@@alenikverЯ старые выравниваю молотком и затем припаиваю. Все получается отлично и никакого риска прогара.
Легче приварить новые , чем старые оставлять , при плохом примыкании или не будет нормального контакта , или можно даже элемент прожечь .
Really interesting. I’m very impressed 👍
Thanks 👍👋
Are you feeding the m/w transformer directly with AC or the only part you are using from the computer power supply is the rectifier?! Sorry couldn't follow the video what connections you did. Thanks!
Non ti smenisci mai, bravissimo. Se avessi usato un filo di rame più grosso peril trasformatore, però, sarebbe stato meglio.

Желателен таймер для подачи коротких импульсов. Вторичная обмотка тонкая, 10-ка, нужно 35мм как минимум. Ужас.
Так у него и лента никелевая тоже максимум 1.2 мм . И то греет её до красна , а это хана элементам

Ай да Идея полный бред.
Хе за то чтобы попасть к доктору ДЮ 🤣🤣🤣😂😂😂
Spot welder should allow the current for a small fraction of the time when it's pressed, when you're replacing cells in the battery you should do all cells not only 0v's. And those welds are really terrible. It's 0$ fire hazard and I would go buy normal replacement if I had to do this.

Nice. You exceeded my expectations.
Thanks👍 👋
Never "add" new cells to an existing pack. Always throw each and every one out (or re-purpose them as single cells), and replace the entire packet. These cells that haven't yet died, are going to die sooner or later, and then, you'll have to open it up again and again, creating an endless cycle of "adding new cells to half-used ones"
Also, the "bare transformer" method is a surefire (kek) way to have yourself a lithium fire on your workbench :v
These 18650 casings are thinner than they look. Yes, it might be cheap, but it is just not worth it in the end. The lowest effort "spot welder" would be to have an SCR controlled with an Arduino, and then to set the pulse duration via the code (or implement an encoder / buttons & a screen to see the set value, if you have a bit more money to spend), and then have the Arduino turn on the SCR for a set amount of time. Then, have some trash cells at hand (best to discharge them completely via a resistor, something like 100kOhm or more will suffice, just tape one lead to positive, the other one to the negative terminal, and leave until the voltage drops to 0V). Then, try your spot welds on these, because when a cell is completely discharged, a potential failure won't be as dangerous as it would be with a cell that has the nominal 3,7V (but they still can be dangerous, so a metal bucket with sand is very, very much advised).
Bravo. Too good.
This is a really useful video.Thanks for Sharing👍
Thanks👍👋
Der Strom ist für die Punkte zu groß. Ein paar weniger Windungen im Trafo wären besser, weil das Material nicht so schnell verbrennt.
Thanks👍 👋
Furou muito a fita de niquel mas eu te aconselho usar um rele de partida de moto facilita muito na solta e só liga o transformador na hora que vc acionar o botão do rele apenas um toque
Thanks👍👋
Sono le quattro di mattina ed ho appena terminato di lavorare in laboratorio. Ma prima di andare a dormire mi sono concesso 15 minuti di lezione a scuola di Gianni. Grazie
Grazie mitico 💪💪👍👍👋👋
Dont be alarmed when you start poping breakers especially with no pfc
Thanks👍 👋
