#SpotWeldingPowerfulHomemade
__________Thanks for watching________
Rj Edit All
I built something similar. Copper doesnt work for the electrodes. They just get welded to the nickel. I used tungsten from a tig welder and found success.
❤️
Полное дерьмо, прожиг акумуляторов обеспечен.
You can try, 100% save, no damage problems
After making this spot welder I would recomend not bother with this. Put a bit more money and order a kweld or something like that.
6:47 Totally horrible, without power and/or time control the result is this, overheating of the solder and consequently the cell poles, is posible damage cell in this consition and too cause explosion, very bad !!!
Well, if you circuit diagram is correct this is unfortunately not a very good device, it simply will not last long. For several reasons:
1. Your 80A relay is badly underrated for the currents involved (circa 200a).
2. Your tiny push button is extremely underrated. It's max rating cannot exceed 0.5 A, the current you are pushing through is
3.7x3/0.22=50.5A!!!! That button is a goner.
3. Your capacitor is in parallel to the power buttery irrespective of the state of the relay, I can't see it's purpose. Also an inductive pulse
created in the power wires during welding can easily exceed it's rating of 50V, it can also damage the battery. So protection is
required, eg a TVS diode.
4. Duration of the welding pulse depends on nimbleness of your fingers, not a very good idea.
Of course, if the diagram is not correct the comments above don't apply.
@blg53 do you have a channel with better spot welder project ? I want to build one
@@astasidhy4243 I have built one, but I did not record a video about it. What I suggest you do is to search RUclips with " diy spot welding machine". You will get a lot of hits, but be very selective about which one to imitate, pay attention to my points in the previous post. Some designs involve a car battery, some other batteries, some microwave transformer. The better ones use a timing driver to regulate duration of the welding pulse, often based on the 555 timer. If you chose to make one that is based on a powerful battery + MOSFETs make sure that your driver circuitry is fed by a SEPARATE battery, not the welding one. If you use the same battery for both welding pulse and the driver you will burn your MOSFETs (or the solid state relay) in no time. Good luck with your project.
This is not worth the trouble, to much cost to build
❤️
I would insert a diode in parallel to the coil to suppress overvoltage rising during "off" of the switch. Cathode towards positive, of course ...
You try
That will make the relay drop out slower - do you really want that?
So you're just shorting a car battery using a starter solenoid. Using li-po batteries was pointless because you could thrown the relay with your car battery power. Let's hope your starter solenoid doesn't spot weld itself as it often does since they're not rated for that much current. Have a phone pre-dialed with 911 handy.
Are there other choices for the resistor besides .22 ohms? Can you suggest other values please to substitute? Thank you in advance for your response . Great video, nice close-ups, etc.
You can use .10 , .33 , .47 & 1 Ohm
Thank you so much for the quick reply. Keep up the good work. Love the video, very good camera work, etc. Thank you.
_Most_ things in electronics and even electrical circuits have a plus or minus tolerance of around 10% or even 15% on some components and the circuit will still work just fine.😉🙃
Use a higher value, at least 180 Ohms. The button will burn out soon if you don't.

after coneccting to the battery , it gets connected to a nuclear plant
Pl. Provide connection diagram there is some confusion into the connections of two types of Batteries.
Please check diagram in the video , end video
Yes me too some confusion at first glance
The small batteries are to fire the relay
For diagram 7:36
@@learn_with_naveenlakshman t shows 0,0000000001 micro seconds 🤣😂😂😂😂 WTF😂🤣🤣😂🤣
I think that the relay is a little slow, it makes strong welds ! The danger is about burning through the body of the battery!
No damage problems battery
Why do you have those three li-ion batteries (12V) separately for the relay's drive coils when you could use the same big 12V battery as for everything else? They are just an unnecessary expense.
Li ion battery use for puch bottom
Was wondering the same thing.
If you look at the circuit you will see you're actually shorting out the 12v lead acid battery when welding. This could drop the voltage and the relay would then let go. Then the voltage would ride again and the relay connect and so on.... You'd have made a buzzer!
What happens if we use 12v dc adaptor instead of batteries
@@drsudduu You can if you have high current rated adapter. For spot welding you need high current.
Sy sudah membuatnya mengikuti video ini, tapi kenapa tidak ada keluar percikan api dan tidak ada sama sekali hasilnya..??
saya menggunakan aki 12v -5amp.. tolong saran nya......txs
Please use minimum 18Ah max 40aH 12v
Very nice and professional video. It's coming on the right time coz i really intend to build a spot weldering device.
Thank u very much for your compliments ❤️
为什么非要多用三颗锂电池，直接用电瓶的12V电压控制继电器不行么？
For puch bottom, you try, you will understand
Entonces al ver el diagrama me doy cuenta que aún sin el relay se puede acer los puntos solo con la batería de 12volt y el capacitar en paralelo con la batería lo importante es la corriente para poder fundir el nickel
Relay work --- only switching
Hi friend. I just want to tell you that I like your projects and I get inspired by them. This is what I need right now so it's great to have someone like you here.

Oi meu amigo, é o seguinte o capacitor é só comprar uns 4 de 3300uf por 25v custam uns 4 reais cada e ligar em paralelo, já a contactora pode usar de micro-ondas é um relê potente que aciona o magnetron custa uns 25 reais, já este projeto tem alguns problemas, é solda por curto e implica um perigo, inclusive de explosão da bateria por não ter limitador de corrente, outra é se a ponteira colar e a chave de acionamento travar ou derrete tudo ou fundi a bateria, circuito mais acertado seria uma lâmpada em séria com a ponteira para limitar a corrente ou melhor entre a bateria e o capacitor isso faria uma limitação na corrente de recarga do capacitor no acionamento a corrente do capacitor efetuaria a soldagem a lâmpada acenderia e não drenaria a bateria em corrente máxima ao soltar o botão a bateria recarregaria o capacitor para um novo ciclo de solda, e outra a corrente fluiria de maneira mais segura para o capacitor aumentando a vida útil do mesmo. Eu mesmo já botaria um disjuntor na saída da bateria.
@@azlirameliasdasilva4662 Valeu!
@@azlirameliasdasilva4662 A grande ideia do autor do vídeo é usar o automático de partida pra fazer a conexão, daí permite n variações. Achei importante a sua ideia de reforçar a chavinha com um rele. Já fiz uma ligação provisória no meu carro para dar partida mandando 12 volts para o automático (o comutador da chave tinha estragado) e o fio meio fino ficava quente, deve puxar 10 amperes ou mais, essa chavinha corre grande perigo de colar mesmo. Mas eu já improvisei solda a ponto com capacitor de 15.000 uF x 63 e 12 volts é pouco pra soldar só com a descarga dele, começou a dar certo com mais de 30 volts. Portanto infelizmente vai ser necessário a alta corrente da bateria, os fios relativamente finos (mais finos do que o fio que alimenta um motor de arranque) devem limitar a corrente o suficiente para evitar a explosão da bateria, os tempos de descarga são curtos e se forem feitas muitas soldas é bom verificar se ela não está esquentando. Outra ideia é usar uma plaquinha step up para aumentar a voltagem ou uma fonte fast (sem transformador) com um zener para limitar a voltagem para o capacitor, lembrando que fontes fast não são isoladas da rede e as ponteiras vão dar choque. Nesses dois casos o capacitor é quem vai fornecer a corrente para soldar portanto é importante limitar a carga dele com um resistor de 1K x 2 watts para não queimar o step-up ou a fonte fast.
Непонятно - зачем литиевые батареи в цепи управления реле... Я считаю можно было использовать те-же 12 вольт которые мы имеем от большого аккумулятора.

VERY _clever_ circuit design! I even happen to have two Nichicon 80v 10,000μF caps laying around to use for this! And at 2:12 what is THIS? Someone who knows how to _properly use MORE FLUX_ to get a better solder bond?! Unlike 99.9% of other videos on RUclips that haven't got a clue this stuff even 'exists', let alone how it makes your work _so_ much easier because of a MUCH faster _HEAT_ transfer with a liquid!?😎
You can try with your capacitor, Best maximum 4700 - 6800uf

@@SheikhN-bible-syndrome wire them in series/parallel until you have enough voltage/capacitance. Do an image search "series vs parallel" and it'll show battery wiring diagrams and how connecting + to + and - to - vs - + changes the voltage and capacity/amps.
@@SheikhN-bible-syndrome just be _REALLY CAREFUL_ not to get shocked by that kind of voltage/capacitance... ☠️ ⚡ I would recommend covering all the exposed terminals ETC with liquid electrical tape, a couple coats of latex paint or similar protective covering.
@@macgyver5108 I know a little bit about Electronics I've been doing car audio for about 15 years and I just started building simple Class A solid-state amplifiers I just can't figure out a timing method to time the output for spot welding I know not to just charge the capacitor up and then connect to a gauge wires to it and just short-circuited on the middle LOL I need some form of controller or learn how to build a controller I've also got a bank of super caps I made out of 6 500f 2.7v caps which can take up to 16.8v and a little over 100f but its probably getting used when I figure out how to make a miniature magnet charger for making my own little magnets.
Correct me if I'm wrong but I shouldn't worry about getting shocked until the voltage reaches over 48v on those capacitors correct? Or can I still get a zap off of something in the 16 Volt range?
Why not use the same 12v source to switch the relay and power the capacitor/welding?
You try, u will understand
The action of welding shorts the lead acid battery. The relay would let go.

Hi, please what is the battery protection diode? What are its parameters? Michal
Very misleading. In reality success depends on the amperage AND the pulse duration. It is impossible to control the pulse duration manually since it is varies from 10 to 16 msec [or so] depending on the material and thickness.
This is a only a make-shift [sh&tty] solution. What is sad is that a couple dollars of additional parts wouuld greatly improve it.

Yes, but not work properly , you try, understand
Why is the capacitor needed? Does the battery not deliver enough current without it?
Save for battery life
Why the redundant power supplies? You have a main 12v battery, yet you use three 3.7v Lithium Ion batteries (11.1v) to power the control circuit. The control can be powered off the main battery, perhaps a 1 amp fuse wired in for safety. Even adding a fuse is less expensive than a battery holder plus three lithium ion batteries. Those lithium batteries actually could be used as the primary battery if you only need to weld for five to ten minutes at a time.
Second, a 16v capacitor is sufficient when running off a 12v battery. The 25v minimum rating is needed when running off a 12v AC transformer, because 12v AC is 17v peaks (12v average of the sinusoid wave form)
Does work for 0.3mm pure nickel?
