I used to teach electronics and one thing i always told the students be aware of electrolytic capacitors as they can explode. Mmm good safety here

I have only seen very few capacitors explode, but I haven't seen any other components explodr
They explode if overcharged or missed the polarity of the capacitors
@@Miles-co5xm I've seen three too many, right in my face to smh.
Capacitors uses in high frequency scheme's so it will not explode if you will not short circuit with inductor.
Nice. I have seen the carbon rod obtained from two Zinc Carbon batteries used as spot welders wired up to a car battery before. The carbon doesn't stick. 👍
Parabéns pelo vídeo. Tenho alguns baterias para montar um pack e já vou utilizar a montagem..
Just as a heads up, if you use this capacitor in its as shown format and you are spot welding onto the negative plates of most 18650's you run the very real risk of melting through the plate and allowing the electrolyte to leak out, I know this because I built it and has that very problem, I have now integrated a 400 amp starter motor relay into the positive pin and an arduino uno with a 4amp NPN transistor and flyback protection diode so that exact timed pulse could be delivered and now it is a very reliable device that can be ran of a bench power supply.
Would you discribed more detail for this? I want to make one
Where did you get 400 a starter relay?
@@isminivermekistemeyenmahmut Amazon, it was a motorbike relay
@@foxabilo i mean are you sure it was rated for 400a?
@@isminivermekistemeyenmahmut sure, starter relays are short duration devices, they would not take 400amps continuous, but they are rated for 400A for 5 seconds.
Actually, this is the beginnings of a great idea! I have that same supply and I am going to experiment with lower values of capacitance and voltage such that the capacitor only has enough energy for a single weld. Then I'll leave the supply connected with a current limit setting that allows the cap to recover as I reposition the probes for the next weld. I loved the macro-views of your work too. I think this will work well and it beats spending $250+ on a spot welder that I will only need for a few days. I'll probably use some other metal than copper for the probes but I'm excited over what you have done here. Thanks!
BTW, on my supply, Every time I short the output when it's putting out over 25volts, Q2 instantly shorts; the current limiting won't save it. That's the only part that fails and It's only 2bucks, but the supply delivers up to 68 volts to the load after the failure which is no good. Up to 15 volts though, the current limiting works the way you would hope. It's such a great supply otherwise that I just try to be careful.

When I was in electronics training school, the chapter on capacitors stated that a capacitor with an air dielectric of 1/32nd of an inch would require a plate area equal to 36 square miles to be a one Fared capacitor. Obviously dielectric constants have improved over the years. When I was in school a one Fared capacitor did not exist.
Super capacitors are there since last 25years

That’s awesome 👌🏻 all you need is a dc machine which I already has to charge the capacitor, which can also be done by Mobile charger by cutting its wires, check & awesome method of spot welding 👌🏻 one of the best video i saw till date

No you can't just use a phone charger🤦 try it and report back
The limiting energy of the shown charged capacitor is found by the formula: W=CU*2 / 2 = 500x2.7 * 2/2 = 1822.5 J = 1.8225 kJ. It is quite enough to melt a small area of metal.
what matters here is power not energy
@@AlbertRei3424 Power is energy per unit of time. In the case under consideration, it is necessary to divide the found energy by the duration of the discharge. The duration of the discharge is very short (thousandths of a second), hence the energy is very high. Not only the melting of the metal must take place, but also its evaporation.
@@user-su6qf5cj2bit doesn't use all of its energy, probably the voltage dropped from 2.7 to 1.5V. It doesn't really vaporize bevause the voltage is low, maybe 24V could vaporize the metal. The amount of pulse power depends on the voltage,but too high power is not good too because we want to melt it, not to create a hole.
This is pretty cool. I have application for this thankyou

Harika fikir lehimin tutmadığı yerlerde süper olur takipteyim izlemeye devam Türkiye selamlar 👍🎁
Thanks, for this demonstration on spot welding as it was good to see. It has given me ideas now on replacing my failed Makita cordless lithium batteries
Great idea, low voltage and limited load = safe. Make a pistol for it with a trigger and contacts that can easily replaced. A base to put it in or a button to charge it. Benefits of a trigger: More control when it needs to spark and better contact to the surface when pull the trigger. I guess the spark would be smaller when doing it this way. Great stuff!
I have some concerns about how practical designing a switch for this would be. You wouldn't want to weld in place the switch terminals when commutating. Solid state switches could be an option but it would need to take a load of current and not inexpensive at all.
What is the internal resistance of this capacitor?
Depending on that, the current that can be passed is determined, and the power consumed by the ridge can also be calculated.
I would like to know if a supercapacitor can withstand such a current.
Alternatively, ordinary chemical capacitors can increase the voltage, so even if the capacity is small, a large amount of power can be extracted.
I want to compare it.
What is your answer?
What is your answer?
Another option is to use NiCd or Lithium batteries.
they have extremely low internal resistance, that's what make them so special. Li-ion can't push all those amps you see in the video.
Buen vídeo,no se me había ocurrido.
Amazing brilliant stuff thank you for sharing God bless
Notice the weld works better making the positive connection first.
what's the difference?
@@petaabay3984 possibly the flow of electricity like DC current goes from positive to negative and by having the positive side down first helps at least I’d guess anyway I can’t remember if that has something to do with a certain kind of welding or if that welding just was being grounded by the cable always attached. But no one else gave you an answer so I thought I’d give my educated guess
Items you need to make a DIY welder:
1 welder
You need money,

Wuih 500F,pengen dong untuk bikin spot welder
こんなに簡単にスポット溶接出来るなんて驚愕！ good!!!
bridging the contacts is prohibited to discharge the capacitor !!! Only smooth discharge (for example connect an incandescent lamp)
Евгений capacitors are designed for such uses... a lamp (incandescent) will not work, it’ll short it out essentially creating a flash bulb... the tungsten wire (filament) will not be capable of handling high discharge rates.
@@BeezyKing99 no, not really. Shorting the cap might burn inside leads.
The way the batteries are wired up makes them short out. The outcasings are touching
I think they are already dead
I agree, there are several notes that should have been mentioned, rather than assuming the viewer knows what they are looking at.
to tell the truth this is what I ve ben searched for the easyest and the cheapest spot welding ever seen really very awesome and nice good job bro .thanks a lot

super idea.it's working amazing
Obrigado pela demostração! Muito bom!!
Learn to solder. Lose the music. Discharging a capacitor like this will lead to failure of the capacitor, possibly rupturing. This video is not to be recommended.
I thought the same thing, will they show the video when they blow a finger off?
Dr. Safety, making up there making sure everyone knows to solder their batteries. One things batteries love is longer exposure to high heat.
Like I agree with you on the cap, but the two things he spot welded were batteries and stainless steel. Everyone knows soldering steel works super duper good.
i agree with all the replies, heehee
Indeed super caps are actually quite weak compared to a good LiPo these days, maximum (rated) peak currents aren't that impressive.
But I suppose as long as the failure mode is a safe venting (or just a degradation of the capacitor) killing a few could be justified for the reduced cost (compared to a real battery welder)... but I must admit that I don't know if that is the case if abused hard enough.
Also it would be interesting to do the math and calculate the resistance in the copper wires prior to building such a thing to see just how bad the peak current might be.
If I guestimate 3mm diameter and 8 cm total length an online calculator says 0.2 mOhm or 13.5 kA @ 2.7V .... However a 400F GreenCap capacitor has a rated DC ESR of 5mOhm dropping the theoretical max down to 519A @ 2.7V which is still above the rated max peak of 180A by roughly 3 times.
519A @ 5mOhm equals 1346 J/s, however 1/2 CV^2 = 1822J @ 500F, 2.7V in other words if the capacitor is capable multiple welds it would indicate that the actual current is lower than 519A .
Also as a side note: Does GreenCap make any 500F snap in capacitors :)
Can't lie... That's genius
Impressive and powerful, and a bit wild!
2000 joules, and several hundred amps...!!!
I have a bunch of these, I'm thinking I'll wire them in series/parallel with an automotive solenoid as a high amp switch, I'll try different configurations as in series and parallel until I get a good output. Also like in tig welding maybe take the positive and clamp to whatever I'm welding and the negative attached to a tungsten electrode before making contact with the welding metal... Trying to find a diy way to weld aluminum... Might explode too 😬😬😬💥😆
The main problem with copper and aluminum is how fast they can produce oxides when exposed to heat. Just remember that.
Excelente.

8:00 you made battery short circut

He just connected them in series...
That was the intention but the case of the added battery creates a short to the prior battery. Check carefully
@@AlexFrBuPi exactly
@@AlexFrBuPi yep, made me chuckle & SMH to see that. It was one of several mis-steps, but there's no point enumerating them all. Having said that, here are a couple of highlights for anyone crazy enough to want to try this at home...
1. Some insulation between the edges of adjacent cells is absolutely essential - and easy: even a bit of Scotch tape or clear packing tape would do the job.
2. It would have been better to solder two small gauge charge wires to the battery; this would reduce the risk of welding the alligator clips to the battery terminals (and burning them off!) while connecting the power supply for charging.
3. Alter the weld energy by charging to a lower voltage: remember "Q=CV" ? Burning holes in the parts you want to connect - let alone the surface you're working on - is hardly the intended outcome, even if the parts are technically connected: it's what we might call an "SODP": "successful operation - dead patient".
4. A thin piece of sheet metal (preferably iron or steel, not aluminum) under very thin target pieces - like those razor blades - would have helped as a heat sink to prevent the temperature from getting too high - and also protect the working surface!
5. Connect a resistor between the terminals when the unit isn't being used, just so there is no residual charge that might cause a spark and start a fire. A 1/4 watt device of 22 ohms or greater would be fine. At worst case of 2V charge, that's 2*2/22 = 0.182W which is enough to discharge the cap slowly while not creating too much heat.
3:25 PLEASE heat up your soldering iron more
Cold joint
It's also lack of flux.
... And a 'Tip' Use a better Tip. Those conical tips are next to useless.
Muy bueno el video, lo voy hacer, gracias

It's just 2.7 volts.
Nothing happens until metal short circuit
@@353click I know 2.7v but have you forgot the Amps can do big damage too specially on the capacitor . Just make sure don't touch capacitor unless you know It's discharge first . :)
@@pham92115 no it's amperage through your heart that kills. There is no amperage without a low enough resistance or high enough voltage across it. While the internal resistance of your body (the wet stuff) is about 300 ohms and at 2.7 volts would push 9 milliamps through you, your dry skins resistance is closer to 100 kohms this means a current of 3 microamps would flow through your skin if you touched it.
If you've ever touched a 9-volt battery or a car battery you should know that without touching internal tissue (like your tongue) these voltages cannot hurt you.
@@353click ok thanks , anyway I'm scare to mess around with those capacitor unless I know It's discharge first :) because I'm not sure how much current has in it :)

Wow, I never knew low voltage can be used to weld also
It IS AMPERAGE that represents power.

Nice project. Very useful
