@@georgestiell7740 . The only reason for a diode in a dc circuit of this type would be to protect from any back emf generated by an inductor such as a relay coil but short circuiting a battery is definitely not recommended. That is a universal instruction that accompanies all batteries. An 18650 spot welder works on low voltage and high current usually by the discharge of a large value capacitor to give a short duration high current pulse.
It's not a short circuit because he has a diode as a resistor on the plus terminal of the battery. It's a LOAD so it's wrong for you to talk about a short circuit.
@@lyndonp6296 That's a 6A4 diod... it's common diod that comes in at 6 amps at 400 volts... that's a 2,400 watt diode. It will survive that little 6v battery ... it's there for back flow protection to keep the battery from heating up... it's still a super unsafe build, but the diod definitely didn't fuze... in fact diodes can't fuze into a conductor because of how there constructed... it would glow red hot, let out it's 'magic smoke' and loose it's conductive properties then the glow would go out and it would just be a dead diod.

Good product but what you need is some sort of fast switching mechanism.. Otherwise the current is too high to utilise and it will damage the part to be spot welded. Shorting the battery for a long time may even damage it. You can use a 200 amp relay as a switch.
Great for a cheap spot welder, but I suggest you do NOT use it on your battery packs! A fraction of a second too long and you are going to damage the cell! :(
Should have one contact on base metal and other on the piece to be attached. Putting both on the same top strip makes a short circuit and does not create a spot weld between the 2 pieces of metal..
The diode is stupid and didn't survive. Do you see it in the end demonstration? No... it blew the first time he tried it and it served NO PURPOSE to begin with.

"Positive electrons", eh? Just out of interest, what's the diode for? Is that in case you are spot welding batteries to maintain polarity or is it acting as a resistor?
@@jeffcantley9203 that's because the resistor is the point of highest resistance! Just like the probes touching the metal is the point of highest resistence, therefore the wires don't melt first...
@@Quickened1 Just like the path of least resistance is not the only path for current, the highest resistance is not the only resistance. Considering the large currents in this ridiculous "spot welder", Sourav has made a correct observation. In every case, the connections should be mechanically sound before soldering. Solder is not intended to be the current carrier as it's typically 5 to 10 times the resistance of copper, depending on the alloy used, with a much lower melting point than iron, which is about 4 times the resistance of copper. The diode that was soldered in place was absurd. Not just because it was soldered in place, but because there is no way that diode is going to handle the current... and since it's missing at the end, it definitely didn't survive. Never mind that is served no purpose. THIS is why people who make videos on UA-cam are often dangerous. You can be king of the blind with partial sight in one eye and blind in the other.
@@DiffEQ I agree that this device is a joke, and it should only be used in an emergency, life or death situation. I was just stating the reason the solder would likely not melt, and if it did, so would all the insulation and just about everything else. You're right, a lot of dangerous people posting on UA-cam...
The materials and construction are just foolishness. Diode soldered directly to the battery lead? WHY? Maybe this guy is laughing his head off just thinking of all the idiots who followed his video only to have a semiconductor fry/explode in front of them.

@@ramadhanmohamed8684 do it as it should or dont do it at all....its not about you or me...i dont have such DIY videos, but if i did, believe me, i would go much deeper into the matter of safety and functionality after all....just like i said, your project would be a 1 light year bette only if you did use a tig welder electrode for 1$ only....nail vs tungsten is not even comparable....and if you live in country where the nail is available and battery as we saw, believe me, there is a tungsten electrode available as well ;)
Why are the solder joints not melting? It means solder has higher melting point than iron or aluminium and if it is so then we can use soldering iron for welding
That's because soldering tin has lower resistance than steel he spot welders it, but honestly this video is a junk. Someone with enough understanding will know there is no diode needed for DC current.
rather than spending a few bucks on batery and other pieces, i spent the money on far more practical and safe spot welder that can act as a powerbank as well =D
What if we parallel connect ten 1000uf capacitor and charge it with this battery and then use that charge capacitors as a spot welding machine. Does it work or not?
It seems in India everyone just has every type of capacitor and switch and resistors just lying around , what a great place to be . Thanks alot fry's electronics.
@@edisonmanimbao6110 You just accept his answer as correct??? It's not... the diode serves no purpose and DEFINITELY does not prevent damaging the battery. The materials and construction are just foolishness. Diode soldered directly to the battery lead? WHY? Maybe this guy is laughing his head off just thinking of all the idiots who followed his video only to have a semiconductor fry/explode in front of them.
I don't see the point of the diode. You could probably omit it. It does reduce the voltage a bit but you'd likely get stronger spot welds by removing the diode.
Its for safety, because in theory works as current limiter. If I don't remember incorrectly 6A4 stands for 6 Amperes 400v. So actually, I would like to get one around 2 to 4 Amps max since this would reduce the chances of the battery exploding in my face. If u want to do this, make sure u put 2 diodes in series so if the first fails and short circuit, the second will buy u enough time to disconnected the terminals. Edit: No, losing 1v doesn't matters, if anything it will help u to avoid sparks when welding.
@@simjang-9171 Diodes don't do any sort of currently limiting. The current you're mentioning is just the max those diodes can handle continuously before they burn. The main thing those diodes will do is provide a small voltage drop, which would reduce the current but its not current limiting by any means. The main reason for such diodes would be to prevent reverse current but you're dealing with a DC battery, not AC, so, diodes are unnecessary. Besides, you're building a spot welder. You want higher currents. If the current is too low, nothing will happen. So, why would you want to limit or reduce current? If its too powerful, just reduce the time the spot welder is on. Instead of 1 second, you do 0.75 seconds or 0.5 seconds. The less time the spot welder is on, the less likely you'll damage the cells, so you have nothing to lose by having a more powerful spot welder.
Soldering a wire that will heat up to hundreds of degrees Celsius? Note how the timber handle is brown from the heat... releasing all those toxic fumes from the burning epoxy. This a children school project that should be supervised and then disposed of by a responsible adult. But with millions of views the clever creator is enjoying the $$$ of his effort
You have to give it to them , they can make a soldering iron using a soldering iron (with the dirtiest tip) and a glue gun and a coke can and a little Indian magic lol 😆 😉 😀
If you make a pedal that will create a quick contact you will have some more control and not stick your electrodes and melt everything. Just tap the pedal quickly.
What is the diode? Since it is DC, the current can only flow in one direction anyway! Wofür ist die Diode? Da es Gleichspannung ist, kann der Strom sowieso nur in eine Richtung fließen!
You shoewd a good video but you dis not mention the item and its specification of tge electronic vomponent you welded to the batterg. thst was the most helpful item
Learn to type! By reading any further you agree to assume all liability and responsibility for your own actions and what you decide to do with this information. That being said, it's a "6 amp, 400 volt, rectifier diode"... If you could not figure that out on your own, than you should not make one of these. I told you anyways because I believe in natural selection. Do with it what you will, but remember I warned you.
He needs to use steel nails for electrode to ensure better resistance than copper. If your voltage can be reduced to 3V then copper is better else battery will get damaged.Good idea though I prefer a 3V source
If that's a machine I'm Leonardo da Vinci. Usually machine consist of some moving parts, yet you have none,, it's a 2 pieces of wire and a 6V battery,,, Where's dislike count yt?!

Hey, that's some high performance sh!t right there....!
The guy just makes videos that teach you enough to get hurt but not enough to avoid it. Which is probably all he knows too. Shouldn’t be posting stupid ideas like this. Someone who doesn’t know anything about electricity and what is safe will try it because it looks so easy and simple. Dying is easy and simple to do too.
That looks kind of dangerous ... looks like it's very easy to short that battery and cause it to explode :(
Bhai diode konsa used kia h esme
"Positive electrons", eh?
Just out of interest, what's the diode for? Is that in case you are spot welding batteries to maintain polarity or is it acting as a resistor?
What is rating of diode used here?
Bad idea rating
Very nice,but won't the solder melt inside the probe covers?
No because that isn't the point of highest resistance.
@@jeffcantley9203 that's because the resistor is the point of highest resistance! Just like the probes touching the metal is the point of highest resistence, therefore the wires don't melt first...
@@Quickened1 Just like the path of least resistance is not the only path for current, the highest resistance is not the only resistance. Considering the large currents in this ridiculous "spot welder", Sourav has made a correct observation. In every case, the connections should be mechanically sound before soldering. Solder is not intended to be the current carrier as it's typically 5 to 10 times the resistance of copper, depending on the alloy used, with a much lower melting point than iron, which is about 4 times the resistance of copper.
The diode that was soldered in place was absurd. Not just because it was soldered in place, but because there is no way that diode is going to handle the current... and since it's missing at the end, it definitely didn't survive. Never mind that is served no purpose.
THIS is why people who make videos on UA-cam are often dangerous. You can be king of the blind with partial sight in one eye and blind in the other.
@@DiffEQ I agree that this device is a joke, and it should only be used in an emergency, life or death situation. I was just stating the reason the solder would likely not melt, and if it did, so would all the insulation and just about everything else. You're right, a lot of dangerous people posting on UA-cam...
INI YG BIKIN SPOT WELDING TEMEN NYA SI UCUP...
What is that item you welded on positive pole?????? Why it isnt in your components list?
That was Diode just to make current flow in one direction .
Why the diode is needed? The battery is DC not AC. You are going to burn the diode if the current exceeded its ratings.
What component you've used? Mentioned 6Au on it.
This will decrease your battery life and get spoil quicker
This video should be titled "how NOT to make a welding device"
Very dangerous!
hahahaaa that's being honestly mean
bahaya buat orang yang tidak bisa seperti kamu.🤣
Bravo . 10,000 Likes .
awhsome idea what is the thing you soilderd on the batterie called
Yeah a spot, ON THE SPOT destroyer of good battery source.
Sacrifices must be made for greater good
@@josealfredfernandes LOL..
4:33 whats that black thing ? Pls say its details ?
Diode
@@creativethinkideas NOT in the description. nice to know a type of,diode
@@creativethinkideas what happened to the diode? I don’t see it anymore at 5:00
I think his using 6amp diode
On the minuhete 5 it show that you connected the red wire straight to the + side, where is the thing that you welded before in video ?
The materials and construction are just foolishness. Diode soldered directly to the battery lead? WHY? Maybe this guy is laughing his head off just thinking of all the idiots who followed his video only to have a semiconductor fry/explode in front of them.
Very great 👍👍👍 job
In an emergency situation, this would absolutely work on light gauge materials, but it is not advisable to use this setup for long term use...
Sketchy af. Just get a $20 controlled welding pens.
@@h8GW I'm not gonna carry around a welder everywhere I go, so in an emergency, if all the parts were on hand, this could get you out of a tight spot...
Will this work on my broken rayban ? ?
Copper's electrical conductivity is unparalleled.
Why have a diode in series?
Which item fixed with red wire n battery I think it is diod? Reply please
Bhai battery me jo plus ki taraf lagaye ho kya hai kitne
Easy to see you have no idea on how to solder.
What's the two glue components that you mixed up???
Epoxy mix.
What diode did you use
A fake safety die odd from exploding battery/local news about you
what type of that little capacitor he does using ?
It's a diode.
Hi good but aapne ek device fit kiya use kiya kehte he black colour ka he vo jo

inline Diode missing from positive terminal @ 5 mins? where did it go?
How long before the Wooden handles start to smolder?
Diodanya mungkin sudah terbakar 😀
UA-cam should hire some technician experts to review the "DIY" videos and the dangerous ones remove from public view, just like this one which is crap at first point and 2nd, it doesnt work....instead of nail only electrode suitable to use is a TUNGSTEN...which can be bought in any shop with the welding equipment for TIG welding for like 1 to max 2$ a piece 150mm long 2.4 or 3.2mm thick, so you can make 2 sets of tips...
please send a link to your safer diy videos
@@ramadhanmohamed8684 do it as it should or dont do it at all....its not about you or me...i dont have such DIY videos, but if i did, believe me, i would go much deeper into the matter of safety and functionality after all....just like i said, your project would be a 1 light year bette only if you did use a tig welder electrode for 1$ only....nail vs tungsten is not even comparable....and if you live in country where the nail is available and battery as we saw, believe me, there is a tungsten electrode available as well ;)
Why are the solder joints not melting? It means solder has higher melting point than iron or aluminium and if it is so then we can use soldering iron for welding

That's because soldering tin has lower resistance than steel he spot welders it, but honestly this video is a junk.
Someone with enough understanding will know there is no diode needed for DC current.
rather than spending a few bucks on batery and other pieces, i spent the money on far more practical and safe spot welder that can act as a powerbank as well =D
What if we parallel connect ten 1000uf capacitor and charge it with this battery and then use that charge capacitors as a spot welding machine. Does it work or not?
Not the best way to weld, but its how I taught my self as young teen in my fathers workshop in a similar fashion. great memories. Thanks
ชข
sir may i know the exact specification of that capacitor you used?...
It seems in India everyone just has every type of capacitor and switch and resistors just lying around , what a great place to be . Thanks alot fry's electronics.
Hi what is that diode or resistor the one that you connect on positive side..thanks
He use diode to prevent from damaging the battery.
@@keedzulkiflykeeabdjalil3536 hi thank you
@@edisonmanimbao6110 You just accept his answer as correct??? It's not... the diode serves no purpose and DEFINITELY does not prevent damaging the battery. The materials and construction are just foolishness. Diode soldered directly to the battery lead? WHY? Maybe this guy is laughing his head off just thinking of all the idiots who followed his video only to have a semiconductor fry/explode in front of them.
Hi
Does it have to be 6A4 diode or any diodes ?
I don't see the point of the diode. You could probably omit it. It does reduce the voltage a bit but you'd likely get stronger spot welds by removing the diode.
Its for safety, because in theory works as current limiter. If I don't remember incorrectly 6A4 stands for 6 Amperes 400v. So actually, I would like to get one around 2 to 4 Amps max since this would reduce the chances of the battery exploding in my face.
If u want to do this, make sure u put 2 diodes in series so if the first fails and short circuit, the second will buy u enough time to disconnected the terminals.
Edit: No, losing 1v doesn't matters, if anything it will help u to avoid sparks when welding.
@@simjang-9171 Diodes don't do any sort of currently limiting. The current you're mentioning is just the max those diodes can handle continuously before they burn. The main thing those diodes will do is provide a small voltage drop, which would reduce the current but its not current limiting by any means.
The main reason for such diodes would be to prevent reverse current but you're dealing with a DC battery, not AC, so, diodes are unnecessary. Besides, you're building a spot welder. You want higher currents. If the current is too low, nothing will happen. So, why would you want to limit or reduce current? If its too powerful, just reduce the time the spot welder is on. Instead of 1 second, you do 0.75 seconds or 0.5 seconds. The less time the spot welder is on, the less likely you'll damage the cells, so you have nothing to lose by having a more powerful spot welder.
@@joemann7971 "probably" omit it???? It's unnecessary. Serves no purpose but to make smoke and shrapnel.
@@simjang-9171 Why did you even reply if you don't know what you're talking about? It's unnecessary. Serves no purpose but to make smoke and shrapnel.
Why on earth would you need to put the nail in a drill to cut the head of it off🤔 Not to mention you're going to ruin a perfectly good battery.
Hi
Why you did use a diode?!
Can make any control circuit. Just a small pulse to ensure avoid burning of the strip.
Yes, it needs a simple regulator other than that it is good stuff.
It need him electronic basic and back ground
after it's over..the diode disappears suddenly, right?
What Diode is that?
Soldering a wire that will heat up to hundreds of degrees Celsius? Note how the timber handle is brown from the heat... releasing all those toxic fumes from the burning epoxy. This a children school project that should be supervised and then disposed of by a responsible adult. But with millions of views the clever creator is enjoying the $$$ of his effort
Please can you tell me Why do you have a Diode in the circuit and how many amps is it.?
Why do you need diode?
Indian technology.. 😂😂
@Flip Miller no safety measures only pleasures....until that backfires.... aka Indian Jugaad
@@paneerpolice3454 💯 percentage truth you said
You have to give it to them , they can make a soldering iron using a soldering iron (with the dirtiest tip) and a glue gun and a coke can and a little Indian magic lol 😆 😉 😀
If you make a pedal that will create a quick contact you will have some more control and not stick your electrodes and melt everything. Just tap the pedal quickly.
Thank, you for you're video.
You left a key detail out.. what resistor is that your using??..
What is the diode? Since it is DC, the current can only flow in one direction anyway!
Wofür ist die Diode? Da es Gleichspannung ist, kann der Strom sowieso nur in eine Richtung fließen!
He deffo superglued those razor blade pieces together 🤣 you can see them move after hes finished heating them up
Diode on +ve terminal?
Hello I'm your 1 millionth subscriber your videos are amazing
Well the thing is it worked, but it would be my last resort on earth when doomsday arrive 😂
Great Idea! Diode put .....I do the same but instead of steel I put pure carbon
It'll work but keep the fire extinguisher nearby haha
Stainless lang ba ang kaya niyang I weld?
Super very good 👍👍👍👍
What diode is used??
It fried so he removed it.
Look at the video
Batery will blow up!!
What is a fever caused by?
You shoewd a good video but you dis not mention the item and its specification of tge electronic vomponent you welded to the batterg. thst was the most helpful item
Learn to type!
By reading any further you agree to assume all liability and responsibility for your own actions and what you decide to do with this information.
That being said, it's a "6 amp, 400 volt, rectifier diode"...
If you could not figure that out on your own, than you should not make one of these. I told you anyways because I believe in natural selection. Do with it what you will, but remember I warned you.
Bai diode konsi hai zener
He needs to use steel nails for electrode to ensure better resistance than copper. If your voltage can be reduced to 3V then copper is better else battery will get damaged.Good idea though I prefer a 3V source
Lityum batarya yapıyorum. Güzel fikirler ilgimi çeker. TÜRKİYE
not bad, next time use this battery recondition idea ...
If that's a machine I'm Leonardo da Vinci. Usually machine consist of some moving parts, yet you have none,, it's a 2 pieces of wire and a 6V battery,,,
