"Impressive DIY Innovation! This video showcases the ingenuity and creativity of the maker community. Building a spot welding machine from scratch is no small feat, and it's inspiring to see individuals taking on such technical challenges."
Glad that you're back again!!!
😊
This project is very good!
excelente trabajo, muy bien hecho gracias por ello desde España
Nice tutorial for diy spot welder. It is a clear and full video. Your skill is very well.
I have done about 50% of building a spot welder from oven transformer. Output test about 3.6v. I think it take me a day for all. Thank you so much
Зачем ты это сюда написал?!
@@villishon8921I was learning to do the first microwave transformer spot welder when I wrote it. Now my project have done and it work really well.
Great work!
Nice technique for making the electrode clamps.
Thanks, very good 👌
Obrigado pela dica!
OK thanks for sharing your project, I have the parts and prepared my transformer so IU will built it tomorrow.
How is your welder working?
Apne bhaut accha device banye hai. I like your work🎉🎉🎉
Very interesting. Thank so much !
quick question, the cable that you used in the secondary winding, I noticed toy used 2 core of that size cable, can you tell me what sort of current you were expecting to get out of that transformer and what voltage, and since you used that size cable why did you reduce it in the size that went to the welding tip
Nice video, thanks :)
you did a clean job👌
I made the same thing, with the same module in my channel. It worked 😊
excellent job. thanks to share your idea...
C’est formidable 👍
Excellent, all the best and keep it up....
Hello. What size is copper round for soldering? 3 or 4mm?!Cheers
I like this video thank you for sharing it to view and i wish your channel more successful
Good work
Your work is so clean...❤
Although I am fine with soldering my 18650 or using a holder for it. However I am impressed with the way, you have built the spot welder. Kudos.
i soldered batteries too, and no problems(i corrected myself)
Very bad idea to solder directly onto Lithium batteries!
The heat can melt/damage the insulating separator foil inside the cell, as well as boiling the electrolyte and causing venting from over-pressure.
It's OK to solder (quickly) onto welded tabs already on the battery. However, the casing of the battery is a huge heatsink so you need to dwell a long time to get enough heat for solder to melt. This causes the damage to the cell.
Much better to spot weld on bare (new) cells because the duration is far shorter, so less heat gets inside the battery cell.
@@makantahi3731- do you weld or solder? They are two completely different things, and the OP was talking about soldering.
@@johncoops6897 i soldered many 18650 lion batteries and no problem
Hello brother plz send the board buying link thank u
What gauge of wire has been used at the secundaire part of the transformer, how much "VA" was the transformer? What voltage comes out at the secundaire side? Very nice for a hobbyist, many questions for profecional technician!
wao thank you for providing value
The value of these videos is priceless. Thank you so much for making such detailed tutorials! Next, can you make a video on how to make a Flux Capacitor for a Delorean? 😄
Just retrofit a continuum transfunctioner if you have one kickin about.
O'Reilly Auto Parts Part # 121g
C’est très bien 👍👏
if you put a coil with 2-3 turns on the end it could also double up as an induction heater
That Good and Number one for you ❤❤❤❤
i've been subbed for quite a while, always love seeing these really interesting and impressive videos, dude.
Son muy interesante y se aprende mucho
super good...put good rubber handle, gloves too...safety first.....
Hello! Thank you for the video. But I don’t understand where to buy such a control board! Nothing on the website is clear at all.
Buen trabajo 👍
top exelente maravinha
Muito bom ,
how many volts and amps. the adaptor powering the trigger circuit?
You made a mistake in executing the welder machine.
(I made the same mistake.)
The red and black wire are very thin and reduce your current from the transformer .
That's why the weld is weak.
Double those wires and you'll get a strong weld .
Yesterday I made a video demonstrating this. (this mistake.)
I put a 6 mm wire in the transformer, and at the output I have over 600 A .
But since I put 30 cm of 3 mm wire, the current dropped to 350 A.
I will upload the demo clip next week .
Video
there will be some loss in the high temp silicone wire, but its not much, the cable thats in the transformer is doubled up and thicker so it should be fine. if they used the red and black cable inside the transformer then you would be correct
Good job
Verry good..
Sehr gut!
friend, beautiful work, I'm trying to make one like it, a question, you bent the wire 10mm and gave 3 turns in the transformer? right?
50 мм
Thanks for the video. There was just one detail missing. You need to make a jumper between GND and GND_T. Other than that, it's a great project.
GOOD ONE
Parabéns.
Hej kolego , skąd masz projekt timer dla tej zgrzewarki?
Very good
Very good video Tapendra bhai. nice project. How much will it cost ? can you give an approximate budget?
I like the way you built the handpiece, though I am not sure how long copper would last, perhaps Tungsten or Beryllium-copper instead?
Hello! Thanks for this vidéo i will try it this week 👍 so what section of câble you use, is it 25mm2 ?
Can you post a link to the timer circuit?
Esses transformador tem uma amperagem alta .
Eu também faço projetos com esses transformador
I like your video
Good project. Could you give me the purchase link of the timer please ?
Have a close look @ the timer and you see HW 521. Google it and you'll find.
Search the usual online markets. They are widely available, and there are only a small number of models I total. The ones with Blue LCD screen and 100A SCR are the best ones, as they offer dual-pulse with duration setting for both Pre (cleans the surfaces) and Main pulse.
perfect
Bhai iss machine ko kya baad me as arc welding machine use kar sakte hai kya
Awesome
Could you please provide a link to the electronic part that connects to the microwave adapter?
Timer delay circuit
good
Dear engineer,thank you for sharing video,I wanted to know the spot welding transformator input is 12 volt DC current or 220 city AC current?
AC in AC out
Would you also share the board desing, please?
I don't understand one thing. That card is programmed at 0.5 seconds for example. If I keep the button pressed for longer than the set time, does the card disconnect anyway? Because I have another timed relay, but if you keep the button pressed the contact remains closed, even after the set time.
Very good work and perfectly explained. Just let me know the size of the cables used and if instead of the timer is possible to install just a trigger. Three seconds could be as well be counted mentally. No words were needed. Thank you. I did subscribe
Bylo nastaveno 0,3 vteřiny. Za tři vteřiny by akumulátor explodoval.
he didnt fkin explain anything. might as well have videotaped a blank screen
Bel video ben fatto ma per il materiale mi fai sapere dove acquistarlo grazie.
please what are the sizes of wire and fuse rating you used in the video
Hello, what is the reference of the timing module, or characteristics to request, thank you
What are the copper plates glued to?
Amazing well done that works perfect. I saw some coments asking for the size of electrodes, this is not a welding machine this is spot welding no needs electrodes
It indeed has electrodes. Check this effect you have: en.wikipedia.org/wiki/Dunning%E2%80%93Kruger_effect
Whats the settings for timer delay relay module?
Channel ka name dekha to nostalgia aa gya ..5 saal pehle video dekha krta tha
Please tell me, can I use a relay switch instead of the PCB? I need use 120Vac for primary. Can that work? What is the secondary volts and amp output? Seem like 3 coils on secondary create too much dangerous volts. Most diy builders use 2 coils. Opinion?
Relay will fail very fast, due to the huge inrush current of the transformer.
You need to use 120V mains supply if you use a 120V primary.
The 3 turns gives about 3 Volts output, safe enough to touch onto your tongue. Using 2 turns reduces the voltage to about 2V so you need more current and time to make the same weld penetration.
It doesn't really matter how many turns, having fewer turns just means you can fit larger secondary cable inside there, however bigger cable costs more and is more difficult to insert into the secondary.
Whether 2V or 3V it will still need adjustment for welding duration, so it really doesn't matter either way.
❤❤❤ God bless you
Muito bom.
Quanto de voltagem w amperagem eata saido no secundário
3 závity - nedokončené - (viz video) u lepšího MOT dají 2,6 Volt.
Bhai, the device you have made is really great, I have tried it at home and I have created the same for myself, but there is one information is missing in your blueprint of design for the connection of the timer circuit " a jumper need's to be set between GND & GNT_T of that module then the trigger mechanism will work else it won't work", please rectify in your Design properly and publish once again the blueprint.
Corect !
@@ibrahimsiddiq4102 first of all this is not my page, I don't know how to share the picture here. Else I would have share it already here. If you know how to do that please let me know.
Ravi I still your reply, please reply me thanks
Schéma svp
крутая вещь!!!! только если есть все комплектующие))))!!один трансформатор может стоить очень дорого))))!!! а так все классно сделано!!!
could you please upload its wiring diagram, specially input and output
sir, do I replace the tranformer 10 a ,that's what I have at home
Good ❤👍
good ...
How many volts do you have at the secondary output?
Did you find out, I got around 2.5v
Hay đó bạn
These guys can just summon huge amounts of copper from nowhere
Please, share PCB circuit. Thanks.
Bro finally remebered he has a youtube channel.
Ja tinha vasculhado no RUclips atras de alguem que tenha usado esses temporizador em silda por ponto
Sera se eu usar 2 tranformador ele aguenta sao 1100w cada na rede 220v
Реле в плате управления на сколько Ампер? Если на 10…16 Ампер, то думаю его нужно усилить, заменив на более мощное изделие. Ибо токи в первичной обмотке хоть и кратковременно, но могут быть больше 16 Ампер.
Cool
Thicker and more winding amplifier current
Привет! А есть такие контроллеры времени на АлиЭкспресс? Как их найти там? 😊
Hi, i did everything the same and i dont have any voltage on the transformator... the trigger is working. What wrong?
GOOD WORK I HAD YOUR DIY INOVETION ARE IMPROVED
Thanks bhai
Благодарю!
I want to know how much watt input that you used?
buenas mi hermano como estas, mire tu video del soldador de puntos y me gusto, yo ya hice el soldador y trabaja muy bien pero me gustaría si es posible decirme el modelo de la tarjeta electrónica y donde comprarla porfa
It' xy-j02
Good
The only issue in this tutorial was using small wires. The timer board is an optional and it is good to have one if preferred.
What section do you use
Is there a link to buy the timer circuit 🙏
amazon
Cuál es la tarjeta controladora que está usando?
