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.
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 .
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
very nice video and simple enjoyable work! with nice background music!!...Now I want to make one but Im unpleased that my mother threw the small kitchen she had to cook. and I cant get the coil. lol
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
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.
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
Your transformer is too weak. You should use a long timer to solder the battery cell, the soldering points will burn and not be secure. I built it the same as you, the primary transformer only uses about 180 volts and the secondary coil uses wire over 10mm and combined with a 0.01s timer, the welding is very solid. You can refer to my channel for more information
Good spot welding cannot be done with 3 Volts. Because the voltage is low, you have to extend the time. 0.3 seconds is a very long time for spot welding. If you keep the time too long, you will burn and deform the nickel strip. Instead of folding the cable in half and wrapping it in 3 turns, wrap it 6 turns in a single layer, so the voltage will increase and you can make a much better spot weld by reducing the time from 0.3 seconds to 0.1 seconds.
Провара нет потому что: 1) Слишком тонкие провода от транса до ручки. 2) Не плотное прилегание контактов, они должны быть подпружиненные, 3) По хорошему должен быть двойной импульс, таймер такого не даст. И не плохо было бы хотя бы 3 витка, но из за отсутствия хотя бы 25го квадрата, много места теряется на изоляции, надо было снять изоляцию, сложить провода и засунуть в термоусадку, тогда бы смог засунуть 3 витка.
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.
First of all - ridiculously small wire gauge in the secondary winding, it should be at least 25 mm2, on the tip of the soldering pen can be reduced to 16 mm2, but no less
@hramota: This video is a fairy tale for adults, I say this because I built it for a test a long time ago, but unfortunately the result is not suitable, but I used a much thicker wire for the primary coil
Hello. I am also collecting the materials to make. I'm thinking of using a 25mm2 cable, but I'm confused about the amperage value. In some videos they used 35mm2 cable. The copper part of 25mm2 cables is 6.8mm. I think this is not enough. When you peel off the outer shell and fold the cable in half, the copper part becomes 13.6 mm. Do you think this is enough?
To ani zdaleka nemá. Nepoužívá lisovací kleště a místo mosazného šroubu s podložkou dá na oko šroub zapuštěný se zkosenou dosedací plochou. Tam musí být ohromné ztráty přechodovým odporem. Také to relé v časovači dlouho nevydrží, MOT má tvrdý proudový náraz, kontakty relé se brzy svaří dohromady a nebo upálí.@@makantahi3731

Está todo muy lindo. Pero ahí el chabón se manda una garcada casi imperdonable. Los cables de conexión son mucho más finos que las barras de cobre , con lo que deja de tener sentido el grosor de esas barras sino también los cables del bobinado. Resumiendo : esos cables deberían ser de una sección apenas menor que los del bobinado. Porque así como lo armó; hacen de resistencia y se desperdicia potencia al pedo. Por lo demás: la idea está muy buena.

Damn dude got 3 hands. What an awesome defect to have.
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.
Why bridging the ground ends?
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)

I fully agree with you. Why use smaller gauge wire from the transformer to the tips? If I make this, I will use same wire all the way to the tips.
Very good!
How many times can I weld without producing heat in the transformer?
OK thanks for sharing your project, I have the parts and prepared my transformer so IU will built it tomorrow.

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.
Why you make those cables so thin? Why did you then run double wires thru the transformer?
I made the same thing, with the same module in my channel. It worked 😊
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.

Can you add size of the copper to the description? Thank you! :D
there is a possibility that the button or relay will fail, they may remain closed and you will have to quickly pull the device out of the socket.
Maybe a switch would help ?

Why don't they try to use "a belt" made of copper or aluminum, but do the job with a flexible wire?
How many volts do you have at the secondary output?
Did you find out, I got around 2.5v

What is the maximum weld thickness in millimeters?
Very small, in low melting point metals, maybe 0.01 mm, but ok for this. Consider the melting point of the electrodes, too.
