Spot Welding Machine Using Lead Acid Battery

   No more than 3-4V.

2. 

   If you make one of the probes to have a greater surface area then only 1 spot will get hot instead of both contact spots.

3. 

   Great Idea! Diode put …..I do the same but instead of steel I put pure carbon

4. 

   Great achievement. Keep it up bro

5. 

   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?!

   Nice 👍🏻👍🏻 🇮🇳 || Kuki.

7. 

   it's not good for battery life There may be a risk of battery blasting

8. 

   What was that thing that you connected to the positive terminal of the battery, to the wire?

9. 

   But how to make use welding sticks….??

10. 

    this person is fooling people

11. 

    Battery kitne volt Ki Hai

12. 

    Crap! 😎

13. 

    You are lucky the battery did not blow up in your face…
    Direct shorting out the battery as you were…

14. 

    You are a liar and a deceiver, where are the diodes?

15. 

    The fixture of the nail at 2:00 is great art work! Thats whats the electrician wants to see! A connection capable of really high current – just as you need it for spot welding! But wait – its going to be even better: the diode – poor thing! Why the hell would you need a diode here??? Its probably melted to short circuit now – thats why it still works 🙂

16. 

    What is the specification of the diode ?

17. 

    Make your spot welders from microwave transformers

18. 

    Cel mai prost tutorial pentru un spot welder 🙂 nu recomand asa ceva mai ales folosit pe acumulatori 18650 🙁

    Not follow any safety this video maker

20. 

    it doesn't seem to me that it works very well …..

21. 

    Unbelievably crude…

22. 

    Saya lihat. Pertama kabel merah di sambil ke accu plus. Menggunakan dioda. Pas pemakaian. kabel merah tidak ada dioda.

23. 

    You left a key detail out.. what resistor is that your using??..

24. 

    I've had a drillbit go through my fingerprint pad so must be careful!

25. 

    Youtube 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…

26. 

    not bad, next time use this battery recondition idea …

27. 

    Why is the diode you soldered on the + side not on any longer when you were spot welding???

28. 

    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

29. 

    Oh No!

30. 

    Please don't do this at home (or anywhere else!).

31. 

    For a $13 spot weld kit, I'll pass on this. And people wonder why in Canada we make immigrants essentially re-educate themselves to prove proficiency in their field. This is why.

32. 

    Try this trick on lithium cells and tell your buddy to upload to YouTube. Because you won’t be around to watch it.

33. 

    That’s not welding anything durable

34. 

    stainless steel does not take solder like you show.

35. 

    In the last part of the video the diode you install in the possitive terminal on the battery is missing…why?

36. 

    இதை வைத்து இரண்டு நிமிடம் வெல்டிங் செய்யலாம் 0.5மிமீ க்கும் குறைவாக உள்ள மெட்டலை மட்டும் . பேட்டரி யை இவ்வாறு நேரடியாக பயன்படுத்தினால் பேட்டரி யை குப்பையில் தான் போட வேண்டும்.

37. 

    inline Diode missing from positive terminal @ 5 mins? where did it go?
