Home-made spot welder (very powerful)

Hello guys… and a few girls… :) I finally have a spot welder; a powerful one.

    Superb Video. Very clear, step-by-step build, with concise explanations, which include dry humor and feline assistance. Thank you, Sorin.
  • @Delali
    This is a great build. Very simple and super useful. I have been thinking of getting one of the prebuilt portable ones for my channel. However this looks great too. I might try your approach and make a video for it.
  • @drabusharr
    Excellent video for instruction, very professional and awesome audio explanation with clear video. Many should follow your style. Your assistant is also to be commended.
  • @debratav9921
    Very interesting and useful video. Specially thanks for attention to great details, that made me confident to assemble similar DIY kit. Which already bought components but not yet tested.
  • @GENERALWA5TE
    Great video Sorin, with that size box you could use a small solenoid between the spot weld PCB and leads which could break the circuit at the same time as the 2 x H7 bulbs you used.
  • Thank you for sharing your eyeball engineering, great job. Know that the Light of your being is a blessing to everyone on your journey. Shine on
  • @sagarghatti

  • @CTCTraining1
    I do like the way you finish/house your projects especially this time giving everything a bit more space. Do let us know how the battery performs over time.
  • @MichalKottman
    I love the concept of "I can use all my devices as independently rechargeable power sources".
  • @subtext9881
