Congrats! you are super young :) and still this project is done on a "pro" DIY way. I like that the background of physics is also understood and you talk about safety issues too. Well done!
Very neat job, Max, I have seen many videos on the subject, but you have explained it clearly and taken the time to make it look neat and tidy. Great result 👍👍
@@GrandadIsAnOldMan Thanks, James 😃 Yeah, it's such a relief that TH-cam finally did something about it, and that I can finally stay in touch with the viewers again. 😊 Have a good weekend!
The spot welder is very useful and the video is well explained . I sure wanna build one spot welder btw video was very helpful and as always Amazing 🔥🔥❤
Hi, thanks for your comment. Yes I do believe that's true although those amps won't really take any negative effect on you unless there's a sizeable amount of voltage, like at around 30-50Vac is where it may start to get lethal with enough current. This is what a US electrical once said. Cheers, Max
Plus, anyone using this machine will most likely always be safe as its chassis is linked to earth ground, creating an easier path for hot wire current to flow through rather than a person, as a person has a much higher resistance that the grounded shortcut path.
Thank you and good luck with building yours'! Also stay tuned for the upcoming TH-cam video where this spotwelder will be used in building a battery 🔋 ☺
Hello. I want to note that there are traces of burning the tape, which means overheating of the battery. And 1 more transformer is not enough to weld ribbons more than 0.1 mm. So, you need at least 2 transformers. To create a full-fledged apparatus, it is cheaper to buy an old transformer-type welding machine and rewind the winding.I mean, a welding machine for welding with electrodes
Hello there, thanks for your comment. You are wrong on the first point you stated, the batteries did not overheat nor did they get hot. On your second point, you make more sense, the transmormer is in fact not powerful enough on its own to create clean and long lasting welds. This after all is a DIY project, living it up to the same standards as factory-made devices would be costly and hard to replicate.
I’m not being mean just got a good laugh about the square bar of wood again not mean I’ve heard boards called lots of things but that was a first and I promise I’m using it on job sites from now on
CAUTION sorry but one big safety thing.. wires that leads to pedal has unprotected male connectors on welders side of circuit so if that connector accindentally unfastens there is exposed live wire that could be accindentally touched..
Nice work. The way you;re sweating, on the intro, looks like you were slaving over a hot stove ;-) Or did you just steal your mother's microwave transformer. ;-)
Thanks for watching! Well, it was getting quite hot inside with my mom's microwave running, so I found the solution by pinching the transformer for something... better 👈😉 Cheers, Max
Hey Max, me again. Loving the circuit diagram at 7m48s - simple and detailed. At this point I realise your input is a USA 110V AC power supply. I wanted to ask your advice for doing the project for a UK 240V AC supply - my head's not in the right place for doing the maths today😄. Your transformer has 100 turns on the primary and 2 turns secondary - for a UK power supply, the input voltage is effectively doubled, what (if any) changes do I need to make to that secondary coil? Obviously I'll be using a transformer salvaged from a UK 240V microwave, so I'm assuming I can just do the same 2 turns - but I'm second guessing myself. Is this initial assumption correct?
Hi, Michael. Thanks for your comment. The number of turns on your primary winding for a UK 240 mains power supply should be around 220 and the same 2 turns on the secondary (low voltage output). Cheers, Max
I think that is due to the tips being from copper. Would you recommend the right metal my fuse should be made out of or where would I get those? Thanks.
Nice video Max! Although I wanted to point out your lethal error at the beginning of the video where you point out that the transformer produces a "lethal voltage in their original state but we will be rewinding this secondary coil to produce a really low voltage .. high amount of current" What you have actually done is take a (relatively) safe high voltage transformer and produced a deadly high amp transformer! It is not the voltage that is lethal to the human body, but current (amps)! Of course, V=IR means that they are related, but if you think of electricity as a river then you get the idea pretty quickly. Imagine voltage being the flow of the water in the river and the amperage as the volume of water. You could have a very fast high voltage stream that poses little threat to an adult, whilst a virtually static but a deep slow moving, even static river that could drown you.
Hi Michael. Thanks for your consideration. However, I hate to break it to you, but you must've understood it back to front... Any high voltage especially in the thousands of volts with the tiniest bit of current in the tens of miliamps range is enough to kill a person. With high current flow and almost no Electric pressure (volts) such a 2V, it won't even hurt an insect! Think of voltage as electric potential, if there's little to no potential (using height metaphorically in this example) a heavy human who jumps off of a 2ft ledge won't hurt themselves as much as if they were to jump off a lethal 200ft cliff even weighing less. Think about that. Voltage and current work in respect to each other making amplitude in voltage the main characteristic for electric shock, and current being the amplifier of that shock. I hope this makes sense. - Max
Final thought - a typical police taser weapon for incapacitating suspects, is 50,000 volts. But the current is extremely low. Food for thought. Sorry to bang my little drum so loudly - it's my autism at work, honest! - but safety is important (can't fault you on your safety, btw, but the viewers may not be so considerate of theirs).

I'm so glad to hear that! Thanks a lot, ksp! Have a good weekend :D
Very useful project and nicely explained 👍👍🔥🔥
Thank you! Cheers!
Max As a UK electrician once told me its the AMPS (even at low voltage) that WILL kill you as much as volts, That said its a good build

I thought that's how they're called tho 🤔
Glad I could give someone a laugh! 😂
@@MaxImagination I didn’t mean any hard feelings I enjoyed your video and had a chuckle please keep making the great content
@@joeymcclaflin5172 No worries... thanks a lot! 🙂
Great idea 👷👍
Thank you! Cheers!
Can you please make another remote control car video?(homemade) Like your vids :D
Will do, one day ☺
Thanks! 👍
@@MaxImagination Thanks, hopefully in the next video! :]
C’est excellent merci beaucoup pour l’exercice ❤
Thank you!
I ripped all that stuff out the microwave so I should be good
good learn
CAUTION sorry but one big safety thing.. wires that leads to pedal has unprotected male connectors on welders side of circuit so if that connector accindentally unfastens there is exposed live wire that could be accindentally touched..
Thanks for pointing this out! You definitely have a point here. I'll fix that! Thanks.
Cool stuff 👍
Nice video
Thanks, Kristoffer!
Bravo, bravo, tnx. super abs. best video, work and product and abs. respectful from old BG.
Glad you enjoyed it! Thank you!
Wow! It' Is Amazing 👏 😍

you left the metal chokes in? ok? Does that make this build safer?
The way the transformer is configured is correct, it's safe on the output side and gives you the power to made decent welds.

Very good 👌
Thank you! Cheers!
whats the white strip? I must have been watching ElectroBoom and thought I replied on his video?
What white strip?
Why not fuse the live wire?
Good point... I forgot I left that out! Will consider adding one.
Wow Superrrrrrr bro
Thanks!
I have 8 gauge wire, should I just do like 5 or 6 turns to be sure? lol?
8 gauge wire might be too thin. The wire could get hot. In terms of windings, they should be the same to give you a low voltage output. 2-4 turns.
I wish I could build this
You've got this! 🙌
I’m too little 😂
@maximagination, is there any difference if the copper tips were closer?
Not much of a difference, as long as there's a 1mm+ gap in between. It can all depend on the width of the nickel strips you're welding.
Cheers,
Max
Your welds on the fuse are cold welded. Do some checking please.
I think that is due to the tips being from copper. Would you recommend the right metal my fuse should be made out of or where would I get those? Thanks.
Hey you're the best *& Fast 👍 T V M vetrano from Belgium
Thanks for watching ✌🏻
think its 15 amp so how many should I use?
You need 0-4 gauge wire which can handle hundreds of amps of current. The voltage output should be very low. How many of what are you referring to?
Half the audio is missing
Waaa👏

By the way, looking at my demonstration, I was actually grounded while touching the pins, and didn't get a tingle let alone a jolt from the device.
