Sorry for your arthritis. I know people having that and they take medication, and it works. My guitar teacher suffered about this. Thanks for your comment, glad you like it.

Thank's for the speedy reply Alexander. Yep I take my prescribed medication but it do'es not make my joints any better, just dulls the pain. At nearly 72 it dulls my head as well. You will understand why the powers that be advise not operate machinery when taking pain killing medication. I still enjoy my electronics and Ham radio as a hobby. All the best from John -G0WXU.

I sympathize with what you say. One of the most important things is the love of things, the interest we have for others and what surrounds us. Electronic, radio, hand made, the magic of tricks, and when it's works. RU-vid became a source of nice share and it's nice to meet us about made. Thanks and keep your enthousiasm!

il vous en prie. Disons que cette vidéo permet de construire un appareil dont le réglage de puissance est possible grâce à un triac, composant classique adapté pour fonctionner sur un transformateur, c'est ce qui la rend sympathique je pense. Merci pour votre commentaire.

Chatting is sometime usefull, and sometimes worthless. But lot's of people doesn't like silence and only tool's noise. Anyway, all is clear in this video, and there is an explicative video for the schematic in the video. And one thousand people complaining wich it's not a full tutorial video. I feel posting video on YT is very exhausting. Thanks for your comment, have a great day.

You're welcome. Thanks for your nice comment.

just keep a high degree of engineering for not to replicate it.

Hello, sir, your opinion is useless and inappropriate. You intend to do this, build is not for the engineers, and if you were a high technician or one of them, you would not say what you say. Yes, you are right, there is a foucault current by the screw on the metal core. But your knowledge is to to much simple. These transformers have a high idle current. Their core is welded, providing a high idle current, consuming a high current in idle (no load) mode. These features of the transformer give high power for a smaller size, increasing the high saturated offset of the core and interacting with the primary coil with more power linearity. This is a "over saturated core". If this principle were not affected, the microwave oven would be heavier. A 2KW microwave transformer would weigh 6 kilograms. If these screws made a loss, it will be a ridiculous loss in front of all the magentic field resulting of the high offset saturated core. And now, read this: The E and I of this transformer are welded by the extreme points. It avoids the foucault current because the center of the transformer (the center of the E) is not welded to the center of the I. The screws are at the back of the E. Significantly, these screws make electrical contact between certain points and electrical, they have made a point between the SAMES POTENTIALS POINTS. The error would be to place the screw at the center of the E, in the middle of the I. So the current foucault of which you are afraid does not exist. the main loss of this made are in the low section wire cable, the lead free solder in the terminal connexion, and the joule effect on the screws terminals. But strangely, you noticed no one of this. If you have something to teach us about transformer, tell me. Thanks

Well, for some of you that is. I'm still in the learning stages.

thanks for your great comment.

thanks for your comment ;)

lol thanks for your comment

the refreshing teaching is here ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-MUId45iUrO8.html

@edgeeffect thanks for kind comment. My channel is about general, talking about different subject. Of course, it may interest people interested with electronic in general. Glad you like it.

thanks, glad you like it.

It seems you like it, I am glad of it. Thanks

You can use normal transformer, with separate coil, as a Micro wave oven. The fact with micro wave transformer is than they have very high idle, equalising a more weight heavy transformer. So, you can use 400W ballast from high or low pressure bulb. But a more power is not ok cause it create a short circuit, unless if you add wires on the primary (if there is place you can). So wait a little bit, you will find a new transformer, and be carrefull this time! thanks for your comment.

yes it would have been a nice thing to juxtapose the pratical use and the reason why I maked this. But this reason is passed, and this build is to prevent another case. The reason, wich not specified was to repair a dimmer fan on a Mercedes car. This dimmer was a simple power resistor, wich contain a blown thermofuse, soldered by point. This fuse was not solderable by tin, cause it destruct it immediately. Only quick soldering point was possible. Because I had short time, I used 12V battery and pin punch to weld it. It was dangerous and umcomfortable. After returning the car in time, I decided to build the real device for this kind of task. Now you know! Thanks for your comment.

Oh, you can use brass crimps for that.

no place, as I remember, and short leads dont permit that. there was copper ligature possibilities but customer didn't want.

Thank you for your comment.

thanks for your comment.

glad you like it, thanks for your comment

look for a busted microwave!

thanks for

can you explain to me what do you mean by " old school tooling"? I guess this is an expression, translator cant translate it in the sens of the popular expression.

Old school tooling is hand tools, and knowledge you came by honestly over time. Tried and true crafting. It is a compliment. I enjoyed watching you work.

thanks, I asked you cause this expression appeared several time in the comment. Glad you like it, have a nice day.

LoL thanks for your comment.

hi glad you like it. thanks for your comment.

I'm a X-men, I don't need all that protection.

That is... As I explained it further, there are 3 volts at these terminals. 3 volts, applied to fingers, delivered not more some microamps, and there is no danger to use it. Because you need to have volts to have amps trough the fingers for to see it becoming dangerous. For to have some danger, you need to be present on 100 volts. All voltage under this value is not dangerous, or not dangerous at all. Amps are not the value you need to consider, first you need to consider voltage, and calculating current providing from it trough a load, in this case the resistace of your finger. Of course, you need to consider the internal equivalent resistance from the generator, because if she's high, you will loose lot's of voltage when touching it, decreasing voltage , and cause decreased current, so low risk. Thanks for your comment.

@Russ Pressley thank for suscribe to this channel.

thanks for your comment. I hope you a nice build.

Your welcome Alexander. Thank you! I will post it when it's build.

Eager to see your work.

Daves Tech thanks. Dont Forget this welder was builded in 5 hours chrono. It' a tiny welder, so a hand will incresase it. Thanks for your comment.

Hello, glad you like it. My channel talk about general electronic purpose. Not specially soldering. Thanks for your comment.

glad you like it. Thank you for your comment.

Make your laces is more difficult than make this spot welder. The only difference is you make your laces in few secondes, but you need 5 hours to make this spot welder. The most difficult thing is to find all the components. This way is easy for me because I am a process engineer. I think you would try to make this spot welder, it will give you more confiance on you. Have a great day.

you seems to be very inspired by this video.

Even better, crimp the terminals. If you don't have specialized crimping tool, use vice.

You can sometimes build tools with recycled parts, but in this case, it's a combinaison of electronic, copper, wire, coming from lot's of directions. Glad you appreciate it, thanks for your comment.

ok lol thanks for

Glad you like it, thanks for your comment.

lol !!

thanks man

oui on peut dire ça comme ça, merci pour votre commentaire!

steampunk style...Thanks

glad you love it :) Thanks for your comment.

@Ahmed Ali Didi saha, content que ça te plaise!

je t'en prie merci d'avoir apprécié.

s1monster Je ne m'ennuie jamais, effectivement. Si ce ne sont pas mes mains qui sont occupées je refais le monde, dès que je bricole mes mains sont en adéquation avec mon esprit. Je fais aussi un peu de cinéma, d'écriture et de guitare. Je ne sais pas réellement si je suis quelqu'un qui s'occupe ou si je suis quelqu'un qui a peur de s'ennuyer. Merci pour votre commentaire.

merci merci merci

thanks sir

yes it's work well. Thanks

thanks for you comment, glad you like it.

thanks

thanks for

this is for occasional use. If it was for professionnal use I would make a handle like you said. Thanks for your comment.

very easy to do, and so usefull, don't forget the schematic on the desctription. Thanks for your comment.

yes you're right. Thanks for loving the video and for your comment.

glad you like it sir

Why not... Thanks for your comment!

i have seen spot welders sold that are HUGE and don't have the capabilities this one has.

so you're right thanks!

ok thank you

that's ok don't forget the schematic under the video, and the precious subbers.

lol ok thanks for

thanks for

thank you sir. glad you enjoy it.

ya pas de quoi. merci pour ton commentaire

d'accord..

Yes, only if you weld more than 2 points per minutes. No risk of electrical electrisation. Thanks for your comment.

thanks for your com

yes you're totally right.Because components, woods and other stuff are very old, except the electronic parts. Thanks for your comment.

ok thanks

yes you're right. And like you said it does't matter, it works great and that's all. Glad you like the video, thanks for your comment!

glad you like it

thanks for your comment :)

glad you like it

glad you like it.

thanks

thanks for your comment.

Bsahtek, le cuivre se travaille bien, conduit bien l'électricité, et est beau à voir. C'est un matériau noble. Le "vieux bois" comme celui dans la vidéo donne un aspect très rétro à l'ensemble, relevé par l'affichage bleu. Un beau mélange de technologies de dates diverses, qui ramène à la vie les vieux procédés et initie les derniers modules. Merci pour ton commentaire.

you mean in the description?

Sorry, yes I did mean in the description :)

Good initiative ! Don't forget the schematic with the link on the description below.

mikeyboy2154 je t'en prie merci pour ton commentaire

thanks man

Glad you like it, thanks for your comment.

YES I AM!! thanks to my mom Thanks for you comment, glad you like my made.

hello, yes you're absolutely right. Anyway, the thin layer of varnish is in perfect condition. And the output copper cable (wich made the secondary) is a very high quality souple, ingnifuged coated wire. All these components, in very good condition, make the whole very safe. But yes, of course, there is a " RDC protection" beyond the system. Thanks for watching and thanks for your device, thanks for your comment.

thanks for

thanks you

Hi sir. For your question, your ballast is used to reduce current when the HID is glowing. So, for you can use it, you need to add more turns to the primary of the transformer (the ballast). I sincerely recomand to you to use a simple micro wave transformer. It's not worth to modify a ballast for use it like a spot welder. If you connect the coil of your ballast, it wil make a short circuit, cause lot's of current going trough it. Anyway, you can use 250 watts ballast for it, but not 1500 watts ballast (only if you add wire on the primary coil). Thanks for your comment, have a nice day.

Alexander Hartdegen ok i understand thanks again.

glad you like it thanks

thanks for your comment.

great you like it

glad you like it sir.

That's not to have a crimper!

Thanks

thank you sir.

Yes it was very surprising and very noisy! Thanks for your comment.

WIZARDWERX oui c'est une bonne idée!

I didn't invent it but thank you

I like your comment. Thanks for your comment.

thanks you siiiiirrrrr for your comment.

glad you like it. Thanks for your comment.

nothing! Thanks for your comment.

Thanks for your comment.

Yes it's easy to filed it to have a fresh surface, but you can just clean it with "special electric contact" bomb. You can filed it without damage it, anyway electrodes are easily changeable, filed, or cleaned. The most quick way is to use fine sand paper. Thank for your comment :)

yes that's a nice idea for repeated works. This one is for casual and varied work. Thanks for your comment.

I hve never seen a washing machine with a clutch. mine has got only a belt on one side fixed to the motor on the other side to the drum.

Hello I have the pseudoname of the time traveller. It's a nice movie and I like it. Thanks for your comment.
