AC to DC for Welding Machine Output Voltage (Under 10$)
#weldingmachine #ACtoDC #arcwelder
Hello...
In this video, as I promised to many of my viewers, I tried to show how to convert the output voltage from AC to DC in an affordable way for the Arc Welding Machine I made before. Of course, the process I did is not only valid for this machine. You can convert the output voltage of your welding machine with AC output to DC with this method. The materials I use are quite affordable. Total price under $10. For the rectification process, I used 5 bridge diodes of 50 Ampere KPBC5010. By connecting the bridge diodes in parallel, I have increased the current resistance to 250 Amps. You can use 5 bridge diodes in the same way for your 200 Amp welding machines. For higher current welders, the number of diodes needs to be increased. I connected a 4700 microfarad capacitor to the output. In this way, the AC output voltage from 40V has increased to 60 Volts. Of course this voltage will drop during welding, but for the first start of the arc it is better to have a higher voltage.
We can weld materials such as stainless steel by converting our output voltage to DC. In addition, the weld seam is smoother. Besides, you can use your welding machine as a TIG welding machine. Of course, there will be other materials needed for this as well. Maybe we can try that in the future.
I hope you enjoyed my video and my procedures were clear. If there are places that are not understood, you can ask by writing in the comment section of the video.

CONGRATULATIONS. THIS IS THE BEST STICK WELDER PROJECT I HAVE SEEN IN KZhead. EXCELLENT DESIGN, MATERIALS, PARTS, CONSTRUCTION, ASSEMBLING, SHARP AND SAFE. NOTHING TO DO BETTER. I WILL BE WATCHING ALL YOUR PROJECTS.
Thank you so much 👍👍👍👍👍
Very nice and tidy construction! Many years ago my younger son built a TIG welding machine from my father's old Lincoln "tombstone" AC welder. He wanted to be able to weld very thin material, also, and we determined that a large inductor was necessary to stop the arc voltage from dropping to zero. We found no information on the size of the inductor required, except an off-hand comment somewhere that in commercial machines the physical size of the inductor was about the same as the welding transformer. Our scrap stores supplied the requisite transformer, which we re-wound as a choke., using the existing coil wire which we salvaged. With added triac power control this new welder worked very well indeed. Fitted with an arc starter this machine became a very fine TIG machine, too. Adding an arc starter has its own problems. If you wish to know about them, ask me here.
Hello. Firstly, thank you. I am also thinking of using the machine as a tig welding machine. Another follower recommended the idea of using a coil to connect to the output. I'm thinking of doing it by wrapping the cable I used in the secondary winding around a toroid core. But I didn't think of making it too big. If you have detailed information on this subject, your advice will be useful to us. Thank you for your attention 👍
@ Thanks for your interest and willingness to learn! For successful TIG welding, an arc starter is necessary so that the tungsten electrode tip does not get contaminated with welded metal. The successful arc starter system consists of 3 major components: 1) A source of high voltage at high frequency. 2) A coupling transformer. 3) By-pass capacitors. The high voltage is needed to ionize the air between the work and the welding electrode, thus providing a conductive path for the arc to begin without touching the work. We used a 10,000 VAC ignition transformer typically used for oil fired domestic heating furnaces. The high frequency is necessary so that the welder does not get electrocuted by the high voltage. Thus the frequency must be high enough for the high voltage to travel over the skin of the welder/machine operator. To produce this high frequency we used spark gaps in series, using small broken tungsten carbide milling endmills for electrodes. Some high voltage capacitors are also required for this circuit. A coupling transformer is needed to superimpose the high frequency voltage onto the welding current. This design was intuitive/experimental and turned out very well. Basically it consists of 2 concentric coils, the inner primary coil is perhaps two dozen turns of wire in one layer, carrying the the high voltage. The secondary winding is made up of 2 layers of welding cable. We found experimentally that placing a ferrite stick from a radio antenna into the centre of this assembly improved the coupling tremendously. Without this ferrite stick perhaps fewer turns of the primary coil would have been necessary. One leg from this transformer goes to the AC input of the full wave rectifier bridge. This next part is most important if you wish to avoid expensive failures! It is absolutely necessary to bridge each diode in the bridge rectifier with the appropriate by-pass capacitor!!! Failure to do so will cause the immediate destruction of at least 2 of the rectifier diodes. These capacitors are AC duty and were fairly expensive from what I remember. Feel free to contact me should you have any specific questions. Bear in mind that I will have to ask my son to elaborate, and may require the partial disassembly of said equipment. Good luck with your endeavour. I trust the foregoing will assist you in your studies for building this apparatus.
Thank you very much for this long and beautiful explanation. You explained in detail. Thanks again 👍
Gracias Maestro!!!! Me has iluminado,hace tiempo quería modificar una vieja máquina,me alegraste el día!

Absolutely spectacular! I've watched a lot of welder builds and this one is fantastic! I'm building one now as I type this. Thank you. It's perfect.
I thank you too. I am so glad you liked it. Do not forget to use silicon insulated cable on the secondary side. If you have any questions, you can write here.

Good work as always. We shared this video on our homemade tools forum this week 😎
Thank you 👍
Adding diode bridges in parallel is not recommended, because the diodebridge with the lowest voltage drop will take all the current and burn up, while the other bridges will follow one by one. It's better to choose 1 diode bridge with enough current rating, or use 4 separate diodes with enough current rating. Also, when using DC for stick welding, your welding electrode must be connected to the positive terminal, and your alligatorclip to the negative terminal if you are welding thick material, when using very thin material (sheet / plate), your electrode must be connected to the negative.
Hello. Thanks for the information you provided. I thought about the alternatives you mentioned. However, 250A diodes are very expensive.
@ aside from the capacitor you can use a resistor to balance the current in the redtifier bridge so they do not burn.
C’est excellent merci beaucoup pour l’exercice ❤
Merci aussi. Je suis content que ça te plaise 👍

Thank you so much. I'm glad you like it 👍
Fantastic job, fantastic result, thanks for sharing your knowledge, I have an old welding machine but I love messing around with these things, I'll build it for sure, one question, could it be considered an inverter even though it's so basic?
Hola. En primer lugar, gracias. Dado que las máquinas inverter son de corriente continua, podemos decir que el resultado es el mismo. Sin embargo, en las máquinas inverter, el transformador no es así, es decir, no es el mismo sistema.
@I have seen an inverter from the inside and it is indeed not like that, I have read that it depends, I don't know if on the material to be welded or the diameter of the electrode, the polarity could be changed. With this modification, could the same be done with this group?
Just like you said. There is some information on the electrodes. Specifies which pin should be inserted in which polarity. In this case, you can use it in this machine by changing the polarity according to your needs. What is the maximum current value of your welding machine?
@t is to be built I have the material and it will be a replica of the one you have shared with us, the machine I saw inside was not mine

Привет. Google переводчик иногда делает бессмысленные предложения в русских переводах. Но я уверен, что вы написали хороший материал. Спасибо

A perfect way to arrange the bridges, very impressed.
I'm glad you liked it. Thank you very much 👍
Awesome 👍 brilliant learned some thing DC welding
The build is very good. The largest microwave transformers are rated for abs maximum 1800VA x 2 = 3600VA/40V = 90 Amps. This is without considering losses. You may be able to push it to 100 Amps max. based upon duty cycle. However, the secondary wires in the transformer cannot take 100 Amps. They may be perhaps 60 to 80 amps. Unless you use a small duty cycle like the commercially available welders. whatever, it is still able to supply high enough current to weld. Now you must add the wire feed and the cable although you may be able to just do stick welding..
Hello. In this state, 100A can be taken easily. I agree with you about the cable I used in the secondary winding. However, I found it appropriate to do this in order to obtain sufficient voltage with 2 transformers. I've been using it for over 1 year. Since I used silicon insulated copper cable in the secondary, I did not have any problems. The dimmer circuit I used for current adjustment did not fail at all. I will experiment with adding the necessary equipment for tig welding at the first opportunity. Thank you for your attention 👍
Belo trabalho!!!
Obrigado. Fico feliz que goste 👍
Saludos desde Venezuela, gracias por su exelente presentación.
Gracias también. Esta aplicación realmente funcionó muy bien. Sería mejor usar un solo diodo de 200A, pero los diodos de 200A son muy caros. Estos diodos puente cuestan $1 cada uno. Es bastante barato. Saludos desde Turquía 👍
Amazing build quality keep up the great work my friend
Thank you so much. I'm glad you like it 👍
Для более лучшего охлаждения под диодными мостами нужно было промазать теплоотводную пасту, и не сверлить под их алюминиевым корпусом отвертиия для воздушного охлаждения. Лишние отвертия резко уменьшают полезную площать для более эффективного отвода тепла теплоотводом от каждого перегретого алюминиевого корпуса диодного моста. Токоотводные медные жилы хорошо и надёжнее припавивать с предварительной их обкруткой места соприкосновения с контактами мостов и толстых медных проводов более тонким медным проводом на 2-3 оборота (D 0,5 mm) Это нужно для более надёжного пропая припоя, который может в любой момент оторваться от постоянного перегрева, плохого качества пайки и сильного окисления контактов при частой сварки во дворе и под открытым небом. Если при плохой пайке случайно разомкнётся хотя бы один некачественный контакт на любом выводе диодного моста, то другие могут быстро испортиться от перегрева.
Привет. Спасибо. Действительно полезная информация.
Основная проблема не в мостах и их пайке, а в сечении вторичной обмотки и сборных шин . Трансформаторы сгорят гораздо раньше мостов т.к. это место с максимальным тепловым сопротивлением.

@ sizinle nasıl iletişime geçebilirim?
Параллельное подключение диодов без выравнивающих резисторов ( а в диодной сборке их просто не возможно поставить ) приведет к неравномерной нагрузке на диоды в силу их неодинаковых характеристик и к выходу их из строя со временем. Применять следует либо мощные диоды с запасом по току, либо..... - ( было бы интересно ) синхронный выпрямитель на транзисторах.
И снова здравствуйте. Я предпочел этот метод, потому что одиночный мостовой диод с большим током очень дорог. Я согласен с вами в том, что вы сказали. Насчет балансировочного резистора могу сказать следующее... Так как он не выдерживает такой мощности, то приходится использовать очень мощные каменные резисторы. Это снова создает проблемы с точки зрения стоимости и размера. Вот как я это использую. С диодами проблем не было.
@ И... причина: идентичость параметров в пределах одной партии.😎

I admire what you offer on your channel and a follower for two years. I manufactured a crude machine of four transformers. I hope you will help me with how to connect it to a variable resistance to control the voltage in order to raise or lower the ampere coming out of it. I would be grateful if it was a clear and simplified diagram. My appreciation to you, sir❤
Hello. Firstly, thank you. I would be happy to assist you as much as I can. There are 2 schematics in the description section of the welding machine video I made with 2 transformers. One is the general wiring diagram and the other takes the extra triac connection to make the dimmer circuit more powerful. Check out these diagrams and get back to me. I will try to explain how to use a dimmer according to your mains voltage value and total power value.

Ow simple of course but not reliable 😅 ultra-thin heat sink for a power dissipation greater than 200W, no snubbers, nothing to equalize the current between the diode bridges and a capacitor that's actually not needed and that's going to fail very soon because of the huge ripple current

Clever design! Only thing that would worry me is no fuse or trip on box! If say recticfier shorted catistrophic could take out transformer! Fit antisurge/time delay fuse to stop nusence during welding surges! Btw have you any info on welding aluminium as I am not a welder just an electronics nut retired ! Fraser
Hello again. You are right about insurance. To be honest, I did not install an extra fuse in the box because I was using the machine at home and in a socket with a maximum 16A fuse. I will try to make a filter with a coil on the output side. If I get the result I want, I will share it as a video. I haven't tried aluminum. My profession is also electronics. I'm working on circuit design. Whenever I get the chance, I work on something in my workshop and prepare videos.

Thank you very much for the answers! I'm going to make a welding machine out of *4 transformers,* please tell me how to convert it to DC, what capacity capacitor can I use?
Even if you don't use a capacitor. The capacitor works to start the arc more easily by charging to the maximum voltage value of the alternating current, but it is fully charged again only when you pause the welding process, even for a moment, as there is a continuous discharge situation during welding. If you do not use a capacitor, you will still get DC voltage. Of course, it is not full DC, but it becomes a full wave rectified signal and the sour values of the alternating current are destroyed. If you want to use a capacitor, it can be 4700 microfarads 80 or 100V. The voltage value of the capacitor depends on the output voltage you get. For example, when I converted 40V AC voltage to DC, I got 60VDC and I used a 100V Luk capacitor. I hope I was able to explain
Amigo trabaja con 3 puentes de diodos bendiciones amigo excelente explicación.
Gracias. Según la teoría, con 3 diodos puente se obtiene una resistencia de 150A, pero en este caso los diodos están sobrecargados. Por lo tanto, utilicé 5 diodos de puente para una operación cómoda.

Gracias. Las entradas de los transformadores deben conectarse en paralelo. Las salidas están en serie... Da igual el valor de la tensión de red, es decir da igual 110 o 220. La razón de esto es que los transformadores de horno de microondas que se utilizan donde vive se fabrican en consecuencia. Espero poder explicar

Est-ce que trois points de diode KBPC 5010 peut faire le travail ? Car j'ai que trois sous la main Merci beaucoup pour le partage j'ai trop aimé
Bonjour. 3 diodes ne suffisent pas. D'après le calcul, bien que 3 diodes correspondent à 150A, cela reste à la limite. Si vous voulez au moins 4 ou même plus de garantie, je vous recommande d'utiliser 5. Merci pour votre attention 👍

No entiendo exactamente lo que quieres decir en este mensaje. ¿Quieres que use el cable de silicona que envolví alrededor del transformador entre el electrodo y el enchufe?
@ ,Mas bien entre el electrodo y la pinza que es la herramienta que normalmente segura el electrodo, desa manera se puede segurar el electrodo con la mano usando guantes claro! como si fuera un lápiz, como cuando escribes .Gracias por responderme, me dejastes contento , normalmente no me responden, un abrazo. !!(^~^)!!.
Hola, por supuesto, te responderé a ti y a todos cuando tenga la oportunidad. En cuanto al tema que mencionaste... se puede hacer un aparato de este tipo, pero no se puede mantener demasiado cerca debido a las salpicaduras del arco. En este caso, tampoco sería una herramienta muy útil. El calor también es un factor importante. No es muy conveniente considerando estas desventajas.
Otra pregunta profesor usted cambio el adaptador de 12 voltios por un transformador pequeño ?? Por qué motivo y como se hace la conección?? De antemano muchas gracias
Hola de nuevo. La primera fuente de alimentación de 12 V que conecté falló y la reemplacé. Sin embargo, el cambio que mencioné en este video estaba relacionado con los aspectos de los fanáticos. Establecí la dirección de los ventiladores que soplan antes de soplar. ¿Activaste los subtítulos mientras mirabas el video? Si lo viste sin abrir, te recomiendo que lo vuelvas a ver 👍 Pero no dudes en hacer preguntas 👍
I'm sure you can do it, everyone will turn to your channel because it is very educational and makes others smart, your channel will be bustling. Not everyone can afford ACDC Tig Welding because it is very expensive.
Hello. I agree with you about the tig welding machine. I want to buy it too but as you said it is quite expensive. I'm thinking of adding to this machine. Thank you for your attention 👍
@ I hope you can do it, I'm always waiting
Hello. I've got this on my to-do list. I'm trying to organize my workshop a little this time. I'm going to experiment with a gas cylinder and torch head. I think it will, but I don't know when. This row I need some wood related tools. That's why I'm going to work on these for a while. Thank you for your attention 👍
Nice experience
Thanks. I'm glad you like it 👍
Great effort friend. Please can I use winding wire 4mm for the secondary
Thanks. I used 4mm2 silicon insulated copper cable. Honestly, it's a little thin, but I've been using it since I made it and I'm satisfied.
Buenos días, esta exelente el diseño, funciona para los Países con corriente 110v
Hola. Primero, gracias. Funciona de la misma manera en lugares con 110V. Sin embargo, es necesario utilizar cables más gruesos en el lado de entrada. Además, el circuito atenuador utilizado para el ajuste de corriente debería ser más potente. La razón de esto es que la corriente extraída de la entrada es mayor en lugares con un voltaje de 110V.
Maşallah.Harikasin

Salut! J'ai 2 questions je voudrais savoir s'il faut automatiquement 5 diode pont ou bien 1 ou 2 peut suffir pour une tension de 40v et pour le condensateur je utilisé 2 condensateur de 10000uF 63v? merci!
Bonjour. Le nombre de diodes étant lié à la valeur du courant, il est nécessaire d'utiliser 5 ponts de diodes dans ce modèle. Parce que les diodes sont de 50 ampères. Si des diodes résistantes au courant plus élevé sont utilisées, 1 ou 2 suffiront. Cependant, les diodes à haute résistance au courant sont un peu chères. D'autre part, vous pouvez utiliser un condensateur de 10000 microfarads. Cependant, étant donné que la tension dépasse 60 volts après le processus de rectification, le condensateur 63 V Luk peut être endommagé. Mon conseil est d'utiliser un condensateur Luk d'au moins 80V. Merci pour ton intérêt. Si la réponse ne suffit pas, veuillez réécrire.
Thanks this good vid! Just curios, how did you calculate/figure out what size of capacitor to use? Also have you thought about setting a switch to change between ac/dc? Thanks again :)
Hello. I tried to keep the capacitor value as high as possible. However, no matter how high it is, the capacitor effect is lost because the resistance is close to a short circuit during welding. Switch would be fine for AC / DC conversion, but it would be necessary to use a switch or contactor resistant to very high current. Instead, it would make more sense to remove separate sockets from the AC outlet. Honestly if the box size was a little bigger I would do it this way. Thank you for your interest and comment.
@ thanks for the answer. Okey so just the higher the better. But once welding is started the benefit from the capacitor is lost? Its just for the ignition? Oh yes thats a much better ide... I was looking at where to find such powerful switches haha.
When the welding tips are idle, the capacitor is charged to the maximum voltage (60V for my machine), but since the electrode resistance is close to zero during welding, it discharges quickly and does not rise much during the arc. But still the source voltage is not considered AC. because full wave rectification is done with bridge diode. But not exactly in DC...
Good day sir,i would like to know about that you created it is helpfull to us,i am subcriber to your channel,my hobby is making diy...i already started to make 2 mob i wound it awg8 stranded wire,it works,i follow the diagram u post in the link...ill gather the materials needed but not completed yet,lack of budget...i am thankful to you that i learned your project that youve'd shared in youtube.
Hello. I thank you too. I'm glad you liked it. Greetings from Turkey
Very neat. But please, please tell us details of windings. How can I build the same as you, if I don't know how many turns of wire is in your primary and secondary windings??? And what guage of wire you have used?? Erich in New Zealand
Hello. Firstly, thank you. This video was made for the process of converting the output voltage of the machine to DC. I recommend watching the actual video of the welding machine with subtitles. If it is still unclear, I can give you as much detailed information as you want. Greetings from Turkey 👍
Grandioso proyecto y el acabado está inmejorable. Puedes subir algún diagrama de todos los componentes y conexiones hechas?
Hola. Disculpe mi respuesta tardía a su mensaje. Dado que el diagrama es simple en este sistema, lo dibujé durante el video y no hice un diagrama adicional. Los materiales que utilizo son 5 diodos puente KBPC5010 y un capacitor de 4700uF/100V. También traté de dar alguna información con subtítulos en el video. Puede que no lo hayas visto con subtítulos. Muchas gracias por tu interes. Si el esquema en el video no funciona para usted, vuelva a escribir.
Elinize emeğinize sağlık
Çok teşekkür ederim Ahmet bey 👍
Muy ingenioso para tenerlo a muy bajo costo...
Muchas gracias. Me alegro de que te guste.
Murat bey merhaba saygılar nasılsın arkadaşım eline sağlık bana yapılı gönderebilir misin fiyat olarak ne dir
Teşekkürler Necdet bey. Kusura bakmayın lütfen ama satış yapmıyorum. Malzeme toparlama ve yapma için zaman bulmam zor gerçekten. İlginiz için tekrar teşekkür ederim. Selamlar
Good job....
Thank you so much 👍
Murat hocam eline sağlık çok güzel ve faydalı bir paylaşım olmuş uzun zamandır yabancı kaynaklardan araştırma yapıyordum ama senin videon kadar anlaşılır ve faydalı bir içeriğe denk gelmemiştim. Benim bir sorum olacak benim kaynak makina tekntrafolu 250amperlik bir trafo köprü diyotlara bağlantı şeklinde bir değişiklik oluyormu tek trafi yada çift trafoda
Merhaba. Öncelikle çok teşekkür ederim. Köprü diyot bağlantısının trafo sayisi ile ilgisi yoktur. Ancak akım değeri ile ilgisi vardır. Eğer aynı diyotlari kullanmak istiyorsanız en azından 7 adet kullanmanızı tavsiye ederim. Bağlantılar tamamen aynı olacak sadece paralel bağlı diyotlari sayısı artacak. Çünkü sizin makineniz 250A. Umarım yardımcı olabildim. İlginiz için tekrar teşekkür ederim 👍
Sayın Hocam,kaynak makinasının ön yüzündeki pot düğmesi ne işe yarıyor?Akım ayarı içinse oluşumuna açıklama yapabilirmisiniz?(Ben gazaltı kaynak vede TİG kaynak makinasına göz diktim de).Hocam çok özür diliyorum,birinci bölümü seyretmeden bu videonuzu görünce yazdıklarım için.Şimdi sadece ölçüler için açıklamanız var mı ?
Günaydın Agah bey. Ölçüler derken kutu ölçüleri mi yoksa kablo gibi malzemelerin ölçüleri mi? Yorumu doğrultma işlemi videosuna yapmışsınız. Bu nedenle soruyorum
Kya 4700 mrf 70 v llgaskte hai and 1ya 2 pis merepass 2000va trasfarmer hai output 40 v nikalta hai ac kya mebi DC bnaskta hu volt adik krne keliye ........pleas btaye sir
Hello. I couldn't understand what you wrote. It would be better if you translate it into English or Turkish with Google translate.
hello Murat I have built the DC version and it works very well, I only have to get the point of the regulator, I have noticed a detail of easy solution and that is that when unplugging the equipment the capacitor remains charged, with the consequent little scare when releasing the electrode clamp and touch with the other clamp, I have thought that with a porcelain resistance of the ones that the electronic card of the microwave has connected in parallel with a button that closes the circuit once the equipment is unplugged, said capacitor could be discharged, please tell me if it is feasible to use those resistors in this way
Hello. You have made a DC version... I wish you to use it in a healthy way. As for your question... As far as I understand, you are considering a system to discharge the remaining energy in the capacitor after unplugging the device. You're thinking of doing this with a button too. It's possible. You can do this by connecting a 10W stone resistor with a power of around 270 ohms to the output terminals and a button in series. Just hold it down for 1 or 2 seconds. Another method could be as follows. If you connect a 270 ohm resistor to the output terminals by connecting the normally closed ends of this relay in series using a relay fed from a 12V power source used to feed the fans, the relay is de-energized when you pull the plug and automatically connects the output in parallel with the 270 ohm resistor and discharges the capacitor. I hope I was able to explain
perfectly explained because the option of the relay had also been contemplated just as you say, contact of the relay at rest, and effectively when plugging in the equipment the contacts will open and when disconnecting it and returning to its position the resistance circuit is re-established producing the download I suppose that if the resistance is greater than the values that you indicate there would be no problem@
I chose the resistor value according to the output voltage. During discharge, around 60V / 270ohm = 220mA current is drawn. This indicates that the resistor must have a withstand power of 13W (60 x 0.22 = 13W). But 10W will be enough.
thanks for everything, with your videos and the explanations after my consultations it has been very easy to build the team, again thank you very much, a hug@
I thank you too. Rest assured that I will always do my best to help. I wish you healthy days...
Hola Murat! Quiero saber cuál es la función de tantos puentes rectificadores y al conectarlos todos en paralelo al voltaje AC que pretendes con esto? Con uno no es suficiente? Logras aumentar el voltaje con esto?? Por qué el condensador es el que lo aumenta, me parece curioso la cantidad de puentes rectificadores y no entiendo muy bien la función de tantos puentes rectificadores. Vi otro diseño pero el hombre le toca usar 3 TF por qué con 2 no alcanza el voltaje suficiente para soldar en DC yo veo que con tu diseño logras un buen voltaje. Quiero saber con esos dos TF solos sin la ayuda de la electrónica de tu diseño, cuántos voltios logras? También quiero saber de cuantos vatios de potencia son esos transformadores de microondas y el awg cal. del secundario que empleaste en el video. Muchas gracias! Tu info me sería de muuuuucha utilidad, gracias nuevamente
Hola. Este proceso también se puede realizar con un solo puente de diodo y condensador. Sin embargo, en este caso, es necesario utilizar un diodo resistente a por lo menos 200 amperios. Los diodos puente de 200A son muy caros. Usé 5 de los que dijeron que costaban alrededor de 1 dólar cada uno. 50A cada uno. Traté de obtener un diodo puente con una resistencia de 250A conectándolo en paralelo... este sistema no aumenta el voltaje. Entonces, ¿por qué el voltaje pasa de 42 V CA a 60 V CC? Este es un tema simple en electrónica, pero puede ser difícil para las personas que no entienden de electrónica... Sin embargo, permítanme hablar un poco... el voltaje alterno ocurre en la salida del transformador. este voltaje tiene una señal sinusoidal. es decir, en forma de una curva sinusoidal. la curva sinusoidal con alternancia positiva y negativa (alternancia = cada media onda de la curva sinusoidal) se convierte solo en alternancia positiva después del diodo puente. Sin embargo, en este caso todavía hay tensión alterna y de hecho se obtiene un valor de tensión inferior a 42V. Sin embargo, cuando se inserta el capacitor, se carga al valor máximo de cada curva sinusoidal (más alternancia). En otras palabras, cualquier valor de voltaje que llegue a los terminales del capacitor se carga a este valor. Este valor es el valor de 60V. Encontramos esto matemáticamente como 42/0.707=60V. Así es como es... Espero haberlo explicado. Por otro lado, cada uno de los transformadores que uso ronda los 900W. El cable que utilizo en el lado secundario es un cable de cobre con aislamiento de silicona y una sección transversal de 4 mm2. Cada transformador tiene 24 devanados. Dado que la sección transversal del cable es delgada, hay calentamiento. Es necesario utilizar un cable aislado con silicona para que este calentamiento no dañe el bobinado.
Excelente
Muito obrigado 👍
Thanks 👍
Thank you too 👍
I like your work; will it work without the dimmer circuit. and does it matter if it's 110 or 220 here it's more like 120 and 240 ??
Hello. It works without a dimmer, but always at maximum power. Since you will use a microwave oven transformer produced according to where you live, the mains voltage value does not matter. 110, 220, 240 it doesn't matter... Thanks for your interest...
@ Thank you for the reply, I have built many power supplies through the years and your design is the best-looking DIY welder I have seen on here, going to Build it Thanks again
Thank you too. Good luck
Elinize emeğinize sağlık. Üstadım merhabalar.. pil punta makinesini aynı trafo mantığı ile yapmak hedefindeyim. Ac ada dc olmasının kararlılık veya kalite açısından farklılığı olurmu.. açıkçası dc ile çalışmak sanki daha kararlı ve net sonuçları sağlıyor gibi bi mantığım var.
Merhaba. Ben de sizin gibi düşünüyorum. DC ile daha iyi olacaktır. Ancak akım ark kaynak makinesine göre çok daha fazla olacağı için kullanacağınız köprü diyot 1000A falan olmalı. Oldukça pahalı olacaktır. Ayrıca kondansatörü büyük değerli koyarsanız her puntoda çok fazla ark oluşur. Doğrusu bunların hepsini hesaba katınca AC kullanmak mantıklı oluyor
