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.

@ sen bu trafolari sarmak icin hangi kabloyu kullandin benim kullandigim kablolar isinip eriyyor sonra dumanlar cikiyo bi yardimci ol markasi falan nedir soyleyiver

Hüseyin bey. Eski bir mesaja cevap yazdığınız için görememiş olmalıyım.. Kullanılması gereken kablo silikon izoleli bakır kablo. Normal PVC izolatör ısıya dayanıklı değil. Ben yaptığımdan beri kullanıyorum. Hiç sorun olmadı. Kablolar ilk günkü gibi

[@BasementEngineer]

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 👍

[@BasementEngineer]

@ 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 👍

[@المستحيلممكن-ي4ش]

​@@BasementEngineerIs there another solution, because the high voltage capacitors, which are connected to each diode in parallel, are not available in my country?

[@BasementEngineer]

​I'm afraid I know of no alternative for those by-pass capacitors. Perhaps you can contact a repair facility for welding machines, and they may have some used capacitors from scrapped machines. Good luck!

@ Well my friend, from now on I have subscribed to your channel and is calling to follow your videos and more creativity

[@johnconrad5487]

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 👍

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.

[@tony001212]

@ aside from the capacitor you can use a resistor to balance the current in the redtifier bridge so they do not burn.

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.

[@javierdesantosjimenez1873]

@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?

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.

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.

Is it possible to convert alternating current to direct current through a diode that can handle a high current (half wave)?

Hello. Of course it is possible. For example, rectifiers in power plants are made in the same way. Moreover, since I use a bridge rectifier here, full wave rectification is made, not half wave. However, I must say that the capacitor cannot have much effect in this system. Because the current that is fully DC rectified when idle returns to full wave rectified during welding. In other words, it is possible to see both alternations of the sinus signal in the plus, not the straight line.

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.

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.

@ saludos amigo, por favor cual es el rango mínimo y máximo de amperaje de esta máquina soldadura.

[@robertoolguin3016]

buenoas dias, no se mucho de electronica, pero podrias decir que triac usas?

Hola. El triac que estoy usando es BT137. Estoy pensando en publicar un video en un futuro cercano haciendo que el circuito aquí sea más comprensible y ordenado. Construiré el circuito en la PCB y compartiré el esquema completo.

[@veyseltokmak1296]

Murat bey öncelikle elinize sağlık şebekeden çekilen Akım nekadar ben giriş akımını hesapladığımda 30A civarı birşey geliyor bu çok fazla değilmi

Merhaba. 30A olması için 220x30=6600W olması gerekir. Ben evde 10A sigorta bulunan prize taktigimda ara sıra sigorta atıyor. 16A sigorta bulunan prizde kullandığım zaman ise sigorta atma sorunu olmuyor. Ben ölçmedim ama 12A falan akım çeker diye düşünüyorum. Çünkü kullanılan trafolar maksimum 1100W civarında. Toplamda 2200W olur. Bu durumda 10A hesaplanır.

Bản chuyển điện DC này tôi thấy khá hay đó, nhìn cách bạn hàn thì hồ quang khá đều không bị ngắt, bạn làm rất tốt 👍. Có điều tôi băn khoan nếu sử dụng lâu, biến áp, cầu diot có vần đề gì không? Tôi đã có máy hàn điện tử nhưng vẫn muốn ráp 1 bộ như bạn, nhưng có vẻ giá mua linh kiện bằng 1 chiếc máy điện tử giá rẻ.

Như bạn nói, giá thành có thể tương đương với giá máy rẻ. Tôi thường sử dụng các tài liệu tôi thu thập xung quanh. Tôi chỉ trả quá nhiều cho cáp. Cáp được coi là rẻ ở Thổ Nhĩ Kỳ so với hầu hết các nước. Tôi đã mua tình nhân của anh ấy với giá 1 đô la. Do đó, nếu bạn không có sẵn một số tài liệu và bạn đã có máy thì không cần phải làm.

[@nguyenhai7853]

@ thanks 🙂 cảm ơn bạn đã chia sẻ.

diodes paralleled the current goes mostly through the same ones as it heats up I've heard it doesn't add linearly. for example 2 6 amp diode bridges failed where 1 12 amp diode bridge was way more stable

What you've heard about it is true... But it didn't cause much trouble here. That way it's been very affordable and hasn't broken down since the day I made it. It would be very expensive if I used one 200A diode

[@RamirezriojasRamirezriojas]

maestro buenos dias por que queda cargado el capacitor cuando lo apago y que puedo hacer para q eso no suceda

Hola. Dado que la capacidad del condensador es un poco alta, permanece cargado cuando se apaga. Puede desactivar el condensador si lo desea. Aún así la salida será DC. Sin embargo, cuando se mide el voltaje, es inferior a 60 V. En realidad, esto no es un gran problema. O puedes conectar una resistencia en paralelo con el condensador. Sería adecuada una resistencia con un valor de 6,8k y una potencia de 2W. Todavía no se descargará muy rápido, pero no durará mucho.

[@MarioRamirez-t5x]

maestro bns dias dsde peru que pasa si le pongo mas puentes rectificadores de 50 amperios maestro buenos dias al dimmer de 4000 watts le puedo poner dos triacs bta 41600b seria mejor

Hola. Pido disculpas por regresar tarde. Si usa más diodos, el calor por diodo será menor. Eso estaría mejor. Los triacs que mencionaste también serían adecuados para atenuadores.

[@ertanyilmaz9454]

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 👍

[@ProMagomed]

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

Una pregunta y cuáles la ventaja de Aser esta modificado no lo tengo muy claro

Hola. Hay muchas ventajas de soldar con voltaje de CC. Si lo desea, puede encontrar el estado de comparación de las máquinas de soldadura de CA y CC en Internet.

[@52918767]

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 👍

[@RICALRONICS]

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.

[@luisfernandovasquez5438]

Tengo 6 diodos mb358 son de 35 A cada uno, en total serian 210 A, con eso es suficiente? Los transformadores son dos y los enbobine con cable calibre 10, me da un voltaje de 37 v, espero tu respuesta, me gustan mucho tus videos 👍🏻

Hola. Creo que eso sería suficiente. Supongo que la corriente de salida estará entre 100 y 120 A. En este caso, creo que sería suficiente. Sin embargo, el cable debe estar aislado con silicona, es decir, resistente al calor. Gracias por su atención 👍

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 👍

[@FlorinTanasa]

Good job man, I wrote an comment but disappear because youtube consider I put a link. Also you can add thermal protection for diodes bridges (some like this exist on office thermal laminating machine) if you search on internet you found something for open connection at 130 degree Celsius, with manual reset and 16A current nominal.

[@FlorinTanasa]

Some like ar33-130-05-w1-s3 maybe work and youtube leave my comment.

These ideas are very nice but come to mind later. I can add, and I hope other viewers reading these comments will also benefit from the ideas. Thank you so much

Buenos como puedo aumentar el voltaje ⚡ de salida de un equipo de soldadura inverter

Hola. Para aumentar el voltaje de salida de las máquinas de soldadura inverter, es necesario realizar operaciones en el circuito interior. Desafortunadamente, este proceso no es simple y puede ser peligroso. ¿Por qué quieres aumentar el voltaje? ¿Cuántos voltios de salida?

[@djeziatakpa7193]

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 👍

[@necrophalus666]

Hello my friend, Hello from FRANCE ! ;) Please, I have a question : You have a voltage of 40 Volts AC...does this modification (AC to DC) work with a voltage of 54 Volts AC? I made the same welding machine but with slightly larger transformers, so I was able to make more turns with the electrical wire. I get a voltage of 54 volts AC. 5 x KPBC5010 is it sufficient ? or should I add some? Thank you very much for your answer

Hello. Kbpc5010 diode can be used up to 1000V. You will get a voltage above 70V as DC value. No problem. However, since the voltage value is a bit high, it may disturb you a bit when you hold both probes. In other words, you may get an electric shock. On the other hand, it would be good if the capacitor you will use is 100V. But it is okay if you do not put it on.
