Resistance spot welding (RSW) is a process in which contacting metal surfaces are joined by the heat obtained from resistance to electric current.
Work-pieces are held together under pressure exerted by electrodes. Typically the sheets are in the 0.5 to 3 mm (0.020 to 0.118 in) thickness range. The process uses two shaped copper alloy electrodes to concentrate welding current into a small "spot" and to simultaneously clamp the sheets together. Forcing a large current through the spot will melt the metal and form the weld. The attractive feature of spot welding is that a lot of energy can be delivered to the spot in a very short time (approximately 10-100 milliseconds). That permits the welding to occur without excessive heating of the remainder of the sheet.
The amount of heat (energy) delivered to the spot is determined by the resistance between the electrodes and the magnitude and duration of the current. The amount of energy is chosen to match the sheet's material properties, its thickness, and type of electrodes. Applying too little energy will not melt the metal or will make a poor weld. Applying too much energy will melt too much metal, eject molten material, and make a hole rather than a weld. Another feature of spot welding is that the energy delivered to the spot can be controlled to produce reliable welds.
Was inspired to make a much simpler unit by using the on/off light switch, it's wiring and cooling fan from an old food dehydrator ! House the transformer by fribicates a perforated outer steel shell from a cooling fan for better ventilation !
Using the battery post connectorsis a great idea for easy replacement of worn out brass tips !
A great educational video, thanks 😊
This is one if not the best video on how to make a welder I'm going to make a welder using alot of other people's videos but yours is one of the most helpfulPS. When I do make the welder im going to name it THE AMALGAMATE! if you get that reference ten nerd points to you!!!
Мне очень понравилось это видео , все досконально показано в нем . Автору спасибо за столь полный обзор самодельного аппарата для точечной сварки . 😊👍
Спасибо, Никита!
SUPER
Very good. A vid that showed the function and aspects before the how to make. Thumb up for that.
Nice work! Thanks. Battery connectors as electrode holders is pure genius.
Thank you!
using car battery terminals was a really smart idea! congratulations, nice make.
Thanks
Πολύ καλή κατασκευή ! Φανταστικό βίντεο ! Μπράβο!!!
Σας ευχαριστούμε!
very good with the foot control. thanks for sharing
Давно уже хотел себе такую вещь. Просто и понятно.Спасибо!
Пожалуйста!
The cable that connects the arm with the pedal can be a bicycle brake steel cable, it is more flexible and more resistant, in addition you can adjust the distance with a screw.
Excellent work, greetings from Argentina
very nice work
Wooo un excelente trabajo, me dejaste asombrado, el mejor diseño que por ahora e visto.gracias por el video. ( lo intentaré hacer) me gustó mucho tú diseño. 👍👍👍
Nice. The cables colors are not respected but it works and that is the main thing.
Outstanding work, if I can make a suggestion, try not to use too much heat, is the compression rate that does the welding, the heat is just to soften the iron a bit, ideally the weld must end gold with no ash residue, it it burns past that it may break or fall loose in time. I worked on that type of machine for too many years to figure that out. The heat applied to the iron shouldn't be seen, sparks means the iron is either false contact or getting too hot, find the balance of pressure and heat, lean more on pressure.
quite baik dan sangat simpel dibuat dengan sperpat mudah didapat dan dikerjakan
Like this welder and hope to make one, one comment I would like to make, I believe the circuit diagram shows the middle button as being for the hand switch and the bottom button being for the foot switch on your model its the other way round.
Complimenti, ottima realizzazione. E' simile a quella che ho costruito, ma hai avuto la geniale idea di aggiungere il variatore di intensità, al quale non avevo pensato, ma che può risultare molto utile in determinate circostanze!
Un saluto dalla Sicilia, Italia
Very clever mate - excellent project! The only comment I would make is that I believe it would be better to screw the microswitch to the frame rather than nail it because microswitches can be short lived, in my experience - however, just a very, very minor comment. Great work. Cheers
Thanks mate!
Cooling fans only work well if there's a big hole to allow the hot air to leave the box. The small hole you've left where the cables leave at the front of the case needs to be enlarged so that the fan can move a large volume of air over the transformer to cool it properly, otherwise it will overheat if you're doing a lot of spotting. Otherwise, a nice design.
That was a lot of work you put into building that. Very nice, thanks for sharing.
Complimenti bel progetto! E' molto simile a quello che ho costruito io in questi giorni, ma con soluzioni inedite!
Well, as long as it don't cost more than $160 like a harbor freight model does, that seems great, I like this idea.
Using the battery terminals was a great idea..
Gracias por su video Sr más que excelente, saludos cordiales desde Chaco Argentina
Great videos. I've learned a lot from watching DIY Thanks
good job bro.
Thanks!
Very nice thanks
Muy buena hidea y serbisial
NICE WORK
Que trabajo excelente. El circuito me vuelve loco, me cuesta entenderlo jajaja. Pero felicitaciones estimado, esta muy, muy bueno. Abrazo cordial.
Gracias. Circuitería se puede ver aquí - drive.google.com/open?id=0B1O1fbFGJYSac0NzMUdwR1M0S2M
i like the car bat terminals
going to use this part of the build
I don't think I have ever seen a vacuum cleaner with a "volume control" - do you think could I just use a normal 120v dimmer switch, like for lights? Fantastic video, thanks!
Nice vid but you should ground the transformer and fan metal net for safety
I give you a 10+ .Great work!!!
Thanks!
Great job, thank you
muy bueno que proligidad felicitaciones saludos desde argentina juan carlos antoniale
Great job would love to get the schematic as it was difficult to tell what was connected to what.
Trabalho maravilhoso. Parabéns
Ok, quick question, with removable electrodes and foot control, could I use the electrode arms loose for more difficult welding such as inside and under a animal cage to repair damage cage wire?
Top parabéns ótimo conteúdo
Wow I like your table saw setup ; ) looks like I got enuf junk to make a kickarse spot welder :D
saludo. muy bueno de Venezuela
👍
Seriously amazing. Thank you.

Felicidades! Gracias por compartir tendras la lista de componentes? Gracias
Question : How long can i use this spot welder continously ? is it getting hot after 10 minute of using ? please help.
Bonito trabajo, muy elaborada
Gracias
I built one using a car battery but the only battery I have is like 600CC Amps. LOL it blows holes in the batteries I'm trying to us them on. E-Bike Battery 18650 type. I built one like yours using a MOT but need to tame it down. BanGGood sells all sorts of Timers but nothing that can regulate On time. Guess I'll have to build a 555 or transistor timer of sorts. I can regulate the Current some what using like 8 AWG wire but even that is too much. will try 12 AWG . Doing that it really wouldn't be of much use for anything else. Really don't need much. I have a 15 Amp Veriac that may work but really don't want to toast it trying. Anyone out there have Idea's ? These MOT transformers are a Hoot. Made a Kick Butt Battery charger with one. You really don't need to cut the Coil Core. Just hack saw threw the Secondary and punch it out with a Bolt. You can twist up just about any transformer you would ever need with the dang things. Ell you can even make a 12 - 24 volt to 120 volt Inverter with them.
If you need a high amp relay (60A), I sell a latching one that is controlled by 5V. You just need a circuit to turn it on and off. www.ebay.com/itm/132440059832
Incrível! Alto nível de detalhes e muito bem explicado. Obrigado por compartilhar seu trabalho!
You are welcome!
대단한 실력입니다.철판은 몇미리 까지 용접 가능 한가요.1대 가격은 얼마인가요
The air inlet needs a lateral outlet to perform an effective cooling function.

Здравствуйте. Сделал «точечную» сварку с трансформатора микроволновки. Вторичку намотал кабелем 70 кв. На выходе 1,8 вольта и 1400 ампер при коротком замыкании (мерил клещами), два витка. Электроды медные проточены под конус. Но не сваривает вообще. Проволока диаметром 4 мм сваривает а листовой металл (оцинковку 0,5мм) вообще не варит, греет докрасна но не сваривает. Подскажите где я заблудился в чем проблема?
Hello Michael! What model of Triac did you use? The one that is in the dimmer circuit. How much amps can it drive? Greetings from Venezuela!
awesome
Hello. Very nice job. Could you please tell me what the copper "contact tips" are? Are they used for the TIG welding torch? They look similar but I think they are not. Thanks in advance.
nice work sir . one question : fan is pushing air into the transformer housing or pulling it out ? in any case where are the circulation ventilation holes for the air go thrught it?
Thank you! In front of the machine, from output cables hole

Everything is beautiful, but there are 2 questions. Why is there light inside? And there are no holes for normal air circulation. How will the air flow cool?
I can see the light through cable's outlet hole (on the front of the box), which is for ventilation too. Thanks
still didn't answer the question as to the purpose of the light and the small slot where the cables come out does not appear to provide nowhere near enough air exit space therefore creating an increase in air pressure within the cabinet thus trapping heat OR if the fan is drawing air in through the cable slot then there is still not enough open space to allow enough cool air to enter and is also creating a slight vacuum that will pull in more dust than if the both entrance and exit source of air were balanced. However, this is probably only for the occasional use which wouldn't matter much for circulating air. Why is the fan on a switch. It should come on at the moment the transformer is powered up. It is easier to keep it cool from the start rather than try to cool it down after it has gotten hot. Very ingenious. I like it.
hola buenas noche y disculpen el idioma aver si alguie me puede traducir y decirme donde a comprado este señor el circuito integrado y como se pediria muchisimas gracias.
great job the light also give you a hint it's on "screwfix " earth rod would also work for tips comes in 4ft lengths code 28044. did you cut out the ground in the main feed wire?
Who made this music? I like this musical composition
Price of the Spot welding machine . I'm interested in buying instead of assembling by myself . Need lot of time to run back n forth in search of the Transformer & attachments .
muito show! parabéns!

I'm guessing you are in Europe or another country where the standard is 220VAC, what value would I use to replace the control unit you cannibalized from the vacuum? I live in the USA and our voltage standard is 115VAC. Great job with this project and very good visuals, keep it up.
Luar biasa
127 v 220v???
can you give more description on the power controller you're using ??
You can use a Dimmer (AC Controller)
Is this cheaper to build than the $139 one at harbor Freight?
Where did you get the electrode holder on the end of welding arms. I cann't get one.
Can you provide us a link to e-shop eventually?

Que buen aparato
¿Porque la lampara?
Lo aces bien tío pero las medidas porlas en español tambien
You take the controller from an 1800W vac, which is designed to control a universal motor, and use that to control a transformer which is going to need around 3KW? I'm amazed it works.
190W min - 2100W max
It'll work because its momentary current, not a continuous run. The ratings are always average over time, unless the manufacturer says otherwise.
where is the power controller on this circuit ?
Ou je trouve cette appareil et qu'elle est le prix de celui-là
Why do you want to install a light bulb in the cabinet..? I guess it's acting like a resistor, or am I wrong..?
Its just visual indicator when noisy

Thank you!
Is it possible to just add a on/off switch and a Rehostat an (adjustable switch ) or a micro switch like you have at the contact points with the fan of course, or can you display the wiring schematic, that is an awesome setup. Thanks for sharing.

Бляяя чуть не уснул.Особенно понравилась лампочка не к месту
монтаж оставляет желать лучшего) особенно лампочка внутри это верх гениальности, которая если что Вам поплавит изоляцию внутри. Система охлаждения работать не будет, нужно сквозной делать, тогда ламинарные потоки будут обдувать трансформатор и выводить тепло, а так пустая работа кулера, гоняет внутри воздух по углам.
15w лампочка, даже воск не сможет расплавить. Сквозное отверстие для вентиляции находится спереди (отверстие для вывода кабелей), через него же видно и свет лампы которая загорается только когда обмотка задействована
