The microwave oven transformers generally have high standby (core magnetizing) currents, that's one of the reasons the fan is always on when a microwave is in use. You seem to have all the tools, you know how to use them skillfully, and you have good sense and talent for getting stuff done with them. I admire that and wish you great success. Greetings from Bosnia!
Thanks for showing what can be done with a little bit of thought and inginuity. You also "rescued" some transformers that would otherwise have gone for scrap, but proved to be perfectly usuable.
I see there are lots of brilliant minds on this thread, Love it. I didn't get a clear picture of the corelation of primary and secondary wiring, how they merge. However, lots of brilliant think tanks pick that idea up and run with itl; but still the guy who labored first, get the kudos...lol. Shout back at me.
Sean Beardon .....you are the one who show us things in practically....forget those who say blablabla...only seatting infront of the PC and having master or Phd...on theory (bla...Bla..)....YOU Sean keep posting such kind of creating things. Bless you.
Nice machine ! Hay, I had a thought for you. You do know you can make your arc welder adjustable to accommodate outputs. You have 4 right, just power up 1, 2 , 3 or 4 transformers by toggle switches. Then you will have low, medium, high, and full power settings for different thickness meterials. Enjoy
Actually this will not working properly. The ouput voltage in the secundary will drop when shuts down every transformer. The welding voltage for arc is around 38 volts. So every time you shuts down one transformer the voltage output will drop also.
sounds nice in theory, but ibelieve there would be voltage drop. But anyways, like he stated in the beginning of the video, he already had a lower duty welder and was just building this one specifically for heavy duty jobs... But, your idea is interesting and creative... have you copied the build and applied your toggle switch theory? How did it turn out?
awesome job, very well thought thru and your skill is shown very well. i make a lot of the stuff we need around the shop. we have 2 welders and a plasma cutter but we are definitely going to keep this in mind because we are going to attempt making a tig welder thanks to watching your video, knew it was possible but not that simple. thanks for a great video
Dam it’s one thing to build something yourself that will weld at all but to have it weld so nicely like this one appears to be doing. Damn nice job. Looks like you’re using professional equipment when you’re actually welding. Very impressive
Thank you for sharing. Because the transformers are close to the transformers, they will block the magnetic fields during the work, which will cause the amperage to fall on your machine in my theory. my opinion is, if you put the second group transformer down the hill, both of them magnetically support each other, this will keep your power loss to a minimum. Greetings from turkey
Looks like it works well. That 11 amp draw might be the fact that there's 4 transformers in the circuit as opposed to one, so they might have some magnetic resonance on standby, I'm betting each one is drawing around 2.75 amps when this is happening. Probably not good to make it out of wood, but hey it works lol!
The transformers iron core is small compared to its primary coil, microwave transformers are made this way, I cannot remember exactly why they are made this way though.
Goldsmith MASTER Jeweler here: my hat off, standing ovation, cha cha cha etcetera etc... very impressed. Photovoltaic, solar thermal technician too. video well edited Current at the Socket and Current at Arc got a great WOW from me. i still am able to read blurry subtitles. constructive criticism, maybe a, Nah, scratch that idea, it would block the visuals LOL strain eyes a bit ain't gonna kill nobody even if we go blind LOL. i Like, OLE!
great job, i love how creative people can be :) I am Retired but I would like to buy a Mig welder for my garage, I miss welding, been doing welding for 40 plus years on the job, I had a Lincoln 225 amp buzz box, Bought it when i was 16 Years old :) but a mig is Nicer :)
I've done that method and it's awesome, but I have to say, slitting the welds with an angle grinder or maybe Dremel, and removing the coils intact has proven to be a simple, repeatable process for me with nice neat results and low risk of nicking the primary.
You forgot to put in an ammeter and build a rheostat, so you could control the output of the welder. That would have been brilliant .. maybe your next project ..
TO ALL: remember, these microwave transformers have a shorter length of wire, on primary. Microwaves are always started UNDER LOAD, so, make sure you are ready to use them, (in whatever your making) only when your LOAD IS READY TO BE USED. You can add windings to primary, to extend onTIME, no load. 270 turns,. for 120 volt source line, should be sufficient, depending on the wire gauge.
How do you add windings to primary? Probably need to find the same gauge wire, no doubt.. the windings is where I struggle I don't know how many turns are on the primaries
Very cool project. The only comment I have is regarding the cuts on the secondary windings. For those of us without a cutting wheel, and possibly cutting by hand, only one side of the windings needs to be cut. The rest of the intact winding can be pounded out from one side just as easily.
Ok this is from a engineer. Number 1 if welding the transformers was such a bad idea why is this common practice in the industry. Number 2 he has a fan . Number 3 if one of the transformers were out of phase it would pull a lot more that 8 amps lol. Number 4 so what if it's wood if it caught fire the fan will put it out or it will fuel the fire 😂 . IT works good job have fun and keep on building. If it has a 1% duty cycle that's 1% more than you started with😁👍
@Maria Madalena Lima Mi Reina, but we live for the thrill even if it kills us LOL speaking from actual experience as in Hands On or theory. either way I will show your comment to my princesita 11 yrs old and show GIRL POWER. OLE!
Plus he knows whats he's doing and if using a 12 V battery there's also no current control and low open circuit voltage. You Saw It, You Called It. Kudos, and great example for my little girl as to always point things out. That being said, I shall take my leave.
OK, the way you got those secondaries out is BRILLIANT. Far better than how I did it. It's so funny that you made it look like a commercially made welder, but I really wonder how hot it gets inside that wooden box.
Awesome build! I really like the looks and the handle of the enclosure you built for it. Btw, the high current without any load is mostly reactive power. Those microwave oven transformers are driven very close to saturation. But excellent job anyway. I really enjoyed watching this.
I remove the windings with a sharp flat sided single edged chisel (initialize starting cuts from every direction to compress the wires) the drive them out with a square tipped punch, its the simplest and fastest way I’ve tried so far, sawing drilling were messy, and quite a bit more time consuming
80° C after ONE minute of welding. Decides to put it in a wooden box... Welding transformers cores together is a very wrong idea. You create stray magnetic field that go in unwanted directions.
Muito bom!!! Gostei demais,a minha máquina de solda queimou,e estou sem dinheiro pra comprar uma nova, depois de ver esse vídeo eu vou fazer uma desse jeito, gostei da ideia,ela é simples e funciona. Ok
Well done. Excellent. A very detailed and synchronized explanation. The only correct way to cancel your Google Account on your phone. They charge a lot for this in the service and hide how it is done, because it is obvious that anyone can do it. Thank you for sharing this with us.
This is a neat idea. I think if you would have used enamel coated wire you could have used a lot larger gauge wire on this and produced more current per transformer for the same number of turns of wire. Or you could have used the same gauge of wire you used but with enamel coated wire you could have put more turns of wire in the transformer. This would have given more volts out of each transformer and possibly eliminating one transformer. You never want to weld the laminated core together in a transformer as this defeats the reason a transformer has a lament core. Welding the core make the transformer run hotter and decrease its efficiency through eddy current losses. Still it is a neat idea. Thanks for sharing.
I don't know seems to look like it works very well to me with the wire that he used always somebody out there trying to tell you how to do it better I built one about 6 years ago and it works great refuses to burnout and fuses to get hot just works great
Nice video! Does anyone have any thoughts about adding cooling fins or some type of heat sink to the transformers, and how you would go about doing it?
im hapy i came across this now i dont have to spend 300 plus dollars on a real welder when i can take my time and make one from old microwaves apprecait the video man made lide alot easier for my gocart upgrades
Nice job you made but it lacks current adjustment, You could reduce the input current by adding a 25-35uF run capacitor across the mains near the transformers. This would reduce the inductive reactance and correct the power factor hence less input current.
Add a VFD ,a couple pot meters, 2 capacitors, a breaker, and you could have any kind of welder you want. I made tig / plasma cutter a few years back, it runs as good as my Miller.
Awesome job. The only thing I can suggest is to put an on/off switch. Problem is probably finding a big enough switch to handle the current but there are ways around that, ie: relays, contactor. Otherwise, you did a great job.
Great job, but AC Voltage high like this is very dangerous for healh. You should use simply eletric choke if you dont won to use rectifying diode. A few turns of coil on single core. You can make a power regulation with taps between transformators. Cover is 11/10.
Nice video. But, in my opinion, is not a good idea the welding between the two transformers, because it creates an electrical conduction among the transformer plates. It means more losses.
I noticed no difference in the welds it made before I welded them together, also I have a welder made by a proper welding company, I had the cover off a few months ago and found 2 transformers welded together, maybe it makes no difference
There is no difference because transformers work through electromagnetic induction and not the same exact principals as other types of current components. Sean did a good job welding them together.
I agree it would be great except I don’t think the school would encourage children to work with such dangerous voltages well any voltage is dangerous so who knows
Are the stand offs for the fan made from insulated material ? If not you need to add a protective earth onto the Fan as you have 2 bolts sticking through your back panel which could potentially be live should there be a problem with the fan
parallel primary. imagine the electric bill it cost. it goes super hot in an hour of continous use. mine i series 2 pri coils and parallel it to another coil.
Yeah, 11 Amps is a lot. It is due to having a shunt. He said later he removed the shunt and added 2 more turns on the secondary. Removing the shunt will reduce the current. However with the shunt the circuit is protected from short circuit which is what happens during welding. Theoretically this is capable of Np/N2=Is/Ip = 200/10*11=>200 Amps, but 6 AWG is not enough for 200 Amps, so this is not a 200 Amp welder. Maybe for 10% duty cycle operation? So with a 10:1 turns ratio = 240/10 = 24V. So why is the open circuit voltage = 37 Volts when the secondaries are in series? Theoretically they should be 4x24V= 96V. It is the shunt causing a lot of leakage inductance between primary and secondary. Normally, one does not use a welder all day long. it is used for several minutes. He can turn it off when finished.
Sean,I have so much respect and admiration for your craftsmanship, but what Massimo is saying essentially is 100% true,the phenomenon called eddy currents makes it compulsory for transformer laminations or laminae to be first of all hysterically zero, i.e made from soft iron or ferrites,secondly,be as thin as possible, thirdly, be electrically but not thermally insulated from each other,having said all that,it's also proper to point out the fact that if need be,it's also possible to weld across the lamination or laminae provided the size or the diameter of the weld line is kept at the barest minimum so as to keep the size of the eddy current around the laminated core minimal, hence keeping losses under check since the two are directly related
Also if you wanna be cute and make your own welder out of wood, please put a circuit breaker in there so a fault does not start your whole thing on fire.
Not a good idea to weld two transformers together. It will cause problems later . Your changing the inductive reactance of the transformer. I read in a technical manual keep transformers away from other inductive devices. #2) I would of added a lighted power switch to the welder . Also slow blow fuse or circuit breaker for safety. Overall Nice job!
Í think you got a point there. Í Love the craftmanship of this guy a real neat job. As you mention. Í will issolate the transformers with a 1/4 inch rubber mat on bottom, betwen and top. Specting to reduce vibration and noise .
The transformers also work less efficiently as well. The laminated metals are now connected - which defeats the purpose of increasing the efficiency of the transformers.
Welding the transformers together would now make the plates a circuit, which will act like one giant single short circuited coil. It will heat up and damage the actual coils prematurely. Other than that, great idea.
You my friend are absolutely right there is always some negative Nelly out there who wants to add his bullshit into the situation but yet they have not built one their self but they can tell you all the things that you were doing wrong funny how that works I built one six years ago and it has never failed me yet but I know if I was to put it on UA-cam there would be at least 10 people who would be telling me where I screwed up when I built it LOL
I believe that this welder could melt 6061 or 6063 aluminum alloy electrodes, which are said to be DC only, nicely. Heck! it could melt any DC electrode just fine and I saw the Precision TIG as well as the Stickmate melt E6010s on AC just fine.
I doubt it my 4 transformer welder runs very cool with a single fan inside even after welding for quite some time. The paint also helps insulate the wood from the heat.
Je crois que l isolation des fils rouges du secondaire ne peuvent pas résister longtemps a la propagation de la chaleur dégagée de l usage prolongé du poste a souder/Il faut utiliser du fils émaillé/ou isolé avec une gaine en amiante/
It sounds like you guys should try capitalism for a change. Here in Texas, I have a standard, 48KW residential service and pay $0.08 per KWh. 3 KW wouldn't run my dog house and a beer cooler. Socialism sucks sump sludge.
When you connect transformers in series, you regulate plenty of current but if you want more current from this welder, then you gotta connect the transformers in parallel. However, connecting them in parallel will be pain in the ass, so connecting transformers in series is better, so that you get better control of the arc.
amazing, we suffer all the nonsense crap like cutting and painting the wood to make a box which no one needs a tutorial on but then don't provide the kind of things that people can really to build it use like the size of wire used for the transformer and a wiring schematic so people know how to safely wire the welder......
Amigo. Alguno de los cables tanto el tierra como el porta electrodo dan dolor de corriente. Lo que me preocupa es saber si la tierra da golpe eléctrico. Y que pasa si la hago con dos transformadores.?
Hola, no sé si pueda o tal vez pueda contestar a tu pregunta ya que no quisiera molestar al creador del canal, está máquina la hice hace 10 años, los problemas que encontré fueron el bajo amperaje, el control del campo magnético, el calentamiento, en fin una clave en esto es menos vueltas más calor, ahí tienes una solución, si quieres potencia, pon en serie los dos primarios para que utilices 220, si en tu país es común, pero si no 110 provocará calentamiento , en fin puedes empezar con un transformador si el primario está a 220, en caso contrario como en México los microondas vienen a 110, pero puedes experimentar, recuerda que la energía eléctrica es peligrosa y tendrás que tener cuidado mucho cuidado, saludos
what about 3/16 or 1/4" plate, I think you will burn through, neat construction maybe you could tap into 3 transformers to lower amps, just a thought good vid thanx
Well I built one about 6 years ago and it has not burned up yet mine works great so I don't know where you got your information from that it would burn up in a week because mine refuses to give up at any point

I've done that method and it's awesome, but I have to say, slitting the welds with an angle grinder or maybe Dremel, and removing the coils intact has proven to be a simple, repeatable process for me with nice neat results and low risk of nicking the primary.
You forgot to put in an ammeter and build a rheostat, so you could control the output of the welder. That would have been brilliant .. maybe your next project ..
At these high currents, a rheostat is impractical because of its required size as well as the contact resistance which becomes much more pronounced.
That cost you can do the same thing with creative wiring techniques.
Couldn't you modulate power by switching transformers on/off, or running them in parallel vs series?
I love the upside down jigsaw ghetto band saw. I've done that in the past when it was necessary. Good thinking Batman

Large heat sinks from desktop computers are an ideal size for the sides of those transformers. They could be screwed or clamped on easily.
You can use a motor variac controller to adjust the current and the voltage

So with a 10:1 turns ratio = 240/10 = 24V. So why is the open circuit voltage = 37 Volts when the secondaries are in series? Theoretically they should be 4x24V= 96V. It is the shunt causing a lot of leakage inductance between primary and secondary.
Normally, one does not use a welder all day long. it is used for several minutes. He can turn it off when finished.
Brother kuch bhi ho apko to mann na hi padega.thanks bhai ji.AWESOME
Put a bridge rectifier on the secondary so you get DC instead of AC, helps alot with penetration.
I've made one with 4 MOTs. It gives 36V AC, 250 Amps. What are the benifits of converting Ac to Dc in this arc welding? What rectifier is to use?
Sean,I have so much respect and admiration for your craftsmanship, but what Massimo is saying essentially is 100% true,the phenomenon called eddy currents makes it compulsory for transformer laminations or laminae to be first of all hysterically zero, i.e made from soft iron or ferrites,secondly,be as thin as possible, thirdly, be electrically but not thermally insulated from each other,having said all that,it's also proper to point out the fact that if need be,it's also possible to weld across the lamination or laminae provided the size or the diameter of the weld line is kept at the barest minimum so as to keep the size of the eddy current around the laminated core minimal, hence keeping losses under check since the two are directly related
Did not show shit
You are right. By welding the laminated cores you are short circuiting them.
good
Also if you wanna be cute and make your own welder out of wood, please put a circuit breaker in there so a fault does not start your whole thing on fire.
@@alokt7119 No. You are wrong.
This guy is amazing. I subscribed to ya keep it up I'm hooked
Τέλεια η κατασκευή της ηλεκτροκολησης .
Also make sure your primary has only 120v and 220v , A 480 volt one will take up more primary coil room giving you less secondary room.
buen video, gracias por compartir, que tipo de cable usas en las vueltas de los transformadores y cuantas vueltas hace para cada transformador
Te contesto tu pregunta yo tambien quiero saber el gruesor del cable
Probablemente sea cable de 6mm2
florencio cable #10
Excellent job.
Nossa foi a melhor maquina caseira que eu vi na Internet Parabéns.
Waow
Great great great
Thank you

Not a good idea to weld two transformers together. It will cause problems later . Your changing the inductive reactance of the transformer. I read in a technical manual keep transformers away from other inductive devices. #2) I would of added a lighted power switch to the welder . Also slow blow fuse or circuit breaker for safety. Overall Nice job!
Rather glue with epoxy
Í think you got a point there. Í Love the craftmanship of this guy a real neat job. As you mention. Í will issolate the transformers with a 1/4 inch rubber mat on bottom, betwen and top. Specting to reduce vibration and noise .
The transformers also work less efficiently as well. The laminated metals are now connected - which defeats the purpose of increasing the efficiency of the transformers.
Welding the transformers together would now make the plates a circuit, which will act like one giant single short circuited coil. It will heat up and damage the actual coils prematurely. Other than that, great idea.
Good idea if U live in Siberia and U do not have access to Harbor Freight although might be hard to find Steel🤔
You can buy Amico Power 160 amp stick welder about $150 amazon ebay home depot and weld 7018 1/8 even 5/32 all day. 110 and 220V
Yeah you could.......but anyone can do that. I'm sure this guy could afford to do that as well but it's way more gratifying to build your own shit
joe eastman
True!
All these projects are basically about using the mind, the skills and enjoying the moment from start to finish. ;)
true, but who would build it?
cheaper too. can get free microwaves on craigslist if you're patient. i have 2 so far
I want to buy this machine, Mr. Beardon. Amazing job.
Thank you for the video, I can do the same and add a thermostat to shut down the machine when it's over heat. And then on a light
He will not need, put a fan behind it, he will let the whole heat out
Good job Sean although I think if you came up with a way to create free energy you would still be criticised.
You my friend are absolutely right there is always some negative Nelly out there who wants to add his bullshit into the situation but yet they have not built one their self but they can tell you all the things that you were doing wrong funny how that works I built one six years ago and it has never failed me yet but I know if I was to put it on UA-cam there would be at least 10 people who would be telling me where I screwed up when I built it LOL
It was great. How many turns did you give in each transformer and which wire did you use?
10 turns per transformer and 10mm2 (I don't know what gauge that would be)
Sean Beardon thanks for listening. won one more subscriber
@@projectmayhemUK looks like it might be 7 gague possibly 8
@@hilham89 couldn't you have used a bigger wire for the secondary with like 2 wraps on just one transformer and gotten the same amps or even more?
@@projectmayhemUK thats like 6 gauge
That is quality mate, I would like to see a way of varying the output though to cope with different gauge metal. Great work
Variac
I believe that this welder could melt 6061 or 6063 aluminum alloy electrodes, which are said to be DC only, nicely. Heck! it could melt any DC electrode just fine and I saw the Precision TIG as well as the Stickmate melt E6010s on AC just fine.
The platform wood will burn after some time
I doubt it my 4 transformer welder runs very cool with a single fan inside even after welding for quite some time. The paint also helps insulate the wood from the heat.
No security ? No fuse ?
there is a 32 amp switch on the power board
theres legit a fan
Kamikadze...😁😁😁
@@projectmayhemUK a switch on the power board is there to secure your power cables, not your equipment.
Use high current diodes and supercapacitor for make DC voltage. AC is very loud!
Very good work... Nice looking project! Just doing it because we can....
Je crois que l isolation des fils rouges du secondaire ne peuvent pas résister longtemps a la propagation de la chaleur dégagée de l usage prolongé du poste a souder/Il faut utiliser du fils émaillé/ou isolé avec une gaine en amiante/
excelente. ustedes ponganle todas las seguridades que quieran pero ya ven si so puede.
Francisco Melchor F. So beautiful work.great job
Man you are a awesome artist
BRAVO MAESTRO
32 amperes are about 5-6 kw. For an Italian family with a standard 3 kw contract it can not be used
Si ma lì il voltaggio è 120v, quindi hai più o meno 3 kW
@@CVP-og9pw ok allora tutto torna!
It sounds like you guys should try capitalism for a change.
Here in Texas, I have a standard, 48KW residential service and pay $0.08 per KWh.
3 KW wouldn't run my dog house and a beer cooler.
Socialism sucks sump sludge.
@@rickoshay6554 48 kW? That's a freaking lot of wattage for a house!
@@rickoshay6554 usual max power for residential houses is 3 kw, but you can choose from 1,5 up to 6 kw. After 6 kw you get three phase current
No current regulation?

When you connect transformers in series, you regulate plenty of current but if you want more current from this welder, then you gotta connect the transformers in parallel. However, connecting them in parallel will be pain in the ass, so connecting transformers in series is better, so that you get better control of the arc.

Well done welder! Thanks for sharing.
Diy nice project, in microwave oven it has thermo disc that can be use as cut off in case of overheat..
amazing, we suffer all the nonsense crap like cutting and painting the wood to make a box which no one needs a tutorial on but then don't provide the kind of things that people can really to build it use like the size of wire used for the transformer and a wiring schematic so people know how to safely wire the welder......
Amigo. Alguno de los cables tanto el tierra como el porta electrodo dan dolor de corriente. Lo que me preocupa es saber si la tierra da golpe eléctrico. Y que pasa si la hago con dos transformadores.?
Hola, no sé si pueda o tal vez pueda contestar a tu pregunta ya que no quisiera molestar al creador del canal, está máquina la hice hace 10 años, los problemas que encontré fueron el bajo amperaje, el control del campo magnético, el calentamiento, en fin una clave en esto es menos vueltas más calor, ahí tienes una solución, si quieres potencia, pon en serie los dos primarios para que utilices 220, si en tu país es común, pero si no 110 provocará calentamiento , en fin puedes empezar con un transformador si el primario está a 220, en caso contrario como en México los microondas vienen a 110, pero puedes experimentar, recuerda que la energía eléctrica es peligrosa y tendrás que tener cuidado mucho cuidado, saludos

what about 3/16 or 1/4" plate, I think you will burn through, neat construction maybe you could tap into 3 transformers to lower amps, just a thought good vid thanx
Very nice welder mate , very smart
Bravo 🇹🇳🇹🇳🇹🇳🦁👈👍
Get stronger coller -or this will burn in a week!

Well I built one about 6 years ago and it has not burned up yet mine works great so I don't know where you got your information from that it would burn up in a week because mine refuses to give up at any point
Nice thing about wood is that it makes a great insulator.
I use a 1000 watt metal halide transformer ballast. Plenty of secondary room .
Very nice. You really did a great job!
Wow!!! Great job very very nice!! You have inspired me to build one!
Nice project.
Fabuloso video!! Más allá d todo es excelente la ejecución y prolijidad!!! Muchas gracias, saludos desde Uruguay
