First of all, this is legit. But the video should be called: How to build a spot welder out of ONE microwave part and 50 other things you need to have...
I am a light bulb on my channel new video every day! SUBSCRIBE
Hahaha true
What are those 50 other things?
Spot welder = $180.00
Rigged microwave/spot welder = $750 + your only day off...
*provided EVERYTHING goes PERFECTLY
A lot of people who work on things already have a lot of that stuff. If my microwave stopped working then I can do this and it really wouldn’t cost anything just time.
Never knew that smashing something with a hammer also neatly disconnects the internal wiring. Learning every day!
New video every day click to light bulb! and subscribe dont forget!
Cool build! If anyone tries this & takes a microwave apart, stay away from the big HV capacitor or discharge it safely - they hold charge for some time and will happily kick a couple of thousand volts into you if you're not careful.
Yep, to discharge it safely slap a resistor (1kohm should do the trick) on its terminals and leave it there for a while, you will be able to measure 0V at the terminals once it's fully discharged
Indeed, discharge the capacitor first. I was AEG technician. Discharge with insulated pliers (electrician tools, not your hobby pliers) is also possible.
@@geerttampere6765 just short it with a screwdriver, and you get a big spark if there's any juice in it. Even the most sihtty screwdrivers have excellent insulation.
@Jo Veteran. I know. I did it also like that if the pliers were not in the neighbourhood. But I don't recommend that in public 😜
Yes, and if you don't know what that is do Not attempt this
Thanks to the low number of dislikes, I can tell this project is legit and totally safe!
Thanks, TH-cam!
LOL noice
More like absent dislikes fym
You can still figure out from ratio of likes to views. Less than one percent is kind of trash.
@@Twigpi the like/dislike count never come anything near the views.
@@thatguy6214 Hence why a ratio is applicable in this situation.
Some people are just ridiculously gifted. Good job man that was awesome
The difference between a “gifted” person and someone who thinks they’re not is deciding something you’d like to do and then doing it. All the resources are at your local hardware store and all your lessons are right here on the internet. Don’t be jealous. Just do things or decided you’d rather not and be happy with it.
Some people are ridiculously gifted with engineering skills at what they went to school for 🙄.
Smart guy...nice piece of equipment
It really wasn`t that complex what he built from an electrical/engineering point of view.
It would have been very helpful if you provided a list of materials and how/where to source them.
good job not mentioning at all how dangerous this is
I don't expect kids are doing this lol. Someone whos doing this probably already knows the risks of breaking open a high power transformer.
@@MrChesemisI wouldn't bet on that, at all.
1. Sleeve for the mains cable going through the metal cover
2. Strain relief for the mains cable so phase wire doesnt come loose and energize the metal cover
3. Ground the metal cover (maybe you cut out the part where the loose yellow green ground was attached)
I would 100 % use a plastic casing for a high stakes DIY project like this. Just 3D print it. Don't want to risk it the amount of amps getting pushed through that transformer is no joke.
@@mithrandirthegrey7644 amps are high at the very low voltage only. On mains side the amps aren't more than only 4-5 A for 230V microwave oven. Grounded metal cover/case/structure is the only way to go. When you look at the industrial grade power tools, all high performance machines are designed like this.
I once did a spot welder out of a faulty microwave too but it was for my engineering degree. For those who are wondering, yes it works exactly like that and it is very cool. Mine was way uglier and had almost zero safety, but was worth a top grade on our semester project
Cool
Do you know the what that yellow item was towards the end?
@@MN-sc2uz i am also looking about the yellow small item which is connected to transformer
What gauge wire would you suggest? Thinking 3/0
That's cool, this one is totally unsafe too.
Good build over all. Only thing pup recommends is adding a rubber gasket in the steel casing where the main voltage wire comes in. Over time it will cut through the wire and will arc and short it self!
Better yet a cable gland, it would insulate and act as a strain relief so it doesn't rip the live wires from the wagos and make the whole case live
Stay quiet? We're providing a simple, yet highly effective safety measure...
@R. Bito don’t be racist
@@goldmemberr 😂
@R. Bito Dude be quiet if you've got nothing intellectual to add.. some of us love extra information
This went from a "how to" to "good luck figuring out what I just did there" video real fast. This should be called "watch what I can make out of broken appliances"
Yes
Clickbait. - It's just an used modified voltage transformer. - Luckily ;) :)
If you don't understand what's going on, then keep your fingers out of microwave internals. You are not worthy.
I bet you can understand those useless TikTok videos
He destroyed an entire microwave just to use its electric coil 😂
The finished product looks store bought. A detailed set of plans and product lists would be greatly appreciated. Nice job!!! 🤗
+1
Let guess you don't want to pay for them either. Really rude dude.
I want more info! It not I dont dare to make it. Bu I really want it!
@@richb2752 right 🤣 be this such an easy build I don't think I'd need any plans for it come on you got two eyeballs don't you people?
Agreed, a simple wiring diagram would add so much value to the build. Sure we can figure it out ourselves, Just saying.
Power lead straight through a metal case without any gland. WOW!
I saw that, too. Definitely need a grommet with strain relief.
I came here for a home made DIY spot welder video
Instead I got a professionally fabricated to precision spot welder video.
Very amazing skills and quality. Perhaps even better then whats sold in hardware stores.
New video every day click to light bulb!
Except he's not showing how to discharge the capacitor. That's going to hurt someone.
@@percyfaith11 what capacitor?
@@jonathan5269 There is a capacitor in close proximity to that coil he is removing. If contacted it can cause serious injury.
@@jonathan5269 they are talking about the one in the microwave
I'm very impressed. Awesome build. If only it was as easy as it looks. Double thumbs up
Your impressed?? With THAT garbage 🤦♂️🤣
An excellent build, good eye for detail right up to the aesthetics 👍👍👍
Professional? Yes. Great video? Yes. DIY? Not even close.

Seriously well done! 👍 Looks good as well!
I love how there's no safety warning for the multiple potentially lethal components inside a microwave
A microwave transformer is probably one of the deadliest things you can have in your home. Way too many people die messing with it because they don't know enough electrical engineering to be safe.
Someone's going to end up copying this and it will go wrong.
@@originalityisdead.9513 That's what I'm worried about
@@danilooliveira6580 I've just looked it up and a quick search showed up to four people in the US each year are killed when taking apart a microwave.
@@DJCloudy_ I'd imagine people would be doing a Google search along side taking it apart though. It still wouldn't take much to put a disclaimer at the beginning and end.
Built one myself once, the sleave on the thick high amp cable starts to melt after only a few welds. So yeah it is possible and works great but make sure u buy cable with silicone sleaving not plastic sleaving and remember its only for a few welds at a time. 😀👍
Did you try to use MMA welding cable? Maybe are tough enough to resist more then regular PVC insulated cables.
Better crimping too
Actual welding cable and a proper crimp tool are key
Hi guys.. thanks for all the tips, yes i bought propper cable from a welding shop, but clearly as i discovered you need cable with either rubber or silicone insulation as the normal plastic, pvc doesnt do the job. As for the crimp, i not only crimped but also soldered the joints so contact there were very good😀😄👍
If your wire insulation is melting, it's not the insulation material. Rather you undersized your conductor (wire).
Great build but there can be serious high voltage charge remaining in capacitors inside the old oven. 3000volts discharge can be nasty if the wires contact the bashed casing.
The only way that might shock you is if your body completes a circuit path across the two terminals of the capacitor somehow. Bashing the oven with a hammer that has a wooden handle isn't gonna do it. Neither will touching only the case. The only time I saw a chance of that happening was when he removed the transformer.
I'm not certain, because I haven't seen a microwave oven schematic for a while, but I believe that the capacitor is connected in parallel with the secondary winding of the transformer. If that is the case, there's no way it could hold a charge.
But, if you're still worried about that, just do what we TV techs used to do with the old CRT type televisions. Remove the cover. Yes, you can do that (contrary to what the manufacturer may tell you) without getting shocked. Just make sure it's unplugged first, and don't just go sticking your hand (or any other bodily appendage 😂) up inside there while touching the case. Next, take a well insulated screwdriver and stick it across the capacitor terminals first thing, immediately after removing the cover. That'll discharge it for sure.
@@lewis2553 I stuck my hand in the VCR one time a got shocked when I was a kid. LOL
@@lewis2553 nope! High voltages means that air can be a wire. Ask me how I know. Keep your left hand in your pocket and you won't be dead but microwaves are the number one killer of electronics hobbyists. We should not be advising people to open these. It's not just one capacitor like a crt.
I thought the same exact thing. Capacitors kill! Back when I did a bunch of scrap metal salvage mainly copper bronze and aluminum I always kept a probe to drain them whenever I came across them. Some ended up being hot some not but that's better than finding out the hard way
If someone knows enough about electronics to be able to build a spot welder from microwave parts, chances are better than zero that he/she will be aware of the supercapacitors and how to discharge them.
Great attention to details , one of the diy videos that did not find any inconvenients, except too thin wires on the 220v line and the need of a relay that can sustain a little bit more amps
The magic smoke will cause a rebuild.
Question, how would the relay help?
Someone mentioned that you need 50 more things besides microwave, I'll try to name them all:
Sledgehammer
Metal saw
Rotary cutter
Hammer
Hammering chisel
Thick gauge wire
A special fan
Plywood
Wood glue
Battery drill
Aluminum angle mount
Wire cutters
Knife
Wire lugs
Lug crimping tool
Heatshrink tubing
Torch
Compressor for pneumatic nailgun
Lug mounting brackets
Saw foe cutting up plywood
Drill press
Drillbits
Wood crown drilling bit
Springs
Various bolts
Ratchet wrench
Angle grinder
File
Sandpaper
A tap
Copper welding contacts
Push button
Hookup wire
Metal sheet
Holding clamps
Angle iron for bending metal sheet
Step drill bit
Relay (this type is not in the microwave)
Wago connectors
Electric warning sticker
Anyway it looks and welds pretty good

All that, but no screwdriver to take the cover off.
Felicidades, la verdad que es una maravilla ver como la gente tiene tanta creatividad y conocimiento 💪💪💪
hi what?
Basic concepts explained without long winded explanation.👍thanks for the refresher. Subscribed!
Nice work! Looks professional.
I have absolutely no idea of what I could do with this but this is amazing!
Most of us spot weld lithium batteries, after we buy a few fire extinguishers.
Most car skins are spot weld together so it's useful for auto body work
Восторг! 👏 Браво мастеру!
This is one of the best diy video on TH-cam.
Simple straight and it works too.
Great job👏👏
Check out Grant Thompson over at "The King Of Random" DIY welders and things like that when he ran the channel before he died
Good running commentary there of dimensions, materials and components that you used to make it.

Questo video mi è piaciuto moltissimo. Fantastico! Ne ho visto tanti come questi, ma questo è il più bello... Bravo 🤘🤘🤘
Clearly perfection, perfect filming and presentation and likely a fun tool to use. Definitely one of the top 10 presentations. Thank you man.....
That's the best one I have seen ever. If heard about this for decades. Wish u would of explained the component ,and pin arrangement. Either way bro thanks for helping with the idea . Awesome!!
Passion marries professionalism, they give birth to the twins of pleasure and productivity.. well done
And create a video that will get a bunch more people killed who should never mess with a magnetron.
The guy making this video is really irresponsible.
I am impressed, I love this kind of stuff. You ROCK!!!
You are unbelievable, love the video . Your creativity is amazing. Thank you for sharing your ideas. Looking forward more videos like that .
Ps . you must enjoyed in the beginning the the demolition part loughing on a lot.
👏🤗👍
Level: Genius!
Love that build ❤️
Now I know how to make a spot welder I've never needed or will need! Thanks guys! Great vid
Я чет сразу хотел чего-то съумничать ,но со временем желание отпало) Браво!
Totally awesome video. One of the best I've seen in a while. Amen
No negative comments. I must say I have no idea when I would ever use this but I've enjoyed is built so much. What a piece of cool tool you have created. Congrats man
Esto es una de las cosas más geniales que he visto en mi vida.... que gran construcción!!! Felicitaciones!!!
Buenas Franco y para que sirve se relay que coloca junto al forzador y el trafo
Fuses and temperature fuses for safety would be also a good idea.
Awesome built and looks too quality and professional
You did an amazing job. 👏
@3:18 Do drill these in the reverse (as compared to the order done in the video). That way, the smaller forstner bit self-aligns with the center dimple left by the larger forstner bit.
Nice Idea, definitly one of the top 3 things I have currently seen to be build out of a microwave.
What are the other 2?
Hey what are the other two?😠
@@psi4262 Tesla Coil and high voltage traveling arc.
Beware of the ceramic insulator made with Beryllium. If you break it and breathe in the dust, you can get BERYLLIOSIS... a nasty incurable disease that screws up your lungs.... look it up.
Besides that, the capacitors in a microwave can possibly store power for years... enough to send you to the hospital, damage your heart, or put you 6 feet in the ground if your unlucky.
"Totally Handy" . . Is a serious understatement of your skills. Excellent job!
Simply amazing
Nice work how you create
What a nice, clean, professional build.
perfect job. you should use a cable gland or you power cable will be cutted in no time by the sheet metal....
Great job thanks for sharing, nice video and step by step. Overall I will give you 100% . But I thought initially is easy to do it - you make it look easy. Well done
You are amazing, you are awesome, you are an icon, Bravo Chef
Salut from 🇲🇦

I have no need of a spot welder but I really want to try this. Awesome video!
Really nice job you did there!!
I just realized im the type of guy who will be amazed by this and go out and buy a spot welder even though i dont need a spot welder
Caracas, que máquina de solda legal, parece até que é de linha de montagem.
Hi hope i can get the list of all the parts u used here
I am quite amazed ad cant help but be interested to try this project
Helloo for new video every day click to light bulb!
Genius 😁 Thanks for sharing 🙂
Totally Handy, you do nice work!
I’ve seen this project for years, definitely going to be making it this year, thanks and looks great! 👍
Make a video of how you do it. This guy just made his so over the top perfect. Just a idea. Also stay safe. God bless.
“How to build a fire hazard out of a transformer” is what this should be called.
Sweet crimp work, looks completely safe...
Wow. That's the coolest. Dude got skills.
It is nice to see it done so easily.. and to remember that you have an old microwave as well.
What he doesn't tell you is that you will need a proper workshop and electrical knowledge to build it. If you don't have them... enjoy the video and move on
The build is simple and everything he did you can do with hand tools stop being lazy
@@jimmytesta1454 he did not mention that the electronical components in a microwave could kill you or cause heavy harm. Dont work on a microwave if you dont know much about electrical safety or electrics in general!
@@GrossStadtAdler no, it's fine. just lick your fingers and stick them right into all of the electrical connections. that's what i always do.
@@GrossStadtAdler, bullshit. You'll get a shock but lethal... not unless plugged in. This isn't 1984 anymore
Great build made really well 👍 I have to mention the use of the nail gun whilst clamping the wood between your fingers. If you hit a knot or a nail it can bend through the side and go straight through your finger or thumb. Seen it happening plenty of times so please be careful and use a clamp because pulling a ring shank nail out is incredibly uncomfortable 🙃 Or you have to cut it free, go to hospital and feel like a plonker for wasting their time... 🤦♂️
I've done it, and was lucky it didn't go through the knuckle on my thumb.
What a good job.. thanks for this excellent video.
Very nice work on the finished product.
Very professional and clean building. There is only one down side and it may need improvement: Crimping the cable terminals/cable lugs to the black cable ends is not a good idea due to the high current passing through, so the electric contact between terminals and black cable may fail. Those terminals or Cable Lugs should be soldered (Not crimped) to the Cable Ends by using a torch and a soldering wire.
Отличненько, благодарю за подробную сборку
шляпа, так, на поделки сойдёт. по факту в районе сварки дикий пережёг металла.
@@Krik.. это нужно больше витков толстого провода делать?
@@vOLEGoff не в этом дело. надо увеличить давление на контактную группу и соединяемые детали, но при этом уменьшить время и увеличить мощность разряда. т.е., это совсем другая конструкция и устройство контактной сварки. Вы же видели, как собирают кузова автомобилей? прижим, фиксация, короткий мощный импульсный разряд. в этой самоделке ничего этого нет и хоть сколько балуйся с количеством витков на вторичке - она не будет работать подобно фабричной. здесь слишком растянут процесс сварки, поэтому он ближе к кузнечной.
@@baltasavr здесь есть видео постройки контактной сварки на основе транса от микроволновки, в котором описываются все нюансы, от выбора проводов до состава металла, из которого выточены контакты. ну, и сделана та установка совершенно на другом уровне, хотя тоже не без изъянов.
Для этой штуки нужен ещё латр и водяное охлаждение для электродов, и использовать для пайки а не сварки!!!
Wow! This is cool! It's cool color - orange!
Muito bom mesmo !
Meus parabéns 👏👏👏👏👏👏👏
wow. so easy to watch but so much skill went into this 👍🏻
Genial, parabéns!
Esta muy bien acabado. Un gran trabajo 👏 💪 👍
Meticulous to detail resulting in a great looking product.
Would like to know what gauge of cable you used plus where did you get the copper bar.
Great video!
👍 Очень красиво и аккуратно.
У меня только один вопрос. На 7:32 чем сварщик нажимал на кнопку? 🤔
Как в старом анекдоте: "А пальчики то - вот!" 😁
Только хотел это написать. Вопрос остаётся открытым.
Кнопку нужно нажать второй раз, чтобы отключить
Very nice! I would only suggest to use that torch to solder those large eyelet connectors rather than squishing them with pliers. It's the next best thing if you don't have the proper crimping tool laying around. But good job!
hello friend, if u don't mind could pls share the size & length for the copper round rod bar. thanks...Congrats for the excellent job.
That's a hell of an effort from just one part of a microwave!!!
Наслаждался пока смотрел. Супер!
I hope if you mention relay specification and wires diagram of the connections
Badass video. Cheers!
Yes, this would work. But I would recommend using some kind of current-limiting on the primary side of the transformer.
Te olvidaste demostrar las piezas a la que va que explican los diferentes voltajes y el esquema Cómo van Unidos correctamente todo para no causar un cortocircuito
Your a star bud! Great work.
ur work is so clean 🔥👍🏼
Very nice project and built extremely well, the only not so good point was no grommet or clamp around the supply cable at the case :) Apart from that its great and I might make one myself
A fuse might come in handy, too
Doubt it
Is there a diagram of the wiring? I have 3 microwaves I've saved for random projects like this! I need one of these! Great video
