The voltage from the transformer I played with was 800VOLTS! after you remove the secondary, that risk is gone, but with the new windings you instead have a high current (amps). There you have a risk of an arc burn than can hurt your eyes. Please be careful, and if you try to weld use a welders helmet
@@stevehenry1 no high voltage can damage both your eyes and it can also electrocute you badly and the plasma arcs have a large amount of ultraviolet radiation.
@@stevehenry1 and not only that the voltage he uses is only 1 volt and at this voltage it is impossible to create arcs and this voltage can be used for only spot welding and not arc welding and so it is impossible to damage the eyes.
@@manashsaha2312 yeah if you want to arc weld connect 2 heavy duty drill baterys be careful tho the fuses will burn out I personally bypassed the fuses on mine after burning it and melt stuff with graphite rods lol
This style of high voltage wood burning project has killed at least 50 people in a particularly horrific and agonizing way. These videos never indicate how dangerous the project is.
Two additional hints: 1) It would be a good idea to solder the high current twisted connections, or get some of the various compounds used by electricians for protecting high current connections from oxidation. The bare copper will oxidize from the heat generated by I^^2 x R losses and eventually burn up. 2) The bridge rectifiers used in the battery charger/jump starter are too small, only good for 25 amps each. Each MOT can produce 100 amps at 12 volts. And when paralleling such rectifiers you need some resistance in series to prevent one rectifier from 'hogging' the current. A better choice here would be one big Schottky full wave rectifier rated for 200 amps.. All in all, a good video. Recycling MOTs is a great idea with much potential (maniacal laughter).
Safety is job number one, no doubt about it. And not only is high voltage dangerous, but so is high current. Think about the consequences of getting a finger ring or watch band acoss the high current, low potential. Or worse yet, a nose ring!!!!
Yes, It´s terrible. But not only the first one - all of them are dangerous because of no safety and verry poor kind of worf. I name it the Hot-Glue-Mafia.
Nice work. I've been seeing around these apartments a lot of microwaves getting thrown out. I figure.. I'm bored , retired and i've got a minor in engineering . Not electrical but i can fake that part cant i? Watch for a nationwide Power outage and remember me. I LIKE THAT SONG. Ill have to look it up. yes. THE VOLUME CONTROL WORKS BOTH WAYS PEOPLE. he isnt giving verbal instructions. mute it and listen to the voices like i sometimes do. I hope you've got a sense of humor dude. I get more humorless people with replys like this than you can even imagine. thanks for the video.
A nice hack when playing with these transformer is to take a tape and wrap over pliers on the handle in order not to receive a good jolt when working with power on. When the spark almost seems to “jump” it can actually be quite painful and sometimes result in loss of taste for some foods for a time. Also smell. A good hack is also to wear a nice work glove when connecting anything that is energized also a nice sized rubber shoe will help to insulate you from a electrical jolt. Remember to always use caution
Now, were did these awesome background sounds come from? I'm a psytran fan, but this has a more profound and epic feeling! Very good indeed! What's this called??
Hi i have a microwave transformer and secondary is removed and I'm using it as a step down transformer. But it get really hot during usage. Is it normal?
Yea there is actually, remember when he first hooked up the leads to the screws, well those screws were on one side of the box that was enclosing it, n from what I seen he burned right through that fucker..I’m mean correct me if I’m wrong
That ventilator, that fan, it has not the least use there, while the air cannot flow while the case is totally closed. A couple of airholes in the sides or best in the bottomplate around the transformer are needed for a fan to work. And the same in that last idea. That coolprofiles are not yet 5% used with the rectifiers so screwed that way. Not to the flat side but only making a lesser thermal contact to some little areas on the side of the ribs. Wich are also screwed because now neither side can allow convection while screwed on to the bottomplate with not even a little airgap. Keeping half of a cm distance (with some washers or so beneath them) would at least allow them to work. So rectifiers must be screwed on to the flat side of the profiles, in that slit that's made for screwing the component on the flat side for some thermal contactsurface. And with washers beneath it air at least cán flow around most of the surface of the ribs. Its airflów that provides heatdrainage. Without that the component is there for nothing, the same as with the incapsolated fan at the beginning
Ok do not ever use a MOT to make fractles. This is not new by any means and has killed many many people. It outputs 2000kv at around 200mah which is like 20x the needed amount to kill you at that voltage. If you do want to make this stuff use a flyback transformer. The issue with MOTs is they run at the same 60hrz frequency which works very well at jaring muscles like your heart. A flyback works at 30khrz to 40khrz
IN THE BEGINING OF THE VIDEO YOU SHOULD MAKE A FEW HOLES ON THE SIDE OF THE BOX SO WHEN USING THE FAN AIR CAN FLOW THRU THE HOLES AND OUT THE BOX BECAUSE THE WAY YOU HAVE IT IS NOT DOING MUCH.
Microwave transformers are terribly inefficient and overheat badly when powered up for any time. Also extremely dangerous to operate when the high voltage winding is left intact. All these "neat" projects are an accident waiting to happen!
Look at the timeline for 50 seconds. Note he/she/it is drilling towards his hand. Experienced people won’t do that. But what about a 13 yr old mind in a 21 year old body🧐🧐. They might drill and regret it
This will kill you instantly. I have watched it up to welding switcher and it drives me crazy. The microwave transformer has 10 000Volts with about 500mA. Connect several of them together use 240volt switch 7cm from the coil..... The sparking arch can jump up to 50cm to a wet grounded surface. That is absolutely lethal.
I chiseled out the secondary on one transformer in a hurry one winter as a waterpipe in the wall froze due to a cold snap and strong wind. Put a 1 turn secondary in it's place from an old jumper cable and clipping onto the tub spout and the toilet supply valve, thawed the pipe in the wall before it froze hard enough to break the pipe.
Dreadful music! No verbal or typed information. Tried using microwave transformers to save money on projects, but microwave transformers have such a bad temper when they get upset with someone tampering with them. Got one left, but too scared to plug it in, after the last one blew up nearly popping my ear drums. Have now ordered a pair of red/green colour blind correcting glasses.
Really? I Made spot welder machine with these transformers. It kinda worked but I wasn't happy about the result. I also tried to rewind the secondary to make a high current transformer but it get toooo hot I think i know why. But I didn't hear about these trans can blow up. It's too scary
Exposed and dangerous connections, measurements for voltage and current without load, connecting transformers in parallel, without explaining why the wires are connected in such way for primary part and secondary side, using a fan to blow or suck air from or into a box without a secondary port for air circulation, wiring by few twists on screws and not clamps, rings, connectors designed to make a good connection and without the need to apply solder, and so on. This must be some tricks for amateur electrician, assuming he will be alive after performing them, taking into consideration the various connectors of such microwave transformers, high frequency types... Did some connections as a kid, but now I would never do that knowing what I know and how dangerous can be... This kind of videos are using Darwin law, if you know what I mean...
Throwing together a bunch of phrases does not help anyone. You seem to have some relevant knowledge, why don’t you explain for the rest of us what you mean? Stop being a “twisty, condescending...” whatever and contribute!
@@tc8533 Why? This isn't their channel. Your safety is your responsibility and yours alone. If people are too dim to recognize possible fatal safety issues, cool. There's too many idiots on this rock in the first place. They pointed out safety issues, what you do with it is up to you.
Im not sure about the wire size but i know usually they have around 120 and 150 turns i have many of them and never had that problem. Good luck make sure the wire is very tight if you decide to fix it or is gonna vibrate.

Brother you handle that table saw well.. but your blade is way to high.. to help to err on the side of caution make your blade about an 1/8 or less above the top of your materials.. nice trick.. very handy.. thanks.
FFS don't do that!! They're there to prevent over current and avoid overheating of the windings. The last thing any of the projects in this video need is less safety.
I was gonna say something about having a saw blade protrude an inch or more above the workpiece, but thank goodness you beat me to the punch! Please do not look into laser w/remaining eye!!
spot welder failed because you actually need hardened copper for electrodes. helps a lot with better welds. also you are holding the spot welder on for too long. damaging the cells interior chem. 0.5sec's is max required.
@@BalkanHandyman i had the same problems when i built mine. i thought it was the low voltage or all other problems.. turns out it was my normal soft copper electrodes i used. tried tungsten. not advised. hardened copper now. and its perfect.
Is that fan sucking or blowing? and in either case, WHERE IS THE AIR EXHAUST OR INTAKE?? If the close-up of the labels was your concession to safety, it really should have been on the 1st demonstration where the HT winding was still intact.. Take great care folks.
Not enough windings looks like one and a half pet transformer you need more to get voltage up say 3 or 4 turns with 6mm cable that should spot weld better
Just wondering bro, do you have any schooling or any formal training. I’ve taught myself quite a bit through trial and error and reading books and along with a few YT videos..but I finally figured out what I’m passionate about (inventing, electronics/electrical engineering + woodworking) and I wondering what courses I should look into. If anyone would like to reply that would be most appreciated thanks.
@@fredmetcalf 1st rule of using a table saw, use bare hands to feel, and absolutely NO loose clothing, DON'T be distracted, and keep your eyes on the task at hand! Let's just make it through one task at a time by paying attention. Great video!
Another point-The blade should not project thru the wood no more than quarter inch.So if you should slip-you won't get as seriously cut.For the crosscuts your saw needs miter guage slots on its table and a miter guage.I treat using a table saw as serious as using the wood chipper!
Have you ever put a large horse shoe magnet over a Christmas light bulb? I did it in 67 an engineer from NSP saw it he didn't even say anything at all to me but everyone in my class thought it was kind of neat. I was eleven years old.
Potresti avere molta più corrente da un trasformatore solo, semplicemente mettendo 3 spire di cavo da 25 mmq e non 2 spire di cavo 3 x 2,5 mmq come hai fatto!
The first project : I wish I knew the steps he was going through. Which was the primary and secondary? Where was the cooling fan getting its air from? What was the liquid he was painting and what was the purpose?
secondary has the smaller gauge windings. backing soda (soda bicarbonate) and water creates the conductivity path. he needed to put intake holes in for a more efficient fan.
Don't try it. Many people have been killed doing this kind of wood burning using micro wave transformers. Never use the existing secondary coils of these transformers ,smash them out and re wind with heavy gauge wire in order to do sensible and safe projects like spot welding or battery charging
Hahaha! The last one was impressively smart for it's simplicity. Simple, but you had to think it! Thousand thumbs up man! I bow down to you respectfully for your ingenuity. Thanks for sharing.
don't try to solder anything resting on pliers - the metal of the pliers will soak the heat away and the job will take longer . Rest the part on a piece of scrapwood instead.
Can you design a transformer project that can destroy this music? Still watching. I just tore down a microwave today and this pops up. Sonebody at RU-vid must have seen me pricing new ones yesterday.
Won't point out what lots have already pointed out, but in the end, the battery charger at 16.9VDC RMS can harm the battery because it can charge to over 24 volts. Don't believe me ? ? ? ? Put a capacitor across the two outputs. make sure it's rated for more than 36 volts. Read your final voltage and you'll see 24.038 VDC. Also, WOW! You figured out how to burn wood. And your spot welder ? ? ? ? Geez! Cooking the hell out of those batteries.
High power transformer :) Get 12 gauge magnet wire and bend into 2 equal halves then use a drill and eye bolt to twist the wires. When done use this wire to rewrap the whole inside of transformer. When done wrapping ,,, cut inner wire connect inner wire to outer wire so you are left with 1 inner wire and 1 outer wire. Pulse this with a Bendini motor. Makes a great inverter when the transformer is hooked up to a plug ins strip. When wired up this way in the transformer it puts out MEGGA POWER. USE a small solar panel to run the motor. High Voltage.
They say its safe practice that when working with high voltage to always work with one hand behind your back so the path of electricity wont flow through your heart if contacted with a hand and grounded with the other. But what should also be said is you should always wear pants when working with high voltage as well. Baked beans and sausage are only good from a grill.. damn things like a lightening rod...
I'd rather have my finger nails ripped out by pliers or visit the dentist and have multiple fillings with no anesthetic than listen to this. Probably more enjoyable to watch a recording of yourself and a dominatrix shoving something where it doesn't belong while you scream than this.
.....you could obtain a better striking/holding arc, if the pressure (volts) was increased to 48 or so......done this and can weld with .25 inch 7018 or 60 series rods...
Lol you solder crimp terminals? That's like wearing a belt and suspenders. And you went through the trouble of doing that, but taped the fan connections. Hilarious

I would not charge a battery using the bit at the end. Seems like a good way to ruin your car battery. No voltage regulation occurs coming straight out of those rectifiers. At least include a series power resistor to allow the current to drop as the battery reaches full charge...
When I was a teenager, my father made a battery charger from a scavenged transformer and some rectifiers. The output voltage was about the same. He hooked it up to the battery in his car to charge it, but when he saw the vigorous boiling of the battery acid, realised the charging current was way too high. He panicked a little and disconnected the battery leads without turning it off first. The resulting hydrogen explosion destroyed the battery.

The fractal burn works best if you use a variac to gradually ramp up the current. I never needed more than 50% voltage to get a good pattern. More than that tended to produce similar results as you got, i.e. flash-vaporizing the conductive solution and generally impeding the burn. Using variac also helps avoid the problem of the transformer heating excessively. A "120 volt" MOT is really only good for 80 to 90 volts at most, a "240 volt" MOT is good for 160 to 180 volts at most. Beyond that, excessive current flows through the primary due to magnetic saturation of the core, and this power will be entirely wasted and dissipated as heat.
Another item of note: These xformers, designed to start ' under load ' / the primaries, are several turns, less than a 'normal' xformer, so be carefull, of leaving it plugged in, WITHOUT A LOAD.....
