Thanks for over 250,000 views! I receive a lot of questions about the construction of this type of welders and how to do it the easiest way. Currently, such drivers are ready on AliExpress. Look for the "spot welder controller". It is enough to connect the transformer and spot welder is ready. Good luck in your constructions!
I don't know what I'm more impressed with the spot welder or the box that in cases the spot welder. Have you ever thought of starting a career in making birdhouses for the Rich and famous??
You are a genius and have some serious talent. I got an AA in electronics so I knew exactly what you were doing but it's how you executed the plan that is beyond impresive. Great work
There have been a number of these I've seen people build over years. Nothing has been this good looking, nor have I seen someone spend so much delicate time into detail. You got yourself a sub when I saw you make the circuit board. :]
I would give him an A- xD The project it self is very awesome, but for an A+ he should better watch out for battery safty, using such batterys with broken sleeves (on the minus pole), is in my eays an no go and on a longterm view a safty issue, as you can't put on a new sleever afterwards...
The point of DIY is to make it available to all who want to build it. Here the build is so good but no Schematics, code etc is provided. Hence not a DIY project. Personal project sure but NOT DIY.
are these just stripped solid-core copper wires as electrodes or tungsten copper ones? the ones i had need to be sharpened and cleaned after 5 welds everytime
Although I would have loved to have seen 2mm thick CF boards with an aluminum base and a bit more scaled down.. this was the best DIY spot weld tutorial I've seen. You know what you're doing, brother. Good work.
Thanks! I made this tool as my engineering exam. Due to the law in my country, I will not be able to publish the code and the PCB project for about half a year. However, the program is simple, I think that every amateur computer scientist will create a program for you within 10 minutes. If you only want a time regulation without a display, you can use the 555 Timer and SSR instead of Arduino
Holy shit! you just blew my mind I've never seen anybody make a circuit board by hand before! I have my own mechanical talents but would love be able to do that... thanks so much for sharing
What! A wooden box? Great project entrapped in a fire hazard case. He's got a lathe, a drill, and all sorts of good tools and he uses a fire hazard wooden box. Crazy.
This is a very nice project. BUT! You don't really show any schematics or how everything is wired or anything about the code. I don't see why you had to share this without providing any information.....
@Smattless I have almost no idea about electronics, yet I'm confident that from what I've seen in this video I could go out and repeat (a less beautiful) version of this. Would I have to look up more info? Yes of course. The people who would genuinely want to make this would be able to do so from what is presented here.
you do realize Scottie that the provision of schematics for any circuits you automatically incur legal liability for the negligence of the viewer? Plus it might be a prototype or a patented circuit? An inventor may need to rely on verbatim copies when they first began, the seasoned usually just needs an idea. In this case I found it better that the controller was not written up in detail, its a nice challenge of a puzzle when 75% of the solution is a given and 25% requires a little mental effort. It is how originality and creativity evolve in strides
@@TheKoodus You know nothing but people should be able to make it themselves from what is presented here. You are right about one thing, you know nothing.
Very impressive. The electronics has always baffled me...I don’t know what most of the people are even talking about in this thread. I understand welding, turning items on a lathe and building a simple box. I was curious why you were using a hand screwdriver with all the other tools you had available...then near the end the DeWalt drill/driver came out. Great video! Thanks for sharing.
Regardless of downvotes, this was helpful and clearly shows a knowledge of the required electronics. A PCB link that can be obtained from the usual retailers would be awesome!
Nice job on the project and extra points for making the circuit board. I made the same project and just need to put it in a nice box like you did. One of these days.
Is that SSR still working? I was thinking about using the same one but the rated current is no where near enough, I'm interested to know if it's still working, perhaps it can deal with it due to the pulse time.
The most relevant parts of the construction - The Box; Welding Arm & Power Source were beautifully put together. I'm personally getting a third party controller that can be driven by LiPo Cells or modified MOT as shown here, although it would have been useful if the Arduino code and/or PCB Layout were also posted ;) Well worthy of a sub and thumbs up tho!
Awesome spot welder! Just keep in mind that the chinese solid state relay you used is probably very under-rated. They say 25 amps, but contain a triac only capable of 16.
I would, and I am sure others would be more than happy to pay for the schematic, parts source and the circuit board. Or, if there is some reason why you do not want to release that information at least inform watchers that it an example only and no specifics will be provided. Please consider making these items available at whatever price you think is fair. I am sure you would have many people interested in purchasing these things from you. Thanks for your video.
Very cool and I like how you do your thing everyone is going to say how you could do something different or better, etc. that’s why I can make my own my way my money right!
RU-vidr creating a welder. RU-vidr: Let's make a complicated system of wires! Hands:ok done. Yt: make sure it can't catch on fire using all possible ways. Hands: good! Done. Yt: *MAKE IT OUT OF WOOD*
I have this thought ever since awhile now, but since you mention your gonna make a skate board so i might as well just tell you I have an old scooter motor which still work And i have plans on using and making an electric skate board, However i dont know what source of power should i use or how to drive it Im thinking om using tilt steering and using a power drill (without the motor) for acceleration so i can control the speed. Please tell me your thoughts
I think it'll be fine with just a short pulse duration with those 100 amps. Main thing he should worry about is cooling, but he seems to have got that covered.
I can't read french well enough to be sure but I think Alain has the correct answer - the SSR is in the primary side. You can see this clearly because it has flimsy mains wiring to it, not the huge black secondary wiring. You do need to downrate an SSR driving an inductive load (the transformer) but a microwave oven transformer is less than 1kW (4A at 250V, 9A at 110V) so its primary will burn out before the SSR does.
Most beautiful thing I've ever seen! The circuit board method was inspiring - truly. I would have sourced that part out - but watching it being built from scratch was amazing. The thing that scares me the most was the microwave transformer remodel. Not sure how safe that is. But what do I know. So what was the final cost ~?
Well done! Anyone asking for code shouldn’t be dealing with electronics at this high current anyway. This isn’t a beginner project! I just finished my newest welder with a triac driver instead of relay. Very happy with the results as those Amazon SSRs were crapping out on me quite frequently!
i made same welder,but im not sattisfied... poor welding even with warious time and current settings... my transformer is a bit small...can it be problem ?
Congrats, probably the only safer build I’ve seen in youtube. Still not safe for those that don’t know, he made that transform put out hundreds of amps. But this is one I would agree to replicate compared to a lot of the other ones I see with safety or design issues.Nice job, you’ve done your research that’s for sure. I’ve seen a lot of people make their own and how it’s made scares me for their life. Nice solid conductors to the weld points. It’s a cheaper knock off solid state rated for 25 amps I think, but should still handle 15 amps constant so for pulsing to the secondary so it’s good. Looks like you 4 winds of wire is about 4 to 6 gauge solid copper windings wire, the microwave transformer looked like a newer one so I would say it’s originally a 2.2Kv. With 4 volts out, my guessing your getting about 450 to 600 amps pulsed current on the secondary. Have you measured it with a clamp? I may be wrong since I am used to measuring MOT mods with 110V mains US and your using a 220V MOT. But are you running this on 220V or 110V? With the thick nickel plated iron corner joints on the 18650 cells I know these need at least 600 to 650 amps, or 500 amps at 4 to 6 pulses. You chose one of the better, easier ways for modding the MOT transformer. Again, did your research. Was that 10 AWG wire for the welding points? If I had to find something to change it would be the heat shrink wrap on the copper posts to a better thicker NTE high voltage wrap. And because of mains maybe isolation slots on the PCB before the transformers that I’m assuming are in series? You could have gone with an optical isolator and a triac, but most on a 120 volt mains will end up burning out the triac unless they learn to give more cooling time between welds. So again good choice of doing it differently then the cheaper route using a triac. I’m guessing one transformer is for the Arduino, and the other for the solid state relay? Then in the PCB you have V01, it that a voyage regulator for stable voltage to the Arduino? Or is it a something like a MOC3023? If not, might be good to add that for some isolation before the solid state relay.
I have a life. So why the comment. Oh, maybe because you realized this one is made better and done safer then the one you have since you claim yours is better? if it is then prove it, I don’t see you making a video of yours. A lot of people asked how it was made or the parts used, I thought I would help and point out some of the things used, maybe see if he would answer a few questions.
Why would hundreds of amps be dangerous ? There's only a few volts. Nobody gets electrocuted. The biggest danger would be from misconnecting the lithium cell (so the welding current passes through it instead of across the end cap).
@@GadgetReviewVideos It's not for your elaborate know it all bible. At no point i have said mine was better. I don't have to prove anything for the likes of you. It is you who wrote all kinds of 'improvements' it is you who is questioning his product. Mine is 60% more compact and does the same i said. So try to get a life whining little bitch.
