I made mine last year and the duty cycle seems to be all day long I used 5 MOT in series with 8awg wire with 8 turns on all the sec windings and it works like a charm although the voltage is a bit low 30v it actually welds like a champ in case you are wondering it outputs around 200amps
I am NOT an electrician or something like that!! Watching this TUTORIAL makes me feel like I could become an electrician. WELL - THOUGH & PREPARED => WORK!! T-H-A-N-K-S 4 the AMOUNT of TIME spent on this! You should REALLY consider RE-UPLOADING this TUTORIAL in/auf DEUTSCH😅
I wish my professors in electrical engineering had been as articulate and concise as you. Thank you for taking the time to deconstruct these systems into their basic, first-principles components and concepts!
+OTL Productions I wish EXACTLY the same thing too! At least some of them were decent enough so by paying attention, all this stuff here makes sense, instead of trying to learn it now.
very good command of english for a not native speaker, solid theoric knownledge of electronics, good video making skills, and bit of humor. you are the man, man! :-) Grusse aus Italien
I'm in agreeance. However with todays computer skills it is not difficult to translate English into just about every common dialect spoken on the planet today! If I could transport back in time to when this video was made I would tell all of you that BITCOIN is where all your spare money should be invested! Buy as much as possible. As of today, Bitcoin sells for $70,000 per Bitcoin! Imagine a $1,000 investment 10 years ago what you would have today in 2024?
This literally answered every single question I had about the mechanisms by which transformers operate, in a remarkably well-structured format demonstrating a thorough understanding of the subject matter, making for the most time-efficient educational video I have ever seen in my life. Outstanding channel. I have never subscribed to anyone so fast before. This man is a veritable genius.
Thank you. I think that I'm very fortunate to live in a time when I can watch teachers and researchers do their work like this. It is a very personal experience. Thank you again.
I enjoy watching your videos and experiments. Way over my head and too late to learn at 72 years old. I was a welder for 40 years and really enjoyed what I learned while welding. Now I have a couple of welding machines that I need to repair and was trying to see if I could gain any information on UA-cam. It would have been nice to learn the electrical side of the machines I have used. Keep up the great work and teachings, much appreciated Sir. Paul Greenlee
Though i am a doctor by proffession yet i have great love for electronics and respect for the geniuses who have shown what human mind is capable of. Your video has been a great help to further my understanding oc transformers. Thank you!!
I've been an electrician for over 30yrs. I was apprentice of the year for my class and I have to say THANK YOU. Its been way too long since I've studied electricity. I knew there was a good reason I subscribed.
Being an engineer n enthusiastic of "how stuff works", I have bee watching electrical n mechanical videos on you tube since 2012- Today i stumbled upon best video i ever watched, which gave me great deal of knowledge n information. Must admit being good in academic n practical, i had overvalued myself. I m down on earth after watching n listening to sound technical knowledge from this video! Thx not only for uploading it, but reveling me how practical n knowledgeable a person can be-
I could write a lengthy piece detailing the various ways you impress with your videos, but I'll say this simple sentence, with deep & profound meaning behind it: You Sir, are an asset to a world of hungry minds... Thank you! From Joseph in Hudson Falls, New York, USA. 😎👍
Wow. So impressive. I am quarter German and I am sure I had the same monotone voice when I explained things to people as well. I am retired now but people commented about this to me when I worked and I realized I was doing it intuitively because it’s the most efficient way to teach someone. Being and acting like a clown or following like a sheep makes you popular but you don’t achieve anything. They called me a genius so many times I was sick of hearing it. I am sure he also has a very good sense of hummer as well. I feel like giving this guy a job not money. Sure it was not perfect and some depressed people will pick on the small cracks in his explanations but this kid presented a brilliant summary with virtually nothing. Thank you so much for your efforts.
I could listen to TPAA all day. I love how he sounds so casually brilliant. He's like this regular guy that you went to high school with, who also just happens to be an actual mad scientist. It's awesome.
Thank you so much for the very easy to follow explanations you've assembled in this video. I have found my learning ability is somewhat different than typical students and thus is why traditional schools heald not much for me.Primarily I'd say my focus was not all there in the classroom most of the time and I stopped going to school around 16 years old and began working 60 hours a week learning air cooled Volkswagen repair and service during the data and delivering pizza in the evening. A couple years later,I took the GED equivalency test out of curiosity to determine if I was stupid or was something else hindering my classroom distractions. I scored near perfect in all areas of the tests. One part that surprised me was the math portion. I had no previous schooling in the subject of algebra yet through the deduction process and common sense I scored well enough to pass! We all know that the older style GED had multiple choice to choose the correct answer from so, weeding out the obsurd incorrect answers made the percentages increase of getting the correct answer! I don't think I have ADHD or other type of condition except possibly Idiot Sevant? Ashburgers Syndrome? I did have a challenging home life without knowing my biological father.I am the youngest of 3 kids and brother and sister knew our father and are both extremely bright and successful in this world. To sum this up, your style of educating here in this video makes it much easier for me to retain what has been explained proving to me that youtube style education is a terrific source for anybody looking to further their education. My curiosity is what drives me to absorb hours of this and a few other fields of study daily. I couldn't tell you fact one about professional sports but anything automobile related to servicing and repair I am more than likely familiar with it. I have become very profecient in BLDC motor and controller building (thank you UA-cam!) and there's an inner connection this video has to that field. Spot welding is crucial when building Lithium Ion multi-cell battery packs. Even Ni=Mi batteries use spot welding to achieve the best adhesion of nickle tabs to physical batteries and the outcome is the cleanest most compact batteries available today.
As usual, I only understood about half of the info you presented but I sure learned a lot. Reminds me of the old adage about drinking from a fire hose. I keep going back to videos that I've already seen and learn more each time. Thanks!
Love your work ! I have an Electronic Engineering degree from 30 years ago, but I find your exceptional clarity of explanations wonderful for clearing the cobwebs away from the long dis-used magnetic theory stored in my head from way back then :) Ive mainly been a "Digitologist" in my career, working with Microcontrollers, PowerFets and embedded systems (EFI, Robot ESC's etc) so to see you working in the power electronic/electrical realm is excellent ! ...aaand. funnily enough, just a little while ago, I bought a modern DC Inverter Tig (and Plasma cutter) and taught myself to TIG weld (through youtube videos of course).. and I would *love to upgrade it to be able to do AC for Aluminium. Like you, I cant quite swallow the extra $600 (Australian) more than the DC machines just to do AC for some occasional Aluminium welding.. ... so If you are planning on trying to come up with some form of add-on micro-controller board to be able to generate the wave-forms (Frequency, Mark/Space ratio (cleaning action), Pulse Rate, Ramp up and Down, and external control (pedal, finger pressure trigger) etc, required to make a DC welder into an AC one, then I'm with you 100%. Ive already joined your Patreon campaign, If theres else I might be able to help things along with, let me know.... ...If you think its possible to microprocessor control the DC Welder electronics without requiring major PowerDrive component replacement, then maybe a Kickstarter project to develop an Open-source modulator add on board would garner some support to help development along ?.. ..In any case, keep on with the videos, theyre great ! Thank you ! :)
SpockieTech Hey first of all: Thank you for your support! It's great to known that I have obviously found a topic here that is "right down your alley") If I can find a reasonable way to convert the DC welder, then I indeed might think about a kickstarter campaign. The biggest problem with that will however be that there are so many different types and brands of machines that it will not be possible to create a module that will simply "fit" inside any given model. but we will see about that once I have done further research in that direction.
I know NOTHING about electronics, but still I watch these videos. I have almost no idea what you're talking about, but as long as you keep saying 'moss-fats' and I'll stay subscribed :)
I really liked this video, i just started my first electronics design job and now only design FPGA/analog stuff for the semiconductor test industry. now I finally got the money to do cool projects like this.
What a brilliant video! Clear, concise and no jibber-jabber. I understand my Welder better because of this video. Perhaps I can get it working! Thank you very much!
Excellent lesson, you are an outstanding teacher, remind me of Salman khan. You know how to explain things that seem difficult when explained by 99% of teachers and engineers. I hope you make lots of videos experimenting with different electronic devices. Thank you, keep it up
to the sound of evil buzzing at 50Hz: "as you can see, we are at an output power of roughly - oh wait, my Fluke is melting" great vid and perfect demonstration of shunting
For this application a current clamp would be very very very advisable . Btw , personaly i have great respect for classic welding machines , if you don;t abuse them they will last millenia . Perfect for post apocalyptic home use .
Fascinating stuff. Its much easier to learn this stuff from such a concise format as these well done videos. Plus this generally isn't the kind of knowledge you run into outside of an electrical engineering degree by the sounds of it.
I love these experimental setups you used to do. That reminds me.... I've got to get my dummy load designed. .. should keep me busy for a few days of lockdown.
I have a feeling some of my tutorials helped you disassemble your transformer :). Well done, interesting video. I appreciate a thorough explanation that is not too technical. Great content.
I have one of those welders, and added a 110mm 220VAC fan on the rear panel to cool it, which helped a lot with increasing duty cycle from it's original 2 minutes per 15 minutes to around 5 minutes per 15 minutes. It keeps the core cool, even if the stray magnetic field when the arc strikes stops the fan dead while welding.
I am NOT an electrician or something like that!! Watching this TUTORIAL makes me feel like I could become an electrician. WELL - THOUGH & PREPARED => WORK!! T-H-A-N-K-S 4 the AMOUNT of TIME spent on this! You should REALLY consider RE-UPLOADING this TUTORIAL in/auf DEUTSCH😅
Well another superb video here... I wish I had such a good teacher in my earlier years... Can't wait to get more of these incredibly informative videos. Thank you for all your time and efforts at making these tricky subjects so clear and understandable by the masses ! If only I had s few dollar to spare, I'd be glad to help you build your TIG devices from spare parts... I'll try to play lottery...
DJSolitone Thank you :). Your "mental" support is just as important. If it wasn't for faithfull viewers like you guys out there, I would have stopped making videos a long time ago. Even if youtube was a goldmine...
Brilliant. Good science and cleverness. Spend much time in a factory? Say as a Millwright or Electrician? I feel like I know you. Writing in 2018, this style was really fun. There is value in that.
A tip for cleaning a really dirty electronic part is to use a pressure washer. After a few day it can be powered up again one it is completely dry. This applies to old television sets, old radios etc.
Du erklärst das besser als unser TECH Lehrer :D Bin jetzt E2 und auf nem Beruflichen Gymnasium im Fachbereich Datenverarbeitungstechnik und unser Lehrer bringt das so langweilig rüber. Also echt gut und interessant gemacht :). LG Blackbacklp
actually there is another reason the transformer heated up so quickly. during normal usage the cables, clamp, clamp ground connection and the wire electrodes have a lot more resistance probably 10x more than the two short fat wires you bolted to the outputs, which of course caused more than the 140 max amps that the transformer is rated for. comparing the two fat wires to the secondary wires shows that difference. also most welders are sole with 20% duty cycle.apart from my above comment, I think I agree with all the good compliments about your videos. excellent understanding of the subject and very clear and precise explanations. thanks for sharing. I am looking forward to the "reverse engineering" video of the inverter welder.
I built my own arc welder by rewinding the secondaries on some microwave oven transformers. I even d/c weld with it through an MDQ200A bridge rectifier. It works.
Thanks for an excellent video. AC/DC welders are fascinating and as you know fall into two main groups, the older being switched by SCR pairs and the newer ones with IGBT units. Hope you eventually get to look at both kinds and share your thoughts. The dummy coil in the back of all the SCR units I have seen is fascinating and seems to be a balance coil to save the SCR from damage when the field reverses. Look forward to future videos.
Very cool. Your explanations were a great brush up on transformers. I found the part on stray field transformers and coupling to be quite informative as I haven't thought about those in some time. I finally found my first mot to fashion a resistance welder for both batteries and general spot welding. I plan to also build a basic arc welder with a variac, but would like to start working on a couple switching designs soon. Thanks for the video.
Well I am here again... The spot welder turned out nice, but I have an interview coming up and was trying to find some good review on the PWM control design for switching DC welding. Any good resources?
I have been contemplating building a spot welder (for putting tabs on batteries) based on starting out with a salvaged microwave oven transformer, and viewing videos where this was done. I see "remove the magnetic shunts" and after viewing this video now I know why.
so i watched this video yesterday and i was thinking about how to build a inexpensive welder. the idea i have involves 4 mots. i had seen a video where a fellow glues two mots together and ran them at the same time on one primary. this may be the concept we need here. instructions are simple. cut them in half and take out the high voltage secondaries of two and completely gut the other two. in pairs of twos, glue or weld the two e cores together to make two double size mot transformers. im from the US so run in series for 240 or parallel in phase for 120 unless the primaries are already meant for 240 then run in parallel. im gonna do some exparimenting. cheers.
The simplest welding machine consists of two separate pieces of tin sheet stuck in a bucket of salty water. One sheet connects to the live wire, the other to the welding stick holder. The neutral is common. - Half a handful of salt is needed for 8-10 l of water. Dissolve the salt in hot water. - The conductor thickness should be 2.5 - 3.2 mm2 for 2.5 thick sticks. - If the fuse is tripped, add more water and avoid electric contact with the earth. - You can use a car battery box (with the internal walls pierced) instead of a bucket for power control. *Keep in mind that this machine should be operated very carefully because the live wire voltage is on the stick holder AND in the bucket.*
a little late on the scene, but I did always wander how my old buzz box really worked, and why it always conked out on me in the middle of a job. I did however upgrade to an inverter machine which is so much smoother than the old transformer. i do miss it though, I did keep hold of blue (my affectionate name for the transformer) with the hope of making a spot welder, but in the end I donated it to a friend who wanted to "get into" welding. I must say that although your knowledge of electronics far outweighs mine, I don't feel as confused as I thought I was after watching. thanks for explaining this machine and I hope you managed to build an AC/DC gtaw in the end.
I received a new einhell cen 150 euromaster tranformer welder. I want to replace the permanent cables, with ones that connect to the welder with a Dins connector. If I remove the cables how can I safely connect the internal cables to the Dins connectors on the inside pf the welder? Thank you in advance for any advice.
I'm simply in awe of your brilliant effort, delivery and genius! Yours are the most productive, inventive and knowledge packed videos on the entire internet and my appreciation for your effort can only be expressed in e-notation! 6.022 x 10^23. Keep up the great work!
Excellent as always. Your experiments and drawings are first class. Well done. I found your channel through a search for SMPS information and devoured your 5-video series on that subject. I was excited to hear that you planned more. Will you still complete that series? Please, oh please, say yes! I would particularly love to see the buck topology design tutorial. Thanks!
FlyingShotsman Yes I will continue the series sooner or later. But I will continue these practical projects first. You can also trust me with one thing: The videos about the welding inverters will basically be like episodes of the SMPS-tutorial. Those thing are (concerning their mode of operation) not to different from what you will find in an ATX power supply for example.
The Post Apocalyptic Inventor Not trying to be smartass, I know English is not your native language neither mine but I think what you tried to say was "sooner or later" ;) Thanks for another great video by the way.
uncensoredtr Thanks for the advice. In German the words "earlier" and "sooner" translate to exactly the same word. So things like that happen from time to time.
Great video on how it is broken down to the t.. Man I wonder how long it took u to set everthing up and how long it took u too learn all this .. I have too say u are one smart dude !! Keep up the good work and showing us how all this works !!
You have really great videos and you can think really well. Many hours of work must have gone into that. Thank you for the great material! I live near Hamburg and might need your help and advice with some projects I have in mind for the near future. Thank you!
"wow" so impressive ! I have to admit the majority of it seemed far beyond the scope of most UA-cam viewers comprehension myself included - but it was such a technological coaster ride I was literally dumbfound with amazement anyway the whole 9 - it would take years for me to understand it all but I do have appreciation for brilliance when I see it - Thank You From a far less convoluted point of view lol I will offer some potentially positive feedback that may help your ratings and hopefully enchant your financial success at least to some degree - that is to keep in mind makeup tutorials for example on this site get up to a million views in just 6 months - your videos are getting less then half that and my suggestion is to try and tone it down a bit - more specifically try and convey information to a much broader range of intellect - your communicating to us all to often as though we are AWS certified engineers or something of a similar caliber and most people of this nature find better things to do then look at You Tube videos in the first place - I've never welded in my life but I am very interested in it and have several home projects in mind for it - just not sure where to begin with getting a machine to start with I noticed your Calif T shirt - I was born there :) and still live in So Cal a good part of the year - I am dual residency now and I own a home in the Midwest surrounded by farmland as well - Iv'e vacationed in Germany - Cologne and Munster were some of my favorite towns and I still own the 18 piece German made silverware set I purchased at Woolworths in Frankfort - Actually I just stumbled into your video while researching my options for a first welding machine - the more I read the worse it gets Lol - I am confused I don't know what to get !!! - it's not as easy to understand as a Silverware set
This is EXTREMELY well done, a brilliant exposition in near-flawless English and nicely touched with colloquial bits of humour too. Few of my British colleagues could come close to matching it. The subject matter is not 'advanced' from the point of view of someone with a decent education in electrical engineering - these are fundamental concepts that you would be expected to study during an electrical apprenticeship or first-year degree material. It makes excellent revision or supplementary viewing for someone doing that. Iron cores, laminations, eddy currents, airgaps and magnetic flux are very, very familiar to anyone working in that field. But it's incredibly rare to hear it described so lucidly, a tour de force and very well done indeed. And, having said that, I have a degree in electronic engineering yet I didn't know about inrush current in transformers caused by remanence, so I'm going to have to read up on it. If you are familiar with the subject, that throwaway line about the unlikeliness of achieving magnetic saturation of air is priceless, an absolute gem. It's entirely clear that for the person who wrote this has an exceptional theoretical and practical understanding of the subject matter and the physics involved.
i have a 3 phase 1 KW winding . i like to make one my primary the other 2 my secondary. i not been brave enough to wire up put 120 volts through first winding to see what volts come out the 2 other windings. i not sure i get a response i am interested
New video about welding machines is now online: ua-cam.com/video/6Gx9cBPrjAs/v-deo.html

By far the best, most educational video on electrickary. Well Done
SOmehow I prefer your videos even more than those other super high budget youtubers
Thanks for showing the dusting with the compressor, that was super satisfying.
That's the only thing you learn from this video , Lol - you're a genius man
ASTONISHED BY THE QUALITY OF YOUR VIDEO :))) Best video I've seen on YT in the last years. I'm visiting your Patreon site now.
Thanks for your time, money and effort into this piece of work.
Your videos are great, I enjoy listening to you speak. Very concise
I went to school for the wrong thing every time I listen to these videos I get excited to learn more. Should have been a engineer.

It would be terrific to have someone like you as a teacher at our school!
Great video.
23:50 thanks for showing this picture it helps me to understand the mystery of shunt plats :)
Crisp and easy explanation, that electrical students can understand well. Good job....
Like the coverage of things we take for granted, transformers are more than step up, step down and isolation.
Fantastische Video! Große Lektion in Induktivität, Elektrotechnik und Transformatoren.
I have one of those welders, and added a 110mm 220VAC fan on the rear panel to cool it, which helped a lot with increasing duty cycle from it's original 2 minutes per 15 minutes to around 5 minutes per 15 minutes. It keeps the core cool, even if the stray magnetic field when the arc strikes stops the fan dead while welding.
I am NOT an electrician or something like that!! Watching this TUTORIAL makes me feel like I could become an electrician. WELL - THOUGH & PREPARED => WORK!! T-H-A-N-K-S 4 the AMOUNT of TIME spent on this! You should REALLY consider RE-UPLOADING this TUTORIAL in/auf DEUTSCH😅
اقسم بالله اني احببتك واحببت قناتك .... عن جد انت ممتاز ...very very good ....thanks
I wish i understood this better than i do, but great anyway. I enjoy your videos, and hope to learn from your also.
Well another superb video here... I wish I had such a good teacher in my earlier years... Can't wait to get more of these incredibly informative videos. Thank you for all your time and efforts at making these tricky subjects so clear and understandable by the masses ! If only I had s few dollar to spare, I'd be glad to help you build your TIG devices from spare parts... I'll try to play lottery...
DJSolitone Thank you :). Your "mental" support is just as important. If it wasn't for faithfull viewers like you guys out there, I would have stopped making videos a long time ago. Even if youtube was a goldmine...
Extremely thorough. Well done.
Great video. You have excellent teaching skills and a very professional voice.
Brilliant. Good science and cleverness. Spend much time in a factory? Say as a Millwright or Electrician? I feel like I know you.
Writing in 2018, this style was really fun. There is value in that.
thoroughly enjoyed your video, even speaking in your second language you are a better teacher than my professors lol
So well explained!! I wish my university teachers would have been only a fraction as good as teachers as your videos!
A tip for cleaning a really dirty electronic part is to use a pressure washer. After a few day it can be powered up again one it is completely dry. This applies to old television sets, old radios etc.
Du erklärst das besser als unser TECH Lehrer :D Bin jetzt E2 und auf nem Beruflichen Gymnasium im Fachbereich Datenverarbeitungstechnik und unser Lehrer bringt das so langweilig rüber.
Also echt gut und interessant gemacht :).

actually there is another reason the transformer heated up so quickly. during normal usage the cables, clamp, clamp ground connection and the wire electrodes have a lot more resistance probably 10x more than the two short fat wires you bolted to the outputs, which of course caused more than the 140 max amps that the transformer is rated for. comparing the two fat wires to the secondary wires shows that difference. also most welders are sole with 20% duty cycle.apart from my above comment, I think I agree with all the good compliments about your videos. excellent understanding of the subject and very clear and precise explanations. thanks for sharing. I am looking forward to the "reverse engineering" video of the inverter welder.
I built my own arc welder by rewinding the secondaries on some microwave oven transformers. I even d/c weld with it through an MDQ200A bridge rectifier. It works.
You Sir are a GOD, what is it like walking around us intellectual mortals?
Thanks for an excellent video. AC/DC welders are fascinating and as you know fall into two main groups, the older being switched by SCR pairs and the newer ones with IGBT units. Hope you eventually get to look at both kinds and share your thoughts. The dummy coil in the back of all the SCR units I have seen is fascinating and seems to be a balance coil to save the SCR from damage when the field reverses. Look forward to future videos.
Very cool. Your explanations were a great brush up on transformers. I found the part on stray field transformers and coupling to be quite informative as I haven't thought about those in some time. I finally found my first mot to fashion a resistance welder for both batteries and general spot welding. I plan to also build a basic arc welder with a variac, but would like to start working on a couple switching designs soon. Thanks for the video.
Well I am here again... The spot welder turned out nice, but I have an interview coming up and was trying to find some good review on the PWM control design for switching DC welding. Any good resources?
I thoroughly enjoy your videos. Very educational. Keep them coming.
Only watched 2 minutes and I'm already subscribing.
Great explanation. The genius man you are showing respect must be Charles Proteus Steinmentz.
You videos are fun and educative thanks alot 💕
Extremely good and clear output, as always! :)
I have been contemplating building a spot welder (for putting tabs on batteries) based on starting out with a salvaged microwave oven transformer, and viewing videos where this was done. I see "remove the magnetic shunts" and after viewing this video now I know why.
Excellent detail in practical and theoretical regards. Thanks for sharing!
Wicked cool, u are my favorite mad scientist as of now🎆🎆🎆
Great explanation! The only thing missing was the equivalent magnetic circuit.
Amazing video dude, regards from argentina.
nice explanations, and good discipline in creating this tutorial
Very good video, as always very educational with explaining everything in details with examples. :)
so i watched this video yesterday and i was thinking about how to build a inexpensive welder. the idea i have involves 4 mots. i had seen a video where a fellow glues two mots together and ran them at the same time on one primary. this may be the concept we need here. instructions are simple. cut them in half and take out the high voltage secondaries of two and completely gut the other two. in pairs of twos, glue or weld the two e cores together to make two double size mot transformers. im from the US so run in series for 240 or parallel in phase for 120 unless the primaries are already meant for 240 then run in parallel. im gonna do some exparimenting. cheers.
awsom german, good english too,, very very smart,, please show how to fix welders,, 5 stars mate
very detailed and informational explanation, thank you
The simplest welding machine consists of two separate pieces of tin sheet stuck in a bucket of salty water. One sheet connects to the live wire, the other to the welding stick holder. The neutral is common.
- Half a handful of salt is needed for 8-10 l of water. Dissolve the salt in hot water.
- The conductor thickness should be 2.5 - 3.2 mm2 for 2.5 thick sticks.
- If the fuse is tripped, add more water and avoid electric contact with the earth.
- You can use a car battery box (with the internal walls pierced) instead of a bucket for power control.
*Keep in mind that this machine should be operated very carefully because the live wire voltage is on the stick holder AND in the bucket.*
Loved your video! Always neat to learn new things about welding.
a little late on the scene, but I did always wander how my old buzz box really worked, and why it always conked out on me in the middle of a job. I did however upgrade to an inverter machine which is so much smoother than the old transformer. i do miss it though, I did keep hold of blue (my affectionate name for the transformer) with the hope of making a spot welder, but in the end I donated it to a friend who wanted to "get into" welding. I must say that although your knowledge of electronics far outweighs mine, I don't feel as confused as I thought I was after watching. thanks for explaining this machine and I hope you managed to build an AC/DC gtaw in the end.
I received a new einhell cen 150 euromaster tranformer welder. I want to replace the permanent cables, with ones that connect to the welder with a Dins connector. If I remove the cables how can I safely connect the internal cables to the Dins connectors on the inside pf the welder? Thank you in advance for any advice.
Damn homie let's get back to refurbishing old vices, I feel like I did when taking a college classes I didn't understand..lol
The amount of knowledge I'd need to even begin to understand what's being said here would probably cost tens of thousands from a university.
I'm simply in awe of your brilliant effort, delivery and genius! Yours are the most productive, inventive and knowledge packed videos on the entire internet and my appreciation for your effort can only be expressed in e-notation! 6.022 x 10^23. Keep up the great work!
Wonderful Video! I will donate when able. Thank you for the excellent videos!
Excellent as always. Your experiments and drawings are first class. Well done.
I found your channel through a search for SMPS information and devoured your 5-video series on that subject. I was excited to hear that you planned more. Will you still complete that series? Please, oh please, say yes! I would particularly love to see the buck topology design tutorial. Thanks!
FlyingShotsman Yes I will continue the series sooner or later. But I will continue these practical projects first. You can also trust me with one thing: The videos about the welding inverters will basically be like episodes of the SMPS-tutorial. Those thing are (concerning their mode of operation) not to different from what you will find in an ATX power supply for example.
The Post Apocalyptic Inventor Not trying to be smartass, I know English is not your native language neither mine but I think what you tried to say was "sooner or later" ;)
Thanks for another great video by the way.
uncensoredtr Thanks for the advice. In German the words "earlier" and "sooner" translate to exactly the same word. So things like that happen from time to time.
Great video on how it is broken down to the t.. Man I wonder how long it took u to set everthing up and how long it took u too learn all this .. I have too say u are one smart dude !! Keep up the good work and showing us how all this works !!
You have really great videos and you can think really well. Many hours of work must have gone into that. Thank you for the great material! I live near Hamburg and might need your help and advice with some projects I have in mind for the near future. Thank you!
"wow" so impressive ! I have to admit the majority of it seemed far beyond the scope of most UA-cam viewers comprehension myself included - but it was such a technological coaster ride I was literally dumbfound with amazement anyway the whole 9 - it would take years for me to understand it all but I do have appreciation for brilliance when I see it - Thank You
From a far less convoluted point of view lol I will offer some potentially positive feedback that may help your ratings and hopefully enchant your financial success at least to some degree - that is to keep in mind makeup tutorials for example on this site get up to a million views in just 6 months - your videos are getting less then half that and my suggestion is to try and tone it down a bit - more specifically try and convey information to a much broader range of intellect - your communicating to us all to often as though we are AWS certified engineers or something of a similar caliber and most people of this nature find better things to do then look at You Tube videos in the first place - I've never welded in my life but I am very interested in it and have several home projects in mind for it - just not sure where to begin with getting a machine to start with
I noticed your Calif T shirt - I was born there :) and still live in So Cal a good part of the year - I am dual residency now and I own a home in the Midwest surrounded by farmland as well - Iv'e vacationed in Germany - Cologne and Munster were some of my favorite towns and I still own the 18 piece German made silverware set I purchased at Woolworths in Frankfort - Actually I just stumbled into your video while researching my options for a first welding machine - the more I read the worse it gets Lol - I am confused I don't know what to get !!! - it's not as easy to understand as a Silverware set
This is EXTREMELY well done, a brilliant exposition in near-flawless English and nicely touched with colloquial bits of humour too. Few of my British colleagues could come close to matching it.
The subject matter is not 'advanced' from the point of view of someone with a decent education in electrical engineering - these are fundamental concepts that you would be expected to study during an electrical apprenticeship or first-year degree material. It makes excellent revision or supplementary viewing for someone doing that. Iron cores, laminations, eddy currents, airgaps and magnetic flux are very, very familiar to anyone working in that field. But it's incredibly rare to hear it described so lucidly, a tour de force and very well done indeed.
And, having said that, I have a degree in electronic engineering yet I didn't know about inrush current in transformers caused by remanence, so I'm going to have to read up on it.
If you are familiar with the subject, that throwaway line about the unlikeliness of achieving magnetic saturation of air is priceless, an absolute gem. It's entirely clear that for the person who wrote this has an exceptional theoretical and practical understanding of the subject matter and the physics involved.
wow my head is spinning Great depth!
Your the champ! another excellent vid!
Cheers from Toronto
I'd love to see some welding training videos from you , as a maker
This is so great and so inspiring. Thanks for doing this.
Great video, very nicely explained.
i have a 3 phase 1 KW winding . i like to make one my primary the other 2 my secondary. i not been brave enough to wire up put 120 volts through first winding to see what volts come out the 2 other windings. i not sure i get a response i am interested
Great video! Hope to see the next one soon!
Very informative. Im impressed. Well done!
Damn I love you germans !! And all the wonderful tools that comes out of your country !!
Thanks for the good explanation. Thank you very much
Quite decent content. Thank you.
You remind me of Egon Spengler. The difference is that Egon speaks about fictional science but you speak of real science. :-)
Extraordinary video. Thanks!
i hope you can make a lot of video in the future. thanks so much
Fantastic and well explained video! I learned a lot.
