So I actually finished work on Christmas Eve, but the video took 14 hours to upload, because of the horrible upload-speed at my parent's house :D. So it really is Christmas by now! So I wish all of you a a Merry Christmas and I hope that all of you are having a good time no matter if you're with friends and family or all by yourself, maybe in some dorm room somewhere. (I've had some of those Christmases myself). So my thoughts are especially with those of you who have to spend the holidays alone. One thing that always helped me to keep my spirits up, was to watch Al Bundy getting through his holidays all by himself (after his family had left him to eat at Denny's without him) :D kzbin.info/www/bejne/nXXYinxmicmSqNk (In better quality: www.dailymotion.com/video/x6a01rn)

[@gregh7457]

I would have thought you watch McGyver and not Married with children LOL

[@lilozwelder0478]

Merry Christmas and I praise you for repairing this beast of a transformer mig, what brand is it and by the way the wire feeder is supposed to be vertical not horizontal but you preference

[@christianandersen7458]

Merry Christmas from 3 phase, 230V at 50Hz in Dänemark :-)

[@CliveChamberlain946]

Merry Christmas from a Split-phase 240v 100A guy here in Canada! (supporter EEVblog KZbinrs List). Compared to the blue machine, wow! That unit kicks butt! I'm looking forward to the next video's to be sure!

[@dave1135]

The Post Apocalyptic Inventor theres no shame in labelling connections, ive been a auto technician for 35 years, and I STILL label or take cell phone pictures of connections, hoses, wires, and brackets/spacers.

[@tannin2249]

It was so good today to see a wonderful new TPAI in the classic style. I'm sure it takes ages to produce each one of these full-length, detailed TPAI gems - there is not just the work itself, but all that thought which goes into scripting, and hours worth of editing after that - but the results speak for themselves. I hadn't realised how much I have missed the real TPAI until watching this first new one in a very long time. If it takes many weeks to produce each work of this quality, so be it. It is always well worth the wait.

[@ruffmansavageveteran1345]

I started learning to MIG last week and remembered your videos about repairing welding machines.

[@TradeWorks_Construction]

You do some of the best informative commentary I've ever encountered on KZbin. The natural progression from one aspect to the next coupled with explaining components and sections that i naturally was already curious about all outlined with diagrams or drawings that are done to a professional standard, All of it is simply fantastic . I even find the extra tid-bits of historical changes made overtime or the extra time taken interesting in their own right and believe that info could vary well be extremely helpful to someone who may have a similar model or the same model of a different year as it's pretty rare for people to have the exact same identical product. Don't worry or stress much if a segment you're doing is turning out longer than you think it should. Many subscribers like myself enjoy learning about the "how" and "why" as much or more than the "what".

[@isidoromaich7226]

I love this kind of videos like in the old days, thank you and Merry Christmas!

[@MrAlFuture]

Isidoro Maich yup, i agree.

[@franganghi]

It was so clear! You have my admiration. You would be an amazing teacher in a technical school. Really. Have a nice holiday time!

[@mohabatkhanmalak5314]

franganghi , thats exactly what I thought! He would make a great tutor/lecturer at a technical school or university. I just saw his video and I am subscribing as I have a lot of interest in engineering.

[@mohabatkhanmalak5314]

Merry Xmass and best wishes for the new year. That old welder is quality, and you are right to bring it back with good modifications. What make is it?

[@Mohamed-jn4yr]

i wish you had an USB 3.0 output in your head n i had one in mine as well so i can stream all the knowledge you have .. i don't know how to thk u for sharing all these precious knowledge in ur videos . keep up the good work ☺

[@H.E.J.S.A.N]

I like your movies! For me, you are an archaeologist of forgotten electrical and electronic devices. With your enthusiasm, you bring them back to life using new solutions and technology. Bravo! ..and Merry Christmas!

[@darsonb904]

Honestly you have such a fantastic youtube channel! I came across you the other week and have been watching video after video. I am very grateful for all of the details you add into these videos which really helps with understanding the function of the machines / tools you are fixing. I have gained so much information from you and especially from your scrap yard episodes. As soon as lockdown is lifted here in the UK I will be heading to my local yard and trying to follow in your footsteps😊. So please continue your hardwork and I will be awaiting every upload!!!

[@gunfighterzero]

im an electrician in the US i find your videos fascinating. i had no idea your 220 used a neutral. we usually assume its 220 phase to phase like 220 in the US... i work at a 120 year old steel forge, you would love all the old stuff we still have. i took a motor off of a crane a few years ago that was dated 1919 and it still worked up until then

[@reduniverse0]

Nice drawings and explains ! If you would consider to add a diagram with the 3 phases waves (or a link to a video about it) it could be even brighter for those (like me) who need to see how it works from inside the inside. The help of 3 phases in rectifying electricity is so important... During my studying period in college I worked on a project in which I ordered a single phase inverter. This machine had the capability of supplying 3 phase and of course had PWM support. Might be interesting if it works for powerful machines like a welder...

[@ErikSandstrom]

As a mechanical engineering student I love marathon watching these videos. Super creative and informative

[@nferraro222]

In the US, a great deal of used 3-phase equipment goes directly to the scrap yard. My local yard has 3 giant MIG welders like this, a surface grinder, and a warehouse of other equipment.

[@TheRealCCSmith]

I was cleaning out my shop today and found a box of parts from printers, scanners, and a fax machine I think. If you need or want these parts I would be happy to mail them to you, as long as the postage isn't outrageous considering that I live in Texas.

[@levamento]

Ein großes Lob für Deine Arbeit! Ich schaue mir seit längerer Zeit auch Deine Videos an und tue dies in zunehmendem Maße, da Du immer interessantere Themen hast. Sehr angenehm ist Deine Art, die komplizierten Dinge auch für den Laien verständlich aufzudröseln. Der heilige Abend ist nun zwar schon rum, aber eine besinnliche Zeit wünsche ich Dir dennoch. LG André

[@l3p3]

Auch ich habe viel durch diesen Kanal gelernt und empfehle, ihn dafür auch entsprechend zu entlohnen. Dazu ist Patreon geeignet.

[@HomeDistiller]

the bonus with a separate PSU and eire feeder like this is you have a great high current low voltage DC PSU.. my dad built his own mig welder from scratch (yes that right from scratch and its about the same power as this machine!!) and we have used the PSU to directly start cars when the battery was flat!!

[@steffen1182]

Good old welding tool. Nice that someone appreciates. These tools can be repaired again and again and can withstand an EMP.

[@poptartmcjelly7054]

Three phase is great, my grandpa used to be obsessed with three phase stuff. Almost every tool in our garage has a three phase motor in it. The bench grinder is three phase and when you press the on switch it speeds up instantly and is impossible to stall out. Ps: sweet welder, my three phase arc welder can only do 180A@100% but i got it for 80 euros so i'm not complaining :D

[@shammient]

Great video, really enjoyed it. Three phase welders are very common finds at scrap yards here in Aus. I don't have three phase but still had to pick one up. A Kemppi 400amp synergic pulse mig.

[@loloaqici82qb4ipp]

It would be interesting to know what this welding machine has made over the years. Do you have any idea what it's use would have been, in which industry?

[@xysix2548]

Love your work, and the thorough explanations fill in all the gaps with details that I got rusty on over the years.

[@markbell9742]

Best explanation of 3-Φ, cleared up some fogginess I had on the subject. Cheers, Mark

[@northshorepx]

I now think I understand transformers. It's late on xmas day here in NZ and I got education as present from Germany. Thank you and Merry Xmas to you too :-)

[@hackmakestuff]

Your explanation is so didactic! I am fixing an old ESAB LKA150 that was in the trash thanks to your inspiration.

[@CajunGreenMan]

14:00 explanation of phases and volts is AWESOME! I now have a much better understanding of the phases, which is not really saying much because I'm an electro-idiot. :) Working hard to increase my understanding of electrical systems and circuits, especially DC because I own a motorcycle, and do my own work on it. Keep up the great teaching!

[@HolgerBarske]

That‘s some big project. Congrats on mastering something like that. Switching on this beast for the first time can‘t have been easy 😬.

[@willynebula6193]

I really like the idea of using a G clamp for the negative

[@HeyBirt]

A TIG/STICK welding power supply is a constant current supply. A MIG/MAG welding power supply is a constant voltage power supply. The TIG/Sick supplies have a higher open circuit voltage a relatively large voltage droop (voltage drop when welding). The output choke (coil) helps control the droop. You can wire weld with a CC type power supply if you use a voltage sensing wire feeder. With this type of feed control as the output voltage drops the wire speed does too. With a CV power supply the feeder would be a constant feed type control.

[@joe-yl6io]

I love your videos! We need more troubleshooters like you.

[@silasmarner7586]

Nice work. A monster episode! It was very well presented. One note to add for the common core transformer: Since each winding shares the common core. when one phase is active or conducting, the magnetic field in the core induces current in the "non-active" phases. This results in smaller overall ripple amplitude but at a higher frequency. This is important in EMI, but I'm not sure if it matters in this case. And it's "Ah Loooooh Miiihhh Nuhm" (4 syllables). The extra I after the "N" does not exist and should not be pronounced, even though every English person does that!

[@Subgunman]

Priced a Lincoln Mig welder for use in the EU, they wanted almost $3800 for he machine, three phase of course. A bit out of my budget. Not the massive machine you have but a decent size. Settled for a small inverter for use here in the EU.

i learn something new every time i watch one of your vids. all of my life i have tried to learn at least one new thing every day, and you are most assuredly helping me with that. vielen dank!

[@BloodAsp]

That was an absolutely amazing video! I loved learning from this style.

[@operationmickeymouseharold6780]

Merry Christmas 🎄🎁 can't wait to see u finish the rebuild upgrading to modern solid state components .

[@wolvenar]

Merry Christmas. I'm looking forward to your upgrade to switching mode. I have actually been pondering the same update to a similar welder of my own.

[@aoeuidhtnsnthdiueoa]

Super cool! Your explanations are amazing. Only thing I'm curious about, though. You're using the same power supply for both MIG and stick welding... MIG requires constant voltage and stick requires constant current for any degree of success. The transformer setup appears to be for CV, just wondering if you could elaborate a bit more on that

[@leonardpearlman4017]

I was wondering about this! It seems like the current would be varying wildly... But if it's just for an amazing test, to burn up a lot of current.... Maybe that will be discussed later. Maybe that was ALREADY discussed, a lot of information went by here, will probably watch this several times, and show it to some students as well!

[@DougHanchard]

Superb illustration of how electricity 'flows' and controlled. Well done. Merry Christmas and Happy Holidays!

[@georgelewisray]

CC vs CV /&/ THANKS-GREAT ::: Could you speak to the issue of constant current versus constant voltage welding power supplies. When you mentioned several times the possible use of the "Mig-Mag' unit for STICK WELDING alarm bells went off in my head. I reviewed your previous welding video and very much enjoyed reviewing the magnetic_shunt / stray_field transformer but the CC/CA topic was not addressed then had a quick look at the power supply videos and did not see the topic addressed there. /&/ This is WONDERFUL stuff and so well done. thanks !!!!

[@waiakalulu3501]

One of the greatest welding breakdown videos I ever saw. Thanks for making it understandable. Your talent is the ability to explain clearly and in a very logical order. I'm taking apart a welder right now, and hoping to get back welding again, so this is an inspiration to me. I must say those German units are very much to be admired for their solid construction. Wishing you peace and grace and a new year full of prosperity and good cheer. Aloha!

[@waiakalulu3501]

I often wondered if a toroidal transformer would ever have a place in making a good welder. Perhaps cooling could be accomplished by circulating oil, air or water through its center? Never seen one used this way however. As far as 3-phase, it's pretty sad we missed the boat on that while the rest of the world enjoys those benefits. Compared to mine this appears to be the stradivarius of welders so to speak.

[@DiHandley]

I want you in my bunker when the apocalypse happens, that’s for sure!

[@Pfirtzer]

You always want a German in your bunker and on your side when in need or war, they are resourcefull and veery capable technically, feeling wise German women are as warm as the Iceberg Titanic crashed into :D

[@chrisleech1565]

Now I am subbed once again. Excellent upload. There was other welder work that was wanting before you left the old digs and never completed. I was always looking for the finishing off on those projects buddy. But now we are back in the saddle!

[@caemaridwn]

Merry Christmas from "Wales". Great video explained so well, looking forward to the rest of it.

[@TheFurriestOne]

Merry Christmas and a happy new year! Nicely updated old workhorse, ready to weld all day!

[@leonardpearlman4017]

This is a great topic, I'm so IMPRESSED by that wire feeder and the general construction... but can't stop thinking: "You have three-phase power IN YOUR HOUSE?"! Suddenly I feel like a peasant. Here in the US, this is only in commercial situations, and not always then! 440Volts will really knock you down.... We all agree, if you want a bunch of DC, three-phase is the way! You're covering a lot of ground here. I have most of the STUFF we see in your videos, but nothing like the expertise and overview. I am surprised to hear that you want to stick (MMA) weld with a Constant-Voltage supply, but I haven't finished the video yet. This is very dense, and I'm watching some parts several times, or pausing to look at the drawings. It's like KZbin Polytechnic!

[@zoidberg444]

Absolutely astounding content TPAI. Can't wait for more parts.

[@rakselectric7390]

You are lucky that most or all of the homes in Germany are supplied with three phase. In New Zealand where I live single phase 230 volts is standard it's vary rare to get three phase unless when your house was being built you asked for it but it's not cheap. But my grandparents place is supplied with it because when it was being built we asked for it but it certainly helps when you have high loads. Also I think is a great idea because you can distribute lights power and heating evenley.

[@An4rcho8]

What a nice found! Love these indestructible old machines!

[@bulwinkle]

Seasons greeting to you TPAI. When you have finished this series would you give some thought to talking about the relative of these devices, the plasma cutter, and their design? I'm sure that many of us would be interested.

[@georgedennison3338]

That 'heat sink' rectifier reminds me of a selenium rectifier. I ran into one a few years ago repairing an old shop size battery charger, and learned about them. The plates are coated with selenium and were used before diodes were available/used. When they get old, the selenium coating wears off the metal plating. When that happens, a funny thing happens. When you put electricity to the worn selenium rectifier, and there is an arc at the worn spot, make sure you have fresh air, or are outside. It is a HORRID rotten egg smell, quite similar to already eaten eggs, if you get my drift! LOL MY thought was, oh, it's probably not that bad, and it's 30°, outside right now, so I'll work on it, inside. Bad move. very bad move. Glad my wife was out of town, or I would have been sleeping alone, because she would have been at a hotel... LOL I was able to remove the stinky selenium recifier and replace it with a modern, full bridge rectifier, and had great battery charger. I also added a resettable circuit breaker for overload protection. Most battery chargers have circuit breakers, but they typically die.

[@grapsorz]

Here in Norway we mostly have 230V 3phase DELTA system. no neutral and a local ground rail.

[@georgedennison3338]

You might find the Haas Kamp Three Phase to Single Phase Conversion method for welders interesting. An internet search will turn up lots of info about the method. i know Dave Kamp, one of the creators of this process, and he is a very friendly, and helpful guy. He and his partner, Haas, developed this method for the same reason you bought the MIG/MAG welder you did; the industrial duty cycle. They are freely sharing the method, hoping to get future welders into 'real' welders, instead of what is sold at home improvement stores. An internet search will turn up loads of information about the process. Dave posted the conversion on Practical Machinist, originally, and that is the best way to reach him, through that site. They have done lots of testing, and have shown the converted welders weld as well with converted single phase as they do with three phase. When I first talked to Dave about the conversion, 3-4 years ago, the cost for converting a welder was about $150, for new components. The majority of the cost is the large capacitors necessary. A very simplistic explanation of the process is a capacitor is used to store the 'third phase', then, the stored current is released at the appropriate time to create the 'third phase'. The key, for me, to understanding how this could work, was to understand that 240v single phase is not an accurate term. Conceptually, it is two phase; two legs of 120v, 180° out of phase from each other. By storing, and delaying the release of a created third leg, you end up with three legs of 120v, 120° out of phase from each other, which is, three phase. When Dave first explained it, he told me several times, what makes this possible is a welder is different than a motor, in that there is no rotation. Rotation makes timing of the three phases more critical; welders are more forgiving. Since I learned about the method for conversion, I have since learned of a device sold as a Phase Matic. I bought one from a machinist a year ago. It is simply several relays and a capacitor. Conceptually, it does the same thing, creates a third phase. The relays are responsible for the control of the third phase. You use the Phase Matic to start a three phase motor, then once it is running, it will continue to run on 'single' phase, and also generate three phase. This allows you to start additional three phase motors, as long as no single motor is larger than the first motor started. Once you get other, smaller motors started, the original motor can be shutdown, and the smaller motors will continue to run. Quite clever.

[@absurdengineering]

All it would take is to connect the same capacitors to the rectifier output. Simpler to understand, maybe, since it’s a circuit that’s common as dirt. The function of the capacitor is the same, but at the output of the rectifier. What you have with a DC three-phase welder is an AC-AC step-down transformer followed by a rectifier. Normally in constant voltage DC supplies you’d have a smoothing capacitor at the output of the rectifier. The welders don’t have it, since the 3-phase supply provides enough overlap at the rectifier output that the voltage never drops to 0V. With typical US and Canadian split-phase supplies, the phases are 180 degrees apart and both phases go to 0V at the same time. So all you need is a smoothing capacitor at the output of the rectifier, and it’ll be as good as with a 3-phase supply or even better. A certain minimum amount of capacitance is necessary since below it, the capacitors you have will carry way too high of a ripple current and will overheat. So the ripple current rating is the primary driver of cost here: once you got enough capacitors in parallel to handle the several hundreds amps of ripple current, you also got enough capacitance to keep the DC voltage quite steady - probably smoother than the output of a 3-phase rectifier. With some care put into overvoltage shunting, 50V electrolytic capacitors could be used when the rated no-load output is 30V or so.

[@guineafowl8029]

Beautifully explained. Also, a good clip on why a modern welding machine is so crap compared to the old stuff. One thing: You can just call it a MIG welder - we know what you mean!

[@dzee9481]

I love the fact that most of Europe have 3 phase power. Very very smart of the utility company to implement. 3 phase power delivery is more efficient because using a 3 phase motor is far more efficient than a single phase using a running capacitor. Too bad US did not take that on for the residential. To have that done some utility company charge you an arm and a leg to implement and setup for use in residential.

[@dragade101]

Had to look up a new MIG welder. Not sure how this one performs at peak but trying to buy this new, it probably costs north of 4kusd. A 7kusd machine gets you 300A at 60% duty cycle. Peaks at 400A, 30% duty cycle and can maintain ~240A. Meaning this is an amazing buy if you can reliably make a set of 'one time' repairs. (Netting another 10 to 25 years for only a few hundred as an investment)

[@scroungasworkshop4663]

Thanks for making me seem so intelligent to my wife as I showed her the video and she just wandered off muttering about not understanding anything you were talking about. What she didn’t know is that I didn’t either, in fact my brain had turned into scrambled eggs. Typical German over engineering, 3 phase to every house and let’s build a welder the best way possible so it can do what ever users need it to do. So many other places have an attitude like let’s build a welder as cheap as possible, put ridiculous claims on it and hope that will do. Where I live in Australia we are 230-240 volt with 3 phase to the pole but it costs a lot to put it into your house. Have you ever thought of working for NASA? Cheers Stuart 🇦🇺

[@stoatrepublic]

Amazing difference between modern hobby welder and Retro Industrial welder, while hobby might well have alloy coiled transformer and very low duty cycle, those industrial units are pure copper coiled and you can literally run that at full chat all day long on heavy steel plate and you'd burn the welding tip out and over heat the shroud long before the transformer even gets warm at the end of a long day. The only problem I have found with industrial MIG welders is the amount of dust that gets sucked into the base unit that needs to get blown out regularly with air line at least every few months at least.

[@octavmandru9219]

We had to pay arr. 500 Euros for getting the 3 phase 440V power for our apartament and basement workshop . Then an additional 300E for the thick insulated cables to our distribution panel inside the house. Not cheap, but very convenient, considering the requirements of 3 AC's, oven, induction stove and so on. Added benefit : I have 440V3ph in my workshop. Funny thing, my wife insisted we are getting this after I explained that the maximum 4.5KW supply for an apartament (acc to the national code) is insufficient even for the stove

Would love to get more into understanding and doing electronics, but turning 50 next years is old

[@kamikazeratte]

25:00 Every secondary transformer winding leads to its own full bridge rectifier (3x2 terminals), later connected at the DC side, I guess. Grüße aus dem südlichen Zipfel Niedersachsens!

Sehr schönes Projekt! Ein guter Rutsch ins neue Jahr sei dir gewünscht.

[@mdftrasher]

So glad i went for a used industrial 3 phase mig welder. However, there was a little gamble, my shed does not have a neutral. So if the machine needed a neutral for example motor steering....... Thank you for this informative video, merry mig mag ;-)

[@mdftrasher]

My shed is build about 150 meters away from a normal power source. I have made a tap from a nearby waterpump, this pump only needed l1, l2,l3 and ground/pe there was no neutral in the cable. Single phase is done with a transformer, 400 volts to 230 volts.

[@mdftrasher]

The transformer is 2000 Va, enough for my needs. I installed the transformer in 2003, works very well. Well euhhh, you get used too the hum ;-)

[@titanicjb]

What magnificent machine and your explanation is very good. Thank you.

[@BarrettFlowers]

Merry Christmas and hope yours went very well! A 14 hour upload beats anything thing that I have ever done by far. I remember when I was doing very well to make a download of 1Mb/10minutes. (9600 baud ) That was the big leap from 2,400 and pre-internet access. My next project is building a machine that does several independent things, but all driven from one DC treadmill motor. It has to be small, compact and easily carried around and somewhat rugged. Have you checked your e-mail lately? :) Have a great New Years from UTAH, USA!

Three phase is common in rural properties and commercial properties in the U.K. In most urban properties the phases are split between houses.

[@atman5230]

It's good that you invested your money in the old powerfull welder rather than the new wimp Chinese welder.You have removed the capacitor so you don't have to worry about a surge of electricity while doing a low amp weld which would mess up the weld and maybe make a hole in the metal if it were thin metal that you would be welding..so now you will have better control welding without the capacitor. Can you do a video on anti-gravity soon ?

[@Sawsquatch]

Misread the title as migmaw welder, and now I have two natives stuck together in my garage.

[@audiocrush]

19:30 I actually did that with an 80V 100.000µF cap (huge thing) and a big bridge rectifier on my old welding transformer, that was a hell of a bang, the tip of my 3.2mm electrode was just gone xD Actually it was quite a lot of fun so I did it a couple of times more until the whole electrode was gone :D

I have a old stick welder. and a cheap might welder. I was thinking about combining the two. or just use the stick as power and the might as a wire feeder. and gas supply. maybe get a longer and better trigger and supply line. the stick welder is a old unit. I think may have been used in a factory. it is a 100% full power/ duty .

Sometimes you can find one for cheap on eBay and they deliver to your door. Love your detailed explanations and understanding of electricity too.

Excellent video, not least because I understood every single word of the theory. Merry Christmas & happy new year to you and your family. Regards Mark in the UK p.s. I think you probably DO already know this, but seldom is there 3 phase supplied to a residential property, unless perhaps a (previously commercial/industrial) building which has been converted at some time, then 3 phase may be available. I can't say for absolute for certain, but I believe all new builds would be single phase. You may also be aware that we have what I believe is referred to as 'bonded Earth' in the UK. I also believe that this is to reduce/prevent the possibility of 'difference in electrical potential' between say, an electric cooker and a sink. How is this issue dealt with, with 3 phases being available in a domestic environment in Germany? Of course I'm referring to the 400V between phases.
