My DIY welding inverter (made of scrap)

Ғылым және технология

Today let's take a look at my homemade inverter welder. It's a bit unfinished and dodgy, but it works well :). Just like my questionable DIY welding mask.

    Man oh man! Nothing better than a temporary solution that turns permanent. 😁👍 I wish I could find a way to easily ship things to you from the usa. There have been dozens of times over the past few years where I wanted to ship you something after one of your videos. A buddy of mine runs a local industrial scrap yard and he gets welders and stuff by the truck load. You wouldn't believe the government entities and big companies who just scrap everything after one big job is finished because it's cheaper to write it off on their taxes. Literally stuff that is less than a year old. It makes more financial sense for them to crush it all at the scrapyard then to try and sell it or whatever. They Don't really allow the public to come in and buy stuff but I go by there a few days a week and he lets me have whatever for about $0.08 per pound no matter what it is. I used to be thousands of pounds of stuff every month sometimes thousands of pounds per week. And it went on like that for the first 2 or 3 years. But it's been 6-7 years now... And you just can't do that constantly you just can't keep up with that pace. It's more than a full-time job and then you end up realizing you don't get to work on projects because it's a full-time job keeping up with all of that stuff He doesn't keep anything anymore he just crushes at all unless I want it. a lot of the government stuff it comes in has to be crushed because it's a mandatory things since it was bought with taxpayer money. But I still get whatever I want and a lot of times donate it to schools and stuff like that when I find someone looking for something, or really need it, or I have the time. But it's a full-time job and I just don't have the time. You can only use so many things. And you can only have so many storage buildings. Then....If you can't find something when you need it or easily get to it.....then you might as well not have it at all.

It's still very impressive, even ten years later :-D Hope you fixed the exhaust, exhausting work :) The sub 17v supply looks like it has a "Top" chip or similar, it's amazing how minimal the circuit can become :-). I have been to your site quite a few times, you did build a power supply that was massive, or perhaps it was a welder, my memory is bad. Some of the small supplys i have saved the diagrams, just for personal use only. The section on p.c switchmode diagrams is very handy for reference.

    You are awesome! How do you do the varnish coated wire for your transformers? I've managed to salvage some wire for rewinding once but most of the wire I've come across is not good enough for rewinding. The varnish tends to be brittle and crack after removing it. To answer everyones first question, yes, I very carefully remove the wire. I'm usually counting windings as it is and will carefully unwind and rewind at the same time or will wind it onto a fresh bobbin. The wire usually looks fine as soon as I remove it, but after letting it sit for a few days I can see small cracks showing tarnish from bare copper. Are you sourcing new copper wire, coating your own, or are there other sources of coated wire I should be looking for? -Jake

  • @DiodeGoneWild

    @DiodeGoneWild

    5 жыл бұрын

    You'd have to ba crazy to coat the wire youself ;). I use an old coated wire from old devices. Deflection coils of old CRT televisions are a good source of a wire. Also sme transformers (not in resin). Some fluorescent ballasts. Some motors (for example microwave oven fans) have a nice coated wire, the winding is not in resin. Also some electromagnets and relay coils are a good source of wire. Also water pump motors from washing machines have a nice winding that you can easily unwind. Also the degaussing coils of CRT monitors or TVs (the big rectangle around the CRT, in a sticky tape).

    There was a time when people were responsible for their own actions! Not today where the lawyers and insurance companies are slowly making most equipment unserviceable due to crazy safety requirements. Some of the old tube radios I work on have exposed mains on the back some even have a scary accessory plug with B+ 300-600 volts dc typically in a plug that has zero recess on the terminals! If you don’t know what your doing don’t do it, if you are learning ask someone that knows read, read some more and be prepared to get a shock or two that’s just how life goes when working on this stuff. But you must know the difference between something that will just make you mad and hurt vs something that one mistake will kill you instantly like the smoothing caps in a high powered transmitter or high voltage power lines.

    This one is for 220-240V 50-60Hz mains. It may draw about 10A at most from the mains. The maximum output current is 100A.

    Thanks a lot. Is there a reason why the voltage isn't adjustable? You converted this welder into a power supply with adjustable current and voltage, but you use 3845 insted of the 3844 can I use the later one as I don't have the 3845?

    You made a good job of that im impressed how much does it draw from the mains? Ive seen someone welding straight from mains no rectifier or current control yours is far superior

    that might be possible in the US, where you can have silly things like 400A service, but here in EU, where the grid is mostly 230V (or 400V between phases), you'd have problems sourcing more then 32A out of commonly available 3-phase sockets.

    I've gotta hand it to you.... perseverance to sit and wind all the coils. You're proud of them I can tell, and so you should be. I was surprised to see an iron lamination transformer in the output. At 40khz switching, that would be inefficient due to eddy current and hysteresis losses. And it's very heavy. The choke at 40khz would be a similar problem with the bh curve characteristics of iron. The output transformer then looks more like something designed for 100hz, 1khz, 10khz maybe. Please cover the capacitor bank. The charge energy in there is significant and deadly. :) gm2020 . Edited: I saw on ur site, it's not iron laminated output transformer. The two big ferrite cores are impressive. :) Good answer given as to why DC rectification is used with inverter welders - yes the inductive reactance in leads at high frequencies! All around real nice, but a bit on the dangerous side :P

    this is a great project. thanks for sharing. why did you make it with DC output instead of AC? you already had 40 KHz. does that not work with welding? what is the Dc output voltage? is it around 9V like u said?

    High frequency voltage isn't good for welding. At 40kHz and such a high current, just the inductance of the welding cables would be a big problem. And of course, most electrodes require DC.

    Did I say anything about 9V? I think that the arc voltage may be like 12-15V at a very short arc or about 30-35V at a very long arc. Mostly like 20-25V.

However i dont know how much current was passing at the time. so u say that short arc is 12-15V and average is about 25V... thanks. i often wondered about this.

    Hello my friend, can you help me a little. I said I tried a lot in making this device but it does not work well. There is something wrong with the circuit. I hope I can understand from you. Have you made any change to the basic scheme ??? Because the gate transistor heats up when it turns on the gate feed transformer..what should the voltage be on the gate transistor IRG4PF50W? Thanks

    Coolest thing ever mate ! As I have seen many inverters as yours in the internet this led me to a question. Why it seems that every inverter has a primary current regulation ? Because for accuracy and tight regulation wouldn´t it be better to measure at the secondary side of the transformer ? Yeah I know that there is DC on the far right but I mean directly at the output of the secondary where still AC exist so you can use the current transformer there too.

    Nice build! I made one of those with only a transformer. I wound 750 turns of primary and 20 turns of very thick wire as the secondary. The only downside is that the secondary melts after long usage.

    I would like to see you TRYING to weld a rusty tissue-thin exhaust pipe with any 'stick' welder. I remember the time my uncle bought a stick welder, the type that runs off a car battery. By the time he'd finished welding his old banger car, it had more holes in it than before he started!
