Hi guys, in this video let's see how to modify a vintage rescuer that was given to me by a dear fan (Edoardo) here in the Turin province
In fact, in this project we see together how to take an electrode welder with a classic basic transformer and convert it into a high voltage Tig savior
For the uninitiated, the advantages of welding with Thing are really interesting, because it allows us to weld really thin metals and with extreme precision, in fact it is exactly like welding with a blowtorch by adding but by hand with a filler rod of the additional metal which will create a have own welding
In this case the initial value of the rescuer was less than €30 as it was all damaged and dated
By making this simple modification we definitely increase the value of the savior itself and also its functionality in this case we are welding a Thing in alternating current
It is obvious that an inert gas must also be added through its original tube, in this case it is pure argon
 I still have to get carried away with this technique but it seems really easy to learn you just need to practice hours and hours
to achieve perfection
In this video I took a flashback of an old CRT TV and I connected a special driver that shoots a high frequency and manages to increase the fly back output voltage
We will need this voltage to charge the capacitors in this case I advise you to buy 50 kg volt capacitors or alternatively try to build one using the table that I have superimposed
Playing with high voltage can be dangerous if not fatal for some individuals so I advise you to avoid playing with these things and promptly close them inside an airtight box so as to avoid any risk of getting an electric shock
I would like to reiterate not to touch the high voltage electrodes of the flyback in any way, let alone the capacitors that remain charged, as I risked really hurting myself or possibly ending up in the morgue.
Having said that, which must be said by law, let's continue with the description of the project
In this way with this modification we are able to have a Thing torch connected directly to the savior to the mass and on the other end instead we place a self-built transformer
By doing so we will obtain a savior capable of generating 40 V and 160 A maximum as originally
But at the same time 4000 or 5000 V will come out of the same Tg torch with one for today instead negligible
By combining your things together we will obtain a spark long enough to propagate on any metal conductor thus avoiding having to do a sketch start
So the tiger electrode of the torch will never touch the metal surface managing to weld even with an initial distance of about two or 3 mm
More than enough to avoid contact which would tend to ruin the tungsten electric car
Ruining I have it. Or by making molten metal build up on tungsten
So I would say that I am very satisfied with this result with this small high voltage transformer I will be able to weld a Thing without having to scrub stand all the time
I hope you can take inspiration you changed understood something new
Especially with regard to the induction coil, in fact this is precisely the principle of this transformer which is able to wirelessly transmit electric current from one coil to another

[@Equiluxe1]

Years ago I had an old ESAB HF unit for tig welding. I took it apart to look inside and found that it was a Bosch ignition coil driven from a transformer with a spark plug and a capacitor, this produced the HF for tig ignition, just using the hf with the welding transformer turned of in the dark you could draw the spark out to nearly a meter and still see it. Got rid of it in the end as the HF would travel back up into the mains circuit and fry any electronics on the same meter, did two workshop fax machines in before I traded it in for a new tig machine which was less that half the power as the transformer unit was rated at 450 amps continuous at 95 volts.

[@TheDivergentDrummer]

For those of you talking about reversing the polarity, The polarity reverses at how ever many Hz the mains is at ( at lest where it enters the circuit. The frequency must be being driven up by the driver board to get the high frequency switching needed to generate that current. Being as he is using electromagnetic coils such as the fly-back and the home made transformer, the circuit is 100% AC, not DC. The alternating current passing through the blue coil is inducing an voltage in the black coil as it is the secondary in this transformer. The only place where DC may be found here is across his capacitor across the flyback transformer. It's important to note, that: 1. Transformers can NOT pass a DC. If he were to rectify the output of the secondary, then it would be DC. 2. Capacitors, such as the one he has here, or any for that matter, can NOT pass DC current. They only pass Alternating current. DC has no frequency ( as it's polarity never changes ). The Equation for this ( not for the math, but so if you are reading this, a little context to why) . Xc = 1 / 2πfC where : Xc = Capacitive Reactance. a "resistance" measurement of the capacitor. π = a tasty snack ( blueberry maybe? :)) f = Frequency C = capacitance The fact that f and C are both on the lower half of the equation on the right side, ( as in 1 / fc), indicates the the Capacitive reactance is INVERSELY PROPORTIONAL to the frequency and the capacitance, that means that as frequency lowers, the Capacitive Reactance (Xc) goes up. So at a Frequency of 0 (Direct current) the Xc would be infinite. infinite resistance means nothing gets through. Conversely, if we put an AC signal through the capacitor, AC current is allowed to flow, as it's frequency is not zero, so it's Xc would not be infinite. Also to note, a lot of the current generated in this setup comes from back EMF spikes (aka CEMF, Counter EMF, technical term is actually Counter EelectroMotive Force ) when the coil is turned off. Hence the higher the frequency, the more power. In a typical transformer circuit, you would have a flyback diode or freewheeling diode, reverse biased across the output to handle those spikes (shunting them to ground) in this scenario, we actively use them. They can be in the order of hundreds to thousands of volts. Now I have a HUGE pile of old drives here. I wonder how big of a capacitor I can make LOL! I've never seen that before with the platters. Physics never cease to amaze me.

[@jacobyunderhill3999]

A transformer can only pass AC, but an inductor can pass both. You clearly have a solid understanding of theory but have misunderstood what's actually happening here. The current from the welder can ABSOLUTELY be DC, and only passes through one side of the diy transformer, effectively an inductor in that circuit. That DC can coexist perfectly happily with a HF AC signal induced from the flyback. This concept is used in nearly all vacuum tube circuits, for example, guitar amplifiers. You send +300 VDC through one side of an output transformer to charge the plate (anode) of the tube, the signal from the grid imparts an AC modulation on the DC which is coupled via the transformer of which the other side is connected directly to a speaker. The speaker never sees the DC and happily transduces the AC modulation as sound. The topology is very similar here, the signal path is just reversed. The isolated flyback circuit takes the place of the speaker, and instead of the AC-modulated-DC going to a tube plate, it's the TIG tip.

[@jasonbarnes8047]

They're talking about reversing the electrodes that the handle and clamp are plugged into. As in the work piece needs to be swapped in polarity with the tig torch. Its needed to switch for certain welding methods or wire types

[@TheDivergentDrummer]

@@jasonbarnes8047 yup. Am aware. You are referring to DCEN vs DCEP. Difference being one gives more penetration and the other more cleaning of the weld. Doesn’t change the fact that a transformer can not pass DC, and work on AC only. The Electrode and ground side are connected directly to the output of the secondary. If you take a multi meter across this leads measuring voltage, you’ll see, it’s ac voltage. A transformer, works on AC ONLY and CAN NOT PASS DC. There is NO rectifier after the winding the torch is connected to.

[@jasonbarnes8047]

@@TheDivergentDrummer then you really wanna look into how dc flybacks work cause you're actually wrong they do work with DC, they have to be pulsed or zero volts switching ie zvs drivers.

[@TheDivergentDrummer]

@@jasonbarnes8047 then please show me where the secondary, that is directly attached to the hot and neutral sides of the transformer ( not the fly back, the home built job it’s as that is the last coil in the circuit) is rectified into DC. Alternatively, I am open to your explanation of HOW the AC coming out of the transformer is DC. There is no diode to even half rectify the waveform on the output. "Does Tesla coil produce AC or DC? AC In coils that produce air discharges, such as those built for entertainment, electrical energy from the secondary and toroid is transferred to the surrounding air as electrical charge, heat, light, and sound. The process is similar to charging or discharging a capacitor, except that a Tesla coil uses AC instead of DC." The fact is, a transformer can NOT produce a DC voltage. It is AC that needs to be rectified. With a frequency of 0, there will be NO magnetic flux field change and therefor no current present. HOWEVER, pulsed DC can be used in a coupled induction scenario as he has here. That is, only if the driver is pulsing the DC on and off to generate the change in mag flux. As mentioned before, the back EMF caused in the secondary can be in the order of the hundreds to thousands of volts, and a regulated transformer will heat up , reducing it's efficiencies. The only way to 'reverse' the polarity, is to redesign the flyback driver so that it is pulsing the negative half cycle, not the positive.

[@mediumsmoke7823]

This is really cool! I did think of something similar for my own welder. When Tig welding the handpiece must be the negative pole. Otherwise the tungsten burns up very fast. And with every other welding method it has to be positive. Thats because the positive side always gets hotter than the negative. When you are tig welding you dont want your tungsten to get too hot. With every other method you want to melt of wire or an electrode so you even want it to get very hot.

you still need shielding gas like ARGON which would give you a much more stable arc. Everytime I use C02/argon mix the TIG goes nuts. Where as if you use 100% argon on a mig it will literally throw the weld.

[@pablobasan8664]

excelente video. lo voy a intentar

[@cdrom1070]

and for the coil if you want to use the first method with the copper tube, you need to get a LCR meter, or measure LCR with a function generator and scope (at lower frequencies its cheap to make a LCR circuit with any old function generator) so you can get the inductance and the coupling right. A real coil from a welder has a bus bar wrapped like you did (similar size), but inside they have a ferrite rod that is wrapped in wire, then put in a teflon sleeve, then thats put in the coil. They do not wrap the wire in between the primary coil like you did. I think this leads to much higher *unwanted* capaictive coupling (its like a common mode vs differential mode thing). The ferrite rod I am not sure about the material. I hate rod inductors and I don't blame you at all for giving up on that, I don't know how critical the material is, but you got the size right. If you try again, try with a iron (rusty) nail, wrap it in wire loosely spaced like the coil, put a sleeve on it, then slide that into the tube. For high frequency I think you want a common zinc material (found in power supplies and such) 70 series or something.

Lots of work... There was no way the stainless steel core would work. Most of the time stainless is non-magnetic so a very poor choice for a magnetic core. The version with the transformer is not that much better given that the transformer core is intended for low-frequency currents. You either need no core at all (i.e. just air) like in Tesla coils, or a HF core made of ferrite. But your enthusiasm is contagious !

[@hhkk6155]

Ideal? Absolutely no. Will work? Absolutely yes

[@alexwang007]

You want a core material with good permiability (higher than air) to guide the flux from one winding to the other. An air core also works, just makes your inductance really low meaning it would prefer a much higher frequency without having huge current consumption. (Hence why Tesla coils are usually loosely coupled transformers with 100s of kilohertz of resonant frequency). The impedance of an inductor is j*2*pi*f*L ohms, so a lower inductance would draw a lot more current at a given frequency than a higher inductance. This gets more complicated when you want to match the transformer's impedance to the discharge circuit to ensure maximum power transfer. So stainless steel isn't ideal.

14:11 you can easily make a foot pedal from (preferably) a non-conductive material like wood, a few screws, and one or two compression springs. Oh and the same pressure switch. Just make a housing that holds that switch with holes for wiring and two screws to function as pins. Make a pedal that slides easily in and out of the housing. The. Attach one end to the housing with some screws or bolts and loose enough to allow rotation on that axis. Put one or two compression springs slightly closer to keep the pedal slightly adjar. Mechanically attach the pressure switch inside and if necessary add a nipple to engage the switch if your sorings require too much compression before closing the switch. Make sure the springs are powerful enough to open the switch and functions as a Deadman switch.

TIG = Tungsten Inert Gas welding process where an inert gas, typically Argon is used to shield the molten metal from Oxygen. You didn't have a gas cylinder or a hose connection to the gas inlet of the TIG torch. That may be why your results didn't look very good. Also the welding machine you are using is an AC machine. Typically AC is only used with TIG for aluminum. You need DC for steel and other ferrous metals. Overall, your "contactless start" HF adapter is pretty clever and demonstrates the inner workings of many TIG welding power supplies.

Love your project! It is very creative. I've never seen a TIG arc throw sparks like that. I'm curious if you actually used any shield gas. Pure argon would be best for what you are doing. About 15 cubic feet per hour for that small cup on your torch. More for a bigger cup; you want to maintain laminar flow. If it gets turbulent oxygen from the air mixes with your shield gas. Sorry I don't know the metric conversion but a guy like you won't have any trouble. Best wishes from USA!

All of the popping was the absence of shielding gas.

[@lloydscharf6897]

Guess I missed the need to use shelding gas. There is a comersial device that adds high frequency called a "TIG-PIG" granted it's more $$ but it will do AC which is prefered,if not needed for Aluminum (yes you can weld Al on DC but will eat up your Tungstan and not give good cleaning). With out hi frequency I've never been able to hold a TIG arc. AC Stick electrodes have something in the flux coating that maintains the arc.

I like the capacitor alot, just be sure to clean it very well before assembly *ultrasonic recommended) and deburr the edges o the sheets so they come together real nice, you don't want a bur preventing it from sitting beautifully. I also recommend brazing a copper sheet piece to the disks so you can solder it to a wire (I recommend a teflon wire or better yet a bus wire with a extra thick teflon tube put over it, it will be like a real component). You don't want arcing on the interface between the capacitor plate and the wire that leads to corrosive gas build up (nitrogen dioxide etc) that leads to a contamination failure.

[@kde5fan737]

Is there any reason to use those old platters vs a thin piece of aluminum (if it is cut & prepped correctly)? I could get different thicknesses of Al if this matters & have it laser cut to shape (as well as the insulator - I have acrylic, polycarbonate, LDPE, HDPE, UHMEPE & PP). I'd like to build a nice HV cap and ideally make it as light as possible. So I'm just curious as to the reasoning for the plate selection (hard drive disc vs other material). also, wouldn't something other than the HD platter allow for more capacity/storage due to the differences in finish? With the super polish (sputter coated?) platter I would think there are not a lot of microscopic imperfections (peaks, valleys, etc) which would be present on rolled sheet aluminum - which I would think would give more surface area. I wonder if surfaces could be prepped to give a lot more surface area by using an acid or base to dissolve a little of it away.?

[@cdrom1070]

@@kde5fan737 idk, the impedance is lower though with a smooth surface. But the wire is like a giant choke to that difference. Very high frequency microwave stuff is mirror polished to keep impedance lower and more stable. IDK about the capacitance, it would be interesting to see if you can pick up that difference But high frequency microwave PCB have surface roughness specs that are hard to meet. I bet the hard drive makes a more stable capacitor. Does it really matter for a welding machine though... idk probobly not. Maybe if its robotic and very precise. To test it though would be hard, you would need a pin fit capacitor that has identical plates of both materials (replicate hard drive plate with bad surface) and compare both of them on a precision LCR meter. I think the differnece would be so low that you would need a very stable mechanical setup to pick it up reliably.

If you have a smooth flow of argon already it may be possible you need to reverse the polarity. I am not an expert, but I know if the DC power flows the wrong way it will throw sparks like this. If that is ok maybe the argon is flowing too fast, blowing the puddle away. Could use a bigger ceramic cup as well.

this is not a rectified but AC current, possibly good for Aluminium welding but, the duty cycle is fixed to 50% and frequency fixed to whatever you have in your mains supply (50Hz or 60Hz). The tungsten will ball like it does in Aluminium welding so use the same electrodes used for Al welding. You will not get much penetration but should be enough for non-critical hobby welding. It could also be used for stick welding cold starting.

Does this work with switching PSU IGBT MIG machines?

[@deepwinter77]

Cool video, you really need a DC welder/power source, The Unit you have is an AC unit that's what's causing your torch to look like a flame thrower, You can get DC welders very cheap just swap your power cables and you will be amazed at the difference. This type of AC isn't practical for welding aluminium either because of the balance between position and negative and frequency. You could add a bridge rectifier though to convert the AC to DC Another thing you could do is add a gas solenoid that would be a cool upgrade.

I dint think he is using any shielding gas, as others have pointed out. And he is using DC.

[@deepwinter77]

​​@@oddjobbob8742The Machine he is using is an AC machine. At around 14.40 he shows the gas connection coming off the Dinse power connector and mentions it I believe. You can't really Tig properly without gas given that and what he shows in the video I would assume he's using gas that goes straight to the torch and doesn't go through the machine. Maybe he didn't hook it up or turn the torch valve on.

[@oddjobbob8742]

@@deepwinter77 I do agree with you about the gas connection. Even the handle he is using looks like the same handle in my TIG welder. I think yiu can weld with a TIG welder, though badly, if you are using rod that has some sort of shielding flus in/on the rod. I have looked closely to all the shots of the welding machine and I don’t see anywhere that might indicate it is an AC output machine. Please clue me in. I own a multi function TIG/STICK/Plasma machine. It is DC output only. Which means I can’t weld aluminum because it won’t “descale” the aluminum oxide off the aluminum surface. I am always in search of a gadget that will convert the output from DC to AC. This KZbin looks like it might do that. But if the output is already AC then this is just a converter not an inverter. Cheers. Thank you for the reply.

[@luizmattos9031]

Do you try a change the rod for ferretir with espiral. Do you use high frequency. Ferrite is better.

[@danielkarrenbauer6843]

Bene, but why does the spark eventually ceases to be stable in the glass container after you started the welding process? Is this just initiating the "first" spark?

[@cyrusthegreatcyrusthegreat4396]

Does it weld ac aluminum?

[@Meno-Sebastiano-Argenti]

HI mate!!! please could you make a welding device similar to Multiplaz 3500? Thank you.

[@engjds]

Weird build, least there is nothing immediately dangerous on this one like the plasma video, there are questions like does it supply enough current to initiate the spark? did you even research the current required? will it just extinguish soon as the Argon is applied?

[@mustafae75]

Did you use any gas?

[@francoisbelangerboisclair]

You could have replaced the two nails by a car spark plug. Stainless, titanium or aluminium make really bad core. You need a ferrous metal. If a magnet stick to it hard. You are good to go. And yes, your spark system could create serious issue. You are generating a lot of "jamming" and electromagnetic pulse. In some way, you build a transmitter. That can be a legal issue. With a few modification. I can transform your project into an EMP device. Meaning it can probably fry some electronic...

You can wear more flexible gloves for TIG. They are usually white. You should wear them and check flexibility.
