DIY Spot Welding Machine

[@kenw.1112]

This is a excellent video on making a spot welder . Thank You! I have repaired microwave ovens for over 30 years . A cautionary note for anyone who is going to take apart a microwave oven for parts . There are high voltages with LETHAL CURRENT present inside microwave ovens. No Exceptions be sure microwave oven is unplugged and for extra safety short the magnatron high v. capacitor out. It has a bleeder resistor but do it anyway. A guy down the street opened his broken microwave to attempt fixing it. He reached inside and was electrocuted died on the spot.

[@pikudopikao8425]

You know, in short time the capacitors just discharge by themselves but yes, it is very dangerous.

[@husse843]

[@stoneisland1000]

[@tinkmarshino]

that is good advice but what does the magnetron high voltage capacitor look like and where is it? Also how do you discharge it?

[@FragBenitez]

I just read this after dismantling a broken microwave oven, fishing for the transformer. Guess I'm lucky, but yeah I got a little cautious when I saw a big capacitor inside, thought to myself "I should have discharged that". I work with CRT monitors so I know this can be lethal.

[@tinkerbit]

Removing the transformer shunts increases the available power but introduces a risk of core saturation and overloading the primary.

[@MysticalDork]

be very careful if you use the first method because you can easily damage the enamel insulation on the primary and cause a short circuit to the core. Paint the part of the primary that was in contact with the core with some nail polish or similar, and use a sheet of card or plastic to ensure that there are no shorts.

[@tinkerbit]

OK. Thank you!

To doskonały film na temat tworzenia spawacza. Dziękuję Ci! Od ponad 30 lat naprawiam kuchenki mikrofalowe. Uwaga ostrzegawcza dla każdego, kto ma zamiar rozebrać kuchenkę mikrofalową na części. Wewnątrz kuchenek mikrofalowych obecne są wysokie napięcia z LETHAL CURRENT. Nie ma wyjątków, upewnij się, że kuchenka mikrofalowa jest odłączona, a dla dodatkowego bezpieczeństwa krótki jest kondensator o dużej pojemności. Ma rezystor upustowy, ale tak czy inaczej. Facet na dole otworzył złamaną kuchenkę mikrofalową, żeby spróbować ją naprawić. Sięgnął do środka i został porażony prądem, zmarł na miejscu.

Thanks for translating it into other languages. I barely know any polish and I know English very well but I still think everyone should hear the dangers of these “fun crafts”

[@jakenbaked87]

If you do two in series, you can make a stick welder. If you attach a RMS current regulator and high current diodes, you get even better results.

El hilo está recubierto de una laca aislante con lo que no tiene por qué haber ningún problema. Supongo que ese papel blanco es para proteger más y para que encaje bien y no se mueva. Siempre hay que actuar con sentido común. Esto está pensado y dimensionado para un microondas y no para un soldador, con lo que deberemos estar bien atentos que no se caliente. No es para un uso continuado o industrial sino más bien entre casero y experimental.

[@kilian.franke]

Question: Where does the power come from at 1:40 ? is the cable you can see below just plugged in to the wall? wouldnt that short the circuit?

[@tinkerbit]

Yes to the wall 230 volts. No short circuit, but it heats ...

[@davidq1164]

0:50 what's the reason to connect original transformer secondary coil to main is fatally dangerous? Wouldn't that making the transformer a step down and very low voltage per turn one? Not of much use as the power will be extremely low but didn't see the dangerous.

[@DevinDTV]

Stupid question: If there's no load, why's the current only 500mA or so before being transformed? Surely there isn't 400+ ohms just from the copper wire itself, right?

[@tinkerbit]

No, I haven`t. Since the distance between the tips is very short and the iron plates to weld are thin the resistance is low so I think you dont need more voltage. You needs Amps.

[@tinkerbit]

The main reason is that I am Spanish and my English pronunciation is far from perfect. Other reason is operative: in order to make a good sound a voice over is needed. Even in my own language is not easy to speek. When we see TV newsreaders we usually think that it is easy, but when you try the results are too much different. If you want you can see and hear me in Spanish in this youtube channel: cienciabit I am trying to improve my diction, intonation, diction, etc, .... but it is not easy.

[@alextrombogosy293]

I understood , im Brazilian and i have the same problem

[@GRAHAMAUS]

Have you done any tests to see how thick the metal can be and still make a good weld? I have an old microwave transformer - might give it a go myself. A nice touch would be a microswitch that turns on the primary when the jaws are closed (safely insulated of course).

[@AJRestoration]

What are the use of the shunts in the transformer?

[@tinkerbit]

Limit the current.

[@AJRestoration]

so in other words the thicker the shunts, the less amps you will have?

[@tinkerbit]

No. Only the plates that are inside. Mine is only for experimentation not for serious uses.

[@johnconrad5487]

looks like all the DIY spot welders are the same. one or two microwave transformers and some fat wire connected to some mechanical contraption to make the weld. did any ever make one that works off the mains power?

[@eugbug1]

Microwave oven transformers are great for projects because unlike some other transformers, the core is in an 'E I" format. So the 'I' limb can be removed easily. I made my new high current switch mode power supply (20A DC) using a re-wound microwave oven transformer. After cutting the core I clamped the 'I' part back on using two steel plates rather than re-welding. They're great for use as powerful electromagnets also. The primary can be run on low voltage DC with the secondary removed. A suppression diode should be used on any switching circuitry to protect semiconductors or contacts of relays.

[@milankral5891]

Také jsem zkoušel zdroje postavit, zejména nabíječky a nikdy se to neosvědčilo jako když jsem si precizně navinul svoje spočítané trafo z originál plechů. Tohle má ohromné ztráty - i naprázdno je odběr okolo 3-4 A. Dá se to sice zregulovat elektronikou, ale ty ztráty jsou tam pořád. Jediné uspokojivé použití by bylo jako booster - pro krátkodobé použití k nastartování vozidla. Ale musíte použít pořádné 100-120 A diody + chladiče.

[@hyparh]

The shunts are there for some current limitation so I don't think they need to be kept, especially in this case, when we need as high current as possible.

[@aaronwest2511]

Just a quick question, what would happen if you didn't put the metal shunts back in?

[@nazshey6594]

Hi, what's the size of the Single Core wire? How thick it should be???

[@UberAlphaSirus]

No, the primary, the mains side, has to be rated at your outlet voltage. the secondary, the output side you can do what ever you want with it, it will not effect the primary as it is set to give a set amount of power thru the core. However the secondary is your own design, so you could over do things on that side.

[@dans4270]

Can anyone explain to me hoe electricity it getting through to the connectors? The wire is isolated and not touching 🤔

[@tinkerbit]

Because the big amperage is only at the secondary circuit, this is in the thick cable. The primary is at 230 V and perhaps 10 A, so the circuit breaker doesnt flip. The secondary is "isolated" from the primary, this is called galvanic isolation. The circuit breaker "feels" what happens with the primary, but knows nothing about what happens to the secondary.

[@tinkerbit]

Well, I am not an expert, and more a tinkerer. With the plates out the trafo gives more current, and more heat. So if you quit them take more care. I have read on some place that it is possible that the trafo gets hot with the secondary open so only connect it when you "spark it". And dont touch the trafo when it is connected to the mains.

[@qaisarawan93]

nice video I tried to follow along with it and bought a used MOT, the seller connected ac voltage to the primary winding (thin wire side). And it created humming sound. At home I removed that side and when I connected ac to the secondary side it created smoke and smell and became very hot to touch. Seems like the Secondary was already short? What you say? Also Now can i rewind it using suitable size enameled wire? Will winding it with slightly thinner wire be ok for spot welding?

[@Mr.Neko013]

This most likely has been asked, but I'd like to know how strong are the welds? I've been wanting to build this, and now I need some spot welding done on my car's front end for a part that is spot welded in that needs replacing. Will this be strong enough? It's for the radiator core brace

[@jeffreydeutsch7336]

Try it on a couple of pieces of scrap of about the same thickness. Nobody can predict what your transformer and your wire and your tips are going to do. Make a test weld and try to break it

[@copo7205]

why did you leave the primary instead of the secondary? It's got way fewer loops -> less current transfered to the thick wire

[@enoc24]

hello I'm doing grant the machine you have in your video such as heco beam which does not have much power but I must be conectralo 220 v instead of connecting on 110 v the label says it must be connected to 110 v but as you remove the secondary transformer do not know if this changes or if I put thick cable is very thic

[@two_number_nines]

what would happed if i add turns to the first winding so it reaches half of the max possible windings volume, then remove the iron between primary and secondary and then fill the remaining space with 6-7 mm cable?

[@ОлегМоргун-д8р]

why cut the core with a grinder when you can cut a secondary (high-voltage winding) with a normal hacksaw and then wind 1-2 turns of a thick cable ..... I don’t know how you do, but I don’t have a welding machine yet to weld the core back.

[@jaybrine5034]

What is the red coated wire winding that is between the primary and the secondary windings used for?

[@tinkerbit]

I think is for the resistor wire of the magnetron.

[@javiergonzales8487]

What Circuit is being used to power the transformer when the spot welding is being performed ? Direct connection between the Transformer and the power strip ?

[@everafterinkable]

Where do you get the primary, secondary part your taking apart? What did it come out of?

[@Rambo650]

I have to teach myself spot welding at work, and I've never done welding before. The electrodes on my welder are attached to chords (not like this clamp down setup). I just want to know, what are all the possible ways I can hurt or kill myself? Are gloves mandatory? And since I'm putting high voltage through metals, when can I hold the metal after a weld? Stupid questions but I want a heads up before I get electrocuted.

[@marionnepatrick7383]

sir, whats the significance of putting the shunts back in the reassembly?

[@antoniocarlostiburciodecar7069]

good afternoon!!would it work for you to use the primary of the other transformer, as a secondary of the transformer you opened? in that case it would be 220v input and 220v output of the transformer, what do you think?

[@perspectivex]

I think you're describing this en.wikipedia.org/wiki/Isolation_transformer

[@beholderer]

Can you use a normal tranformer to do this and an arc welder as well, or is it a must to use a microwave transformer? thank you.

[@rastakyborg97]

I think he used a microwave transformer because the cross section of the core is big enough to give over the power.

[@beholderer]

Yeah, it makes sense, I was thinking about that as well but was not sure, thank you for your comment man, really helps :)

[@TheFirefox780]

I'm building something like this but I have a question I can't quite figure out, in your thick wire secondary coils would that be considered 1 or 2 turns around?

[@tinkerbit]

1,5 turns.

[@TheFirefox780]

Thank you

[@theophrastusbaumast5936]

mopatin Im building a spot welder.... i removed the secondary coil from the MOT...... however, i also removed the insulation between the secondary and the inside wall of the transformer. I noticed your first method didnt have insulation between the weld cable and the walls of transformer. The primary insulation is fine, the secondary is gone however. I am using 32mm welding cable as i couldnt find 35mm yets its pretty thick. I beleive 32mm translates to 2 gauge i believe. Two questions......shoukd i insulate the inner walls before winding in my welding cable with say electrical tape and possible cardboard? Second, you think 32mm welding cable is sufficient?

[@danyk666]

You just made the transformer very DANGEROUS because you forgot to put one of the primary insulation papers back. Now you easily get mains voltage in the core and possibly in the output, because the low melting point of the secondary's rubber insulation.

[@franktechniek]

***** Exactly what I thought. I also don't understand why removing the primary and immediately reinstalling it again. Just leave it in place...

[@nebnoswel]

***** The primary windings are all enamel coated

[@danyk666]

The enamel is not enough for safety. Enamel insulates one turn from another, but the core must always be insulated from wire by something like transformer paper or other safety insulation.

[@franktechniek]

nebnoswel The enamel coating is very thin and fragile. When he slides the primary coil back into the core, one side has the paper removed. There is a good chance of scratching of some enamel and causing some short between the primary and core. Sure there is also a good chance of getting away with it, but I'd rather put some insulation in place and making sure it is safe.

[@Appregator]

Not if you use silicone rubber covered wire which is what it appears to be. Nevertheless I would still slide in a high temp strip of lagging or electrical cardboard just for extra safety.

[@tinkerbit]

The shorter the best. If you see pro spot welding machines photos, they have the electrodes very near to the trafo. My example has too much cable. If I had to use it a lot, perhaps I would shorten it.

[@tinkerbit]

Secondary, the wire is much thinner. You can cut it with an utility knife. Do several cuts and draw the cut wires with pliers. Cut again and draw, and so on.

[@1b9m9x3]

where do you get these magnets? I'm interested on using the coil for making a levitation bed for an experiment - Lenz law

[@JahanZeb1976]

You didn't care of the primary insulation while putting winding on core. This is dealing with 220V supply, caution is a must to insulate it properly otherwise it could kill!

[@JahanZeb1976]

+Mark Schulz IV Yes this is normally the case. A good winding job consists nice insulation. Insulation is same or of importance as of conductance is!

+LearningZone The wire is insulated. Just looks bare. Transformers are made with clear insulation to save space, and for efficient operation,

[@JahanZeb1976]

+old guy Yes I know winding wires are enameled insulated but we are never every putting them without paper lining in metal core. Otherwise there is a chance of core to wires contact which leads to short circuit. I will upload a video soon on my channel covering this subject. Regards,

This may sound like a stupid question but how is that much amperage not flipping a circuit breaker?

[@125varma]

Hey guys, why in home heaters we don't use low voltage at high current? I mean something like 1.5 volts at 66 amps for example. I think this method of using 100W will generate much more heat than if we would run 240 volts at 0.41 W (100W again). Am I correct? :)

Don't you risk overloading the input when doing this or does the transformer current limit.
