One transformer is a little bit to weak and also 14V is too low to support the arc reliably. Make 2 - 4 transformers and also make voltage about 35V at least It will be easier to work with.
It takes at least 35-40 volts to properly strike the electric arc. 45 volts or more is ideal.
My old Lincoln says 24v arc output. Running 2 car batteries in series would do way better than this.
Reduce your winding (yellow wire) so that you will have more current and lesser voltage. Use the smallest possible welding electrode, say 3/32. 1/8 will not work.
how about reversing polarity?
@@commonconservative7551 reversing won't help.
What size of cable do you use
@@boyevangelista2661 you have to realize smarter people than [us]- have with .>greed tried, to get cheaper energy and failed
@@boyevangelista2661: it's a 220 V 200 ampere as the blogs says. Welding cable/s depend on the current, so choose a cable which has the rating of 200 amps. There's a table for size vs amperes, or better still go to them electrical store... and ask. Sometimes, it is printed on the cable itself.
With high temperature 12 gauge wires (~2.38 mm), you should get approximately 30 turns for the secondary coil. Any wire with insulation rated at 300°C will make the DIY welder easier and last much longer.
This sort of thing is useful amn having a plug and play arc welder in household electric board and weld is breakthrough stuff. The real deal is contacting welding rod manufacturers and asking them to make the mirco rods you need to weld things with this set up. So my advice make a micro welding collect data amps volts and contact welding rod manufacturers and get them to make the rods and then test it out. It could become a household item or device for millions of people who like to mircoweld things up
Very good idea. The only problem is that a microwave transformer has a power of just over 1000 Watts while ARC welding inverters usually have around 4000 Watts. This limits soldering to small parts. But associating two transformers can double the power. To do this, just make two equal sets and connect the output wires in series (for no doubt, join one of the wires from one set to a wire from the other set and the output will be the two remaining wires, like this: out1 -- o --- o -- out 2) . A multimeter or an AC voltmeter should be used to verify that one is not inverted as follows: each set should provide an open voltage of approximately 30 volts AC. After connecting in series, the output voltage must be the sum of the voltages of the two sets, if it is the difference, invert the wires of one of them. The ideal open voltage for ARC welding is approximately 50 to 60 volts. If it is larger, thicker wires with fewer turns must be used in each transformer, which increases the current capacity and decreases the voltage. And, as shown in the video, always check the heating of the windings of the two transformers, eventually interrupting the use until they get colder. In this case a fan can be useful.
I am in Canada. By default home power is 110 v. If you want to use 110 how could you do this
@@DanielJAudette Turns out any of the microwave transformer welding projects are going to be difficult with the lower primary voltage. Currents will be lower. It's almost impossible to find old microwave transformers with a 230 primary winding, even on ebay. I would have thought it a bit easier in Canada because I believe parts of Western Canada still use 220volt household. In the US we use 240/120 volt 3 wire as the residential standard. Typical appliances are all 120 volt. But wiring a dedicated 240volt circuit for these welders would be the easiest solution, if you can find the transformers. It's the turns ratio of primary to secondary that makes this work effectively. There's a few tricks you can use like less windings in the secondary. This helps a bit and I have built a decent spot welder for light gauge stuff. May be building a two transformer version that should be better running it on 240 volts.
His stick welder here is garbage though. No matter what he does, it will lack penetration to make real welds.
Connecting transformers in series will not increase current strength but will double the voltage,.. current stays the same, parallel connection will double the current strength but voltage level stays the same Sir🤗
@@simanga999 Connect the primaries in parallel but run the secondary cable in series through each transformer. You are correct in that the current will not be raised but the voltage will double if the transformers are the same and the secondary wraps are equal to each other. (they must be in phase with each other so they add and not buck).
What this will do is increase the voltage and the total power being dissipated in the arc. So about double the power with the same current. On the Primary side, the total current for the two parallel primaries will be double. Instead of about 1000 watts it will be 2000 watts. The higher voltage will carry the arc better.
You can connect multiple transformers this way with parallel primaries and series secondaries. You can end up with something close to a small welder output. Not great and not very efficient.
1/16" rod and about 4 more turns on secondary would produce better results.
Secondary moving around like that will cause wear on insulation and possible short circuit. Tighter winding of secondary and packing core as full as you can get it would yield a tighter, more stable transformer. You're getting about 1 volt per turn on your secondary and the best results I've had has been above 23 volts with 1/16" rods.
BTW, in case you don't realize it zinc poisoning is a real concern!
In this video I learnt
Two things they are:
1)welding
2)battery charger
I impressed ..because your videos are more infermative
ohh excelente amigo muy buen proyecto!!! lo felicito...y gracias por compartir tus ideas..
No da 200 amperios ese tranformador yo creo que ni 100 amperios se pega mucho el electrodo
El núcleo es demasiado pequeño.
Very interesting video, maybe be good for sheetmetal work with very small electrodes. looks like this going to be my weekend project. Thanks
I'm going to show you how to make a velding machine from a microwave transformer...but first I'll melt some solder and a plastic vall anchor before rewinding the secondary coil to get the proper power output.
Mr. Election... Your projects are innovative and informative...!!! Ensure that in every video, you elaborately explain the safety procedures,which is mandatory....!!! 👍😃
بسیار ممنون ومتشکرم از شرح وتوضیح خوب ترانسفورمر 🙏🙏🙏🙏👌👌👌👌👌
Very good project
Your videos are all fantastic! Thanks!
Thanks 😃😃😊
I have seen on UA-cam someone made a welding machine with two transformers linked in series with a thicker wire through the secondary winding.
This is a magical all in one device...!
Now I know how to make a beefy soldering iron 💪 :) :)
Thank you for your very informative video
Just what I needed I got to dismantle my mother's microwave byeeee
Simple n clear voice...👍👍
simple but not show the connect wire
Yeah apart from Vuelding!! 😂
i like your experimet, because yu only need one transformer and other personas using two or tree transformers, you are one persons whit many ingenius, congratulations
Also remember that the primary coils have to be connected un parallel I mean the same pin in each side left with left and right with right, when use more than one transformers and the secondary in serie..
i was wondering if i could make a crude induction heater with this. will running 50VAC through a coil make it behave like an induction heater?
Your welder is out putting around 45-40 amps as expected by its size and volume
Probably about 10-12 wraps of slightly thicker wire cable for the secondary
Cool video. If you have a 220v output from your wall/panel you would weld I think.
Ver y good this video friend
You're some genius trying to weld rust
Super.. Good job.. 👍👍...
Nice DIY machine,
You definitely don't want to charge a battery with AC 😂🧨
What will I use all these diodes for now
Buddy you need to spread the load on multiple transformers because your welder won't last long since the wire you used to make the secondary plus the mass of the transformer isn't enaugh to handle more that 30 amps.
Next time try with 4 MOTs and on the secondarys use 8 turns of 4.5-5.5mm copper wire per transformer connected in series!
If you need any help just PM me I have the full component mosule board I can send to you
You can build it but definitely can’t use it😂😂😂😂
Bro can you plz tell me the thickness or the no. Of the welding electrode you are using
Niceeeeee
Cuántas vueltas le diste al secundario con el cable de amarillo??
رائع تحياتي لك تابع محتواك جميل
it can work better with an electrode o 1 mm. another idea is to connect a big capacitor of 40 volts in paralell in the low voltaje circuit
Esta bueno para una alarma bibra perfect
Hi,I tried using stabilizer transformer,but I am stuck at the first place,which is knowing the secondary coil for the winding.
There is a welding machine made by a Russian man who cut out secondary winding of two transformers and linked the transformers unside-down to make bigger gap for the secondary winding and wound a bigger and thicker wire as the secondary winding and made a professional grade, portable welding machine, giving results equal to a commercial welding machine.
Would you put its URL here pls!?
My Compliments Master E!
Personally I would use two transformers and link them in parallel. It would give you a more consistent reaction and a cleaner faster weld.
bro i use 3 transfarmer and out put 42volts but not welding plz support me .
I do support you my friend, I admire all who recycle old machinery and electronics to make new stuff. I do it myself. Perhaps your transformers are past there prime. I’ve seen people do this sort of thing before with success using only two transformers. Alternatively two car batteries are good for welding.
@@mutley245 what is the desired voltage and amperage
I hope this guy is on a no fly list.
Nice👍
use 2 "E" shaped cores with one primary winding, and you will have more space for the secondary winding. Up to 45 volts. tight lawyers
Transformador microw para soldador de barillas de 3 2 mm magnifico gracis
Para quienes solo tengan un transformador pueden cortar la soldadura en partes más pequenas y pueden tener mejores resultados
gracias
Sir microwave transformar is only suitable or any other transformar is ok or not plz replay mee
Esta solda de com transfirmador e uma memtira ja tentei tidos tipo de cabo nao oassa energia a nai ser que eles liga um fio fora destes cabos
Can I use a 6 SQ mm wire for the the project
Sir i have home inverter transformer connected with capacitor should I remove capacitor or is it ok without removing capacitor to make welding machine
Can u tell how much meter wire used for this?
I have old transformer so i want to buy wire
Is it possible to make welding transformer using UPS transformer?
You need at least 24 bolts to weld properly, so one transformers it's not enough maybe 2 or 3 conect the secondary coils in serie using number 10 gouge eh taken at least 12 bolts per each transformers in DA secondary coil, end this sort of welding machine s can no ve use for more that 10 minutes or the primary coil will crash.. If you want more time in use, you have to connect more transformers,
A square wave input
should increase the
efficiency & current.
Several ways to do it.
They make 1/16" E-6011,6013. Lincoln and Hobart have it. It's not listed I find it on line.
Your welder would burn 1/16" rod.
Isnt it dangerous now? After you change the coil?
Heloo you are sun shines and star beautiful. Very nice👌👌👌👌🙏🙏🙏🙏iam in iran meca tro nic and hedrolik👌👌👌❤❤❤
can i use 110 v microwave transformer for it
How to suply voltase sir?
hi> you should try connecting 4 of them together ,,,,,IN PHASE....= cumulative output of all....then you' ll weld.....use heavier wire as possible, with minimum thickness of insulation...and add a fan in a box to cool them. as the xfrmers add up, use heavier wire....your best output for ac weldings should be around 48 to 52 volts, ad approx 120 amps or more....done this....
روعه تسلم
14.4 voltage is okay, bu there will be arround 200 amp current also. You can't use this for battery charging.
te podría funcionar con los electrodos más finos, o agregándole capacitores a la salida, de unos 30 volts y 50 o 100 mf. para ese electrodo necesitás 2 trafos en paralelo a la entrada y en serie a la salida, unas 30 vueltas.
Una pregunta,como se cnectaria el capacitor?
the problem is is that rusty tube you first tried to weld is way too rusty to even try to weld with and those bolts are made of stainless steel which isnt easily weldable with a stick welder
Can I use 14 awg wire for winding?
Tharmal protactor must ? Plzz riplyy
Use rectifier secondary side, DC current welding is fine,
how bro
Con con dos transformadores vas a tener más Carriete estatlca para el arranque más rápido de la soldadura con conarco trece
You need one more transformer
how many amps of current can this coil hold?
I make beige rectifier from diode and connect With this transfermer to make battry charger but now rectifier is heating alot why?? please tell me
you'll get a better arc if you grind off the rust. 8*) also you need 30v to weld
Is there any videos with 120 volts instead of 220 volts
Why am i here at 3am
Con Cuantos Voltios
Trabaja
y Que Número De Alambre Usas Y Cuantas Vueltas
Cable de 4 mm y a 14 voltios
how about reversing the polarity?
It might of been a better spot welder just not enough voltage. Maybe 2 transformers. ?
Have you tried it with twotransformers. Am curious .
Надо два трансформатора как минимум, а лучше 4
remove magnetic shunt from secondary,that wil give yoy more power...and fill secondary with wire as muc as you can,to use more of transformer power
you need at least 40v to melt a welding electrode. the voltage you have there is only good for spot welding
i like very much your experiment, only i think you need soldadura 6030 very delgada, my inglis is nos good.
Make it 18 turns, and use one more transformer in series, u will get 37 volt. That would be perfect fo thiker metal.
Que calibre es el alambre?
Great DIY. But where are your safety gloves?
I have same did same like your 4mm wire with 15no. turn.. It's not able to melt electrode. I have even add 3 more transformers with same process.. Total 4 transformer... Still it's not working... Help me please.
deben ser dos para que el voltaje y corrientoe sea el correcto, intente hacerlo pero me pasaba lo mismo
if you use 2.5mm wire then you would have more turns= more voltage to strike the arc but still enough current
Hello Sir, I greet you for your video. I followed your example with my microwave transformer. But this produced no output voltage result. Indeed in secondary winding I used a 1.8mm cable of diameter with a length of 4 meters. When I connect the transformer to the current of the sector and that I measure the output voltage with my multimeter it is null! I was looking for 18v as output voltage to manufacture a charger of any type battery especially solar: GEL, AGM, acid please help me.
1.8mm is very thin.
It may melt the wire and you don't realize it yet.
It is 4mm in the video
You need at least one more transformer. 14 vac isnr near enough to strike a good arc
How many turns of primary coil
Nice👍🏻👍🏻 🇮🇳 || Kuki 13|03|2022
Any solution
you need to connect about 3 more transformers in series and you'll have a welding machine
what is the target voltage after connecting the 4 in series?
JUST Connect Transformers GALORE !! And WELD ! ANYTHING !!
You want to get rid of that yellow wire, in favor of that black wire. you want to be somewhere around 2 gauge, & just around two windings, is all you need. It needs to flow more current, & you've sacrificed the amperage, in favor of voltage with that yellow wire. I know. I build welders.
I just visit your channel
I think there's too much Rust on the part. Usually parts are cleaned and sand blasted because oxidation ruins welds.
From what I have heard.
