Why didn't you used 10mm dc single core insulated cable with more of 5 or 6 turns of each transformer then it could stick hard.. thanks good video keep making good videos

Well done, but not in the know that the battery can not be heated categorically?

I take the same view as the previous speakers

You are correct. He does not have enough power flowing to the work. He also needs to rewire the transformers correctly.

I totally agree, welding time should be around 0.1 second or preferably even less. You need very high current (at low voltage).

I totally agree, this device definitely heats up batteries too much 1v is totally not enough for those thin wires. + Using cheap spot welding timer makes things a lot easier and safer One that I made a long time ago has 1.4v with really thick wires directly coming from transformer. And It still needs to have 7x20ms time, which is a lot in my opinion. You need to have 2-5v voltage (with 1200w transformer) with dual pulse control to have it make proper welds on batteries.

Thanks 😁

Well I agree with you

You need very high current in order to weld, many hundreds of Amps. This can only be accomplished by converting to low voltage.

I cannot understand the output connection. It is not parrallel nor series. It is a wrong connection that is why the current output is very small. There are two transformers and could have easily handled eveen 1/8 welding electrode.

what? 🤔

@@BalkanHandyman Pusiste las bobinas secundarias conectadas en serie. Deberías haberlas conectado en paralelo si la idea era conectar los dos transformadores para tener más Amperes.

That's are microwave transformers 220v primary, secondary was removed and put that white cable, after some time I buy that big black cable and change, remove white put black

Make Stuff with Little Devil Two questions maybe you can help. I am building a spot welder that requires one of these transformers. It appears about the same size as you have there. I notice that you removed the insulation on the inside walls where your secondary coil was. Most others ive seen kept the secondary coil insulation in tact. On mine, i accidently removed the insulation while removing the secondary coil. 1st question....should i insulate the inside walls where the secondary coil was? With maybe electrical tape? 2nd question...... my welding cable is 32mm. Most others used 35mm. Is the 32mm sufficiant? Thanks in advance.

1. you don't need that insulation, you just need metal plate between primary and secondary 2. yes it is sufficient for spot welding 3. thanks for watching my video 😁😁😁

Make Stuff with Little Devil awsome! Thanks for the quick reply! Great video. Yes, the metal shunts are completely intact. Thanks again.

if you have a 15 volt ac transfromer could you hook it up too a mot transfromer and have it put out 270 volts.. so what im saying is 100 too 15 volt too the mot transfromer would it push out 270 volts?

If I understand, you need 270V primary and 15V secondary, or you want 15V primary and 270V secondary???

what power you use, 110V or 220V?

110 here in canada im trying too cheap out on a step up transformer an have crap loads of little trans fromers and crap load of mot ones i havent touch yet so .. what i ment as take 15volt dc adpater remover the board it be 15 volt ac.. and ifi hook it up too mot transfromer ..so would the out put be 270? or would it even run the mot transformer right

try putting the outputs...in phase,,, in series....will be much snappier.....if you want, add a 100 amp bridge rectifier for a DC output....

Jay Obrine, How can they be out of face if the input and the output is connected in parallel?

If you had wired the 2 transformers in series then it would act as one transformer having only one sine wave with double the voltage and half the wattage coming out. You would still have to pay attention to the wring connections to have the desired voltage. With 2 transformers in parallel you have 2 sine waves to deal with. If the windings or the connections of 2 AC transformer are wired different then the peak (+ voltage) and the trough (- voltage) of the AC current are not the same at the same time (in phase). Even the directions of the windings can have an effect. The further out of phase (out of alignment one sine wave is to the other) the more one wave cancels out the other. If the out of phase sine wave (the cosine) is 180 degrees out of phase than the result can be a complete cancellation of each other. Remember that transformers that appear to be the same (from the same manufacturers with the same specs) will still have some variances.

I just reviewed the video and noticed at time line 1:56 (paused) that the wires to the secondary windings are also crossed. Since both the wires to the primary and the secondary are crossed the effect is canceled out. This would make the 2 transformers seem to be wire correctly in a parallel fashion. How ever, this still leaves the magnetic flux flowing the opposite directions in the transformers. The primary windings should be wound the same in both transformers, but the AC input is wired to opposing tabs, leaving the flux flowing in the opposite directions within the transformers. If the flux was flowing the same directions it would improve the end results.

after two months: What do you suggest? What is the right connection for the best performance?

🤔

😁

Best is 1 - 1.2 V and 500+ Amp

What does 25mm2 means

@@Naqshbandi1112 Wire cross-sectional area, its actually 25mm² though. Useful to know, since the amount of current the wire is able to carry is closely related to this number (although electrons are mostly conducted along the surface of the copper and so the number of strands is also important).
