Default Can someone translate this cyrillic

Hi All

I think here are also russian guys.

I have a question not related to audio but a power converter for welding.

It is cyrillic and I like if someone can translate it in english for me, or dutch.

I can not see for shure what to do with transformer winding etc, and it is high power so need a good translation, so my russian friend I thank you already.

regards

kees

Would scanning the picture and using OCR software (optical character recognition) work.

You could then get the text off the circuit as a text file and copy and paste into google translate. No idea if it would work or not but worth a play maybe.

Mooly's suggestion is excellent (why doesn't it surprise me?)
I snipped text parts out of the schematic, such as what's attached,
then
OCR'd it at
Free online OCR
and pasted Cyrillic text in Google translate, result was:
welding apparatus
Current 5 - 165 A
Electrodes up to 4 mm
2005

Do it part by part.

Don't waste time on single letters, you already know (or should) the "B" is "V" , "P" is "R" and so on.

That said, what are you trying to do?
If repairing such machine, the schematic will do; if trying to clone one, forget it.
The transformers shown are custom wound and there is no data on the schematic about them, not even voltages, current or anything else.
The machine is basically an SMPS, where you can get from (estimated) 15 to 60V or thereabouts and current (rated) from 5 to 160A.
I know, I weld myself.
In fact, they state it's enough for 4mm electrodes; personally with 160A I would be happy with up to 2.5mm ones; 3 mm as a limit.
4 mm ones will drive you crazy, sticking every few minutes because they will not become hot enough.
You *can* weld with them, but you'll need a surgeon's firm hand.

That said, the big problem will be Tr3 , the output one, and the choke Dr1.
Anyway, good luck

Wel like I say it is already translated, the trafo can be made myself easely.

I do not use electrodes I do use welding wire in a Co2 welder who has a died trafo, I do use this
inverter for that instead, I go build this pcb into the Co2 welder housing, I have not a repair, I can read schematics, not a problem.
I now SMPS I repear a lot of that supplys even the computer ones, I go make a pcb for this.

1. Title (in the middle): Welding machine ; Current 5-165A ; electrode up to 4mm ; 2005
2. various text in the schematic: (middle left): "регулировка тока" - current regulator ;
(middle right , (+) and (-) ): "к электродам" - to electrodes ;
(bottom left): "датчики на замыкание при 90 гр." - short circuit sensor at 90 degr. ; (green LED): "работа" - operating ; (red LED): "останов по перегреву" - stop due to excessive heat ; (yellow LED): "нагрев" - heating ;
text near transistors KT814 and KT805: temperature sensor for automatic fan speed control.
The remaining Text at bottom right is description of the transformers.
"витков" - number of windings (for each coil) ; "ПЭВ" is the name of the wire used (actually this is a standard copper wire for transformers), followed by its thickness in mm. ; "Зазор" - gap (air gap).
Transformer number 3 is a bit different than the other - 1st coil (primary, I ) is 18 windings of 5x1.2mm flat wire ; 2nd coil (secondary, II) is 6 windings of 65x0.5mm flat wire, as far as I understand they recommend winding it on top of the primary one, on the whole width of the bobbin.

"Др1" - steel, gap 5mm, 18 windings of flat copper wire 0.6x40mm, ~70-90uH
The steel is from the type shown here: Магнитопроводы ШЛ | Броневые | Магнитопроводы | "ТорТранс" - производство трансформаторов, автотрансформаторов, дросселей, преобразователей напряжения, купить трансформатор, сердечники.

"Тт" is a toroid (actually two) size 20x10x5mm , 100 windings 0.2mm

Other symbols: "в"=V ; "вт"=W (watt) ; "мк"="мкф"=uF

I hope my translation will be of some help to you.







regards

It will be ready for working, only the wire on the ferrite E55 core has to be 90 x 0.2 mm and 65 x 0.2 mm litze wire who i have to make myself.
