Hi edu,

I am not sure exactly what you are looking for but let’s try this one:

Thanks Ante for answer,exactly is the circuit but is a really difficult schematics,its there anyone more simply ;D ;D ;D,

Regards .Edu

Hi Edu,

Well, a switcher is much more complicated than any”normal” transformer welder. You might consider a standard transformer circuit maybe? I think I got a link somewhere if it would help you. Are you going to try to build a welder or is it just curiosity? ;D

Hello Ante,
I am interested in Arc welding circuitry could you tell me the resources where can i fine it.
My current requirement is 200 A .
If you have any idea please guide me i want to implement Arc welding.

Hi arunava,

There are different kinds of arc welding, which kind are you looking for!

Thanks again Ante:

i looking to build a welder in little series , for home uses lightweight, the transformer method is heavy to carry.....
I see a few european commercial products but in my country (argentina) are very very expensive.....

Thanks in advance for any help......Edua

Hi Edua,

The light-weight welders are as you pointed out earlier much more complicated. They are also sensitive in construction, easy to get something wrong in layout and control. The common light-weight “stick” welders are quite expensive compared to transformer type here too. The prize ratio is about 6 : 1, this is due to the complex technique and some of the delicate expensive components.
