In a welder transformer
 
Hello Mr radio
That's ok, well explanation about what do to use it?

I need this transformer to make a welder the input voltage is 220v and the output is 108v and58 v but in 58 volt is has no amperage

May I ask what experience you have with electronics because creating a welder with a transformer can be quite dangerous. I haven’t done it but I have learned about the danger when I wanted to make one.

I finished the welder but i have somme issues on the input voltage is to hight is 143 volt
 
I have both practical and theoretical experience on welder stuff.. So I need to ask you some question about your present transformer

I have also putet a bridger rectifier

On the contrary your transformer is 220/110 step down/step up. It has 4 block of coils.. Each with voltage rate of approximately 55V ... Therefore with this parameters you can only have secondary output of minimum 73V.. By taking 3 block and put them in series and also isolating the 4th coil connection to be the secondary... You will have 220V input 73V output and probably 20-30% duty cycle.. What can u weld with this high voltage of 73V care must be taking operating with such high voltage.. And remember the current might be lower than expected.. You can increase that by changing the secondary winding with a 2X size of the original coil and half the turns then you will get 2* your current and the voltage drod to half.(31.5V) thanks
