[MW:1671] Re: voltage

Hi Nilesh,

 

The voltage before striking the arc is called open circuit voltage. and once we strike the arc, the current increases, voltage decreases and after that arc is maintained at sufficient arc gap and the voltage is termed as arc voltage.

 

Normally arc voltage during SMAW welding is kept at 24-27 volts and OCV shall not be higher.

Dea All,

 

            I want to know what happens to the voltage when we strike the arc.Is it drops to zero and then gradually increases.

 

thanks
