Answer / k.n.kumar

in arc welding we use differential compound generator
because of it drooping charecterstics

Answer / madhusudhana

The generator used in welding purposes should have high
current and low voltage which can be obtained by
differential compound generator. You dont get low voltage on
high current for a dc shunt generator.

Answer / ravi teja.a

Dear K.n.kumar,

why cant we use DC shunt generator as it is
also having the drooping characteristics on load.Please
explain in details if it is not used in that
place???????????

Answer / piyusa bal

In welding there is differencial compound generator is use.its for her drouping cher.he produce high current and low voltage and thats i need for

Answer / ankit tiwari

In welding process higher no load voltage is required to iniate the arc,after the arc is initiated lesser voltage is required to maintain the arc.it is only given by only differential compound generator.
