• # question_answer The voltage-current characteristics of a DC generator for arc welding is a straight line between an open circuit voltage of 80 V and short-circuit current of 300 A. The generator settings for maximum arc power will be: A) 80 V and 150 A B) 40 V and 300 AC) 40 V and 150 V D) V and 300 A

$V={{V}_{0}}\left( 1-\frac{I}{{{I}_{s}}} \right)=80\left( 1-\frac{I}{300} \right)$ For V = 40 V 40= $80\left( 1-\frac{I}{300} \right)$ I = 150 A
