A continuous supply of 30 v and 200A is used in a arc -welding of carbon steel to produce weld bead of 40mm^2 cross sectional area . Carbon steel requires specific energy 12 J/mm^3 for melting . Electrode material required the same specific energy . For the welding speed of 10.25mm/s , calculate the melting effencency.
