Constant Current (CC) type power source
Constant current characteristics are also called as drooping characteristics. Typical V/I curve of such
Power source is shown below. Here the current remains stable even if the arc length varies. When
There is change in arc length, change in the voltage is more when compared to change in current and
hence they are called constant current type power source
Relationship between the voltage and current for different process in CC type power source is as under
SMAW:
V = I * 0.4 + 20
GTAW:
V = I * 0.4 + 10
Constant Voltage (CV) type power source
Constant voltage characteristics are also called as Flat characteristics. Typical V/I curve of such power source is
shown below. Here the voltage remains stable even if the arc length varies. When there is change in arc length,
change in the current is more when compared to change in voltage and hence they are called constant voltage type
