Constant Current (CC) type power source
Constant current characteristics is 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 * 0.04 + 20
GTAW:
V = I * 0.04 + 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 power source
