13.2.2
Adjustment of Hot Characteristics
The following parameters change the hot characteristics before transition to the main current
after the first arc start at ARCON signal.
Parameter
No.
Meaning
Guideline of Adjustment
P05
Average current of hot char-
acteristics to stabilize the mol-
ten pool
-For excessive arc burning;
Increase the value.
-For excessive repelling;
Decrease the value.
P06
Average voltage of hot char-
acteristics to stabilize the mol-
ten pool
-For excessive repelling;
Increase the value.
-For excessive arc burning;
Decrease the value.
P07
Output time of hot character-
istics to stabilize the molten
pool
-When taking time to stabilize arc;
Increase the value.
-For burn-through at start point;
Decrease the value.
P43
Transition time from hot char-
acteristics to main welding
characteristics
-When taking time to stabilize arc:
Increase the value.
-For burn-through at start point:
Decrease the value.
