13.3
Adjustment of Arc End Characteristics
The following parameters change the characteristics from when ARCOF signal is input until
arc disappears.
Parameter
No.
Meaning
Guideline of Adjustment
P11
Average current for crater processing after
ARCOF signal is input
VALID
when D
parameter
D1-4=ON,
however
crater pro-
cessing
always
invalid at P
parameter
P13=10.
-When craters are not
filled;
Increase the value.
-When craters make
holes;
Decrease the value.
P12
Average voltage for crater processing after
ARCOF signal is input
P13
Crater processing time after ARCOF signal
P14
Average current to adjust the burning after welding
-When wire sticks to the
base metal;
Increase the value.
-When wire sticks to the
contact tip;
Decrease the value.
P15
Average voltage to adjust the burning after welding
P16
Arc time to adjust the burning after welding
P17
Peak current to adjust the spherical diameter of wire end
after welding
-When arc does not
start at next ARCON
signal;
Increase the value.
-When the wire is
repelled at next
ARCON signal;
Decrease the value.
P18
Peak time to adjust the spherical diameter of wire end after
welding
P20
Time to prevent the wire from sticking to the base metal
after welding
-When wire sticks to the
base metal;
Increase the value.
-When arc comes out to
the part other than the
welded spot at air-cut;
Decrease the value.
P44
Transition time from the main characteristics to the end
characteristics
(VALID when D parameter D1-4=ON, however crater pro-
cessing always invalid at P parameter P13=10.
-When craters are not
filled;
Increase the value.
-When craters make
holes;
Decrease the value.
