Description Data Type Parameter
This parameter is only used in JobMode. It spe-
cifies if the robot controller or the power source
job controls preflow and postflow of shielding gas.
The following values are available:
• Robot
• PowerSource
Robot means that the robot controller is in charge
of the gas flow control. The configurations in the
power source job are discarded.
string Pre-Post Flow Control
PowerSource means that the values in the power
source job control preflow and postflow of the
shielding gas.
If
PowerSource is selected, the value for “Ignition
timeout” has to be set to a bigger value than the
preflow time in the job, and the “Weld Off
Timeout” must be bigger than the post flow time.
Default value:
Robot
When the arc is ignited, the seam will generally
not have reached the correct temperature. Pre-
heating can thus be used at the start of the weld
to define higher weld data values. The values to
be used are. If the preheating parameter is
changed, the contents of seamdata will also
change bool Heat on
Default value: FALSE
Specifies if the heat phase should use the seam-
data parameters heat_time or heat_distance.
TRUE means that heat_time is used and visible
in the seamdata. FALSE means that heat_distance
and heat_speed is used and visible in the seam-
data. bool Heat defined as time
Default value: FALSE
Enables masking of cool_time component in
seamdata.
Default value:
FALSE
bool Cool time on
Specifies whether a crater fill is to be used in the
final phase. This means that the end crater that
can form in the completed weld will be filled in
with extra filler material. If the Crater fill parameter
is changed, the contents of seamdata will also
change. bool Fill on
Default value: FALSE
Delays the power control signal with this time
(seconds). This gives the analog reference signals
and group output signals enough time to stabilize
before the weld is started. num Arc Preset
Default value: 0
The maximum time (in seconds) permitted for ig-
niting the welding arc. num Ignition Timeout
Default value: 3
The maximum time (in seconds) permitted for
shutting off the welding arc. num Weld off timeout
Default value: 10
