CURRENT PROFILE
Selection of the welding current profile.
You can select between:
-
Single weld (standard) or
-
Seam (option).
TRIGGER SOURCE
Measuring is started in the case of a
current trigger by the set current range
end value when the trigger is reached.
Measuring is started in the case of a force
trigger by the set force/pressure range
end value when the trigger is reached.
The trigger is actuated in the event of
0 displacement if a signal is active at
“Zero penetration 1 or 2” the hardware
input (X38).
TRIGGER
The value in field TRIGGER determines the
current / the force %-value that must be
input in order to start the measuring
process.
The range can be set between 0 to 100
related to the upper limit of the effective
range.
Recommended setting: 4.0
At inverter < 1.0 %.
I-FALL LEVEL
Specifies the value of falling current in % of
Is to which the on-time tw is counted.
MEAS. TIME
For single weld measurement, you need to
set a bigger value of the welding control
total current time here.
Depending on current source connected,
the total current time can also result from
the total of single pulses and intervals.
Setting range
AC: 0 to 5000 ms
DC: 0 to 2000 ms
DELAY
Option
CURRENT TYPE
Set type of current of welding current
source here.
DC for direct current sources
AC for alternating current sources
