Function
Description
0
0
Weld start
The value 1 signals that the welding start mode is active.
Has no effect when wire feed or wire retraction are
performed.
0
1
Wire feed
The value 1 signals that the wire feed or wire retraction
mode is active. If wire feed and wire retraction are set to 1,
no process is performed. Wire feed and wire retraction are
not performed when the welding start mode is active.
0
2
Wire retraction
0
3
Gas flow
The value 1 signals that gas rinsing is active. Shielding gas
is discharged at the start of welding regardless of whether
gas discharge is activated/deactivated.
0
4
Component search The weld detection function with an auxiliary current is
activated when this value is set to 1. Has no effect during
weld start. In addition, the weld start has priority over the
component search.
After the welding process is complete, the function is used to
detect burned-on wire.
0
7
Watchdog
Used as a watchdog signal. This bit must alternate between
0 and 1 every 0.5 seconds. If the watchdog signal is not
active, only operating stop data is accepted.
If this bit does not change for more than 1 second, a device
fault stop occurs. If the watchdog signal is not active when
the welding machine is started or when the welding
machine is restarted after a fault stop, the welding machine
issues a warning and no new fault stop occurs. The warning
is canceled when the watchdog signal is active again.
1
7
Operation stop/
reset fault
The value 1 indicates that the operation of the device has
been stopped and the fault code is reset with E 000. When
1 is reset to 0, faults and warnings are cleared and
operation of the device continues. Device system faults and
control voltage errors cannot be reset. In such cases, the
power supply to the device must be switched off and on
again.

Save location
number for welding
condition
(job memory)
Is set if the memory function for welding conditions
(job memory) is used.
7.6 Managing the job memory on page EN
If this function is not used, the value is set to 0.
By setting a save location number for welding conditions
that is between 1 and 100, the corresponding stored
welding condition of that number is set to the input data
from offset 4 to 29. The stored welding condition can be
checked, but this does not load it.
By setting the save location number to 0, the input data from
offset 4 to 29 is reset to the currently activated setting.

0
Load job memory Setting "Load job memory" to 1 loads the welding condition
of the number that is set as the save location number.
However, it is important to note that when setting the
permission to change settings from offset 3/bit 7 to 1
immediately after loading the welding condition, the setting
values for offset 4 and higher will be applied as currently
activated settings. To load the job memory, the permission to
change settings is normally set to 0.
If "Load job memory" and "Write job memory" are set to 1,
both processes are disabled.
