6.2.7 WeldingMemoryChannel
This 8-bit function represents the currently active memory
channel.
• The minimum value is 0.
• The maximum value is 199.
• The minimum step is 1.
6.2.8 TAST
This 16-bit function value represents the deviation of the
welding head from the groove during TAST (through-arc
seam tracking) operation. A lower value indicates greater
distance from the groove. The value is equivalent to the
welding current and is valid for all processes.
• The minimum value is 0.
• The maximum (theoretical) value is 6500.
• The minimum step is 1.

6.2.9 WeldingProcess

This 8-bit function value represents the current welding
process in use. The value is an enumeration and can be
one of the following values:
• 0 = Unknown process
• 1 = MIG
• 2 = 1-MIG
• 3 = Pulse MIG
• 4 = Double pulse MIG
• 11 = WiseRoot+
• 14 = WiseThin+

6.2.10 Ready

This signal function indicates readiness of the welding
system. The main power supply must be turned on, the
system software booted up, and the system bus properly
connected. The system is assumed to be ready when a
power source and a wire feeder are found on the system
bus, there is at least one user interface (excluding the web
user interface ) available, and there are no active errors in
the system. If the user identification system is in use, a user
must be logged in.
• 0 = Welding system not ready. Check that a user
has logged in, all devices are connected properly
and errors are resolved.
• 1 = Welding system ready

6.2.11 PowerSourceReady

This signal function indicates the status of the power
source. The power source is ready to start welding when it
is not currently in use, when the robot has not requested
welding start, and when crater fill is not active.
• 0 = Power source not ready yet for a new arc start
• 1 = Power source ready

6.2.12 CoolingUnitOk

This signal function indicates the status of the cooling
unit. If there is an error in the cooling unit, the signal status
changes and a cooling unit error will be indicated in the
system.
• 0 = Cooling unit error
• 1 = Cooling unit OK

6.2.13 ProgramSaved

Saving the parameters takes a while in the system. This
signal function is cleared at the beginning of the save
process and set after completion. The signal reacts (goes
off ) when a save operation lasts longer than 150 ms.
• 0 = Saving new parameters
• 1 = Save operation ready

6.2.14 RobotHasControl

This signal function indicates the online control status. The
value is copied from the
robot.
• 0 = Robot has released full control to the welding
system
• 1 = Robot has control over wire feed speed,
voltage, fine tuning, and dynamics values

6.2.15 CycleOn

This signal function indicates the status of the welding
cycle. The welding cycle starts at the beginning of the
pre-gas phase and ends at the end of the post-gas phase.
The signal indicates to the robot when it is safe to move
to the next position. However, the welding cycle does not
prevent starting of a new weld – a weld can be started
during the post-gas time.
• 0 = Welding cycle not active
• 1 = Welding cycle in progress
