5.8 Other
signals
5.8.1
JOB pre-selection
Permits the specification of welding tasks (JOBs) by the machine. With the signal not set, the setting of
the JOB must be carried out via another control (e.g. M31x). With an active signal the setting of the JOB
is transferred (signal is automatically set in some actuation profiles and is not then visible in the profile).
5.8.2
Program pre-selection
Permits the specification of power stages defined by the machine. If the signal is set, a power stage is
pre-selected in accordance with the specification from the Program (special feature with program 0, see
Program mode chapter). With a signal not set, program 1 is permanently set by the control (signal is
automatically set in some actuation profiles and is not then visible in the profile).
5.8.3
Acknowledge error
An active error is reset using this signal. For a correct function, the signal must be sloped.
Not all errors need to be acknowledged; some events reset themselves automatically (see also the
error list in chapter “Error messages on the system “).
5.8.4
Gas test 1
Allows the shielding gas to be activated/deactivated manually. The signal can only be issued when the
system is at a standstill (exception: extended control signal operation). The signal can be used to extend
the gas pre-flow duration programmed permanently in the job, or to control it manually.
5.8.5
Wire Inching
Manual activation of the main wire feed for inching the welding wire into the tube/torch package. Signal
can only be issued when the system is at a standstill. Before activation any “reverse wire inching” signal
present must be cleared.
5.8.6
Reverse wire inching
Permits the retraction of the wire; can only be switched over when the system is at a standstill. Before
activation, the “Wire inching” needs to be cleared.
5.8.7
Cold wire on
In TETRIX systems with cold wire equipment, the cold wire is started with this signal.
The signal can be used together with the nominal value in control signal mode to create separate inching
functions.
5.8.8
Start auxiliary process
Starts an auxiliary process where applicable. To initiate the start signal, set the “Robot ready” signal first.
5.8.9
Position search
This signal is used in combination with a soft-collision detection of the welding torch (torch tube) with the
workpiece. With an active signal, a touch of the workpiece is detected. The detection functions only in
non-welding operation (see also chapter “Position search”).
5.8.10 Blow out torch
Allows a secondary gas to be activated/deactivated manually (compressed air is normally used to blow
out the torch). The signal can only be issued when the system is at a standstill.
5.8.11 Robot ready
Ready for operation signal for indicating the positioning device on the welding power source. Signal must
be set before the start of welding (see also chapter “Process fast shut-down”).
