4.5.2 Touch tool
Two alternative touch tools can be used for touch sensing
(see
Figure 4.21, "Welding wire used as touch tool"
Figure 4.22, "Gas nozzle used as touch
tool is the welding wire (welding plus). Sometimes the
welding wire is not accurate enough. The tip of the welding
wire can bend resulting in incorrect position information.
In that case the gas nozzle can be used instead. Using the
gas nozzle requires extra wiring from wire feeder's 10-pole
peripheral connector (pin F) to the gas nozzle.
The touch tool can be forced by the configuration in both
the web user interface and the setup panel, or the selection
can be allowed to be managed by the robot controller by
using the digital robot interface. See
"Configuring touch tool"
for more information on these
alternatives.

4.5.3 Fast status output
The fast status output is a direct hardware output for
systems where the latency between the sensing and the
detection status reception is an issue. The normal latency
is around 10 milliseconds through the fieldbus. The
response time of the fast output is about 1.5 milliseconds.
See the
configuring the fast output.
4.5.4 Selecting output voltage
The output voltage of the touch sensor power source can
be selected by using either the web user interface or the
setup panel. Setting the voltage requires
privileges.
