5.4.4.2 RTFLC-2 hollow wrist system with Helix cable assembly
Connecting the nozzle sense function
If the robot control provides a control circuit for nozzle sense functionality.
The connection is accomplished with a 1-wire connection (green) to the nozzle sense circuit
in the robot control (5), see illustration below.
Usually, the control cable will be directly connected to the wire feeder. See the
manufacturer's documentation for details. The link to the robot control is then implemented
via the power source robot interface.
Rating of the control circuit: max. 50 V / 5 A.
PERICOL!
If the nozzle sense function is not being used, the open end of the control cable on
the power source connection side must be properly isolated in order to avoid short
circuits. During certain problems on the torch head, the full welding potential may be
present on this cable.
ATENȚIE!
After detection of contact (gas nozzle on work piece), quickly reduce or cut off the
maximum current in the nozzle sense circuit in order to avoid overloading of the
system.
Allowed load max. 1 minute at the rated nominal current.

5.5 Torch installation
Be sure to use the correct version of the torch mount and cable assembly (water or gas
cooled).
5.5.1 Torch neck equipment
The torch neck, see (1) in the illustration below, must always be equipped to suit the wire
diameter and material.
