Migatronic RWF2 Betriebsanleitung Seite 8

Connection and operation
The RWF unit is supplied ready for use with Sigma in
2
both standard and robotic setups.
It is possible to connect up to two RWF
welding machine/power source, in which case the units
must be configured as numbers 1 and 2 respectively by
moving a jumper on the RWF
14). By default, the RWF

Wire inching forward/return
When idling, wire inching can be activated by pressing
one of the keys or activated at the robot interface, if the
RWF unit is used in a robot setup.

IGC (Intelligent Gas Control) (not all models)
The RWF unit is supplied with IGC, a function for
2
dynamic flow rate adjustment according to welding job.
Set the gas flow at 2-6 bar.
Calibrate the IGC flow at the welding machine or
remote control unit (see user guide for detailed descrip-
tion).
Gas test
The gas flow test function can be activated at the robot
interface or by pressing the gas test key on either weld-
ing machine or remote control unit (see user guide for
detailed description).
Status indicator (7)
• LED off: RWF is not active. Use robot interface or
2
connected torch to activate the RWF
• Flashing LED: RWF is active but not CAN-connected
2
to the power source. Check the CAN-mains cable and
mains plug.
• LED on: RWF is active.

AIR Clean (1+2) (not all models)
If the RWF unit is used along with the RCI
2
interface, it is possible to connect a compressor unit for
cleaning the gas nozzle. Set the compressed air at max.
8 bar and use the robot interface for control.
Collision protection for robot controller (10)
The collision protection function enables connection of a
mechanical fuse to the robot torch.
This prevents the torch from getting out of calibration
in case of collision with a workpiece. The function is
only applicable if the RWF
interface setup.

TOUCH Sensing (11)
For welded seam localization; this function is applicable if the
RWF unit is used in an RCI
2
welding wire or a contact tip to create electrical contact. The
robot automatically adjusts the welded seam position prior to
arc ignition.
For exact positioning of the welding torch, it is possible to use
the Touch Sensing signal. This option is available when using
Fieldbus communication only.
When the welding wire has contact to the work piece, the
robot/controller is told so by changing the status of an output
bit. Touch sensing can also be connected to the gas nozzle.
N.B. Gas nozzle sensing is automatically enabled through a
relay when activating touch sensing. The relay will, for
safety reasons, disconnect the gas nozzle sense signal
during welding.
Activate Touch sensing by enabling the Touch sensing input bit.
E.x. For Sigma Next this is input Bit # 123. See Fieldbus
configuration file for more details.
Read the Touch sensing status output bit.
When the welding wire (or optional the gas nozzle) has contact
to work piece, while not welding:
E.x. For Sigma Next output Bit # 147 is ON when there is
contact, and OFF when no contact.
See Fieldbus configuration file for more details.
