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
1.
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
2
unit is used in a robot setup.
0.6/30 m/min
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
description).
Gas test
The gas flow test function can be activated at the
robot interface or by pressing the gas test key on
either welding machine or remote control unit (see
user guide for detailed description).

AIR Clean (1+2) (not all models)
If the RWF
2
unit is used along with the RCI
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.

TOUCH Sensing (11)
For welded seam localization; this function is applicable if the
RWF
2
unit is used in an RCI
2
robot interface setup and uses
welding wire or a contact tip to create electrical contact. The
robot automatically adjusts the welded seam position prior to arc
ignition.
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
2
unit is used in an RCI
2
robot interface setup.
For more information about TOUCH Sensing and Collision
protection, please refer to the RCI
manual (50115001).
