Migatronic RWF 30 Betriebsanleitung Seite 8

Connection and operation
The RWF 30 unit is supplied ready for use with
SIGMA SELECT in both standard and robotic setups.
It is possible to connect up to three RWF 30 units to a
welding machine/power source.
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 30 unit is used in a robot setup.
IGC (Intelligent Gas Control)
The RWF 30 unit is supplied with IGC, a function for
dynamic flow rate adjustment according to welding
job. Set the gas flow at 2-6 bar.
Calibrate the IGC flow at the 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
the remote control unit (see user guide for detailed
description).
Status indicator (7)
• LED off: RWF is not active. Use robot interface or
connected torch to activate the RWF unit.
• Flashing LED: RWF is active but not CAN-connected
to the power source. Check the CAN-mains cable
and mains plug.
• LED on: RWF is active.
AIR Clean (1+2)
If the RWF unit is used along with an integrated robot
interface, it is possible to connect a compressor unit
for cleaning the gas nozzle. Set the compressed air and
use the robot interface for control.
TOUCH Sensing (11)
For welded seam localization; this function is
applicable if the RWF unit is used in an integrated
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 unit is used in an
integrated robot interface setup.
For more information about TOUCH Sensing and Collision
protection, please refer to the SIGMA SELECT Robo manual
(50115056).
