INTEGRATION GUIDE
3.4 Wire feeder
Use a mounting bracket to mount the wire feeder securely
on the robot arm. See the illustrated instructions included
in the product delivery package.
The wire feeder connections are described in the Sub-
section 3.6, “Interconnection cable set”.
Filler wire
Connect the wire liner to the ller wire inlet on the
rear of the wire feeder. Connect the other end of the
wire liner to the wire drum or spool and run the wire
up to the wire feeder either manually or by using wire
inch functionality at the wire drum.
Peripheral connector
For a collision sensor and the touch sensor, the wire feeder
has a common 7-pin peripheral connector at the front of
the wire feeder. The connections of the peripherals are
described later in this document.
