3.8 Interconnection cable set
The interconnection cable set contains several cables and
hoses wrapped in a strong fabric sleeve equipped with
a zipper. The cable set is used for delivering the welding
power, shielding gas, cooling liquid, and control signals
from the welding power source to the wire feeder.
The interconnection cable set is available with and without
cooling hoses.

3.8.1 The arc measurement cable
The arc measurement cable is a part of the arc voltage
measurement function, which is used to calibrate the
actual arc voltage and power regardless of the welding
cable diameter or length.
Connect the cable to the arc measurement input
connector at the rear of the power source.
Connect the cable to the arc measurement
output connector at the wire feeder.
For using the arc voltage calibration, connect a
separate earth cable (included in the package)
from the wire feeder to the work piece, near the
weld joint.
Check the route of the earth cable. Incorrect routing
can cause damage to the cable or the robot when the
robot is moving.
When the system is ready to run, calibrate the power
source by welding with 1-MIG, MIG or with Pulse MIG for
at least 5 seconds, with the arc measurement cable and
the earth cable connected. After calibration the earth
cable can be detached, although it is recommended to
use it always. The cable is required when monitoring arc
voltage.
Using the arc measurement cables affects the
functionality of the touch sensor. See the A7 MIG Welder
Operating manual for details.
If you are using a sub-feeder, enter the length of
the sub-feeder to the SubFeederLength parameter in the
setup panel. This parameter is not available in the web
user interface.
