tion is obtained; the gas exits from the
torch without welding wire advancing
and without generating Power Source
output current.
BM Quick-fitting valve. Compressed air in-
take for torch cleaning. Connect to the
compressed air line.
BN Hole. For welding wire intake.
BO Connector.
For connection to the power source.
Connect the connector of the service
cable of the power source - wire feeder
(SRS) extension cable.
4.3 BA connector (external signals).
NOTE: All command signals must be connected
to contacts free from voltage.
Motor +/-. Output voltage for Push-Pull torch motor
drive.
Wire Inch. Digital input, functionally parallel con-
nected to the Wire Inch signal coming
from Robot. If Wire Retract is active Wire
Inch is not operative.
GND-ISO. 0 V reference for external signals.
Start +/-. Start command input, functionally parallel
connected to the start command of the
BB central adapter and to the Arc-On
signal coming from Robot.
Wire Retract. Digital input, functionally parallel con-
nected to the Wire Retract signal coming
from Robot. If Wire Inch is active Wire
Retract is not operative.
Gas Test. Digital input, functionally parallel connect-
ed to the Gas Test signal coming from
Robot.
+5V/GND. Output voltage for eventual Push-Pull
torch motor encoder supply.
Gas nozzle. Digital input. Connect to an external
gas flow meter (optional kit).
Collision Protection +/-. Digital input. Is repeated
to the Robot Interface with 10 ms max.
delay; doesn't produce any effect on
welding process.
+12V_ISO. Output voltage for external signals supply.

5 MAINTENANCE.
Periodically make sure that the Welding System
equipment and all connections are in proper condi-
tion to ensure operator safety.
Periodically open the panels of the Wire Feeder to
check the internal parts. Periodically remove dirt or
dust from the internal parts, using a jet of low-pres-
sure dry compressed air or a brush.
Check the condition of the internal power connec-
tions and connectors on the electronic boards; if you
find "loose" connections, tighten or replace the con-
nectors.
Remove any dirt or metal dust from the wire liner
and gearmotor unit, using a jet of low-pressure dry
compressed air or a brush.
Make sure that the mechanical parts of the roller unit
are not worn to the point where they need to be re-
placed.
Check the condition of the electrical connectors and
pneumatic fittings; replace if damaged.
After making a repair, be careful to arrange the wiring
in such a way that the parts connected to the power
supply are safely insulated from the parts connected
to the welding circuit.
Do not allow wires to come into contact with moving
parts or those that heat up during operation.
Mount the clamps as on the original machine to pre-
vent, if a conductor accidentally breaks or becomes
disconnected, a connection from occurring between
Power Supply and the welding circuits.
