4.10 Gas flow sensor
The welding system is equipped with a gas flow sensor that is located inside the wire feeder.
The sensor is capable of sensing gas flow for any mixture of six base gases containing
Argon (Ar), Carbon dioxide (CO₂), Nitrogen (N₂), Hydrogen (H₂), Oxygen (O₂) and Helium
(He). The gas flow sensor provides both flow indication and flow rate outputs. The outputs
can be monitored in the web user interface and in a robot pendant through the digital
robot interface.
These instructions and specifications apply to a gas flow sensor unit that is a standalone
device inside the wire feeder.
They do not apply to an integrated gas flow sensor that uses wire feeder hardware. To
check the type of the gas sensor in use, go to setup panel's
menu > Device information
and navigate through the list. The standalone gas flow sensor
device appears in the list as

4.10.1 On/Off control
The gas flow sensor can be turned on and off. By default, it is off. When turned on, flow rate
and status are monitored in web user interface's welding display.

4.10.2 Gas flow sensing level
The welding system can indicate flow rate below sensing level. This feature is enabled
when the gas flow sensor has been turned on, the gas flow sensing level has been set to
greater than zero, and gas is flowing by the means of manual control, or during welding.
The indication is reported 3 seconds after the gas valve has been opened. The status is
monitored in the welding display of the web user interface, and is passed to the robot via
the digital robot interface as the GasFlowOk signal.

4.10.3 Gas mixture setup
Knowing the exact mixture of the shielding gas is necessary for precise gas flow
measurement. The gas flow sensor unit supports flow measurement for any mixture of
the six base gases, including pure base gases. The mixtures are set up by specifying the
percentage of each gas in the mixture.
Reconfigure the mixture every time when the type of the shielding gas is changed.
The percentage of Argon is changed automatically when adjusting other gases, the
Enabled
total percentage being always 100 %. For example, if Carbon dioxide is increased from 0 to
18 %, Argon is changed automatically from 100 to 82 %. This applies for Ar+18CO₂ gas. If
Carbon dioxide is increased to 100 %, Argon is decreased to 0 %. This applies for pure CO₂
gas, etc.
