INTEGRATION GUIDE
6.2.1 WeldingCurrent
This 16-bit function represents the average welding
current measured during the process. The value is in
scaled or non-scaled mode, depending on the user setup.
In non-scaled mode:
• The minimum value is 0 A.
• The maximum value is 1024 A.
• The minimum step is 1 A.
In scaled mode:
• The minimum value is 0 (0 A).
• The maximum value is the current scaling value,
which is interpreted as 1024 A.
• The minimum step is 1. The welding current is
calculated from the function value by means of
the value scaling formula.
6.2.2 WeldingVoltage
This 16-bit function represents the average welding
voltage measured during the process. The value is in
scaled or non-scaled mode, depending on the user setup.
In non-scaled mode:
• The minimum value is 80 (8.0 V).
• The maximum value is 460 (46.0 V).
• The minimum step is 1 (0.1 V).
In scaled mode:
• The minimum value depends on the scaled value
range and is interpreted as 8.0 V.
• The maximum value is the voltage scaling value,
which is interpreted as 46.0 V.
• The minimum step is 1. The welding voltage is
calculated from the function value by means of
the value scaling formula.
6.2.3 WeldingWireFeedSpeed
This 16-bit function represents the average wire feed
speed measured during the welding process. The value
is in scaled or non-scaled mode, depending on the user
setup.
In non-scaled mode:
• The minimum value is 0 (0.0 m/min).
• The maximum value is 250 (25.0 m/min).
• The minimum step is 1 (0.1 m/min).
In scaled mode:
• The minimum value is 0 (0.0 m/min).
• The maximum value is the wire feed speed
scaling value, which is interpreted as 25.0 m/min.
• The minimum step is 1. The wire feed speed is
calculated from the function value by means of
the value scaling formula.
6.2.4 MotorCurrent
This 8-bit function represents the average motor current
measured during the welding process.
• The minimum value is 0 (0.0 A).
• The maximum value is 100 (10.0 A).
• The minimum step is 1 (0.1 A).
6.2.5 GasFlowRate
This 16-bit function represents the average gas ow rate
measured during the welding process or when the gas
valve is forced to be open. This feature requires the gas
ow sensor to be congured properly and turned on from
the user setup.
• The minimum value is 0 (0.0 l/min).
• The maximum value is 500 (50.0 l/min).
• The minimum step is 1 (0.1 l/min).
6.2.6 ErrorNumber
This 8-bit function represents a non-zero error code if there
is a warning or an error active in the system. Otherwise
the value is zero. The error number is an enumeration that
represents the reason for the error. Refer to the A7 MIG
Welder operating manual for more information about
reasons for errors. See also the description for the Error
status signal. To clear this value, one must resolve the
error situation and reset the error by using the ErrorReset
control signal or from a user interface.
• The minimum value is 0 (no error).
• The maximum value is 255.
• The minimum step is 1.
