6.1.1 WireFeedSpeed
This 16-bit function controls the wire feed speed for
welding in scaled or non-scaled mode, depending on the
user setup.
In non-scaled mode:
• The minimum setup value is 5 (0.5 m/min).
• The maximum setup value is 250 (25.0 m/min).
• The minimum step is 1 (0.1 m/min) between 0.5
and 5.0 m/min.
• The minimum step is 5 (0.5 m/min) between 5.5
and 25.0 m/min. Other step values are rounded
up to the nearest multiple of 0.5 m/min.
In scaled mode:
• The minimum setup value is 0 (0.0 m/min).
With this value, the welding system limits the
minimum speed to 0.5 m/min.
• The maximum setup 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 value
is calculated from the setup value by means of
the value scaling formula.
This value has an eect only when the OnlineControl
signal is set (1), and it overrides the corresponding memory
channel value. If the OnlineControl signal is cleared (0), the
wire feed speed from the active memory channel is used.
6.1.2 Voltage
This 16-bit function controls the welding voltage for the
MIG process. For other processes, the FineTuning function
is used instead. The value is given in scaled or non-scaled
mode, depending on the user setup.
In non-scaled mode:
• The minimum setup value is 80 (8.0 V).
• The maximum setup value is 460 (46.0 V).
• The minimum step is 1 (0.1 V).
In scaled mode:
• The minimum setup value is 0 (0.0 V). With this
value, the welding system limits the minimum
voltage to 8.0 V.
• The maximum setup value is the voltage scaling
value, which is interpreted as 46.0 m/min.
• The minimum step is 1. The voltage is calculated
from the setup value by means of the value
scaling formula.
The value has an eect only when the OnlineControl
signal is set (1), and it overrides the corresponding memory
channel value. If the OnlineControl signal is cleared (0), the
value from the active memory channel is used.
