Passage over time of the wire feed speed when the
feeder inching button is pressed and held down
If the Feeder inching button is released and pressed again before one second has elapsed,
the sequence starts again from the beginning. This makes it possible to position the wire
continuously at the low wire feed speed of 1 m/min or 39.37 ipm when necessary.

NOTE! If Fdc is set to AUT, the value from the welding program database will be
used. If Fdc values are set manually and these values are faster than the wire
feed speed that was set for the welding operation then the feeder creep speed is
equal to the wire feed speed set for the welding operation.

mains at
1 m/min or 39.37 ipm for the first se-
cond.
- Hold the button for up to 2.5 seconds
... After one second, the wire feed
speed increases at a uniform rate over
the next 1.5 seconds.
- Hold the button for longer than 2.5 se-
t (s)
conds ... After a total of 2.5 seconds,
the wire is fed at a constant rate equal
