CAUTION!
Risk of injury from wire electrode emerging at speed.
When pressing the feeder inching button, keep the welding torch away from your face and
body, and wear suitable protective goggles.
IMPORTANT!
To facilitate the exact positioning of the wire electrode, the following sequences are
possible when the welder presses and holds the feeder inching button:
-
Hold the button for up to
one second
... the wire feed speed stays at 1 m/min
or 39.37 ipm for the first second.
-
Hold the button for up to
2.5 seconds
... after one second has elapsed, the
wire feed speed increases at a uniform
rate over the next 1.5 seconds.
-
Hold the button for
longer than 2.5 se
-
conds
... after a total of 2.5 seconds,
the wire is fed at a constant rate equal
to the wire feed speed set for the Fdi
welding parameter.
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 continuously po
-
sition the wire at a low wire feed speed of 1 m/min or 39.37 ipm where necessary.

NOTE!
Risk from excessive contact pressure.
This can result in severe damage to property and poor weld properties.
► Set the contact pressure in such a way that the wire electrode is not deformed but nev
