CAUTION!
Risk of injury from emerging wire electrode.
▶
When pressing the wire threading button or the torch trigger, keep the weld-
ing torch away from your face and body, and wear suitable protective
goggles.
IMPORTANT! To facilitate the exact positioning of the wire electrode, the follow-
ing sequences are possible when the wire threading button is pressed and held
down.

(m/min, ipm)
-
Hold the button for up to one
second ... the wire 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 speed increases
at a uniform rate over the next 1.5
seconds.
-
Hold the button for more than 2.5
seconds ... after 2.5 seconds, the
wire is fed at a constant rate equal
to the wire speed set for the Fdi
welding parameter.
If the "Wire threading" button is released and pressed again before one second
has elapsed, the sequence starts again from the beginning. This makes it possible
to continuously position the wire at a low wire speed of 1 m/min or 39.37 ipm
where necessary.
If there is no "Wire threading" button, the torch trigger can be used in the same
way. Before using the torch trigger for wire threading, proceed as follows:
1
Press the "Mode" button to select 2-step mode
2
Set the "Ito" parameter to "Off" in the Setup menu
CAUTION!
Risk of injury and damage from electric shock and from the wire electrode
emerging from the torch.
When pressing the torch trigger:
▶
Keep the welding torch away from your face and body
▶
Wear suitable protective goggles
▶
Do not point the welding torch at people
▶
Make sure that the wire electrode does not touch any conductive or earthed
parts (e.g. housing)
IMPORTANT! If the torch trigger is pressed instead of the "Wire threading" but-
ton, the welding wire runs at the feeder creep speed (depending on the welding
program) for the first 3 seconds. After these 3 seconds, wirefeeding is briefly in-
terrupted.
The welding system detects that the welding process should not start, but that
the wire is to be fed in. At the same time, the gas solenoid valve closes, and the
welding voltage on the wire electrode is switched off.
