If you release the "Wire threading" button and press it again before one second has
elapsed, the sequence starts again from the beginning. This makes it possible to continu-
ously position the wire at a low wire feed speed of 1 m/min or 39.37 ipm where necessary.
If there is no "Wire threading" / "Gas-test" button, the torch trigger can be used in the usu-
al way. Before using the torch trigger for wire threading, proceed as follows:
Press the "Mode" button to select 2-step mode
Set the "Ito" parameter to "Off" in the Setup menu
IMPORTANT! If the torch trigger is pressed instead of the "Wire threading"/"Gas-test"
button, the welding wire runs at the feeder creep speed (depending on the welding pro-
gram) for the first 3 seconds. After these 3 seconds, wirefeeding is briefly interrupted.
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.
If the torch trigger is kept pressed, wire feeding restarts immediately without shielding gas
and welding voltage, and the process continues as described above.
- 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, the wire feed
speed increases 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 feed speed set for the Fdi
welding parameter.
CAUTION! Risk of injury and damage from electric shock and from the wire elec-
trode 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 etc.)
