CAUTION!
Risk of injury from emerging wire electrode.
► When pressing the wire threading button or the torch trigger, 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 se-
quences are possible when the wire threading button is pressed and held down.
- 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 se-
conds ... after 2.5 seconds, the wire is
fed at a constant rate equal to the wire
speed set for the Fdi welding parame-
ter.
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 continu-
ously 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. Be-
fore 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
