IMPORTANT To facilitate the exact positioning of the wire electrode, the following se-
quences are possible when the "Feeder inching" button is pressed and held down.
- 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 you release the "Feeder inching" 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 "Feeder inching"/"Gas test" button, the torch trigger can be used in the same
way. Before using the torch trigger for wire threading, proceed as follows:
Press the "Mode" button to select 2-step mode
CAUTION! Risk of injury from springiness of spooled wire electrode. When insert-
ing the wire electrode into the 4-roller drive, hold the end of the wire electrode
firmly to avoid injuries caused by the wire springing back.
CAUTION! Risk of damage to the welding torch from sharp end of wire electrode.
Deburr the end of the wire electrode well before feeding in.
