If the wire electrode is to be retracted further, the wire retract button
must be pressed again.
(4) Wire threading button
For threading the wire electrode into the torch hosepack with no accom-
panying flow of gas or current
While the button is pressed, the wirefeeder runs at the preset feeder inch-
ing speed.
Wire threading can be performed using one of two methods:
Method 1
Retracting the wire electrode using the preset feeder inching speed:
Press and hold "Wire threading" button
-
The wire electrode will be threaded 1 mm (0.039 in.) after the wire
threading button is pressed
-
After a short pause, the wirefeeder continues to thread the wire elec-
trode. If the wire threading button remains pressed, the speed will in-
crease every second at a rate of 10 m/min (393.70 ipm) until the pre-
set feeder inching speed is reached
-
If the wire electrode comes into contact with a ground earth connec-
tion, the wirefeeding will be stopped and the wire electrode will be re-
tracted again by 1 mm (0.039 in.)
Method 2
Threading the wire electrode in 1 mm increments (0.039 in. increments) –
always press the wire threading button for less than one second (tap)
If the wire electrode comes into contact with a ground earth connection,
the wirefeeding will be stopped and the wire electrode will be retracted
again by 1 mm (0.039 in.).
IMPORTANT! If there was a ground earth connection with the contact tip
before the wire threading button was pressed, the wire electrode will be
retracted when the button is pressed until it is short-circuit-free – it re-
tracts by no more than 10 mm (0.39 in.) with each press of the button.
If there is still a ground earth connection with the contact tip after 10 mm
(0.39 in.) after 10 mm (0.39 in.) of wire retraction, pressing the wire
threading button again will cause the wire electrode to be retracted again
by a maximum of 10 mm (0.39 in.). The process will be repeated until
there is no longer a ground earth connection with the contact tip.
