Wire-return button
There are two options available for retracting the wire electrode:
Option 1
Withdraw wire electrode at the preset wire return speed:
-
-
-
Option 2
Withdraw wire electrode in 1 mm steps (0.039 in. steps)
-
NOTE!
Only retract the wire electrode a small amount at a time, to avoid the wire elec-
trode becoming entangled on the wirespool during retraction.
NOTE!
If there is a ground earth connection with the contact tip, before the wire-re-
turn button is pressed, the wire electrode is retracted by pressing the wire-re-
turn button until the wire electrode is short-circuit-free—however, this must
not exceed 10 mm (0.39 in.) each time the button is pressed.
If the wire electrode needs to be retracted further, press the wire-return button
again.

After pressing the wire-return button, the wire electrode is retracted by
1 mm (0.039 in.)
After a brief pause, the wirefeeder continues retracting the wire electrode –
if the wire-return button is kept pressed down, then the speed increases with
each further second by 10 m/min (393.70 ipm) until the preset wire-return
speed is reached
Always press (touch) the wire-return button for less than 1 second
