Method 2
Retracting the wire electrode in 1 mm increments (0.039 in. increments) – always
press the wire retract button for less than one second (tap)
IMPORTANT! Do not allow long lengths of wire electrode to be retracted, as the
wire electrode is not wound onto the wirespool when retracted.
IMPORTANT! If there was a ground earth connection with the contact tip before
the wire retract button was pressed, the wire electrode will be retracted when the
button is pressed until it is short-circuit-free - it retracts by no more than 10 mm
(0.39 in.) with each press of the button.
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 accompanying
flow of gas or current
- While the button is pressed, the wirefeeder runs at the preset feeder inching
speed
Wire threading can be performed using one of two methods:
Method 1
Threading the wire electrode using the preset feeder inching speed:
- Press and hold the wire threading button
After pressing the wire threading button, the wire electrode is thread in by 1 mm
(0.039 in.).
After a short pause, the wirefeeder continues to feed in the wire electrode - if the
wire threading button remains pressed, the speed increases every second by 10
m/min (393.70 ipm) up to the preset feeder inching speed.
If the wire electrode comes into contact with a ground earth connection, the wire-
feeding will be stopped and the wire electrode will be retracted again by 1 mm
(0.039 in.).
Method 2
Threading the wire electrode in 1 mm increments (0.039 in. increments) - always
press (tap) the wire threading button for less than 1 second
If the wire electrode comes into contact with a ground earth connection, the wire-
feeding will be stopped and the wire electrode will be retracted again by 1 mm
(0.039 in.).
NOTE!
If there is a ground earth connection with the contact tip before the wire threading
button is pressed, the wire electrode will be retracted when the button is pressed un-
til it is short-circuit-free – it retracts 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.) of wire
retraction, pressing the wire threading button again will cause the wire electrode to be re-
tracted 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.
