NOTE!
Risk when retracting the wire electrode.
No winding onto the wirespool.
▶
Do not allow long lengths of wire electrode to be retracted, as the wire electrode is
not wound onto the wirespool when retracted.
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 still needs to be retracted further, press the wire retract button again.
No. Function
(5) Wire threading button
to thread the wire electrode into the torch hosepack with no accompanying flow
of gas or current
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
- 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 preset
feeder inching speed is reached
- 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.)
Method 2
Threading the wire electrode in 1 mm increments (0.039 in. increments) – al-
ways 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.)
If there was a ground earth connection with the contact tip before the wire thread-
ing 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 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
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.
