Wire-threading button
There are two options available for the wire threading:
Option 1
Thread the wire electrode at the preset feeder inching speed:
- Press and hold the wire-threading button
- After pressing the wire-threading button, the wire electrode will be threaded in by
1 mm (0.039 in.)
- After a brief pause, the wirefeeder continues threading in the wire electrode – if the
wire-threading button is kept pressed down, then the speed increases with each fur -
ther second by 10 m/min (393.70 ipm) until the preset feeder inching speed is reached
- If the wire electrode meets a ground earth connection, then the wirefeeding is stopped
and the wire electrode is retracted again by 1 mm (0.039 in.)
Option 2
Thread the wire electrode in 1 mm steps (0.039 in. steps)
- Always press (touch) the wire-threading button for less than 1 second
- If the wire electrode meets a ground earth connection, then the wirefeeding is stopped
and the wire electrode is 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 is retracted by pressing the wire threading but -
ton 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 after the 10 mm (0.39 in.) wire retraction there is still a ground earth connection with the
contact tip, then when the wire-threading button is pressed again, the wire electrode is re -
tracted again by a maximum of 10 mm (0.39 in.). The process is repeated until there is no
longer any ground earth connection with the contact tip.
