- 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
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 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 retracted 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.
