- 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 electrode. If
the wire threading button remains pressed, the speed will increase 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) – always
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.).
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
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.
