NOTE!
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 10 mm (0.39 in.) with each press
of the button.
If the wire electrode still needs to be retracted, press the wire retract button again.
(4) Wire threading button
For threading 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
Retracting the wire electrode using the preset feeder inching speed:
Press and hold "Wire threading" button
- The wire electrode will be threaded 1 mm (0.039 in.) after the wire threading but-
ton 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 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 the wire threading button for less than one second (tap)
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 was a ground earth connection with the contact tip before the wire threading
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 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.
