No. Function
(4) Wire threading button
to thread the wire electrode into the torch hosepack with no accompanying flow
of gas or current
There are two wire threading variants available:
Variant 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 wire-feed unit 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.).
Variant 2
threading the wire electrode in 1 mm stages (0.039 in. stages) - 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 is a ground earth connection with the contact tip before the wire
threading button is pressed, when the button is pressed the wire electrode will be
retracted 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.
