OPT/i WF gas test
& wire threading
No. Function
(1) OPT/i WF gas test & wire thread-
ing
(2) Operating status LED
lights green when the device is
ready for use
(3) Gas-test button
for setting the required gas flow rate
on the pressure regulator
- Gas will flow out for 30 s after
pressing the gas-test button.
Press the button again to stop
the gas test flow before the end
of this period
No. Function
(4) Wire retract button
retraction of wire electrode without accompanying flow of gas or current
The wire electrode can be retracted using one of two methods:
Variant 1
retracting the wire electrode using the preset wire retract speed:
- Press and hold the wire retract button
- The wire electrode will be retracted 1 mm (0.039 in.) after the wire retract
button is pressed
- After a short pause, the wire-feed unit continues to retract the wire elec-
trode. If the wire retract button remains pressed, the speed will increase
every second at a rate of 10 m/min (393.70 ipm) until the preset wire
retract speed is reached.
Variant 2
retracting the wire electrode in 1 mm stages (0.039 in. stages) - always press
the wire retract button for less than one second (tap)
NOTE!
Do not allow long lengths of wire electrode to be retracted, as the wire electrode is
not wound onto the wirespool when retracted.
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 than 10 mm (0.
39 in.) with each press of the button.
If the wire electrode still needs to be retracted further, press the wire retract button again.
