Threading But -
tons
Gas-test button
After pressing the gas-test button, gas is released for 30 s. Pressing the button again will
end the process prematurely.
Wire-return button
There are two options available for retracting the wire electrode:
Option 1
Withdraw wire electrode at the preset wire return speed:
- Press and hold the wire-return button
- After pressing the wire-return button, the wire electrode is retracted by 1 mm (0.039
in.)
- After a brief pause, the wirefeeder continues retracting the wire electrode—if the wire-
return button is kept pressed down, then the speed increases with each further second
by 10 m/min (393.70 ipm) until the preset wire-return speed is reached
Option 2
Withdraw wire electrode in 1 mm steps (0.039 in. steps)
- Always press (touch) the wire-return button for less than 1 second
NOTE!
Only retract the wire electrode a small amount at a time, to avoid the wire electrode
becoming entangled on the wirespool during retraction.
NOTE!
If there is a ground earth connection with the contact tip, before the wire-return but -
ton is pressed, the wire electrode is retracted by pressing the wire-return button un -
til the wire electrode is short-circuit-free—however, this must not exceed 10 mm
(0.39 in.) each time the button is pressed.
If the wire electrode needs to be retracted further, press the wire-return button again.
