9.3 Function Outlines
9.3.1 Wire Inching Function
Wire Inching
Wire Feeding
The wire is fed only while [FEED] is pressed.
Wire Retracting
The wire is retracted only while [RETRACT] is pressed.
When [FEED] or [RETARACT] is pressed simultaneously with [HIGH SPEED], the wire inching is
performed in the high speed mode.
[HIGH SPEED] + [FEED]
[HIGH SPEED] + [RETRACT]
9.3.2 Gas Flow Control Function
Gas Flow Control
The Gas Flow Control function is used to adjust the flow amount of shielding gas by opening or closing
the solenoid valve. The solenoid valve can be opened or closed by pressing [INTERLOCK] + [5/GAS
ARCOFF].
This function simply opens or closes the solenoid valve for shielding gas. Therefore, the operation
does not cause any changes in the job contents.
The Gas Flow Control function is enabled in the teach mode only.
One signal from user available signals and user outputs [#11283 (for arc 1), #11273 (for arc 2), #11263
(for arc 3), and #11253 (for arc 4)] turns ON while the [INTERLOCK] + [5/GAS ARCOFF] keys are
pressed simultaneously.
The term wire inching refers to gradually feeding or retracting the welding wire
through the torch. [FEED] and [RETRACT] are used to perform wire inching. The
wire inching simply feeds or retracts the wire, it has nothing to do with the job
procedure being taught. The wire inching is performed only in the teach mode when
the arc does not occur.
Wire retraction, high-speed inching, or high-speed retraction cannot be performed
depending on the Power Source.
The I/O of the welding power source and the above user outputs need to be assigned by
concurrent I/O. For details on I/O assignment, refer to “NX100 Concurrent I/O”.
