APEX ® 3 SERIES TIG PENDANT MANUAL
If the Sector button is pushed while welding, using a
weld process that has multiple weld sectors enabled,
the weld parameter values will transition from those in
effect when the button was pushed to those associ-
ated with the next enabled weld sector in the process.
The transition period is two seconds during which the
weld parameter values gradually transition to those of
the next sector. This is the method used to manually
transition from one weld sector to the next.
In some cases the weld sector transitions occur auto-
matically provided certain conditions are met. First, the
setup selected on the Track Setup screen must be for
an outside track ring (OD Track) and the values se-
lected for track ring diameter and pipe diameter must
precisely match those of the physical setup.
Second, the weld head must be equipped with an incli-
nometer interface. Third, a weld process with multiple
sectors enabled must be active. If the above condi-
tions are met, automatic sector transition points can be
defined on the Sector Setup screen shown in Figure
27- Sector Setup Screen. The Sector Setup Screen
is displayed by pressing the AUTO selection button on
the Process Setup screen.
On the Sector Setup screen, sector transition points
are specified in terms of degrees offset from the 12
o'clock position of a horizontally positioned pipe.
Direction of travel is important in determining the val-
ues associated with the sector transition points.
If a clockwise travel direction is specified, degree val-
ues start at the 12 o'clock position with zero degrees
and increment to 359° in a clockwise direction; the
12 o'clock position will be zero degrees, the 3 o'clock
position will be 90°, the 6 o'clock position will be 180°,
and the 9 o'clock position will be 270°.
If a counter-clockwise travel direction is specified,
degree values start at the 12 o'clock position with 0
degrees and increment to 359° in a counter-clockwise
direction; the 12 o'clock position will be 0 degrees, the
3 o'clock position will be 270°, the 6 o'clock position
will be 180°, and the 9 0'clock position will be 90°.
On the right side, the Sector Setup screen displays
a representation of a cross-section of a horizontally
positioned pipe with sector markers place on the pipe
perimeter showing the position of the sector transi-
tion point for each enabled sector in the weld process
based on the travel direction.
On the left side of the screen, the same information is
displayed numerically in a table. In the middle of the
screen at the top, the current position of the weld head
(inclinometer value) is displayed with respect to the
specified travel direction.
In the middle of the screen below the weld head posi-
tion display, the selected travel direction is displayed
by highlighting either the clockwise or counter-clock-
wise arrow. At the top left of the Sector Setup screen,
the text 'AUTO SECTOR' is shown highlighted if the
auto-sector feature is enabled or grayed out if not en-
abled. This text is also displayed at the same location
on the Process Setup screen.
On the Sector Setup Screen shown in FIGURE 27-
Sector Setup Screen it shows sector transitions for a
weld process containing four enabled sectors travelling
in a clockwise direction with the auto-sector feature
enabled and the weld head currently positioned at six
degrees.
Pressing the DIR selection button switches the travel
direction between clockwise and counter-clockwise
directions.
Pressing the RESET selection button returns all avail-
able sector transitions to default locations. Default
sector transition locations are those that would evenly
space 8 sectors around the pipe: sector 1 at zero de-
grees, sector 2 at 45°, sector 3 at 90°, sector 4 at 135°,
sector 5 at 180°, sector 6 at 225°, sector 7 at 270°,
and sector 8 at 315°.
The sector numbers used here correspond to the
sector numbers which are enabled or disabled on the
Process Setup Screen. If the four sectors that were
enabled in FIGURE 27 - Sector Setup Screen were
sectors 1, 2, 3, and 5, then after pressing the RE-
SET selection button, the sector transitions would be
displayed at the following locations: 0°, 45°, 90° and
180°. Also, the numeric values displayed in the table to
the left would be displayed in the 1st, 2nd, 3rd and 5th
rows of the table. The other rows of the table would
be blank because those sectors are disabled on the
Process Setup Screen.
Pressing the Sector button (button 14 on FIGURE 4 -
Pendant Items) turns the auto-sector feature on/off.
