Sequence Parameters see Section 7-1.
• The Sequence push button allows the
selection of welding sequences. Five weld-
ing sequences are available. The default
sequence is the Weld sequence. The Weld
sequence is active on power up. Three
welding sequence LEDs are located above
the Sequence push button: Start, Crater,
and Preflow/Postflow. The applicable LED
illuminates to indicate which welding se-
quence is active.
• The LED illuminates to indicate that a weld-
ing sequence display mode other than Weld
is active. Welding sequences other than
Weld must be set prior to initiating the arc.
When the unit enters a welding state, all se-
quence display modes are terminated and
the weld display mode is activated.
If zero time is programmed for a timed se-
quence except for Weld, that sequence will
be skipped.
• In the weld sequence display mode, the Se-
quence push button LED is Off. When the
Sequence push button is pressed, the Se-
quence push button flashes and the Start
LEDs flash. In this condition, the unit is in the
Start sequence display mode, and Start se-
quence parameters are displayed (see Sec-
tion 7-1).
• When the Sequence push button is pressed
a second time, the Crater sequence LED
flashes. The Sequence push button LED re-
mains flashing. In this condition, the unit is
in the Crater sequence display mode, and
Crater sequence parameters are displayed.
• When the Sequence push button is pressed
a third time, the Preflow/Postflow sequence
LED flashes. The Sequence push button
LED remains flashing. In the Preflow display
mode the upper display shows the preflow
time and the lower display indicates the ab-
breviation PRE, to inform the operator that
preflow time is displayed. If the upper dis-
play push button is pressed, the Adjust con-
trol can be used to adjust preflow.
• If the lower display push button is pressed,
the Adjust control can be used to select be-
tween preflow (PRE) and postflow (POST).
When POST is selected, the upper display
can be used to specify postflow time.
• When the Sequence push button is pressed
a fourth time, the unit returns to the welding
sequence display mode.
