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 upon power up. Three
welding sequence LEDs are located above
the Sequence push button: Start, Crater,
and Preflow/Postflow. The applicable LED
illuminates to indicate the active welding se-
quence.
Welding sequences other than weld must
be set prior to initiating the arc. When the
unit enters a welding state, all sequence dis-
play modes are terminated and the weld dis-
play 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 shown in the dis-
plays.
•
When the Sequence push button pressed a
second time, the Crater sequence LED
flashes; the Sequence LED also remains
flashing. In this condition, the unit is in the
Crater sequence display mode, and the
Crater sequence parameters are shown in
the displays.
•
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 dis-
play mode, the upper display shows the pre-
flow time, and PRE is shown in the lower
display. To change the preflow time, press
the upper display and turn the Adjust con-
trol.
To select between preflow (PRE) and post-
flow (POST), press the lower display button
and turn the Adjust control. When POST is
selected, the upper display is used to speci-
fy postflow time.
•
When the Sequence button is pressed a
fourth time, the unit returns to the Welding
sequence display mode.

Pressing the Flux push button
toggles the flux valve control open
and closed. When the Flux push
button LED is lit, the flux valve con-
trol is open.
When the flux valve control is set to
“AUTO” (see Section 6-6), the flux
valve opens when the Start button
is pressed, and closes when the
last sequence is finished.
