USER INTERFACE CONTROLS
SETTING OSCILLATION SPEED
(See Figure B-2)
Oscillation Speed is the speed in inches per minute
that the Spreadarc carriage will travel back and forth.
To adjust the Oscillation Speed, press the Select
Toggle Switch up or down until the LED for Oscillation
Speed illuminates. The Display will show the current
value in inches per minute. To change the Oscillation
Speed value, press the Adjust Toggle Switch up or
down to raise or lower the Oscillation Speed value.
When the Start Button is pressed, the Spreadarc will
travel at this speed. The Oscillation speed can be
changed before active oscillation or while actively
oscillating.

SETTING FRONT DWELL TIME
(See Figure B-3)
Front Dwell is the amount of time in seconds that
oscillation will stop at the RIGHT proximity switch
(when facing the Spreadarc Control Box) while weld-
ing continues. This feature is used for good wash-in
of the weld metal with the wall of the work. To adjust
the Front Dwell time, press the Select Toggle Switch
up or down until the LED for Front Dwell illuminates.
The Display will show the current value in seconds.
To change the Front Dwell time value, press the
Adjust Toggle Switch up or down to raise or lower the
Front Dwell time value. When the Start Button is
pressed, the Spreadarc will "dwell" for this amount of
time when the proximity sensor is activated. The
Front Dwell can be changed before active oscillation
or while actively oscillating.

SETTING REAR DWELL TIME
(See Figure B-4)
Rear Dwell is the amount of time in seconds that oscil-
lation will stop at the LEFT proximity switch (when fac-
ing the Spreadarc Control Box) while welding contin-
ues. To adjust the Rear Dwell time, press the Select
Toggle Switch up or down until the LED for Rear
Dwell illuminates. The Display will show the current
value in seconds. To change the Rear Dwell time
value, press the Adjust Toggle Switch up or down to
raise or lower the Rear Dwell time value. When the
Start Button is pressed, the Spreadarc will "dwell" for
this amount of time when the proximity sensor is acti-
vated. The Rear Dwell can be changed before active
oscillation or while actively oscillating.
FIGURE B-4
JOG MODE
(See Figure B-5)
Jog is used while not actively oscillating in order to
move the carriage into a starting position. This fea-
ture is good for verifying what the Spreadarc will do
once oscillation is activated. To activate Jog, press
the Select Toggle Switch up or down until the LED for
Jog illuminates. The Display will show the current
value in inches per minute. To change the Jog speed
value, press the Adjust Toggle Switch up or down to
raise or lower the Jog speed value. The Jog feature
cannot be accessed during active oscillation.

POWER -DOWN, POWER-UP SEQUENCE
At power-down, the Spreadarc will save all parame-

At power-up, the Spreadarc will return all parameters
and settings that were stored at last power-down.
