Setting A Crater Fill Sequence In Synergic Pulse
To turn on Crater Fill, press the CRATER
button. The CRATER ON INDICATOR will il-
luminate indicating Crater Fill is active.
To turn off Crater Fill, press the CRATER
button. The CRATER ON INDICATOR will
turn off indicating Crater Fill is inactive.
�
The factory default mode for Crater Fill
is (AUTO). The (AUTO) setting has
preset parameters. Crater Fill can also
be set to (MAN) for manual settings.
The Crater mode setting can be
changed in the CRATER MENU.
�
The Crater Tack Time (TACK) is ad-
justable in both AUTO and MAN
modes.
To enter the CRATER MENU press and hold
the CRATER button until the CRATER
MENU INDICATOR illuminates.
Rotate the LEFT ADJUST Knob to select
different menu items shown in the LEFT
DISPLAY. Rotate the RIGHT ADJUST Knob
to change menu item values shown in the
RIGHT DISPLAY.
To exit the CRATER MENU press and re-
lease the CRATER button.
Items that can be adjusted in this menu are:
Crater Mode (CRTR) - Sets the Crater
mode to (AUTO or MAN). When the Crater
mode is set to (AUTO), factory default pa-
rameters are used. The (AUTO) parameter
values appear in the menu but are not ad-
justable. When the Crater mode is set to
(MAN),
each
of
the
parameters
adjustable.
Crater Wire Feed Speed (WFS) - Sets the
Crater Fill wire feed speed. This setting is a
percentage of the wire feed speed the unit is
set to for welding. Range of this setting is
from (X0.30 to X1.00). Example: If the weld
wire feed speed is 200 and WFS is X0.50,
the Crater Wire Feed Speed is 100.
Crater Arc Length (ARC. L) - Sets the arc
length longer or shorter during the Crater Fill
Time. This setting is a percentage of the arc
length the unit is set to for welding. Range of
this setting is from (X0.50 to X1.50). Exam-
ple: If the weld arc length is set to 50 and
ARC.L is X0.50, the Crater Arc Length is 25.
�
When the PULS option in the SETUP
MENU LEVEL 2 is set to VOLT, the
Crater Arc Length setting will be re-
placed by the Crater Voltage (VOLT)
setting.
Crater Voltage (VOLT) - Sets the voltage
during the Crater Fill time. Range of this set-
ting is dependent on the power source in the
MIG process, and varies with the selected
wire and gas program in the PULSED MIG
process. If the power source weld process is
are
set to PULSED MIG, the Crater Voltage set-
ting will change if the wire and gas program
selection is changed.
Crater Ramp Time (RAMP) - The amount
of time it takes to transition from the weld to
the Crater wire feed speed setting. Range of
this setting is from (0.1 to 5.0) seconds.
OM-273244 Page 25
Crater Fill Time (TIME) - The amount of
time the wire feed speed is active at the Cra-
ter setting. Range of this setting is from (0.1
to 5.0) seconds.
Crater Tack Time (TACK) - This setting is
for tack welding without crater fill. The Crater
fill will not be active if the arc time is less
than the set time. Range of this setting is
from (0.1 to 5.0) seconds.
