7-4. Setting A Crater Fill Sequence
To turn on Crater Fill, press the CRATER
button. The CRATER ON INDICATOR will
illuminate 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 para-
meters 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 are ad-
justable.
Crater Wirefeed Speed (WFS) − Sets the
Crater Fill wirefeed speed. This setting is a
percentage of the wirefeed speed the unit is
set to for welding. Range of this setting is
from (X0.30 to X1.00). Example: If the weld
wirefeed speed is 200 and WFS is X0.50,
the Crater Wirefeed Speed is 100.
Crater Arc Length (ARC.L) − Sets the arc
length longer or shorter during the CraterFill
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).
Example: If the weld arc length is set to 50
and ARC.L is X0.50, the Crater Arc Length
is 25.
.
When the DISP 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 set to PULSED MIG, the Crater Voltage
setting will change if the wire and gas pro-
gram selection is changed.
Crater Ramp Time (RAMP) − The amount
of time it takes to transition from the weld to
the Crater wirefeed speed setting. Range of
this setting is from (0.1 to 5.0) seconds.
Crater Fill Time (TIME) − The amount of
time the wirefeed speed is active at the
Crater 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.
