2 CRTR − Crater Fill
The Millermatic 350P Aluminum is
equipped with a crater fill feature. To begin
controlling this feature the user must ac-
cess the system menu by pressing both
the setup button and the arc control button
at the same time. Once in the system
menu rotate the left adjustment knob until
"CRTR" appear on the left display. There
are two crater settings: On and Off. "On"
allows manual control of the crater set-
tings. "Off" disables the crater feature.
When crater is "On" in the system menu,
the user must manually configure the
crater settings as follows. Press the Setup

Button until the display reads "CRTR".
Crater can be enabled and disabled for
each gun type (i.e. spool gun or push-pull
gun). The right adjustment knob will en-
able or disable the crater sequence for the
active gun type. Rotate the left adjustment
knob to the next menu labeled "WFS". This
represents the wire feed speed during the
crater fill period. Rotate the right adjust-
ment knob to select the desired wire feed
speed. Rotate the left adjustment knob to
the next menu labeled "VOLT" (MIG and
Synergic MIG modes) or "ARCL" (Pulse
mode). This menu represents the welding
voltage or arc length (depending on pro-
cess) during the crater fill period. Rotate
the right knob to select the desired voltage/
arc length. Rotate the left adjustment knob

to the final menu labeled "TDLY". This
menu represents the delay time to skip the
crater fill sequence, in seconds. If the arc
time is less than the TDLY time the follow-
ing trigger pull will be normal weld output,
not a crater fill sequence. For example, if
TDLY is set for 2.0 seconds, weld opera-
tion will not go into crater if the trigger is re-
leased before 2.0 seconds has elapsed.
Pressing the setup button once more will
complete setup of the crater fill paramet-
ers.
The crater fill sequence described by the
crater fill settings will execute immediately
following the weld once the trigger has
been released (assuming the TDLY time
has been satisfied).
