Operational Terms
The following is a list of terms and their definitions as they apply to the wire feeder:
General Terms:
MIG
CV weld process with individual settings of voltage and wire speed.
Pulsed MIG
CC weld process with factory taught data using peak and background current, pulse width and pulses
per second. Adaptive pulse control methods modulate one or more of the taught data parameters to
regulate or maintain a fixed arc length.
Trigger Hold
Trigger function allowing the operator to weld without continuously pressing the gun trigger. In Trigger
Hold mode, momentarily press the gun trigger until an arc is established, and welding will continue
until the gun trigger is momentarily pressed again.
Arc Length
Refers to physical distance between wire electrode and molten puddle. Term also used to represent
adjustments in the Pulsed MIG weld process.
Preflow
The amount of time that the shielding gas will flow after the trigger is pressed and before the welding
arc will be allowed to be active.
Postflow
The amount of time that the shielding gas will flow after the arc has been shut off.
Start
Provides voltage/arc length, wire feed speed and time values for modified arc start.
Crater
Provides voltage/arc length, wire feed speed and time values for modified arc end.

Setup Menu
To enter the SETUP MENU press and re-
lease the SETUP button. The SETUP
MENU INDICATOR and the SETUP
BUTTON INDICATOR will illuminate.
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 SETUP MENU press and re-
lease the SETUP button.
Items that can be adjusted in this menu are:
Trigger Hold Delay (HOLD) − Additional
trigger setting only appearing in the menu
when the trigger control is set to HOLD.
Trigger hold delay time is the minimum
amount of time the trigger must be held for
trigger hold to become active. There is a
built in maximum trigger hold time which
the trigger must be released within for trig-
ger hold to become active. The maximum
trigger hold time is always 4.0 seconds
after the trigger hold delay time. For
Example, if the trigger hold delay time is set
to 2.0 seconds, the trigger must be held for
at least 2.0 seconds and released within
6.0 seconds for trigger hold to become act-
ive. Once the trigger hold function is active,
the wire feeder will continue feeding wire
until the trigger is pressed and released
again.
Preflow (PRE) − The amount of time that
the shielding gas will flow after the trigger
is pressed and before the welding arc will
be allowed to be active. Range of this set-
ting is from (0.0 to 30.0) seconds.
Postflow (POST) − The amount of time
that the shielding gas will flow after the arc
has been shut off. Range of this setting is
from (0.0 to 30.0) seconds.

Setup Menu Level 2
To enter the SETUP MENU LEVEL 2 press
and hold the SETUP button. The SETUP
MENU INDICATOR and the SETUP
BUTTON INDICATOR will illuminate.
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 SETUP MENU LEVEL 2 press
and release the SETUP button.
Items that can be adjusted in this menu are:
Gun Type (GUN) − Indicates the gun type
detected. This setting is for information only
and cannot be adjusted.
Gun Calibration (G.CAL) − Calibrates the
gun motor to improve wirefeed speed ac-
curacy. A gun calibration is recommended
during installation or when changing guns.
To perform a calibration, connect the gun to
the feeder and thread the wire thru the con-
tact tip. Set the drive roll tension setting to
3-4 (see Section 5-8). Press and hold the
gun trigger. The feeder will begin feeding
wire with the power source output off. The
display will show (G.CAL HOLD) while the
calibration is active. When the calibration is
complete, wire feeding will stop and the dis-
play will show (G.CAL DONE).
If the calibration was unable to complete
successfully, a diagnostic error message
will appear (see Section 8-3).
Display (DISP) − Allows the preset weld
parameter adjustment to be set as voltage
or arc length. This setting affects only the
display appearance and will not affect oper-
ation. The (DISP) setting should be set to
match the power source display. When set
to (VOLT), the preset voltage set point will
be shown in the Left Display with the
VOLTS INDICATOR illuminated. When set
to (ARC.L), the preset arc length will be
shown in the Left Display with the ARC
LENGTH INDICATOR illuminated.
Product Version Information (INFO) −
Provides information about the firmware re-
vision levels for the Motor Control and the
User Interface PCB’s. The default value is
(INFO NONE). To read the firmware ver-
sions rotate the Right Adjust Knob until the
display reads (INFO MOTR) or (INFO
FRNT). The corresponding firmware revi-
sion level will momentarily appear following
a short delay.
