8-1. 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 Control (TRIG) − Sets the gun
trigger control. The trigger control can be
configured as (STD, HOLD, or SPOT).
Trigger Hold Delay (HOLD) − Additional
trigger setting only appearing in the menu
when the trigger control is set to (TRIG
HOLD). Trigger hold delay time is the min-
imum 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 trigger 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 re-
leased within 6.0 seconds for trigger hold to
become active. Once the trigger hold func-
tion is active, the wire feeder will continue
feeding wire until the trigger is pressed and
released again.
Trigger 4T − Allows the operator to select
between weld parameters and crater pa-
rameters using the gun trigger. Crater time
must be set for at least 0.2 seconds to
Notes

make this function operational. If gun trig-
ger is released during welding the unit goes
into trigger hold - pressing and holding trig-
ger again will cause the unit to stay in crater
until trigger is released and crater parame-
ter times out.
Trigger Spot Time (SPOT) − Additional
trigger setting only appearing in the menu
when the trigger control is set to (TRIG
SPOT). The SPOT time is the length of
combined time for the start (if applicable)
and the weld sequence. The weld will end
when the set time has expired or the trigger
has been released, whichever occurs first.
The spot time is reset when the trigger is re-
leased.
Remote Process Select − For MIG (MIG)
operation, the Left Display always shows
Voltage. For Pulsed MIG (PULS) opera-
tion, the Second Level Setup Menu Display
(PULS) option selects whether Voltage
(VOLT) or Arc Length (ARC.L) is shown in
the Left Display.
.
A Remote Process Select capable
power source automatically switches
to the selected weld process when this
option is changed at the wire feeder.
The wire and gas program selections
for each weld process must be set at
the power source.
.
When Trigger Schedule Select (see
Section 8-2) is enabled, the Weld Pro-
cess option can be set independently
for each schedule. This allows the op-
erator to remotely change the weld
process at the wire feeder and power
source with a single tap of the welding
gun trigger.
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 5.0) 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 10.0) seconds.
Run−In Speed (R−IN) − The wire feed
speed prior to the welding arc being struck.
This setting is a percentage of the wire feed
speed the unit is set to for welding. Range
of this setting is from (X0.10 to X0.99 to
OFF). Example: If the weld wire speed is
200 and R−IN is X0.50, the run−in wire
speed is 100.
Burnback (B.BAK) − Burnback sets a
time from 0 to 0.25 seconds in increments
of 0.01 seconds. This is the time that the
arc is allowed to stay on after the wire stops
feeding.
Burnback Volts (VLTS) − Sets the voltage
used for burnback. The range is the same
as the selected power source. Measured in
0.1 volt increments.
Retract (RTRK) − When enabled, the user
can set a distance in inches from 0 to 1.5
inches. This is the distance the wire will
backup after welding stops.
Profile Pulse ON/OFF − When Profile
Pulse is On, the pulse parameters and wire
speed are coordinated to produce a con-
sistent ripple pattern.
.
Additional PROFILE PULSE menu
items may appear in the SETUP
MENU when PROFILE PULSE is act-
ive. See Section 8-7.
