Setup Menu

To enter the SETUP MENU press and re-

lease the SETUP button. The SETUP

MENU INDICATOR and the SETUP BUT-

TON 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 release

the SETUP button.

Items that can be adjusted in this menu are:

Trigger Control (TRIG) - Sets the gun trig-

ger control. The trigger control can be con-

figured 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 mini-

mum 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 sec-

onds, the trigger must be held for at least

2.0 seconds and released within 6.0 sec-

onds for trigger hold to become active. Once

the trigger hold function 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 param-

eters using the gun trigger. Crater time must

be set for at least 0.2 seconds to make this

function operational. If gun trigger is

SECTION 8 – PROGRAMMING

released during welding the unit goes into

trigger hold - pressing and holding trigger

again will cause the unit to stay in crater until

trigger is released and crater parameter

times out.

Trigger Spot Time (SPOT) - Additional trig-

ger 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 re-

leased, whichever occurs first. The spot time

is reset when the trigger is released.

Remote Process Select - For MIG (MIG)

operation, the Left Display always shows

Voltage. For Pulsed MIG (PULS) operation,

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

Process option can be set independ-

ently for each schedule. This allows

the operator 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 setting 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 al-

lowed 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 in-

ches. This is the distance the wire will back-

up after welding stops.

Profile Pulse ON/OFF - When Profile Pulse

is On, the pulse parameters and wire speed

are coordinated to produce a consistent rip-

ple pattern.

�

Additional PROFILE PULSE menu

items may appear in the SETUP

MENU when PROFILE PULSE is ac-

tive. See Section 8-7.
