6-10 Auxiliary Menus (Continued)

Trigger Hold Setup

• If the Setup push button is pressed, the unit

allows trigger hold delay time to be set.

Trigger hold delay time is indicated by "HOLD"

in the lower display and the hold delay time in

the upper display. The adjust control can be

used to specify a new delay time for trigger

hold. Trigger hold delay time is the minimum

amount of time the trigger must be held for trig-

ger hold to work when the trigger is released

(the trigger hold function must be on). For ex-

ample, if a trigger hold delay time of 2.0 sec-

onds is defined, the operator must hold the

trigger for at least 2 seconds before releasing

it in order for the trigger hold function to work.

Once the trigger hold function is in effect, the

wire feeder will stay On until the trigger is

pressed and released again.

• There is an additional function built in called

"maximum trigger hold time" which is the

maximum length of time the trigger can be

held and the trigger hold function still work

when the trigger is released (the trigger hold

function must be on). The maximum trigger

hold time is set at 4.0 seconds after the trig-

ger hold delay time. For example, if a trigger

hold delay time of 2.0 seconds is defined,

and the operator held the trigger in for more

than 6.0 seconds, the trigger hold function

would not be in effect and the wire feeder

would stop when the trigger is released.

• When the Setup push button is pressed

again, the menu repeats to the first menu

selection of run-in wire speed selection.

Range Locks

Range locks are indicated by "LOCK" in the

upper display for wire speed or "LOCK" in the

lower display for voltage range. In a MIG pro-

gram, the voltage range lock ranges from 0 to

10 volts. In a pulse program, the trim range

lock ranges from 0 to 100. The wire feed

speed range lock ranges from 0 to 250 ipm.

Locks are program dependent and wire speed

is independent from voltage or trim.

Trigger Program Select

• If the Setup push button is pressed, the unit

allows Trigger Program Select or Trigger

Dual Schedule to be enabled or disabled.

The upper display shows "TSEL". Lower dis-

play shows "OFF" or "PROG" or "DUAL". The

Adjust Control is used to select "OFF" or

"PROG" or "DUAL".

Trigger Program Select (PROG) allows the

OM-1500-9 Page 24

operator to select programs during preflow by

clicking the trigger (pulling and releasing the

trigger in a maximum of 0.2 seconds). The

feeder will switch between any programs that

have a minimum of 0.2 seconds of preflow

time set in the weld sequence. Any combina-

tion of programs may be used. Trigger Pro-

gram Select cannot be used while welding or

with Dual Schedule.

(Example: If programs 1 and 3 have a mini-

mum of 0.2 seconds of preflow time, clicking

the trigger will toggle between programs 1 and

3).

Trigger Dual Schedule Select (DUAL) allows

the operator to switch between paired sched-

ules (programs 1−2, 3−4, 5−6, or 7−8) with the

gun trigger, but only while welding. This fea-

ture cannot be used with Trigger Hold or Dual

Schedule. To end the weld, the trigger must be

released for 0.4 seconds.

(Example: when welding with this feature en-

abled in program 1, if you release, re-trigger,

and hold again within <0.4 seconds, the active

program will switch to program 2. If the pre-

vious sequence is repeated the active pro-

gram will switch back to program 1. This cycle

can be repeated for the entire weld).

Process Select

Process selection indicated by "PROS" in the

upper display is set to either "VOLT" or "TRIM"

in the lower display. Each program can be se-

lected be be a MIG program indicated by

"VOLT" or a pulsing program indicated by

"TRIM".

Wire Feed Speed Units

Wire feed speed setting indicated by "WFS" in

the upper display is set to "IPM" inches−per−

minute or "MPM" meters−per−minute. This

setting is independent of the program se-

lected.

OPT1

• If the Setup push button is pressed, the unit

allows OPT1 to be disabled or enabled.

The upper display shows "OPT1". Lower dis-

play shows "On" or "Off". The Adjust Control

is used to select either "On" or "Off".

"OPT1" is used by the Water Flow Shutdown

Option to stop the weld sequence if water flow

to a water cooled gun is interrupted. A closed

set of contacts between pins 1 and 2 of RC26

on Interface Board (PC20) will allow feeder to

operate normally. Opening the contacts will

stop the weld sequence and display "ERR" in

the upper display and "OPT1" in the lower dis-

play.

OPT2

• If the Setup push button is pressed, the unit

allows OPT2 to be disabled or enabled.

The upper display shows "OPT2". Lower dis-

play shows "On" or "Off". The Adjust Control

is used to select either "On" or "Off".

"OPT2" is a second input that may be used

with an external device, such as a gas flow

switch, to end the weld sequence. The gas

flow switch may be used to stop the weld se-

quence if shielding gas flow to the gun is inter-

rupted. A closed set of contacts between pins

1 and 2 of RC24 on Interface Board (PC20)

will allow feeder to operate normally. Opening

the contacts will stop the weld sequence and

display "ERR" in the upper display and

"OPT2" in the lower display.

Display Hold

Display hold indicated by "DISP" in the upper

display is set to "OFF" or "HOLD" in the lower

display. When "HOLD" is selected, the unit will

hold the last weld information for 5 seconds

following weld termination. If any front panel

push button is pressed, or if the Adjust control

is activated, the display hold feature is termi-

nated.

Software Revision Level

• If the Setup push button is pressed, the unit

displays the software version being used by

the interface PCB (PC20).

• When the Setup button is pressed again, the

menu repeats.

Code

Upon leaving the auxiliary menu, the user is

asked if a password code indicated by

"CODE" in the top display should be activated.

By default the code is off, indicated by "OFF"

in the lower display. The user may enter a nu-

merical password between 0 and 999 by turn-

ing the Adjust control. When the user re−en-

ters the auxiliary menu, the password code

must be selected to gain access to the auxilia-

ry menu. A failed attempt return the user to the

weld screen and a counter is incremented. A

counter in the program display shows the

number of incorrect attempts. The user has

five attempts to enter the correct password

code before being locked out of the auxiliary

menu, indicated by "LOCK" in the lower dis-

play . The power may be cycled to continue

welding but the user will remained locked out

of the auxiliary menu.
