LN™-15 ACROSS THE ARC MODEL & (CE)

LN™-15 POWER-UP SEQUENCE

NORMAL POWER-UP DISPLAY

When power is first applied to the LN™-15, the dis-
play will momentarily show set-up information. For
example, it may show "CV" and "HI", indicating oper-
ation from a CV power source and the wire drive is
configured for the high speed gear. Because of limita-
tions in the display, "CV" will appear as "Cu".

After a brief moment, the LN™-15 will then display the
WFS and "---". No voltage is displayed until the trigger
is pressed.

PREFLOW, POSTFLOW AND BURNBACK TIMES

Preflow, Postflow and Burnback times are all
adjustable on the LN™-15. The LN™-15 is factory set
with all the times set to 0.0 seconds.

• The burnback time is adjustable from 0.00 to 0.25

seconds.

• The preflow time is adjustable from 0.0 to 25.0 sec-

onds.

• The postflow time is adjustable from 0.0 to 25.0 sec-

onds.

CHANGING PREFLOW, POSTFLOW OR BURNBACK TIMES:

1. Enter the “Press Spin” Set-Up Mode:

While the power to the LN™-15 is off, activate and
hold the GAS PURGE switch (Down Position).
Turn on power to the LN™-15, and continue to
hold the GAS PURGE switch until the LN™-15 dis-
plays "Press Spin". Release the GAS PURGE

switch. The LN™-15 is now in the "Press Spin" set-
up mode. If after 15 seconds no other action is
taken, the LN™-15 will then revert to normal oper-
ation.

2. Rotate the WFS knob until the desired timer is dis-

played.

Preflow:

Postflow:

Burnback:

3. Activate and then release the GAS PURGE switch

to select the timer. The time will then display in the
right hand side of the display. Example:

4. Rotate the WFS knob to adjust the time to the new

setting.

5. Press the GAS PURGE switch again to save the

setting. The LN™-15 will then return to the original
"Press Spin" mode in step 1.

6. To exit the "Press Spin" set-up mode, turn off power

to the LN™-15, or simply wait 15 seconds and the
LN™-15 will enter normal operation.

WELDING MODE CV/CC MODE AND WFS UNITS

The CV/CC mode and WFS units are all readily
changed during the power-up sequence. The LN™-15
is factory set for "CV" welding power sources and
"inches per minute" for the wire feed speed units.

• The CV/CC mode is selectable for either CV for

Constant Voltage power sources and CC for
Constant Current power sources. Use CV power
sources when making critical welds.

• The WFS units is selectable for either in/min and

m/min.

CHANGING THE CV/CC MODE, OR WFS UNITS:

1. Enter the “Press Spin” Set-Up Mode:

While the power to the LN™-15 is off, activate and
hold the GAS PURGE switch (Down Position). Turn
on power to the LN™-15, and continue to hold the
GAS PURGE switch until the LN™-15 displays
"Press spin". Release the GAS PURGE switch.

The LN™-15 is now in the "Press Spin" set-up
mode. If after 15 seconds no other action is taken,
the LN™-15 will then revert to normal operation.
