LN-15 POWER-UP SEQUENCE

Normal Power-Up Display

When power is first applied to the LN-15, the display
will momentarily show set-up information. For exam-
ple, it may show

"CV"

and

"HI"

, indicating operation

from a

CV

power source and the wire drive is config-

ured for the high speed gear. Because of limitations 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 2.50 sec-

onds.

• The postflow time is adjustable from 0.0 to 10.0 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 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.

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 "inch-
es 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 whenever possible for best results.

• 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.
