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.

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.
