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.

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

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.
