GENERAL DESCRIPTION
The LN-15 is a light weight, portable, durable semi-
automatic wire feeder.
The LN-15 accommodates spools 8" (200mm) diame-
ter up to 4" (100mm) wide.
The domestic feeders comes factory equipped with a
K1500-2 Magnum Tweco-compatible style #2-#4 gun
bushing. Other K1500 series gun bushings are avail-
able as field installed options. European models are
factory equipped with a Fast-Mate adapter.
The wire drive is capable of operating in either a "CV"
or "CC" mode. A constant voltage (CV) power source
is recommended for flux-cored arc welding (FCAW)
and gas metal arc welding (GMAW) to obtain code
quality results. However, the LN-15 may also be used
with a constant current (CC) power source to obtain
passable results for non-critical quality applications.
The "dual procedure" mode drops the WFS to 83% of
the original set point. The voltage setting remains the
same.
• Burn-back is adjustable from 0.0 to 0.25 seconds,
with a default of 0.00 seconds.
• The preflow time is adjustable from 0.00 to 25.0 sec-
onds, with a default of 0.00 seconds.
• The postflow time is adjustable from 0.0 to 25.0 sec-
onds, with a default setting of 0.0 seconds.
The Control Cable Model features remote voltage
control with a potentiometer on the front of the feeder.
The operation of the voltage control is similar to other
feeders having "remote control" kits, such as the LN-
25. While welding, the voltage may be adjusted as
desired. The voltage setting is not a "preset" value.
Electrode output is energized in response to the gun
trigger by signals sent to the power source via the
control cable.

LN-15 CONTROL CABLE MODEL (CE)
DUTY CYCLE
The LN-15 wire feeders are intended for semi-auto-
matic use. The maximum rating of the LN-15 is based
upon a 60% duty cycle; 6 minutes of welding followed
by 4 minutes of idling within a 10 minute period.
RECOMMENDED PROCESSES
The LN-15 wire drive feeds electrode for various
processes as defined below in Table B.1.
The Control Cable Model is suitable for GMAW,
GMAW-Pulse, GMAW-STT and FCAW semi-auto-
matic applications within the rated duty cycle.
PROCESS LIMITATIONS
• The control cable model is not recommended for
SAW, SMAW, GTAW or CAG.
• The control cable model works only with power
sources having remote control output.
EQUIPMENT LIMITATIONS
Codes 11033 and higher
• The LN-15 cannot be used with the K1500-4 gun
adapter bushing.
