GENERAL DESCRIPTION
The LN-15 is a light weight, portable, durable semi-
automatic wire feeder.
The Control Cable Model features voltage control with
a potentiometer on the front of the feeder. The opera-
tion 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.
The LN-15 accommodates spools 8" (200mm) diame-
ter up to 4" (100mm) wide.
The feeder comes factory equipped with a Tweco
style #2-#4 gun bushing. Other K1500 series gun
bushings are available as field installed options.
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 0.0 seconds.
• The preflow time is adjustable from 0.00 to 2.50 sec-
onds, with a default of 0.0 seconds.
• The postflow time is adjustable from 0.0 to 10.0 sec-
onds, with a default setting of 0.0 seconds.
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.
PROCESS LIMITATIONS
• The control cable model is not recommended for
SAW, SMAW, GTAW or CAG.
• The control cable model works only with power
sources that have remote output control capability.
• The LN-15 does not support 4 step trigger operation.
