The LN-15 is one of the smallest and most maneuverable wire feeders
for the construction, shipbuilding and pipeline industries. It uses a high
temperature, abrasion resistant plastic case, aluminum alloy roll cage
and fully encapsulated PC boards.
The LN-15 is available in both Across-The-Arc and Control Cable
versions. Both offer outstanding welding performance on a wide variety
of steel, stainless steel, aluminum and alloy materials.
Professional Features:
• Adjustable carrying strap makes it easy to carry and hang.
• Fully enclosed molded case is heat, spatter and impact
resistant.
• Double latch case seals tight to protect drive system and wire from
dirt, dust and rain.
• Full body aluminum roll cage provides sturdy impact protection and
all-around handles for easy portability.
Base Unit Includes:
• K1500-2 Gun Receiver Bushing.
• Carrying Strap.
• Spindle Adapter for 8" O.D. Spools.
• Standard contactor with Across-The-Arc model.
equired Options:
• agnum®Gun and Cable Assembly
• Drive Roll Kit
• Separate Control Cable -10 ft. (Control Cable odel only)
Advantage Lincoln
Performance:
• Both models are designed for IG, Pulsed IG, Flux-Cored and
etal-Cored welding processes using lightweight 8" (203 mm)
diameter spools. The Control Cable version is also designed for
the STT®(Surface Tension Transfer®) process.
• axtrac®wire drive system easily feeds .023"-.052"
(0.6 - 1.3 mm) solid and .035"-5/64" (0.9 - 2.0 mm) cored wires.
• Compact unit fits easily through 14" (356 mm) diameter
manhole/manway.
• anufactured under a quality system certified to ISO 9001
requirements.
• Three-year warranty on parts and labor.
Simple Controls:
• Bright LED digital meters are easy to read in adverse lighting
conditions.

ISO 9001 certified for quality and customer satisfaction. Designed
to IEC60974 5, CE and CSA standards. Meets IP23S environmental rating.
Strong
• Sturdy aluminum roll cage protects feeder from damage.
Durable
• Fully enclosed molded case is heat, spatter, and impact resistant.
Protected
• Fully encapsulated “potted and trayed” PC Boards protect
internal systems from heat and humidity.
Control Cable Model (K1871-1)
• Connect a Control Cable (K1819-10) and the electrode welding
cable between the power source and the feeder. Features wire
feed speed and voltage control on the front of the unit.
Across-The-Arc Model (K1870-1)
• Operates across the arc with a DC power source supplying
between 15 VDC and 110 VDC. Simply connect the voltage sense
lead to the work, then connect the LN-15 to the electrode cable.

NOTE:
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. The LN-15 may be used with a constant current (CC) power source for non-critical applications where weld quality
and deposition properties are not critical.
