ELECTRIC SHOCK can kill.
• Do not touch electrically live
part or electrode with skin or
wet clothing.
• Insulate yourself from work
and ground.
• Always wear dry insulating
gloves.
ARC RAYS can burn.
• Wear eye, ear and body pro-
tection.
FUMES AND GASSES can be
dangerous.
• Keep your head out of fumes.
• Use enough ventilation or
exhaust at the arc, or both, to
remove fumes from your
breathing zone and general
area.
WELDING SPARKS can cause
fire or explosion.
• Keep flammable material
away.
• Do not weld on containers
which have held flammable
material.
OPERATION
WARNING
GENERAL DESCRIPTION
The LN-25 is a lightweight portable semiautomatic
wire feeder designed for “across-the-arc” operation
without a control cable on most any DC welding power
source. Simply connect the LN-25 to the electrode
cable, clip it to Work and it is ready to weld, using up
to 30 lb. coils or spools.
The wire drive, controls and wire reel are fully
enclosed in a rugged molded plastic case providing a
compact and versatile welding package ideally suited
to “on-the-go” field welding applications in virtually any
environment.
RECOMMENDED PROCESSES
AND EQUIPMENT
When combined with the quality drive roll kits and
accessories available for use with the LN-25, a
versatile portable welding system can be provided to
meet the specific needs of Innershield, submerged arc
or gas metal arc welding applications within the wire
feed capabilities of the LN-25.
The LN-25 provides constant wire feed speed for use
with constant voltage (CV) power sources, and arc-
sensing wire feed speed for use with constant current
(CC) (formerly variable voltage) power sources. Wire
speed is presettable on a dual-range calibrated dial.
The power sources recommended for use with the LN-
25 include the DC-250, -400, -600, CV-400 and R3S
type transformer machines, and the SAM-400, -650
engine welders, as well as the SA-200, -250 or SAE-
300, -400 with CV Adapter and Pulse Power 500 with
K460-1 LN-25 Kit.
WELDING CAPABILITY
The LN-25 will handle up to 500 Amp 60% duty cycle
welding currents. However, when equipped with a
K443-2 Contactor, the LN-25 will handle up to 300
Amp 60% duty cycle.
