BEFORE OPERATING MACHINE
WARNING
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.
FUMES AND GASSES can be
dangerous.
• Keep your head out of fumes.
• Use ventilation or exhaust to
remove fumes trom breathing
zone.
WELDING SPARKS can cause
fire or explosion.

tection.
LN-25

OPERATION

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
K443-1 Contactor, the LN-25 will handle up to 300
Amp 60% duty cycle.
