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 dr ive, 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 dr ive 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) (for mer ly var iable 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,-2, or-3 (depending on code number)
Contactor, the LN-25™ will handle up to 300 Amp
60% duty cycle.
