SAFETY PRECAUTIONS
READ AND UNDERSTAND ENTIRE SECTION
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 from breathing zone.
WELDING SPARKS can cause fire or explosion.
• Keep flammable material away.
ARC RAYS can burn.
• Wear eye, ear and body protec- tion.
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.
