Additional Features

The Lincoln LN-25 includes a voltmeter, a gas solenoid, and an internal contactor. Can be operated with all electric and engine-driven welders with CV capability but can also be used with CC welders for non-critical welds. The LN25 provides constant wire feed speed for use with CV power sources and arc-sensing wire feed speed for CC power sources and will handle weld currents up to 300 amps at 60% duty cycle. For MIG and flux-cored arc welding processes using from 10 lb to 44 lb wire spools. Specify wire size and type for correct drive roll selection.

Features

• Operates with most CV and CC DC type power sources
• CC and CV mode switch provides voltage-sensing mode for constant current power sources and constant speed mode for constant voltage power sources
• Operates off open circuit voltage and arc voltage so a control cable is not required
• Uses up to 44 lb (19.9 kg) spools or up to 30 lb (13.6 kg) Lincoln Readi-Reel Coils
• Selectable two range wire feed speed handles high speed, small diameter wires and lower speed, larger diameter all position, self-shielding wires
• Internal contactor provides "cold" electrode until gun trigger is pressed for an added margin of safety when welding must be performed under electrically hazardous conditions
• "Cold" inch switch allows wire to be loaded without being electrically "hot"
• Fixed burnback time delay prevents electrode from sticking in the weld crater when the gun trigger is released
• Includes DC voltmeter, meter polarity switch and 15 ft (4.6 m) direct work clip lead
• For use with Lincoln flux-cored guns and Magnum™ MIG guns
• Enhanced starting control allows for smooth arc starting in CV mode
• Dynamic braking system stops wire feed motor quickly to minimize wire overrun
• Electronic circuits protect wire feeder from overload
• Tool-less quick release wire drive tension system and gun cable connections for easy wire or gun changes
• Fully enclosed molded case meets UL94-VO flammability resistance and is heat, splatter and impact resistant
• Case has double latches for easy access to wire and includes an insulated gun holder
• Entire unit is compact and portable and will pass through a 16 inch (406 mm) diameter manhole
• Includes gas solenoid for MIG (GMAW) welding
• 3 year warranty on parts and labor
• Certified to ISO 9002 requirements
