GENERAL DESCRIPTION

General Physical Description
The RED-D-ARC LN25™ PRO EXTREME is special-
ly engineered to be the most rugged portable wire
feeder available.
(For Code 12167 only) a dedicated gun adapter is
mechanically secured into the feed plate but directly bolted
to the feederʼs internal electrical welding buss bar to reduce
the likelihood of overheating occurring at the feed plate. The
bushing accepts Magnum Pro guns (Tweco #2 to #4).
Models include a gas solenoid for the flexibility to run
most wire processes.
The plastic case is molded from a high impact, flame
retardant plastic for durability and low weight.
The heart of the RED-D-ARC LN25™ PRO
EXTREME is the 2 roll MAXTRAC™ drive. The
patented features on the wire drive offer tool-less
changing of the drive rolls and wire guides for quick
spool changes. A tachometer controlled motor pow-
ers the patented drive rolls for smooth, steady feeding
without slippage.
With a 450 amp, 60% duty cycle rating, these feeders
are ready for heavy duty welding.
OPERATION
General Functional Description
The RED-D-ARC LN25™ PRO EXTREME has
adjustable WFS range for improving the knob sensitiv-
ity. The low range is great for critical welds with
Innershield wires, and the upper range is suitable for
general purpose welding. Selection of the WFS range
is by a rocker switch or through the set-up menu on
meters with digital displays.
RECOMMENDED PROCESSES
• GMAW
• FCAW
PROCESS LIMITATIONS
• GMAW-P procedures must be qualified by the cus-
tomer.
• Across-the-Arc models are not recommended for
stitch or spot welding.
EQUIPMENT LIMITATIONS
• The duty cycle of the wire feeder is 450A, 60%.
Duty cycle is based upon the amount of welding per-
formed in a 10 minute period.
• The maximum spool size is 45 lb. (24 Kg), 12"
(305mm) diameter.
• Maximum FCAW gun length is 15 ft.
• Maximum GMAW gun length is 25 ft.
• K2330-1 Timer Kits do not work with the feeder. Use
K2330-2 kits.
• Push-pull guns do not work with the RED-D-ARC
LN25™ PRO EXTREME .
• The digital displays do not show preset voltage
• Not compatible with K489-7 Euro connector (except
K2614-7,-8)
