GENERAL DESCRIPTION
General Physical Description
The RED-D-ARC LN25™ PRO EXTREME DUAL POWER
is specially engineered to be the most rugged portable wire
feeder available.
The RED-D-ARC LN25™ PRO EXTREME DUAL POWER
has patented technology enabling the wire feeder to run
either across the arc or with a control cable. The change
over is automatic – simply disconnect the work sense clip
and connect the control cable. The dual power feeder is a
universal feeder great for both field and shop service.
(For Code 12164 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).
The plastic case is molded from a high impact, flame retar-
dant plastic for durability and low weight.
The heart of the RED-D-ARC LN25™ PRO EXTREME
DUAL POWER is the 2 roll MAXTRAC™ drive. The patent-
ed features on the wire drive offer tool-less changing of the
drive rolls and wire guides for quick spool changes. A
tachometer controlled motor powers the patent pending
drive rolls for smooth, steady feeding without slippage.
With a 450 amp, 60% duty cycle rating, these feeders are
ready for heavy duty welding.
General Functional Description
The RED-D-ARC LN25™ PRO EXTREME DUAL POWER
have adjustable WFS range for improving the knob sensitivi-
ty. 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 through the set-up
menu.
RECOMMENDED PROCESSES
• GMAW
• FCAW
PROCESS LIMITATIONS
• GMAW-P procedures must be qualified by the customer.
• 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 DUAL POWER .
• The digital displays do not show preset voltage
