GENERAL DESCRIPTION
General Physical Description
The LN-25™ PRO DUAL POWER is specially engineered to
be the most rugged portable wire feeder available.
The LN-25 PRO 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 dis-
connect the work sense clip and connect the control cable.
The dual power feeder is a universal feeder great for both
field and shop service.
The plastic case is molded from a high impact, flame retar-
dant plastic for durability and low weight.
The heart of the LN-25™ PRO DUAL POWER 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 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 LN-25™ PRO DUAL POWER have adjustable WFS
range for improving the knob sensitivity. 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 LN-25™ PRO
DUAL POWER .
• The digital displays do not show preset voltage
• Not compatible with K489-7 Euro connector (except
K2614-8)
