The LN-25™ PRO is specially engineered to be the
most rugged portable wire feeder available.
Several models of the LN-25™ PRO are offered to
best meet individual welder needs. The Extra Torque
model features additional torque gearing for reliable
feeding of large diameter FCAW wires. All of the mod-
els include a gas solenoid and flow meter for the flexi-
bility to run most wire processes.
The plastic case is molded from a high impact, flame
retardant plastic for durability and low weight. The
patent pending design keeps the internal components
protected and dry.
The heart of the LN-25™ PRO is the 2 roll MAX-
TRAC™ 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.
The LN-25™ PRO has only two p.c. boards that are
designed to be simple, reliable and easy to service.
