GENERAL DESCRIPTION
General Physical Description
The LN-25™ PIPE is specially engineered to be the
most rugged portable wire feeder available and meets
the individual welder needs. This model includes a
gas solenoid for flexibility 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™ PIPE
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™ PIPE has only two p.c. boards that are
designed to be simple, reliable and easy to service.
OPERATION
