LN-25X™

general desCriPtion

The LN-25x™ is a rugged, portable, across-the-arc wire feeder
equipped with CrossLinc™ technology. When used with a
CrossLinc™ equipped power source, this LN-25 allows the user
to adjust the welding voltage at the wire feeder front panel without
the need for a control cable. As a result, setup and changeover
time is reduced while productivity is increased.
In addition to the advantages of CrossLinc™ technology, this wire
feeder has the following features:
• Wire drive geared for great performance with both FCAW and
GMAW wires up to 5/64" diameter.
• Plastic case molded from a high impact, flame retardant material
which is lightweight and extremely durable. The patent pending
design keeps the internal components protected in harsh envri-
onments.
• MAXTRAC™ drive system. The patented features on the
MAXTRAC™ wire drive offer tool-less changing of the drive rolls
and wire guides for quick spool changes.
• Tachometer feedback on the wire drive ensures accurate speed
control with all wire types and environmental conditions.
• Bright digital meters which display voltage, current, and wire
feed speed so that the user can accurately set and verify welding
parameters.
• Rating of 450 amps at a 60% duty cycle.
