The LN-7 and LN-7 GMA are semiautomatic
constant speed wire feeders that can be used with
a variety of Lincoln engine drives, DC or CV power
sources in a shop or field environment. Both
models feature Lincoln's unique drive roll design,
which provides positive feeding, quick reloading and
durability for long life. Controlled wire feed speed
during starting provides clean, positive starts and
minimizes stubbing, skipping and spatter. For
dependable operation and precise wire feeding in a
rugged package, choose the LN-7 or LN-7
GMA.
Advantage Lincoln
• The LN-7 feeds up to 3/32" (2.4mm) solid
and 7/64" (2.8mm) flux-cored wires, from 50-500
inches per minute (1.3-12.7m/min) wire feed
speed.
• The LN-7 GMA feeds up to 1/16" (1.6mm) solid
and 5/64" (2.0mm) flux-cored wires, from 75-700
inches per minute (1.9-17.8 m/min) wire feed
speed.
• Unique drive roll design provides positive
feeding and quick reloading by simply starting wire
into guide tube. The drive rolls and guide tubes are
designed for long life and precise wire
feeding.
• Four-roll wire drive system available for additional
wire feeding force and easier feeding of soft wires
(LN-7 GMA model only).
• Completely enclosed case protects the heavy
duty wire drive mechanism from damage, but
allows easy access to drive rolls.
• Control circuit features “cold electrode” when
the gun trigger is released for an added measure of
safety.
• Low voltage (24 volts) gun trigger circuit.
• Dynamic braking system stops wire feed motor
quickly to minimize crater sticking problems.
• Three-year warranty on parts and labor.
