Semiautomatic Wire Feeders
The LN-8 and LN-9 are semiautomatic wire feeders providing
dependable performance and reliable operation, making them ideal for
shop or field operations. For precise wire feeding and quality welds,
the LN-8 and LN-9 feature controlled wire feed speed and voltage
during starting for clean, positive starts and reduced stubbing,
skipping and spatter.
Solid state control compensates for wire drag and input line variations
to maintain accurate wire feed speed. These wire feeders are easy to
use with a quick release gun and cable connection for easy set up,
and large wire feed and voltage control knobs that are easy to adjust
with gloved hands.
