he LN-8 and LN-9 are semiautomatic wire feeders providing

T
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

o maintain accurate wire feed speed. These wire feeders are easy to

t
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.
