SAFETY PRECAUTIONS
READ AND UNDERSTAND ENTIRE SECTION
BEFORE OPERATING MACHINE.
WARNING
• ELECTRIC SHOCK CAN KILL.
Unless using COLD FEED fea-
ture, when feeding with gun trig-
ger, the electrode and drive
mechanism are always electri-
cally energized and could
remain energized several sec-
onds after the welding ceases..
• Do not attach the work clip to the roll cage or
bottom skids. The work clip is energized any
time the output of the welding power source is
"ON", even when the feeder is not welding.
• Do not touch electrically live part or electrode
with skin or wet clothing.
• Insulate yourself from work and ground.
• Always wear dry insulating gloves.
• The serviceability of a product or structure uti-
lizing the LN™-15 wire feeder is and must be
the sole responsibility of the builder/user. Many
variables beyond the control of The Lincoln
Electric Company affect the results obtained in
using the LN™-15 wire feeder. These variables
include, but are not limited to, welding proce-
dure, plate chemistry and temperature, weld-
ment design, fabrication methods and service
requirements. The available range of the LN™-
15 wire feeder may not be suitable for all appli-
cations, and the builder/user is and must be
solely responsible for welding settings.
-----------------------------------------------------------------
• FUMES AND GASSES can be
dangerous.
• Keep your head out of fumes.
• Use ventilation or exhaust at the
arc, or both, to remove fumes
and gases from breathing zone
and general area.
-----------------------------------------------------------------
• WELDING SPARKS can cause
fire or explosion.
• Keep flammable material away.
-----------------------------------------------------------------
ARC RAYS can burn.
• Wear eye, ear and body protec-
tion.
