LN™-15 ACROSS THE ARC MODEL & (CE)
MAKING A WELD
The serviceability of a product or structure utilizing the
LN™-15 wire feeder is and must be the sole responsi-
bility 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
procedure, plate chemistry and temperature, weld-
ment design, fabrication methods and service require-
ments. The available range of the LN™-15 wire feed-
er may not be suitable for all applications, and the
builder/user is and must be solely responsible for
welding settings.
• Close the door on the LN™-15.
• Connect the work cable to the metal to be welded.
The work cable must make good electrical contact to
the work. The work must also be grounded as stated
in "Arc Welding Safety Precautions".
• Connect the LN™-15 electrode cable to the power
source for the polarity and process to be used.
Check that the appropriate power source settings
are made for the procedure to be used. (Refer to the
power source operating and connection instructions.)
• Place the LN™-15 conveniently near the work area
in a safe location to minimize exposure to weld spat-
ter and to avoid sharp bends in the gun cable.
• Connect the LN™-15 work clip to the work.
• Be sure the proper contact tip for the wire size being
used is in the gun.
• Turn on the welding power source, as well as the
shielding gas supply (if used.)
• Cut the electrode within approximately 3/8" (10mm)
of the end of the contact tip for solid wire and within
3/4" (19mm) of the extension guide for cored wire.
• Position the electrode over the joint. The end of the
electrode should be slightly off the work.
• Lower welding helmet, close the gun trigger and
begin welding. Hold the gun so the contact tip to
work distance gives the correct electrical stickout as
required for the procedure being used.
• To stop welding, release the gun trigger and the pull
the gun away from the work.
