MAKING A WELD

• 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 instruc-
tions.)
• Place the LN-15 conveniently near the work area in
a safe location to minimize exposure to weld spatter
and to avoid sharp bends in the gun cable.
• Connect the LN-15 work clip to the work.
• Configure the feeder for either CV or CC, as appro-
priate for the power source. (The LN-15 is set to CV
by default.) Adjust the wire feed speed knob for the
welding procedure.
• 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 .40" (10mm)
of the end of the contact tip for solid wire and within
.75" (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.
