Be sure the connection to the work makes tight metal
to metal electrical contact. Poor work lead connec-
tions can result in poor welding performance.

POWER SOURCE CONNECTION
The LN-15 can be used with any DC welding power
source. A constant voltage power source is recom-
mend; however, the LN-15 can also be used with a
constant current power source as long as the open
circuit voltage is less than 110VDC.

Although a constant voltage (CV) power source is recommended for best results with Innershield® and gas
metal arc (GMAW) open arc welding, satisfactory general purpose welding may be obtained using the LN-15
with a constant current (CC) power source for non-critical commercial quality mild steel welding applications.

based on the material to be welded. The intention is to
assure that proper weld material properties will develop.

Welding is sometimes performed using constant current
power sources. The operation can be more convenient
because it may allow the use of an existing stick (SMAW)
power source and the power source can be placed at a
distant location without any provision for adjusting the
output settings.

For constant current operation, the power source is set to
deliver the specified current. The power source regulates
this current regardless of changes in the welding circuit,
including cable length, electrode diameter, wire feed
speed, contact tip to work distance, etc.

Changes in the wire feed speed (WFS) or contact tip
to work distance (CTWD) affect the arc voltage when
constant current power sources are used. Lowering
the wire feed speed raises the voltage, raising the
wire feed speed lowers the voltage. Lengthening the
contact tip to work distance raises the voltage, short-
ening the contact tip to work distance lowers the volt-
age.

OPERATION
MAKING A WELD

The serviceability of a product or structure utilizing the
LN-15 wire feeder is and must be the sole responsibil-
ity of the builder/user. Many variables beyond the con-
trol of The Lincoln Electric Company affect the results
obtained in using the LN-15 wire feeder. These vari-
ables include, but are not limited to, welding proce-
dure, plate chemistry and temperature, weldment
design, fabrication methods and service requirements.
The available range of the LN-15 wire feeder 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 spatter
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.

MAINTENANCE
SAFETY PRECAUTIONS
WARNING
ELECTRIC SHOCK can kill.
�? Do not operate with covers
removed.
�? Turn off power source before
installing or servicing.
�? Do not touch electrically hot
parts.

�? Turn the input power to the welding power
source off at the fuse box before working in the
terminal strip.
�? Only qualified personnel should install, use or
service this equipment.

ROUTINE MAINTENANCE
Routine maintenance consists of periodically blowing
out the machine, using a low pressure airstream, to
remove accumulated dust and dirt from inside the
feeder.

PERIODIC MAINTENANCE
�? Replace the drive rolls and inner wire guide when
they are worn.

�? Replace the pig tail if the insulation is cut, abraded
or damaged.

CALIBRATION SPECIFICATION
All calibration is factory set on the LN-15.

To verify the wire feed speed:
�? Assemble a .045 (1.2mm) drive roll kit into the LN-
15.
�? Load a spool of .045 (1.2mm) electrode and thread
the electrode through the wire drive.
�? Adjust the wire feed speed to 300 in/min
(7.62m/min).
�? Press the COLD FEED switch and measure the
actual wire feed speed with a calibrated wire feed
speed tachometer.
�? The measured wire feed speed should be within 2%
of the set value.

To verify the voltage display:
�? Set the welding power source and LN-15 to a CV
procedure that gives steady "spray" transfer in the
arc.
�? While a weld is being made, measure the voltage
from the feed plate to work.
�? The displayed voltage on the LN-15 should be with-
in 2% of the measured value.
