SAFETY PRECAUTIONS

WARNING
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts
such as output terminals or internal
wiring.
• When inching with gun trigger, electrode and
drive mechanism are "hot" to work and ground
and could remain energized several seconds
after the gun trigger is released.
• Turn OFF input power at welding power source
before installation or changing drive roll and/or
guide tubes.
• Welding power source must be connected to
system ground per the National Electrical Code
or any applicable local codes.
• Only qualified personnel should perform this
installation.

PRODUCT DESCRIPTION

The K316L-5 / LN-23P is a lightweight, portable wire feed
unit which includes calibrated wire speed control, voltage
control, wire drive with enclosed 14 lb. wire reel, analog
voltmeter and various input control and electrode cable
lengths.
The feeder is designed for welding with 14 pound coils of
.068 and 5/64 Innershield self-shielding electrodes using
a constant voltage type DC power Source. When
shipped, it is internally connected for welding with elec-
trode negative polarity (DC–). Depending upon which
gun and cable is used, its rating is either 350 amps or
250 amps at 60% duty cycle.
The wire speed control has a calibrated dial plate with a
range of 30 to 170 inches per minute and allows quick
and easy setting of the procedure wire feed speed. The
wire speed is not affected by changes in the arc voltage
setting even though the wire feed circuit is powered by
arc voltage. A two-position switch, which is mounted on
the gun and a reduced speed circuit, allows selection of
the preset wire speed or 83% of the preset speed.
A low voltage gun trigger circuit turns both the power
source output and wire feed on and off*. The gun trigger
circuit is interlocked by a weld current sensing reed
switch so that while welding, the gun trigger switch does
not have to be held closed. The welding process is
stopped by pulling the gun away from the work. The elec-
trode remains cold until the gun trigger is operated.

OPERATION

* In an SAE-400 application, the power source output
does not turn off - the electrode remains hot even
when the gun trigger is not being operated.
The LN-23P includes a voltage control which controls the
power source output. Also included is an analog volt-
meter which allows easy setting of the procedure arc
voltage at the LN-23P.

LOADING THE WIRE REEL

• Lay the LN-23P flat with the wire reel cover up, unclip
the rubber retaining strap, and remove the cover.
• Remove the center clamping nut and the cover plate
from the wire reel.
• Unpack the 14-pound coil of wire. Be sure not to bend
the side tangs of the coil liner and straighten any
tangs that may have been bent.
• Place the coil on the wire reel so the coil will unwind
when it rotates in a clockwise direction.
• Remove the start end of the coil from its holding slot
in the coil liner, cut off the bent end, straighten the
first few inches and thread it through the wire feed
conduit connected to the wire enclosure until several
inches of electrode are exposed. Be careful not to
release the electrode until it is through the wire feed
conduit; otherwise, it may unwind and tangle.
• Be sure all the lower tangs of the coil liner are flush
against the back half of the wire reel and that none of
the upper tangs are bent in against the coil.
• Replace the reel cover plate and the center clamping
nut.
• Replace the cover of the wire reel enclosure and clip
the retaining strap in place.
• Pull about 2 feet of the exposed end of the electrode
through the wire feed conduit. Slide the insulator all
the way up on the wire feed conduit.
Make a single, free loop in the electrode and feed the
end into the section of wire feed conduit connected to
the gearbox. Press the gun trigger and push the elec-
trode into the drive rolls. Release the electrode as
soon as it is picked up by the drive rolls. Continue
feeding electrode until the excess length is fed
through the drive rolls. Watch the single loop and
guide it if necessary to make certain it untwists with-
out kinking. Do not feed electrode through cable at
this time. Slide insulator down on wire feed conduit
until it slips over section of conduit connected to gear-
box.
• Set the unit upright on floor, straighten the gun cable,
press the gun trigger, and feed electrode though the
gun and cable assembly.

DRIVE ROLL PRESSURE

• Do not adjust the drive roll pressure. If the idle roll
tension must be relieved temporarily, see
(Maintenance Section).
