B-10 OPERATION B-10
To Mount a 50-60 Lb. (22.7-27.2 kg) Coil:
(Using K1504-1 Coil Reel)
(For 50-60 lb Readi-
Reels a K438 Readi-Reel Adapter must be used).
The Spindle must be located in the UPPER mounting hole.
1) With the K1504-1 Coil Reel mounted on to the 2"
(51 mm) spindle (or with reel laying flat on the
floor) loosen the spinner nut and remove the reel
cover. (See Figure B.2).
2) Before cutting the tie wires, place the coil of elec-
trode on the reel so it unwinds from the bottom as
the reel rotates.
3) Tighten the spinner nut against the reel cover as
much as possible by hand using the reel cover
spokes for leverage. DO NOT hammer on the
spinner nut arms.
4) Cut and remove only the tie wire holding the free
end of the coil. Hook the free end around the rim
of the reel cover and secure it by wrapping it
around. Cut and remove the remaining tie wires.
Always be sure the free end of the coil is securely
held while the tie wires are being cut and until the wire
is feeding through the drive rolls. Failure to do this will
result in “backlashing” of the coil, which may tangle
the wire. A tangled coil will not feed so it must either
be untangled or discarded.

5) Be sure the coil reel is engaged with the spindle
brake pin and the Release Bar on the Retaining
Collar “pops up” and that the collar retainers fully
engage the retaining groove on the spindle.

FEEDING ELECTRODE AND BRAKE
ADJUSTMENT
1) Turn the Reel or spool until the free end of the
electrode is accessible.
2) While tightly holding the electrode, cut off the bent
end and straighten the first 6" (150 mm). Cut off
the first 1" (25 mm). (If the electrode is not proper-
ly straightened, it may not feed or may jam causing
a "birdnest".)
3) Insert the free end through the incoming guide
tube.
4) Press the Cold Inch key or the Cold Feed Mode
gun trigger and push the electrode into the drive
roll.
When feeding with the gun trigger, unless “COLD
FEED” trigger mode is selected, the electrode and
drive mechanism are always “HOT” to work and
ground and could remain “HOT” several seconds after
the gun trigger is released.
___________________________________________
5) Feed the electrode through the gun.
6) Adjust the brake tension with the thumbscrew on
the spindle hub, until the reel turns freely but with
little or no overrun when wire feeding is stopped.
Do not overtighten.
DRIVE ROLL PRESSURE SETTING
The LN-10 pressure is factory pre-set to about posi-
tion “2" as shown on the pressure indicator on the
front of the feedplate door. This is an approximate
setting.
The optimum drive roll pressure varies with type of
wire, surface condition, lubrication, and hardness.
Too much pressure could cause “birdnesting”, but too
little pressure could cause wire feed slippage with
load and/or acceleration. The optimum drive roll set-
ting can be determined as follows:
LN-10
SPINNER NUT
COVER
PLATE
SLOTS
CARDBOARD
COIL LINER

TIE WIRE
SPRING
LOADED ARM
