WORK CLIP LEAD
WARNING
ELECTRIC SHOCK can kill.
• Do not touch metal por-
tions of the LN-35 lead clip
when
source is on.
WARNING
IMPORTANT SAFETY NOTE: To avoid possible
electrical shock, do not touch the metal portions
of the LN-35 work lead clamp if the power source
output is on. The clamp will be electrically "HOT"
to work if the input electrode cable to the LN-35 is
electrically "HOT" even if the gun trigger is off.
Care should be taken to only handle the LN-35
work clamp by its non-metal insulated portions
and/or the welding power source should be turned
off before handling the work clamp.
--------------------------------------------------------------------
The 15 ft work clamp lead attached to the front panel
of the LN-35 case must be connected directly to the
work using the spring clamp on the end of the lead.
If not connected, the LN-35 will not operate. However,
the electrode will still be electrically "HOT" when the
clamp lead is disconnected.
WIRE REEL LOADING – 50 AND 60 LB
ADJUSTABLE WIRE REEL BRAKE
The mount for standard 50 and 60 pound electrode
coils includes a two-position brake assembly.
Generally the brake should be at the inner position
(nearest to the wire reel shaft) for wire feed speeds
below 400 in./min (10 m/min). It should be at the
outer position for the faster wire speeds often used
when feeding smaller diameter electrode.
To adjust the brake position, remove the wire reel.
Pull the cotter pin that holds the brake shoe to the
arm, move the shoe and replace the cotter pin. Do
not bend the cotter pin - it is held in place by a
friction fit.
OPERATION

TO MOUNT A 50 OR 60 LB COIL:
1. To remove the wire reel from its shaft.
2. Lay the reel flat on the floor. Loosen the spinner
nut and remove the cover plate. See Figure
B.1.
3. Place the coil of electrode on the reel so it
unwinds as the reel rotates clockwise. DO NOT
cut the tie wires at this time.
4. Be sure the coil is placed so the spring loaded
arms will not interfere with the later removal of
the coil tie wires.
5. When loading 0.030, 0.035, and 0.045"
electrode, be certain the coil is placed on the
reel so the spring loaded arms are at the center
of the slots in the cardboard coil liner. This
provides the positive compression of the coil
sides needed for trouble-free wire feeding.
6. Put the cover plate on the reel so the four arms
of the cover plate straddle and are in line with
the spring loaded arms of the reel.
7. Tighten the cover as much as possible by hand.
DO NOT hammer on the spinner nut arms.
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 "back
lashing" of the coil, which may tangle the wire.
A tangled coil will not feed. It must be untangled
or discarded.
-------------------------------------------------------------------
8. Cut and remove only the tie wire holding the
free end of the coil. Insert the free end into one
of the holes in the cover and secure it by
bending it back. Cut and remove the remaining
tie wires.
9. Replace the reel on the wire feeder.
