SAFETY PRECAUTIONS
ELECTRIC SHOCK CAN KILL.
• ONLY QUALIFIED PERSONNEL
S H O U L D P E R F O R M T H I S
INSTALLATION.
• Turn off input power to the power
source at the disconnect switch
or fuse box before working on
this equipment. Turn off the input power to any
o t h e r e q u i p m e n t c on n e c t e d t o t h e w e l di n g
system at the disconnect switch or fuse box
before working on the equipment.
• Do not touch electrically hot parts.
• Do not touch metal portions of the LN™-15
work lead clip when the welding power source
is on.
• Do not connect the LN™-15 to a non-Lincoln
TIG power source, a SQUARE WAVE TIG power
source, or a PLASMA CUTTING power source.
-------------------------------------------------------------------
LOCATION
The LN™-15 should be positioned upright on a
horizontal surface. Do not submerge the LN™-15 in
water. The best practice is to keep the wire feeder in
a dry environment. When working outdoors in severe
wet weather, place the LN™-15 with the door facing
up.

INSTALLATION.
• Do not touch metal portions of the
LN™-15 work clip lead when
the welding power source is on. The work clip
lead is electrically "hot" to work if the input
electrode cable to the LN™-15 is electrically
"hot", even if the gun trigger is off. Care should
be taken to only handle the LN™-15 work clip
lead by its nonmetal insulated portions and/or
the welding power source should be turned off
before handling the work clip.
• Do not attach the work clip lead to the roll cage
or bottom skids of the LN™-15.
• Attach the work clip only to the work piece.
-------------------------------------------------------------------
** The work clip lead is present only on Across-the-
Arc models.
The work clip lead attached to the front of the LN™-
15 must be connected directly to the work using the
spring clip on the end of the lead.
If the work clip lead is not connected, the LN™-15 will
not operate.
The work clip lead also serves as a work sensing lead
for the LN™-15. If the work clip lead is extended by
the user beyond the standard 15' (4.6m) length, the
voltmeter reading will be lower than the actual arc
volts due to resistance in the extended lead. To mini-
mize the error, the following lead size is recommend-
ed for the maximum extended lengths shown.
AWG Max. Length
#14 25 ft (7.6m)
#12 50 ft (15.2m)
#10 100 ft (30.5m)
#6 200 ft (61.0m)
CORRECT WORK CLIP ATTACHED TO WORK
INCORRECT WORK CLIP ATTACHED TO ROLL CAGE
HIGH FREQUENCY PROTECTION
To prevent possible damage to the LN™-15, do
not connect the LN™-15 to non-Lincoln TIG or
SQUARE WAVE power sources. TIG high frequen-
cy should never be applied to the LN™-15.
-------------------------------------------------------------------
Locate the LN™-15 away from radio controlled
machinery. The normal operation of the LN™-15 may
adversely affect the operation of RF controlled equip-
ment, which may result in bodily injury or damage to
the equipment total.
