SAFETY PRECAUTIONS
ELECTRIC SHOCK CAN KILL.
• ONLY QUALIFIED PERSONNEL
SHOULD PERFORM THIS
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 other equipment
connected to the welding 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.
HIGH FREQUENCY PROTEC-
TION
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 frequency 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.
WELD CABLE CONNECTIONS
ELECTRIC SHOCK CAN KILL.
• Only a qualified electrician should
connect the electrode leads to the
LN™-15. Connections should be
made in accordance with all local
and national electrical codes.
Failure to do so may result in bodily
injury or death.
------------------------------------------------------------------------
The size of the electrode cable and work cable must
be sufficient for the maximum weld current and total
cable length used. To avoid interference problems
with other equipment and to achieve the best possible
operation, route all cables directly to the work or wire
feeder. Avoid excessive lengths and do not coil
excess cable. Be sure the connection to the work
makes tight metal-to-metal electrical contact. (See
Table A.1)
