SAFETY PRECAUTIONS

WARNING
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 machine in a
dry environment. When using the LN-15 in severe
weather conditions, place the LN-15 on its side with
the door facing upwards. Keep the door closed.

WORK CLIP LEAD

WARNING
ELECTRIC SHOCK CAN KILL.
• ONLY QUALIFIED PERSONNEL SHOULD
PERFORM THIS 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 SKIDS OF THE LN-15.
-----------------------------------------------------------------------------------
** The work clip lead is present only on Across-the-
Arc models.
INSTALLATION
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 volt-
meter reading will be lower than the actual arc volts
due to resistance in the extended lead. To minimize
the error, the following lead size is recommended for
the maximum extended lengths shown.

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 FREQUENCY SHOULD
NEVER BE APPLIED TO THE LN-15.
------------------------------------------------------------------------------------------
Locate the LN-15 away from radio controlled machin-
ery. The normal operation of the LN-15 may adversely
affect the operation of RF controlled equipment, which
may result in bodily injury or damage to the equipment
total.
