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.			CORRECT WORK CLIP ATTACHED TO WORK

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 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.

INCORRECT WORK CLIP ATTACHED TO ROLL CAGE

HIGH FREQUENCY PROTECTION

CAUTION

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.
