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 wire feeder in a dry environment. When working outdoors in severe wet weather, place the LN™-15 with the door facing up.

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.

CORRECT WORK CLIP ATTACHED TO WORK

WARNING

WORK CLIP LEAD

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 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.
