SAFETY PRECAUTIONS

WARNING

ELECTRIC SHOCK CAN KILL.

• Turn the input power OFF at the disconnect switch or fuse box before attempting to connect or disconnect input power lines, out- put cables or control cables.

Only qualified personnel should perform this installation.

Do not touch metal portions of the LN-25™ PIPE work clip when the welding power source is on.

Do not attach the work clip to the wire feeder.

Connect the work clip directly to the work, as close as possible to the welding arc.

Turn power off at the welding power source before disconnecting the work clip from the work.

Only use on power sources with open circuit voltages less than 110 VDC.

------------------------------------------------------------------------

LOCATION

For best wire feeding performance, place the LN- 25™ PIPE on a stable and dry surface. Keep the wire feeder in a vertical position. Do not operate the wire feeder on an angled surface of more than 15 degrees.

Do not submerge the LN-25™ PIPE.

The LN-25™ PIPE is rated IP23 and is suitable for outdoor use.

The handle of the LN-25™ PIPE is intended for moving the wire feeder about the work place only.

When suspending a wire feeder, insulate the hanging device from the wire feeder enclosure.

HIGH FREQUENCY PROTECTION

CAUTION

Locate the LN-25™ PIPE away from radio con- trolled machinery. The normal operation of the LN- 25™ PIPE may adversely affect the operation of RF controlled equipment, which may result in bodily injury or damage to the equipment.

WELD CAbLE SIzE

Table A.1 located below are copper cable sizes rec- ommended for different currents and duty cycles. Lengths stipulated are the distance from the welder to work and back to the welder again. Cable sizes are increased for greater lengths primarily for the purpose of minimizing cable drop.
