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™ PRO
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™ PRO on a stable and dry surface.
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™ PRO.

LN-25™ PRO
The LN-25™ PRO is rated IP23 and is suitable for
outdoor use.
The handle of the LN-25™ PRO 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
Locate the LN-25™ PRO away from radio controlled
machinery. The normal operation of the LN-25™
PRO may adversely affect the operation of RF con-
trolled 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 various 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 voltage drop in the cables.
