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.
** Tabled values are for operation at ambient temperatures of 104°F(40°C) and below. Applications above 104°F(40°C) may require cables
larger than recommended, or cables rated higher than 167°F(75°C).
RECOMMENDED CABLE SIZES (RUBBER COVERED COPPER - RATED 167°F or 75°C)**

INSTALLATION
LN-25™ IRONWORKER

SAFETY PRECAUTIONS
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™
IRONWORKER 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™ IRONWORKER 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™ IRONWORKER.
The LN-25™ IRONWORKER is rated IP23 and is
suitable for outdoor use.
The handle of the LN-25™ IRONWORKER 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™ IRONWORKER away from radio
controlled machinery. The normal operation of the
LN-25™ IRONWORKER may adversely affect the
operation of RF controlled equipment, which may
result in bodily injury or damage to the equipment.
