ROUTING THE ELECTRODE

The electrode supply may be either from reels, Readi-
Reels, spools, or bulk packaged drums or reels.
Observe the following precautions:
• The electrode must be routed to the wire feed unit so
that the bends in the wire are at a minimum. The
force required to pull the wire from the reel into the
wire feed unit must be kept at a minimum.
• The electrode is "hot" when the gun trigger is
pressed and must be insulated from the boom and
structure.
• If more than one wire feed unit share the same
boom, their wire and reels must be insulated from
each other and insulated from their mounting struc-
ture.
See the Accessories section for information about a
K299 wire reel assembly.

POWER INPUT CABLE ASSEMBLY

A special cable assembly is required to connect all LN-
9 models to the power source. The assembly includes
control cable and electrode cable. Various sizes are
available, based on length and maximum welding cur-
rent. The following power source cable assemblies are
available:
K196 for Terminal Strip control connection and output
terminal.
K595 for 14-Pin receptacle and output terminal.
K596 for 14-Pin receptacle and "Twist-Mate" connec-
tion.
NOTE: Use of an LN-9 with a Pulse Power 500 or a
DC650 PRO requires a K442-1 Pulse Power Filter Kit.
INSTALLATION
CONNECTING THE POWER INPUT
CABLE ASSEMBLY TO THE LN-9N or
LN-9S WIRE FEED UNIT
The K196, K595, or K596 cable assembly consists of
an electrode cable and multiconductor control cable.
The control cable has a MS-type plug on the wire feed-
er end. To install:
1. See Figure A.1. Connect the MS-type plug of the
control cable to the mating connector on the back
of the wire feeder.
2. See Figure A.2. Remove the screws holding the
cable strain relief clamp located near the rear of
the wire reel stand base. Put the control cable and
the electrode cable under the clamp and install the
screws.
For cables with more than one electrode cable,
leave the junction between the two or more cables
and the single 4/0 stub behind the clamp so that
only the single electrode lead is under the clamp.
3. See Figure A.1. Pass the single electrode cable
through the hole provided in the back corner of the
control section and fasten it to the copper strap on
the wire drive unit.
