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
mounting a K299 wire reel assembly.
ELECTRICAL CONNECTIONS -
LN-9 GMA AND LN-9F GMA
POWER INPUT CAbLE ASSEMbLY
A special cable assembly is required to connect all LN-
9 GMA models to the power source. The assembly
includes control cable and electrode cable. Various
sizes are available, based on length and maximum
welding current. 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 GMA with a Pulse Power 500,
Invertec V300 or a DC650 PRO requires a K442-1
Pulse Power Filter Kit.

The K196, K595, or K596 cable assembly consists of
an electrode cable and multiconductor control cable.
The control cable has a polarized plug on the wire
feeder end. To install:
1. See Figure A.1. Connect the polarized plug of the

the wire reel stand base. Put the control cable and
the electrode cable under the clamp and install the

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.
