LN-9 Wire Feeder
WIRE FEEDER ACCESSORIES
BURNBACK DELAY KIT (K202)
Provides a precise control of the electrode burnback
at the end of the weld. Prevents crater sticking and
provides proper stickout for starting the next weld.
Recommended especially when welding with small
(.030-1/16") diameter wire at high wire feed speeds.
Also recommended when the semiautomatic gun is
mounted in a fixture or on the Squirtmobile in a way
that prevents the gun from lifting from the work at the
end of the weld.
Install the kit according to the instructions included
with the kit.
DUAL PROCESS KIT (K317) - For Wire Feeders
Using Same Polarity
This kit permits the connection of two wire feeders to a
single power source. Both feeders must weld with the
same electrode polarity. When the trigger of the
desired wire feeder is pressed, the power source out-
put control leads (#75, #76 and #77) will be connected
to that feeder, and the procedure as set on its controls
will be provided. The other connected wire feeder will
not be feeding wire, but its electrode circuit will be elec-
trically hot. The kit mounts at the power source and is
connected to the power source terminal strip with the
supplied leads. Standard K196 input cable assemblies
are used to connect each wire feeder to the dual
process control circuit while the electrode lead con-
nects to the power source.
Install the kit according to instructions included.
DUAL PROCESS KIT (K318) - With Electrode
Polarity Change Capability
Functions essentially the same as the K317 except that
the kit includes two contactors to provide different
polarities on the two wire feeders. When connected in
this manner and one trigger is pressed, the other elec-
trode will be "cold" to ground but "hot" to the other elec-
trode. This kit can also be connected to provide the
same polarities on each feeder, but the electrode circuit
of the one not being used will be cold to work and to the
other electrode.
Install the kit according to instructions included.
NOTE: The K317 and K318 Dual Process Kits also
include mode change capability, but only when using
the DC-600 power source. This feature permits one
feeder to weld in CV Innershield mode and the other
feeder to weld in CV Submerged Arc mode, as well as
both in the same mode.
When using the Pulse Power 500 power source, the
K317 or K318 Dual Process Kits can be used only if the
procedures are close enough to use the same mode
setting. The K317 or K318 cannot switch modes on the
Pulse Power 500. An LN-9 may not be used with an
LN-7 or LN-8, although two LN-9s may be used togeth-
er.
DUAL PROCEDURE KIT (K319)
With the use of this kit, one of two different settings of
wire feed speed and voltage can be selected by a tog-
gle switch mounted on the gun handle. The kit consists
of a control panel which mounts over the standard
LN-9 control rheostats. This control panel has four
rheostats, a transfer relay and a polarized connector.
During installation, the standard security door is mount-
ed over the new panel and functions in the same man-
ner. All electrical connections are with plugs to speed
and simplify the assembly. A 15-foot control cable with
a polarized connector on one end for plugging into the
new control panel is provided. On the other end of the
control cable is a small selector toggle switch and a
mounting bracket.
A K302 Extension Control Cable is required when
using the K319 with any LN-9F model.
Install the kit according to instructions included.
PULSE POWER FILTER CONVERSION KIT (K442-1)
Required for any LN-9 to be used with a Pulse Power
500 or DC650 Pro power source. Includes a Filter
Board and connection harness, easily installed in the
control section and plugged into the Voltage Board.
The plug must be disconnected for use with other stan-
dard power sources.
Install the kit according to instructions included.
