CONNECTOR KIT INSTALLATION TO GUN
CABLE
The K574 and K1722 Magnum® 400 dual procedure
cables are shipped as generic assemblies and must
be assembled with a connector kit.
NOTE: The K574 Magnum® 400 DP gun and cable is
not only shipped with a generic wire feeder end, it
is also shipped with generic gun control assem-
blies. The brass connector can be installed per
K466 instructions, but the gun control cable must
be tailored, by the user, to the specific machine.
To install on an LN-9 Lincoln wire feeder equipped
with a dual procedure kit, connect the cable marked
"1" to pin receptacles "A" and "C" of a S12020-6
five pin Amphenol plug (optional). (S12024-1 cable
clamp is required to secure the Amphenol plug to
the cable.) Connect the cable marked "2" to pin
receptacles "A" and "C" of a S12020-16 three pin
Amphenol plug (optional). (S12024-4 cable clamp
is required to secure Amphenol plug to the cable.)
To install on a DH-10 Lincoln wire feeder, a
S12024-12 cable clamp and a S12020-6 five pin
Amphenol plug are required. Slip the two control
cables through the cable clamp and connect the
two control cables to the Amphenol plug. Connect
the two leads of cable marked “1" to pins A & C and
connect the two leads of cable marked “2" to pins D
& E. Connect the cable clamp to the plug and
secure the leads.
The K1722 Magnum® 400DP gun and cable is
equipped with a control cable that attaches to a
Lincoln -10 series wire feeder. For other wire feed-
ers the control cable has to be rewired with the
appropriate connectors to fit the wire feeder.
K466-1& -8 INSTALLATION (For Lincoln Feeders)
a. Remove brass cable connector and insulation tube
(see Figure B.1) from the kit. Slide the insulation
tube onto the connector from the threaded end and
screw it onto the feeder end of the gun cable.
Tighten the connection with the wrench provided.
b. Remove the molded gas plug fitting on the side of
the feeder end handle and replace it with the
barbed brass fitting provided in the kit. The includ-
ed wrench will fit both the gas plug and barbed fit-
ting.
c. The gun control cable provided is not used.
d. Place one tubing clamp onto each end of the flexi-
ble tubing provided, approximately 2” (51 mm) in
from each end. Slide one end of the tubing onto the
barbed connector on the feeder end cable handle
(step b) and move the clamp down near the end of
the tube to ensure a good gas seal.
NOTE: An optional K481 Magnum® Fast-Connect
Gas Tube Kit is available to provide tool-less gas
tube connection to Lincoln wire feeders. Install per
the instructions included with the kit.
K466-2 INSTALLATION (For Adapted Feeders and
-10 Series Lincoln Feeders)
a. Remove brass cable connector (see Figure B.1)
from the kit and screw it onto the feeder end of the

provided.
b. Check that the molded gas plug fitting is sealing
the gas fitting hole in the side of the feeder end
handle.
