Most models of MAGNUM® PRO 250, 350, 450 & 550
Amp gun cables are shipped as generic assemblies
and must be assembled with a K466 connector kit (See
REPLACEMENT PARTS P-202 series, section Chart E
for proper kit).

a. Remove brass cable connector and insulation tube
(see Figure B.1) from the K466-1 kit. Slide the insu-
lation 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 pro-
vided.
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 included wrench
will fit both the gas plug and barbed fitting.
c. Attach the round connector of the gun control cable
provided to the trigger connector on the front of the
Lincoln feeder. ("#( Both the plug and socket
are keyed and must be properly oriented.)
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.
