K320 FLUX TANK
Either turn off the incoming air line or remove the quick
disconnect if one has been installed. Slightly loosen
the tank cap and let the air in the tank escape in the
holes in the side of the cap. After pressure has been
released, remove the cap from the tank. Using the
funnel provided, put 100 pounds of flux in the tank. It is
very important that only new or properly reclaimed flux
be put in the tank. Coarse particles and/or magnetic
particles will stop the flux feeding process. New Lincoln
flux is properly screened at the factory. All reclaimed
flux must be separately screened through a vibrating
screen with 0.065 in. to 0.075 in. openings and be put
through a magnetic separator. The K310 vibrated
screen and K58 magnetic separator are available for
this purpose. The screen in the funnel supplied with the
tank has much larger openings and its only purpose is
to keep paper and slag out of the tank.
There will always be a small amount of air and possible
drops of water coming out of the end of the tube coiled
under the tank. This is an automatic disposal system in
case the plant air has water and dirt in it.
POWER INPUT CABLES
A variety of power input cable assemblies are avail-
able for various current ratings and power source con-
nection types. All provide a polarized control cable
plug and a lugged electrode cable for connection to
the wire feeder.
K591 INPUT CABLE
Consists of an eight-conductor control cable with 14-
pin control cable plug and a 2/0 (67 mm
2 ) electrode
cable with Twist-Mate TM connector. It is rated at 400
amps, 60% duty cycle, and is available in lengths of
10, 25
,
and 50 feet (3.0, 7.6, and 15.2 m).
K592 INPUT CABLE
Consists of an eight-conductor control cable with 14-
pin control cable plug and a 3/0 (85 mm
2 ) electrode
cable with stud terminals. It is rated at 600 amps, 60%
duty cycle, and is available in lengths of 10, 25, and
50 feet (3.0, 7.6, and 15.2 m).
K593-10 INPUT CABLE AND
GAS HOSE
Similar to the K591, but includes a gas hose with a
5/8-18 male fitting for the LN-742 inlet, and water
hoses with 5/8-18 left-hand male fittings to connect
between the water cooler and an LN-742 equipped
with the optional K590-1 water solenoid kit. It is rated
at 400 amps, 60% duty cycle, and is available in a 10
ft (3.0 m) length.
K619 INPUT CABLE
Consists of an eight-conductor control cable with 14-
pin control cable plug and a 1/0 (53 mm
2 ) electrode
cable with stud terminals. It is rated at 350 amps, 60%
duty cycle, and is available in lengths of 10, 25, and
50 feet (3.0, 7.6, and 15.2 m).
WELDING GUNS
GMAW GUNS
An expanding line of Magnum GMA gun and cable
assemblies are available to allow welding with solid
and cored electrodes using the GMAW process. See
the appropriate Magnum literature for descriptions of
the 200-400 ampere air cooled guns and cables that
are available. Gun cable lengths range from 10 to 25 ft.
(3.0 to 7.5 m) and feed electrode sizes 0.025 in. to 5/64
in. (0.6 to 2.0 mm).
