GENERAL DESCRIPTION
WARNING
• Do not touch electrically live parts
such as output terminals or internal
wiring
------------------------------------------------------------------------
The Magnum®™ 400 DP Dual Procedure FM gun and
cable assemblies have been designed to meet NEMA
specification EW3 for welding with steel electrode
using the GMAW (gas metal arc welding) and gas-
shielded FCAW (flux-cored arc welding) processes.
Magnum® 400 DP guns and cables are specifically
designed for use with wire feeders with dual proce-
dure capabilities. The K575 gun is equipped with a
two position trigger. Pulling the trigger in part of the
way will engage the first procedure set at the feeder.
Pulling the trigger the rest of the way will engage the
second procedure. An interlocking trigger is available
as a parts order. The K1723 Magnum® 400 DP Dual
Proecdure gun and cables are also designed for use
with wire feeders with dual procedure capabilities. The
guns are equipped with a rocker switch that is used to
select one of two welding procedures.
The Fast-Mate connector on the 400 Dual Procedure
guns has four pins (two for the trigger circuit and two
for the dual procedure circuit), and requires a dual
procedure adapter or a wire feeder that is compatible
with the 4 control pin connector. The K575 and K
1723 have a 4 pin Fast-Mate connector on the feeder
end of the gun. The four pin connector will interface
with the four pin receptacle on the K489-7 or K573-1
Adapter.
The Magnum® 400 DP gun and cable assemblies are
fully compatible for use with comparable Tweco gun
size tips, diffusers, gas nozzles, and cable liners. The
Magnum® FM gun family offers an expanding line of
quality, long life, expendable replacement parts and
accessories.
For best results when welding mild and alloy steels, it
is recommended that L-50 or Super Arc L-56 Lincoln
solid wire electrodes be used for the FMW process
and Lincoln Outershield cored electrodes for the gas-
shielded FCAW process.
