GENERAL DESCRIPTION
The MAGNUM® & MAGNUM® PRO CURVE 200
amp GMA gun and cable assembly has been
designed to meet NEMA specification EW3 for weld-
ing with steel electrode using the GMAW (gas metal
arc welding) and gas-shielded FCAW (flux-cored arc
welding) processes: See Table B.1 and Table B.2.
The K497 MAGNUM® & K2950 MAGNUM® PRO
CURVE gun is not factory equipped with a feeder
end connector. With the K466-1 MAGNUM®
Connector Kit, it can be used with any Lincoln LN-7,
LN-8, LN-9, SP200 or LN-25 semiautomatic wire
feeder. An optional K481 MAGNUM® Fast-Connect
Gas Tube Kit is available to provide tool-less gas tube
connection to Lincoln wire feeders. Non-GMA model
wire feeders require an optional gas solenoid valve.
The K497 gun can also be used with any wire feeder
equipped with a Tweco
® # 1, 2, 3, 350 or 4 wire feed
adapter kit by using the K466-2 Adapted Feeder
Connector Kit.
A K466-3, Miller Feeder Connector Kit allows connection
of the MAGNUM® & MAGNUM® PRO CURVE to
popular Miller wire feeders.
A K466-4, Hobart Feeder Connector Kit allows con-
nection of the MAGNUM® & MAGNUM® PRO
CURVE to popular Hobart wire feeders.
A K466-5, L-Tec Feeder Connector Kit allows connec-
tion of the MAGNUM® & MAGNUM® PRO CURVE to
popular L-Tec wire feeders.
For best results when welding mild and alloy steels, it
is recommended that Lincoln solid wire electrodes be
used for the GMAW process and OS71 Lincoln
Outershield
® cored electrodes for the gas-shielded
FCAW process.
