GENERAL DESCRIPTION
The MAGNUM® 200FM amp GMA guna nd cable
assembly has been designed to meet NEMA specifi-
cation EW3 for welding with steel electrode using the
GMAW (gas metal arc welding) and gas-shielded
FCAW (flux-cored arc welding) processes:
The K498 MAGNUM® 200FM gun is factory installed
with a Fast-Mate (European style) wire feeder connec-
tor for “all-in-one” GMAW feeder connection. A single
connector attaches welding current, wire liner, welding
gas, and trigger control leads to feeder. An optional
K489-1 MAGNUM® Fast-Mate Adapter allows the use
of these guns with any Lincoln LN-7, LN-8, LN-9 and
SP200 wire feeder. An optional K489-2 MAGNUM®
Fast-Mate Adapter is required for the LN-25.
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 GMAW process
and OS70 or OS71 Lincoln Outershield
® cored elec-
trodes for the gas-shielded FCAW process.
