The Magnum® 250 NR FM guns are 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, and trig-
ger control leads to feeder.
NOTE: These guns are shipped with factory installed
liner. To change the liner in these models, see the sec-
tion on liner removal instructions in the Maintenance
section.
CONTACT TIP AND NOZZLE INSULATOR
INSTALLATION
a) Choose the correct size contact tip for the electrode
being used (wire size is stenciled on the side of the
contact tip) and screw it snugly into the gas less dif-
fuser.
NOTE: The contact tip for .068 diameter Innershield
electrode is stenciled 1/16A.
b) Be sure the nozzle insulator is fully screwed onto
the Gas less diffuser.
CONNECTION TO FAST-MATE COMPATIBLE
FEEDERS
FM model gun cable assemblies will connect easily to
any feeder equipped with a European style gun con-
nector, or any wire feeder equipped with a K489 Fast-
Mate Adapter Kit. Refer to Fast-Mate Adapter Chart A
in the ACCESSORIES section to determine the appro-
priate adapter required for various wire feeders.
1) Check that the feeder outgoing guide, as well as the
drive roll, are appropriate for the electrode size
being used. When using a Fast-Mate Adapter Kit, be
certain the adapter guide tube is also properly
sized.
2) Align and fully engage the brass connector end of
the gun cable into the mating connector on the out-
going side of the feeder wire drive. Secure the cable
connection by snugging the Fast-Mate connector
collar nut.
