GENERAL DESCRIPTION
The MAGNUM® PRO 250, 350, 450 & 550 Amp and cable assemblies have been designed to meet specifi- cation for welding with steel electrode using the GMAW (gas metal arc welding) and gas-shielded FCAW (flux- cored arc welding) processes.
Most models of MAGNUM® PRO 250, 350, 450 & 550 Amp guns are not factory equipped with a feeder end connector. With the K466-1 MAGNUM® Connector Kit, they can be used with any Lincoln LN-7 or LN-25 semi- automatic wire feeder. The K466-1 should also be used with the LN-8 or LN-9 when feeding .052 and smaller electrodes. 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 250, 350, 450 AND 550 guns 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 MAGNUM® Connector Kit.
With the K466-3 or K466-4 MAGNUM® connector kits, it is possible to connect MAGNUM® PRO 250, 350, 450 & 550 Amp guns directly to a variety of Miller and Hobart wire feeders, respectively.
The K466-5 connector kit allows connection of MAG- NUM® PRO 250, 350, 450 & 550 Amp guns to an L Tec feeder connector assembly. L-Tec feeders require a feeder connector assembly (similar to a Tweco® adapter) in order to connect to a gun and cable. The K466-5 contains a brass connector to permit MAG- NUM® guns to be connected to this feeder connector assembly.
The K466-6 connector kit allows connection of MAG- NUM® PRO 250, 350, 450 & 550 Amp guns to a Lincoln Wirematic.
The K466-7 connector kit allows connection of MAG- NUM® PRO 250, 350, 450 & 550 Amp guns to Hobart Series 2000 Wire Feeders.
The K466-8 connector kit allows connection of MAG- NUM® PRO 250, 350, 450 & 550 Amp guns to an LN8 or LN9 when 1/16 and larger electrode is used.
The K466-9 connector kit allows connection of K497 to SP100T and related wire feeders.
The K466-10 connector kit allows connection of MAG- NUM® PRO 250, 350, 450 & 550 Amp guns to a 10 Series wire feeder. For best results when welding mild and alloy steels, it is recommended that L-50 or L-56 Lincoln solid wire electrodes be used for the GMAW process and OS70 or OS71 Lincoln Outershield cored electrodes for the gas-shielded FCAW process.
WARNING
•Do not touch electrically live parts such as output terminals or inter- nal wiring.
