Lincoln Electric K2286-1, K471, K470, K514, K1802-1 manual Installation

B-2 INSTALLATION B-2

c.For L-Tec machines that require trigger lead con- nections to be made at a terminal strip located with- in the machine (L-Tec 225), a gun control cable with forked terminals is provided. Connect the terminat- ed leads to the terminal strip. For a machine that requires a twist-lock gun control cable connection, continue to use the L-Tec gun control cable provid- ed with the L-Tec wire feeder connector assembly. Connect the twist-lock plug to the proper receptacle on the machine.

K466-6, K466-7, K466-9 and K466-10 Installation (Wirematic, Hobart Series 2000 Feeders, SP100T Type and Lincoln 10 Series Feeders)

a.Remove brass cable connector (see Figure 1) from the connector kit and screw it onto the feeder end of the gun cable. Tighten the connection with the wrench provided.

b.Check that the molded gas plug fitting is sealing the gas fitting hole in the side of the feeder end handle.

c.Attach the gun control cable provided to the trigger connector on the front of the wire feeder.

LINER INSTALLATION AND TRIMMING INSTRUCTIONS Installation of (KP1932, KP1936 and KP1955 series liners)

a.Lay the gun and cable straight on a flat surface.

b.Make sure that the set screw in the connector end is backed out so as not to damage liner or liner

bushing. Remove and save the gas nozzle, nozzle insulator, and gas diffuser from the end of the gun tube assembly.

c.Insert a new untrimmed liner into the connector end of the cable. Be sure the liner bushing is stenciled appropriately for the wire size being used.

d.NOTE: For liners KP1950-7, KP1950-8, KP1955-1 and KP1955-2

Before fully seating the liner bushing, it will be nec- essary to trim the liner’s inner tube flush with the liner bushing using a sharp blade. After trimming, remove any burrs from inner tube and insure that the opening is fully open.

For all K466 connector kits except K466-3 and K466-4, tighten the set screw in the cable connec- tor.

or

For K466-3 and K466-4, screw in the connector cap provided in the kit until it seats on the face of the bushing. Then insert the appropriate piece of liner material into the connector cap and tighten the set screw. Three pieces of liner material are included in these connector kits to help guide the electrode through the connector cap. The piece with the smallest inner diameter is designed for .045” (1.2

mm) maximum diameter electrode. The next largest diameter is for 1/16” (1.6 mm) maximum diameter electrode. The largest diameter piece of liner mate- rial is for 5/64” (2.0 mm) maximum diameter elec- trode.

e.Be sure the cable is straight and then trim the liner to the length shown in Figure 1 (a gauge is includ- ed on the wrench provided with the connection kit for gauging the cut-off length on 300 and 400 amp gun tubes). Remove any burrs from the end of the liner.
