INSTALLING THE LN-9 GMA

2-ROLL AND 4-ROLL MODELS

ATTACHING THE WIRE REEL STAND

Both the 2-Roll and 4-Roll LN-9 GMA are shipped with- out the wire reel stand attached. The screws and wash- ers for mounting the wire reel stand are included with the LN-9 GMA (fastened in their respective mounting holes). To attach the stand:

1.Remove the three 3/8" hex screws from the back of the wire feed unit.

2.Place the wire reel stand mounting bracket in posi- tion against the back of the wire feed unit.

3.Replace and tighten the screws. The long screw and plain washer go into the top hole. For 4-Roll feeders, one plain washer is used for mounting 60# wire stands and 2 plain washers for mounting 30# stands.

MOUNTING THE CONTROL bOX

The same control box is used for both the 2-Roll and 4- Roll wire feed unit. It contains two keyhole slots and one slot for mounting. Refer to the LN-9F GMA Dimension Print in the Diagrams section of this manu- al for the size and location of these slots. Mount the box at some convenient location close to the wire feed unit. This will enable the 16-foot control cable assem- bly supplied with both the LN-9F GMA 2-Roll and 4-Roll to reach between the control box and the wire feed unit.

1.Drill the required holes in the mounting surface. Partially install 1/4-20 screws.

2.Open the control box door by removing the two door screws.

3.Mount the box.

4.Tighten the screws.

5.Close the control box door and replace the door screws.

MOUNTING THE UNIT

LN-9 GMA wire feeders can be mounted directly on top of their power source as long as it is secure and level. When portability is required, the LN-9 GMA can be mounted on a K163 undercarriage See the Accessories section for details.

A K178-1 swivel platform is available for mounting the LN-9 GMA to the power source. See the Accessories section for details.

INSTALLING THE LN-9F GMA 2-ROLL AND 4-ROLL MODELS

MOUNTING THE WIRE FEED UNIT

Mount the wire feed unit by means of the insulated mounting bracket attached to the bottom of the gear- box. Refer to the LN-9F GMA Dimension Print in the Diagrams section of this manual for the size and loca- tion of the mounting holes. The gearbox assembly is electrically "hot" when the gun trigger is pressed. Therefore, make certain the gearbox does not come in contact with the structure on which the unit is mounted. The wire feed unit should be mounted so that the drive rolls are in a vertical plane so dirt will not collect in the drive roll area. Position the mechanism so it will point down at about a 45o angle so the wire feed gun cable will not be bent sharply as it comes from the unit.

CONNECTING THE WIRE FEED UNIT TO THE CONTROL bOX

Both the LN-9F GMA 2-Roll and 4-Roll include the same 16 ft. control and electrode cable assembly. Connect the wire feed unit to the control box as follows:

1.Make certain the cables are protected from any sharp corners that may damage their jackets. Mount the cable assembly along the boom so the end with the female amphenol connector pins is at the wire feed unit.

2.Connect the cable connector to the receptacle on the back of the wire feed unit connection box.

3.At the same end, connect the electrode lead to the connection stud of the copper strap along the side of the wire feed unit.

4.At the control box end, connect the amphenol con- nector of the control cable to the mating MS-type receptacle on the bottom of the control box. (See Figure A.3, later in this section, for the location of this connection.)
