INSTALLATIONA-4

Install the barbed fitting and union nut to the 58-18 female inert gas fitting on the front panel of the LN-25 case. Connect the 316” I.D. gas hose from the gun cable to the barbed fitting.

When the gun is to be removed, this fitting can be easily detached by loosening the union nut.

WELD CABLE CONNECTION

The size of the electrode cable and work cable must be sufficient for the maximum weld current and total cable length to be used. Refer to table A.1.

ELECTRODE CABLE CONNECTION

On units without an internal contactor route the electrode cable through the oval hole in the LN-25 rear panel, then along the case floor behind the reel support and around the door side of the wire drive. Connect the electrode cable to the LN-25 using the

12” bolt on the front of the wire drive.

On units with an internal contactor connect the electrode cable to the LN-25 electrode input cable with the nut and bolt provided. Tape the bolted connection.

WORK CABLE CONNECTION

Connect a work lead of sufficient size between the proper output stud on the power source and the work. Be sure the connection to the work makes tight metal-to-metal electrical contact. Poor work lead connections can result in poor welding performance.

WIRE FEED DRIVE ROLL AND GUIDE TUBE KITS

WARNING

Turn off power source before installing or changing drive roll and/or guide tubes.

NOTE: The maximum wire sizes the LN-25 will satisfactorily feed are 564” cored and 116” solid electrodes.

The electrode sizes that can be fed with each roll and guide tube are stencilled(1) on each part. Check the kit for proper components. See the instructions, included with the drive roll kit, to install these parts on new machines or replace them on used machines. Refer to table A.2.
