CONNECTING THE POWER INPUT CAbLE

ASSEMbLY TO POWER SOURCES

WARNING

CONNECTING THE POWER INPUT CAbLE ASSEMbLY TO THE LN-9F CONTROL bOX

1.See Figure A.3. Connect the polarized plug of the K196, K595, or K596 control cable to the mating MS-type connector on the bottom of the LN-9F GMA control box.

2.Bolt the electrode lead from the power source to the electrode lead to the wire feed unit using the nut and bolt supplied. Insulate the connection with elec- trical tape.

Turn input supply power to the power source OFF before connecting the LN-9 GMA or LN-9F GMA wire feeder.

Connect to an appropriate Lincoln power source as fol- lows:

1.If using a multipurpose source (such as the DC- 250, DC-400 and DC-600), be sure it is properly set for the welding process being used. See the topic "Making a Test Weld," in the Operation sec- tion of this manual.

For terminal strip connections using the K196 power input cable, connect the input cable to the power source exactly as specified on the appropriate LN-9 GMA model connection diagram:
