CONNECTION OF LINCOLN ELECTRIC WIRE FEEDERS

Connection of LN-7 or LN-8 to the RANGER 305D

•Shut the welder off.

•Connect the LN-7 or LN-8 per instructions on the appropriate connection diagram in Section F.

•Set the "WIRE FEEDER VOLTMETER" switch to either "+" or "-" as required by the electrode being used.

•Set the "MODE" switch to the "CV WIRE " position.

•Set the "ARC CONTROL" knob to "0" initially and adjust to suit.

•Set the "WELD TERMINALS" switch to the "REMOTELY CONTROLLED" position.

•Set the "IDLE" switch to the "HIGH" position.

Connection of LN-742, Spool Gun(K487-25SG)and Cobramatic to RANGER 305D

•Shut the welder off.

•Connect per instructions on the appropriate connec- tion diagram in Section F.

Connection of LN-15 to the Ranger 305D

These connections instructions apply to both the LN-

15Across-The-Arc and Control Cable models. The LN-15 has an internal contactor and the electrode is not energized until the gun trigger is closed. When the gun trigger is closed the wire will begin to feed and the welding process is started.

•Shut the welder off.

•For electrode Positive, connect the electrode cable to the "+" terminal of the welder and work cable to the "-" terminal of the welder. For electrode Negative, connect the electrode cable "-" terminal of the welder and work cable to the "+" terminal of the welder.

•Across-The-Arc Model:

Attach the single lead from the front of the LN-15 to work using the spring clip at the end of the lead. This is a control lead to supply current to the wire feeder motor; it does not carry welding current.

•Control Cable Model:

Connect Control Cable between Engine Welder and Feeder.

•Set the MODE switch to the "CV-WIRE " position.

•Across-The-Arc Model:

Set the "WELD TERMINALS" switch to "WELD TER-

MINALS ON"

Control Cable Model:

Set the "WELD TERMINALS" switch to "REMOTELY CONTROLLED"

•Set the "WIRE FEEDER VOLTMETER" switch to either "+" or "-" as required by the electrode polarity being used.

•Set the "ARC CONTROL" knob to "0" initially and adjust to suit.

•Set the "IDLE" switch to the "High" position

Connection of an LN-23P Wire Feeder to the RANGER 305D

•Shut the welder off.

•Connect the LN-23P as per instructions on the appropriate connection diagram in Section F. (NOTE): When connecting an LN-23P to the RANGER 305D, a K350-1 adapter kit must be used.

•Set the "VOLTMETER" switch to "-".

•Set the "MODE" switch to "CV WIRE " position.

•Set the "WELD TERMINALS" switch to "REMOTELY CONTROLLED".

•Set the "ARC CONTROL" knob to "0" initially and adjust to suit.

•Set the "IDLE" switch to the "AUTO" position. When not welding, the RANGER 305D engine will be at the low idle speed. If you are using an LN-23P with the K350-1 adapter kit, the electrode is not energized until the gun trigger is closed. When the gun trigger is closed, the current sensing circuit will cause the RANGER 305D engine to go to the high idle speed, the wire will begin to feed and the welding process can be started. When welding is stopped, the engine will revert to low idle speed after approximately 12 seconds unless welding is resumed.
