CONNECTION OF LINCOLN ELECTRIC WIRE FEEDERS

Connection of LN-7 or LN-8 to the RANGER® 305LPG

1.Shut the welder off.

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

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

4.Set the "MODE" switch to the "CV WIRE " posi- tion.

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

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

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

Connection of LN-15 to the RANGER® 305LPG

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:

•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 "AUTO" position.

Connection of the LN-25 to the RANGER® 305LPG

WARNING

Shut off welder before making any electrical con- nections.

------------------------------------------------------------------------

The LN-25 with or without an internal contactor may be used with the RANGER® 305LPG. See the appro- priate connection diagram in Section F.

NOTE: The LN-25 (K431) Remote Control Module and (K432) Remote Cable are not recommended for use with the RANGER® 305LPG.

1.Shut the welder off.

2.For electrode Positive, connect the electrode cable from the LN-25 to the "+" terminal of the welder and work cable to the "-" terminal of the welder. For electrode Negative, connect the elec- trode cable from the LN-25 to the "-" terminal of the welder and work cable to the "+" terminal of the welder.

3.Attach the single lead from the front of the LN-25 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.

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

5.Set the "WELD TERMINALS" switch to "WELD

TERMINALS ON"

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.

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

MINALS ON"

•Control Cable Model:

Connect Control Cable between Engine Welder and Feeder.

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

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

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

7.Set the "IDLE" switch to the "AUTO" position. When not welding, the RANGER® 305LPG engine will be at the low idle speed. If you are using an LN-25 with an internal contactor, the electrode is not energized until the gun trigger is closed.

8.When the gun trigger is closed, the current sensing circuit will cause the RANGER® 305LPG engine to go to the high idle speed, the wire will begin to feed and the welding process started. When welding is stopped, the engine will revert to low idle speed after approximately 12 seconds unless welding is resumed.
