CONNECTION OF LINCOLN ELECTRIC WIRE FEEDERS

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

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 305G

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.

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.

•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 305G

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 305G. See the appropriate 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 305G.

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"

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