CONNECTION OF LINCOLN ELECTRIC WIRE FEEDERS

WARNING

Shut off welder before making any electrical con- nections.

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

CONNECTION OF LN-7, LN-8 OR LN-742

TO THE VANTAGE 500 CUMMINS

•Shut the welder off.

•Connect the LN-7, LN-8 OR LN-742 per instructions on the appropriate connection diagram in the DIA- GRAMS section.

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

•Set the “SELECTOR” switch to the “CV-WIRE” posi- tion.

•Adjust the “ARC CONTROL” knob to desired Crispness. SOFT for MIG and CRISP for Innershield.

•Set the “WELDING TERMINALS” switch to the “REMOTELY CONTROLLED” position.

•Set the “IDLE” switch to the “HIGH” position.

CONNECTION OF LN-15 TO THE VAN- TAGE 500 CUMMINS

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 cur- rent.

•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

TERMINALS ON"

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

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

Set the "IDLE" switch to the "AUTO IDLE" posi- tion.

•Control Cable Model:

Set the "WELD TERMINALS" switch to

"REMOTELY CONTROLLED"
