CONNECTION OF LINCOLN ELEC-
TRIC WIRE FEEDERS
Shut off welder before making any electrical con-
nections.
------------------------------------------------------------------------
Connection of LN-7, LN-8 OR LN-742 to the AIR
VANTAGE
® 650 CUMMINS
1. Shut the welder off.
2. Connect the LN-7, LN-8 OR LN-742 per instruc-
tions 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 AIR VANTAGE ® 650
CUMMINS
These connections instructions apply to both the LN-
15 Across-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.
1. Shut the welder off.
2. For electrode Positive, connect the electrode
cable to the "+" terminal of the welder and work
cable to the "-" terminal of the welder. For elec-
trode Negative, connect the electrode cable to the
"-" terminal of the welder and work cable to the "+"
terminal of the welder.
3. 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
TERMINALS ON".
• When the gun trigger is closed and an arc has
been struck, the current sensing circuit will cause
the AIR VANTAGE
® 650 CUMMINS 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.
4. 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 polar-
ity being used.
• Set the "ARC CONTROL" knob to "0" initially and
adjust to suit.
• Set the "IDLE" switch to the "AUTO" position.
• When the gun trigger is closed and an arc has
been struck, the current sensing circuit will cause
the AIR VANTAGE
® 650 CUMMINS 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.
