Lincoln Electric VANTAGE 400 (AU) - Manual (Page 17)

CONNECTION OF LINCOLN ELECTRIC
WIRE FEEDERS
Connection of LN-15 to the VANTAGE® 400 (AU)
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, the current sens-
ing circuit will cause the VANTAGE® 400 (AU)
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"
5. Set the MODE switch to the "CV-WIRE " position.
6. Set the "WIRE FEEDER VOLTMETER" switch to
either "+" or "-" as required by the electrode polari-
ty being used.
7. Set the "ARC CONTROL" knob to "0" initially and
adjust to suit.
8. Set the "IDLE" switch to the "AUTO" position.
9. When the gun trigger is closed, the current sens-
ing circuit will cause the VANTAGE® 400 (AU)
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.
A-7 INSTALLATION
VANTAGE® 400 (AU)
A-7
AUXILIARY POWER
The auxiliary power capacity is 14,000 watts Peak,
13,200 Watts Continuous of 50 Hz, three phase
power. The auxiliary power capacity rating in watts is
equivalent to volt-amperes at unity power factor. The
max permissible current of the 400 VAC output is 22
amps. Output voltage is within ± 10% at all loads up
to the rated capacity.
Single phase power is:
• 6,900 Watts Peak / 6,900 Watts Continuous, 50 Hz
230 Volts 1-Phase (Euro).
STANDBY POWER CONNECTIONS
The machine is suitable for temporary, standby or
emergency power using the engine manufacturer’s
recommended maintenance schedule.
The machine can be permanently installed as a
standby power unit for 400 VAC, 3 phase, 20 amp
service.
Connections must be made by a licensed electri-
cian who can determine how the power can be
adapted to the particular installation and comply
with all applicable electrical codes.
• Take necessary steps to assure load is limited
to the capacity of the VANTAGE® 400 (AU).
• Only a licensed, certified, trained electrician
should install the machine to a premises or resi-
dential electrical system. Be certain that:
• The installation complies with the National
Electrical Code and all other applicable electri-
cal codes.
• The premises is isolated and no feedback into
the utility system can occur. Certain laws
require the premises to be isolated before the
generator is linked to the premises. Check your
local requirements.
