Lincoln Electric 400 (AU) manual Auxiliary Power, Across The-Arc Model, Control Cable Model

A-7 INSTALLATION 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

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:

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.

WARNING

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.

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

•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.
