OPERATION

B-8

CV-WIRE MODE

Connect a wire feeder to the VANTAGE 500 CUM-

MINS and set welder controls according to the instruc-

tions listed earlier in this section.

The VANTAGE 500 CUMMINS in the ”CV-WIRE”

position, permits it to be used with a broad range of

flux cored wire (Innershield and Outershield) elec-

trodes and solid wires for MIG welding (gas metal arc

welding). Welding can be finely tuned using the “ARC

CONTROL”. Turning the ARC CONTROL clockwise

from -10(soft) to +10(crisp) changes the arc from soft

and washed-in to crisp and narrow. It acts as an

inductance/pinch control. The proper setting depends

on the procedure and operator preference. Start with

the knob set at 0.

For any electrodes, including the above recommenda-

tions, the procedures should be kept within the rating

of the machine. For additional electrode information,

See www.lincolnelectric.com or the appropriate

Lincoln publication.

ARC GOUGING

For optimal performance when arc gouging, set the

VANTAGE 500 CUMMINS “WELD MODE” switch to

the “CC - STICK” position, and the “ARC CONTROL”

to 10.

Set the “OUTPUT” knob to adjust output current to the

desired level for the gouging electrode being used

according to the ratings in the following table:

NOTE: If desired the CV mode can be used for Arc

Gouging.

* Maximum current setting is limited to the VANTAGE

500 CUMMINS maximum of 575 Amps.

PARALLELING

When paralleling machines in order to combine their

outputs, all units must be operated in the CC-STICK

mode only at the same output settings. To achieve

this, turn the WELD MODE switch to the CC-STICK

position. Operation in other modes may produce errat-

ic outputs, and large output imbalances between the

units.

AUXILIARY POWER OPERATION

If a GFCI receptacle is tripped, See the MAINTE-

NANCE section for detailed information on testing and

resetting the GFCI receptacle.

Start the engine and set the IDLER control switch to

the desired operating mode. Full power is available

regardless of the welding control settings, if no weld-

ing current is being drawn.

The auxiliary power of the VANTAGE 500 CUMMINS

consists of two 20 Amp-120VAC single phase (5-20R)

GFCI duplex receptacles, one 50 Amp-120/240VAC

single phase (14-50R) receptacle and one 50 Amp

240VAC three phase (15-50R) receptacle. The

120/240VAC receptacle can be split for single phase

120 VAC operation.

The auxiliary power capacity is 12,000 watts of 60 Hz,

single phase power or 20,000 watts of 60Hz, three

phase power. The auxiliary power capacity rating in

watts is equivalent to volt-amperes at unity power fac-

tor. The maximum permissible current of the 240 VAC

output is 50 A. The 240 VAC single phase output can

be split to provide two separate 120 VAC outputs with

a maximum permissible current of 50 A per output to

two separate 120 VAC branch circuits. Output voltage

is within ± 10% at all loads up to rated capacity.

NOTE: The two 120V GFCI receptacles and the two

120V circuits of the 120/240V receptacle are connect-

ed to different phases and cannot

be paralleled.

The auxiliary power receptacles should only be used

with three wire grounded type plugs or approved dou-

ble insulated tools with two wire plugs.

The current rating of any plug used with the system

must be at least equal to the current capacity of the

associated receptacle.

SIMULTANEOUS WELDING AND AUXIL-

IARY POWER LOADS

It must be noted that the above auxiliary power ratings

are with no welding load.

Simultaneous welding and power loads are specified

in table B.4. The permissible currents shown assume

that current is being drawn from either the 120 VAC or

240 VAC supply (not both at the same time).
