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:

ELECTRODE	CURRENT RANGE
DIAMETER	(DC, electrode positive)
(1/8”)	30-60 Amps
(5/32”)	90-150 Amps
(3/16”)	200-250 Amps
(1/4”)	300-400 Amps
(5/16”)	350-450 Amps
(3/8”)	450-575 Amps*

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).
