VANTAGE® 300 settings when using the K930-2 TIG Module with an Amptrol or Arc Start Switch:

•Set the MODE Switch to the TOUCH START TIG setting.

•Set the "IDLER" Switch to the "AUTO" position.

•Set the "WELDING TERMINALS" switch to the "REMOTELY CONTROLLED" position. This will keep the "Solid State" contactor open and provide a "cold" electrode until the Amptrol or Arc Start Switch is pressed.

When using the TIG Module, the OUTPUT CONTROL on the VANTAGE® 300 is used to set the maximum range of the CUR- RENT CONTROL on the TIG Module or an Amptrol if connect- ed to the TIG Module.

WIRE WELDING-CV

Connect a wire feeder to the VANTAGE® 300 according to the instructions in INSTALLATION INSTRUCTIONS Section.

The VANTAGE® 300 in the CV-WIRE mode, permits it to be used with a broad range of flux cored wire (Innershield and Outershield) electrodes 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 prefer- ence. Start with the dial set at 0.

NOTE: In the CV-Mode with VRD “On”, the OCV(Open Circuit Voltage) is not reduced. For indicator light operation, see table B.1.

ARC GOUGING

The VANTAGE 300 can be used for arc gouging. For optimal performance, set the MODE switch to ARC GOUGING.

Set the OUTPUT CONTROL knob to adjust output current to the desired level for the gouging electrode being used accord- ing to the ratings in the following Table B.4.

	TAbLE b.4
Carbon Diameter	Current Range (DC, electrode
	positive)
1/8"	60-90 Amps
5/32"	90-150 Amps
3/16"	200-250 Amps
1/4"	300-MAX Amps

The ARC CONTROL is not active in the ARC GOUG- ING Mode. The ARC CONTROL is automatically set to maximum when the ARC GOUGING mode is selected which provides the best ARC GOUGING per- formance.

NOTE: With the VRD switch in the “ON” position there is no output in the Arc Gouging Mode. For indicator light operation, see Table B.1.

AUXILIARY POWER:

Start the engine and set the IDLER control switch to the desired operating mode. Full power is available regardless of the welding control settings providing no welding current is being drawn.

Simultaneous Welding and Auxiliary Power Loads The auxiliary power ratings are with no welding load. Simultaneous welding and power loads are specified in the following table. 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).
