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

When using the TIG Module, the OUTPUT CONTROL on the VANTAGE® 400 is used to set the maximum range of the CURRENT CONTROL on the TIG Module or an Amptrol if connected to the TIG Module.

NOTE: The TIG process is to receive a low voltage welding process. There is no difference in operation with the VRD “On” or “Off” for this mode. For indicator light operation, see Table B.1.

WIRE WELDING-CV

Connect a wire feeder to the VANTAGE® 400 according to the instructions in INSTALLATION INSTRUCTIONS Section.

The VANTAGE® 400 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 preference. 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.

TABLE B.5

ARC GOUGING

The VANTAGE® 400 can be used for arc gouging. For opti- mal performance, set the MODE switch to CC-STICK and the ARC CONTROL to +10.

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