The VANTAGE 500 CUMMINS and any high frequen- cy generating equipment must be properly grounded. See the K930-2 TIG Module operating manuals for complete instructions on installation, operation, and maintenance.

When using the TIG Module, the OUTPUT control on the VANTAGE 500 CUMMINS is used to set the maxi- mum range of the CURRENT CONTROL on the TIG Module or an Amptrol if connected to the TIG Module.

VANTAGE 500 CUMMINS SETTINGS WHEN USING THE K930-2 TIG MODULE

•Set the WELD MODE switch to the “Touch Start Tig 20-250 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” elec- trode until the triggering device (Amptrol or Arc Start Switch) is pressed.
