OPERATION

B-7

The VANTAGE® 500 DEUTZ and any high frequency
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 DEUTZ 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 DEUTZ 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.

When used with argon gas. The current ranges shown must be reduced when using argon/helium or pure helium shielding gases.

(2)

Tungsten electrodes are classified as follows by the American Welding Society (AWS):

Pure EWP
1% Thoriated

EWTh-1

2% Thoriated

EWTh-2

Though not yet recognized by the AWS, Ceriated Tungsten is now widely accepted as a substitute for 2% Thoriated Tungsten in AC
and DC applications.

DCEP is not commonly used in these sizes.

TIG torch nozzles are typically made from alumina ceramic. Special applications may require lava nozzles, which are less prone to

breakage, but cannot withstand high temperatures and high duty cycles.
