OPERATION

B-7

n general the ‘Touch Start’ feature avoids tungsten contamination without the use of a Hi-frequency unit. If the use of a high frequency generator is desired, the K930-2 TIG Module can be used with the Vantage. The settings are for reference.

The Vantage is equipped with the required R.F. bypass circuitry for the connection of high frequency generating equipment.

The Vantage 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 is used to set the maximum range of the CURRENT CONTROL on the TIG Module or an Amptrol if connected to the TIG Module.

VANTAGE 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” electrode until the triggering device (Amptrol or Arc Start Switch) is pressed.

(1)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.

(3)DCEP is not commonly used in these sizes.

(4)TIG torch nozzle “sizes” are in multiples of 1/16ths of an inch:

# 4 =

1/4 in.

6 mm

# 5 =

5/16 in.

8 mm

# 6 =

3/8 in.

10 mm

# 7 =

7/16 in.

11 mm

# 8 =

1/2 in.

12.5 mm

#10 =

5/8 in.

16 mm

(5)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.
