OPERATION

B-6

The OUTPUT CONTROL dial adjusts the full output range for pipe welding.

The ARC CONTROL dial sets the short circuit current (arc-force) during stick welding to adjust for a soft or more forceful digging arc (crisp). Increasing the number from -10(soft) to +10(crisp) increases the short circuit current which results in a more forceful digging arc.

Typically a forceful digging arc is preferred for root and hot passes. A softer arc is preferred for fill and cap pass- es where weld puddle control and deposition (“stacking” of iron) are key to fast travel speeds. This can also increase spatter.

It is recommended that the ARC CONTROL be set to the minimum number without electrode sticking. Start with the dial set at 0.

NOTE: With the VRD switch in the “ON” position there is no output in the DOWNHILL PIPE mode. For indicator light operation, see table B.1.

TIG WELDING

The TOUCH START TIG setting of the MODE switch is for DC TIG (Tungsten Inert Gas) welding. To initiate a weld, the OUTPUT CONTROL dial is first set to the desired current and the tungsten is touched to the work. During the time the tungsten is touching the work there is very little voltage or current and, in general, no tungsten contamination. Then, the tungsten is gently lifted off the work in a rocking motion, which establishes the arc.

When in the TOUCH START TIG mode and when a Amptrol is connected to the 6-Pin connector the OUT- PUT CONTROL dial is used to set the maximum cur- rent range of the current control of the Amptrol.

The ARC CONTROL is not active in the TIG mode. To STOP a weld, simply pull the TIG torch away from the work.

When the arc voltage reaches approximately 30 Volts the arc will go out and the machine will reset the cur- rent to the Touch Start level.

To reinitiate the arc, retouch the tungsten to the work and lift. Alternatively, the weld can be stopped by releasing the Amptrol or arc start switch.

The VANTAGE® 500 can be used in a wide variety of DC TIG welding applications. In general the ‘Touch Start’ feature allows contamination free starting with- out the use of a Hi-frequency unit. If desired, the K930-2 TIG Module can be used with the VANTAGE® 500 . The settings are for reference.

VANTAGE® 500 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.
