WELDER OPERATION

DUTY CYCLE

Duty Cycle is the the ratio of the uninterrupted on-load duration to 10 minutes. The total time period of one complete on-load and no- load cycle is 10 minutes. For example, in the case of a 60% duty cycle, load is applied continuously for 6 minutes followed by a no- load period of 4 minutes.

STICK WELDING MODE

The Vantage can be used with a broad range of DC stick electrodes.

The MODE switch provides two stick welding settings as follows:

CC-STICK MODE

The CC-STICK position of the MODE switch is designed for horizontal, vertical-up and overhead welding with all types of electrodes, especially low hydrogen. The OUTPUT CONTROL knob adjusts the full output range for stick welding.

The ARC CONTROL knob sets the short circuit (arc-force) current during stick welding. Increasing the number from -10 (Soft) to +10 (Crisp) increases the short circuit current and prevents sticking of the electrode to the plate while welding. This can also increase spatter. It is recommended that the ARC CONTROL be set to the minimum number without electrode sticking. Start with the knob set at 0.

DOWNHILL PIPE MODE

This slope controlled setting is intended for “out-of-position” and “down hill” pipe welding where the operator would like to control the current level by changing the arc length. The OUTPUT CONTROL knob adjusts the full output range for pipe welding.

The ARC CONTROL knob sets the short circuit current (arc-force) during stick welding to adjust for a soft or a 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 passes where weld puddle control and deposition (“stacking” of iron) are key to fast travel speeds. It is recommended that the ARC CONTROL be set initially at 0.

TOUCH START TIG MODE

The Vantage can be used in a wide variety of DC TIG welding applications.

The TOUCH START TIG setting of the MODE switch is for DC TIG (Tungsten Inert Gas) welding. To initiate a weld, the OUTPUT CONTROL knob 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, avoids tungsten contamination. Then, the tungsten is gently lifted off the work in a rocking motion, which establishes the arc.

To stop the arc, simply lift the TIG torch away from the work piece. When the arc voltage reaches approximately 30 volts, the arc will go out and the machine will automatically reset to the touch start current level. The tungsten may then be retouched to the work piece to restrike the arc. The arc may also be started and stopped with an Amptrol or Arc Start Switch.

The ARC CONTROL is not active in the TIG mode.

In 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 setting.

•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.
