WELDER OPERATION

DUTY CYCLE

Duty Cycle is the percentage of time the load is being applied in a 10 minute period. For example a 60% duty cycle, represents 6 minutes of load and 4 minutes of no load in a 10 minute period.

STICK WELDING MODE

The VANTAGE® 575 CUMMINS 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 over head 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 elec- trode 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.

TOUCH START TIG MODE

The VANTAGE® 575 CUMMINS 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 gen- eral, avoids tungsten contamination. Then, the tung- sten 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 approxi- mately 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® 575 CUMMINS. The settings are for reference.

The VANTAGE® 575 CUMMINS is equipped with the required R.F. bypass circuitry for the connection of high frequency generating equipment.

The VANTAGE® 575 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® 575 CUMMINS is used to set the max- imum range of the CURRENT CONTROL on the TIG Module or an Amptrol if connected to the TIG Module.

VANTAGE® 575 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” electrode until the triggering device (Amptrol or Arc Start Switch) is pressed.
