6. Adjust the Shorting Control Parameters (Optional)

The shorting control parameters can be adjusted to define how the welding machine will respond when the arc shorts to the weld puddle.

To view the shorting control window, click on the button on the Waveform Editor screen. Adjust the shorting control parameters to accommodate your welding application and per the following parameter descriptions.

Short detect voltage: Adjust this parameter to set the detect voltage level that will start the shorting response.

Pinch current rise rate (shorting response): Adjust this parameter to set the current rise rate that will be used to clear a short.

Arc reestablish volts: Adjust this parameter to set the detect voltage level that will end the shorting response.
