5. Adjust the Start Control Parameters (Optional)

The start control parameters can be adjusted to define how the welding machine will respond when the arc is struck.

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

Open circuit voltage: Sets the power source output voltage for the torch idle condition (the welding machine is on, but not welding).

Strike peak amps: Adjust this parameter to set the peak level for the arc-strike current spike.

Strike peak time: Adjust this parameter to set the duration of peak current for the arc-strike current spike.

Starting volts: Adjust this parameter to set the gun voltage to be maintained during the arc starting routine.

Starting time: Adjust this parameter to set the duration of the arc starting routine.

Starting amps: Adjust this parameter to set the average current level during starting.
