3. 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 time: Adjust this parameter to set the duration of peak current for the
Strike Peak I & Strike I: Adjust these parameters to set the peak current level for the
The Strike Peak I is set to some level (e.g. 50 amps) higher than the Strike I to improve current step responsiveness. In other words, the actual current has a tendency of lagging behind in rapid stepping of commanded current. A higher initial Strike Peak I is designed to overcome this problem.
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.
