is established. The current rises according to the UPSLOPE time and to the IStart current value to the main current
adjusted value Ip. When the torch trigger is released, the current decreases according to the IFinal current value.
After the adjusted DOWNSLOPE time, the arc extinguishes, and the POST GAS time begins.
** 4T - The gas starts to flow according to the PREGAS adjusted time when the torch trigger is pressed. When the
torch trigger is released, the arc automatically establishes. The current rises according to the UPSLOPE time and
to the IStart current value to the main current adjusted value Ip. When the torch trigger is press and release, the
