Upslope time duration.
t3 ~ t4:
Welding beaning conducted.
t4:
Torch trigger activated. Welding current starts to decrease until crater current reached.
t4 ~ t5:
Downslope time duration.
t5 ~ t6:
Crater current duration.
t6:
Trigger released. Arc goes out, shield gas flows.
t7:
Shield gas valve shuts. Welding ends.
