In standard 4T, the duration of the HotStart and Crater filler is managed by the trigger.
2T Pulse process:
T hotstart
Dstart
Soft-start
When the trigger is pulled, the Pre-gas starts. When the wire touches the part, a pulse initiates the arc. Then the machine starts with the HotStart,
Upslope and eventually the welding cycle starts. When the trigger is released, the Downslope starts to reach ICrater filler. Then the stop peak cuts the
wire followed by the Post gas. As in «Standard», the user has the possibility to quickly restart the welding during the Post gas without going through
the HotStart phase.
