Toparc RC-HD2 Mode D'emploi page 28

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.
4T Pulse process :
T hotstart
Dstart
4T
Soft-start
In 4T pulse, the trigger manages the duration of the HotStart. During the shutdown, it allows to manage the Crater filler.
