Standard 4T process :
Dstart
In 4T mode, the duration of pre gas and post gas is determined with the trigger.
Crater filler and Hot start phases may be added in 2T and/or in 4T mode.
Pulsed 2T process :
T hotstart
Dstart
Soft-start
When pressing the trigger, the pre gas starts, when the wire comes into contact with the welded piece a pulse starts the arc. Then, the machine starts
with a Hot-start, the upslope and the welding cycle starts. When releasing the trigger, the downslope starts until Iblackout. At this moment, the wire
is cut followed by postgas. As in « standard mode », it is possible to quickly resume welding during post gas. Wait for the end of post gas to change
the settings.
