Start
Using 2--stroke, any gas pre--flow starts when the torch trigger is pressed in (1).
Welding data then rises to the set values or any pre--set Hot start values. When the
torch trigger is released (2), any crater fill is started. After this the values for welding
data return to zero and any gas post--flow completes the welding sequence.
TIP!
If the torch trigger is pressed in again during crater fill, you can extend the
welding by the crater fill’s final data at any time (the dashed line). The crater fill can
also be interrupted when the torch trigger is quickly pressed in and then released
during the crater fill.

Start
During 4--stroke, gas pre--flow starts when the torch trigger is pressed in (1). When
the torch trigger is released (2), welding data goes up to the pre--set values. When
the torch trigger is pressed in again (3) any crater filling is started. After this the
values for welding data go down to stop data.
Any gas post--flow starts when the torch trigger is released (4).
TIP!
The crater fill stops when the torch trigger is released (4). If the contact is
instead pressed in for a longer time, welding continues with the crater fill’s final data
(the dashed line).
