3. With the torch in starting position, press and
hold the Torch Trigger. After an initial two sec-
ond pre-flow, the pilot arc will come on and
remain on until the cutting arc starts.
4. Once on, the cutting arc remains on as long as
the Torch Trigger is held down, unless the torch
is withdrawn from the work or torch motion is
too slow.
5. To shut off the torch simply release the Torch
Trigger. When the trigger is released a gas post-
flow will occur. If the Torch Trigger is pushed
during the post-flow, the cutting arc will restart
immediately when the torch is brought within
range of the workpiece.
