3. With the torch in starting position, press and hold the
Torch Trigger. After an initial two second 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Trigger is held down, unless the torch is withdrawn from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 oc-
cur. 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.
