5-5. Sequence Of Cutting Operation
After cutting arc starts, slowly
start moving torch across metal.
Adjust torch speed so
sparks go thru metal and
Pause briefly at end of
cut before releasing trigger.
Raise trigger lock and press
trigger. Pilot arc starts.
Postflow continues for approx. 20 seconds
after releasing trigger; cutting arc can be
instantly restarted during postflow by raising
trigger lock and pressing trigger.
The pilot arc starts immediately
when trigger is pressed.
For standard (shielded) cutting, place drag
shield on edge of metal. For non-shielded
cutting, use 1/8 in (3.2 mm) standoff distance
(dragging tip will reduce tip life).
Connect work clamp to a clean, paint-free
location on metal workpiece, as close to
cutting area as possible.

(517 kPa) for cutting.
