The pilot arc starts immediately when trigger is pressed.
For shielded cutting, place drag shield on edge of metal. For
Adjust torch speed so sparks go thru metal and out bottom of cut.

trigger. Pilot arc starts.
Pause briefly at end of cut before releasing trigger.
After cutting arc starts, slowly start moving torch across metal.
Postflow continues for approx. 12 seconds after releasing trigger; cutting arc can be in- stantly restarted during postflow by raising trigger lock and pressing trigger.
As a convenience, the torch can be set up with two cutting combinations, either drag or
.Maximum performance on thicker materials can be obtained by using
Drag Cutting
Use retaining cup (197 567) and drag shield (196 929) to obtain a 1/16 in (1.6 mm) standoff automatically. This combination is designed to allow dragging the torch directly on the workpiece.
Use shields for ease of use when cutting with a template, or when drag cutting is preferred.

. This combination can be used for drag cutting but does not provide optimum cutting performance on thicker material.
