TORCH PART CONFIGURATIONS

Different hand held torch configurations are available depending
on the cutting or gouging application.
Standard Cutting Setup:
In the Standard Cutting configuration the nozzle is designed not to
touch the work piece. The advantage of this cutting method is
good visibility of the arc. However it requires a steady hand to
avoid touching the nozzle to the work piece which will cause
premature nozzle wear and a jagged cut. An optional drag spacer
can be attached to the retaining cap to maintain a consistent arc
height.

Contact Cutting Setup:
Contact Cutting uses special expendable parts that allow the torch
to touch the work piece. The advantage of contact cutting is that
the torch can touch the work piece, steadily dragging it across the
surface. The disadvantage of contact cutting is the plasma arc is
not as visible as with a standard torch set-up.
There are two types of contact cutting:
1. Direct contact. A special non-insulated nozzle is used that can
touch the work piece directly. This set up is designed for appli-
cations below 40 amps.
2. Shielded contact. A special insulated nozzle is used in
conjunction with a special drag shield. Shielded contact set-
ups are for applications greater than 40 amps.
