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 prema-
ture nozzle wear and a jagged cut. An optional drag
spacer can be attached to the retaining cap to main-
tain a consistent arc height.
Contact Cutting Setup:
Contact Cutting uses special expendable parts that
allow the torch to touch the work piece. The advan-
tage 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 applications 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.
