Stand-O Cung
The stand-o cung technique is the process of holding the p of the torch
between 3-4mm from the workpiece to achieve the opmum cut.
Stand-o cung requires a cung p that you need to ensure that the plasma
machines output amperage is matched to the amperage with the p.
Depending on the applicaon the operator may choose to hold the torch ‘free
hand’ away from the plate or could choose to use a stand-o guide to help hold the
torch away from the plate at a xed height, also available are roller guides and
circle cung guide kits which can be very helpful in creang the cuts you want.
To begin cung you would place the torch above the work piece of about 3-4mm,
and begin drawing the p across the workpiece.
You should always start with the torch placed at farthest point from you and then
cut by pulling the torch towards you.
Make sure to keep the torch upright to the material being cut throughout the
cung process.
As you are cung ensure you maintain a smooth and consistent travel speed to
make a clean and precise cut.
There are 3 main reasons why plasma machine operators prefer to use the stand-o
technique rather than drag p cung
 It allows for a smoother movement of the torch above the material being cut
without any part of the torch touching the material.
 You can comfortably stand the torch while making the contouring process or
following a certain paern.
 Because the cung p is not touching the material, this helps to prevent any
blowback of molten material.
