OPERATION - MODES OF CUTTING
Before starting any welding activity ensure that you have suitable eye protection and
protective clothing. Also take the necessary steps to protect any personnel within the
welding area.
Modes of cutting
The following pages show various ways by using different consumable configurations that allows the
operator to cut material with the plasma torch.
See page 34 for the full consumable selection options for the IPT - 60 plasma torch.
Stand - Off Cutting
The stand - off cutting technique is the process of holding the tip of the torch between 3 ~ 4mm from the
workpiece to achieve the optimum cut.
Stand - off cutting requires a cutting tip that you need to ensure that the plasma machines output
amperage is matched to the amperage with the tip.
Depending on the application, the operator may choose to hold the torch ‘ free hand ’ away from the plate
or could choose to use a stand - off guide to help hold the torch away from the plate at a fixed height.
Also available are roller guides and circle cutting guide kits which can be very helpful in creating the cuts
you want.
To begin cutting you would place the torch above the work piece of about 3~4mm, and begin drawing the
tip across the workpiece.
You should always start with the torch placed at the furthest 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 cutting process.
As you are cutting, 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 - off technique rather
than drag tip cutting

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
pattern.

Because the cutting tip is not touching the material, this helps to prevent any blowback of molten
material.
