OPERATION
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.
Operation continued
Normal cutting mode
Normal cutting
-
this mode is the most commonly used for edge start or pierce cutting.
When edge cutting, hold the torch perpendicular to the edge of the material being cut with the
cutting tip near (but not touching) the edge of the workpiece at the point where the cut is to start.
Press and hold the trigger and once the pilot arc has initiated, slowly move the torch over the material
until the cutting arc is established then
‘
cutting
’
movement can commence. Generally the direction of
cutting is towards the user.
To stop cutting just release the torch trigger.
However if the plasma torch is either pulled away from the material or you come to the end of the
material being cut and you run off the plate the plasma cutting arc will automatically stop. To re
-
initiate
the plasma arc you would have to release the torch trigger to repress the trigger, so in the case of cutting
grid or perforated material we have the following option that should be used.
Perforated cutting mode (Mesh cutting)
Perforated cutting
-
This setting is ideal if you are cutting mesh, grid or perforated type material
(as image 1 shows below) where you have gaps between the material being cut.
When cutting in
‘
normal
’
mode the plasma arc will automatically
‘
cut out
’
if it can
’
t find metal to complete
the electric circuit, so switching the machine to perforated cutting mode will keep the plasma arc ON
otherwise, you will have to keep releasing/pressing the trigger to restart the plasma arc over and over.
When in perforated cutting mode and when cutting in the travel direction as shown in image 2 below,
the torch plasma arc circuit will switch between piloting mode and cutting mode automatically,
depending if your torch is above the material or not.
Image 1
below shows an example of material which when cutting would be used in the
‘
mesh/perforated
’
setting mode.
Image 2
below helps to explain how the machine can cut perforated/mesh material and automatically
switches between pilot and cutting mode without the operator having to release and then re
-
press the
torch trigger multiple times.
