A - SAFETY INSTRUCTIONS
For general safety instructions, please refer to the specific manual supplied with
the equipment.
EQUIPMENT FOR PLASMA CUTTING
Before any servicing operations on the torch, make
sure that the generator is powered down.
During the cutting operation, the tip of the torch may be heated
considerably. Before removal, it is imperative to use protective
equipment.

Freezcool should not be discharged in large
quantities into the natural environment. You should
observe local emission standards concerning
COD().
Before any emission of this product, contact your
local water Authority to inquire about the regulations
applying to your region.
You should inform them of :
- The COD of the Freezcool (741000 mg/kg)
- The quantity in kg to be discharged
TheWater Authoritywill advise you of theapproach to
be followed and in particular:
- The location
- The quantity
- The timing
...for discharging the product.
The COD (Chemical Oxygen Demand) represents the portion of the product requiring oxygen, (e.g.
oxidizable mineral salts and the major part of organic compounds).

B - GENERAL
GENERAL :
Machine PLASMA Cutting (CPM) torches are cutting tools which are necessarily
mechanised and designed to be connected to NERTAJET HP installations.
In a CPM torch an electrode is inserted with a shape suitable for plasmagene gas,
selected according to the application.
The torch-end receives a nozzle which, through the combined effect of the electric
arc and the plasmagene gas, forms plasma.
The resulting high temperatures melt the material which is to be cut (electricity
conductor) and the kinetic action of gas on it effects the cutting kerf.
The numerous possible assemblies on CPM torches make them universal tools
using the very latest techniques for transferred plasma arc.
ELECTRICAL SAFETY :
For your safety and in order to compiy with safety standards, we have fitted, on the
top part of the rack, a connecting point enabling the rack pipe to be grounded.
in practice, this point is linked to the moveable part of the machine which supports
the torch. This point will it self be grounded.
The electric connections must be carried out using wires with a cross section at
least équivalent to that of the largest generator phase wire.
Before any servicing operations on the torch, make sure that the generator is
powered down.
SCALES :
The cutting conditions indicated in the scales will generally produce excellent cuts
without any other modifications.
For some particular cases (special metallurgy compositions, coatings), it may be
necessary to carry out slight modifications in the conditions specified in the scale.
The parameters which will have the most significant effect on the cutting quality
are:
- speed of movement,
- distance between the torch and work-piece to be cut (arc voltage).
The intensity and fluid flowrates are optimised and must not be considered as
variables.
Quite the opposite, modifying these parameters in relation to the recommended
settings will reduce the service-life of the wear-and-tear parts and downgrade the
quality of the cut.
