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.
