B - DESCRIPTION
1 - GENERAL
The OCP torch is a Plasma Cutting Tool that must imperatively be mechanized. It is
designed to be connected connected to NERTAJET HP installations.
In a OCP torch an electrode is inserted with a shape suitable for plasmagene gas, selected
according to the application.
The electrode is fitted on a piston that is incorporated into the torch and controlled
pneumatically.
The mechanical movement created by the piston makes it possible to put the electrode in
contact with the nozzle for a brief instant so as to strike the pilot arc.
The light beam obtained makes it possible to position the torch and detect the plate for
starting the cutting.
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 OCP torches make them universal tools using
the very latest techniques for transferred plasma arc.
The absence of high frequency to start the pilot arc makes it possible
to place with no risk the plasma cutting installation in spots that are
surrounded by electrical and computer equipment.
Its structure consisting of a detachable torch body facilitates:
- maintenance operations,
- replacing expendable parts,
- changes in process.
2 - ELECTRICAL SAFETY
OCP 150
Before any servicing operations on the
torch, make sure that the generator is
powered down.
