Cathode

The term cathode is used because of the negative charge of the „non-fusing electrode“ of the plasma torch. Occasionally, it is also called "electrode“.

CNC

The abbreviation CNC stands for "Computerized Numerical Control" and is an electronic method for the regulation and control of machine tools or also guiding systems.

to the top

Control Gas (KG)

This gas is led to the torch head and controls the presence of the protection cap which is situated there. Consequently, the plasma cutting system can only be started if the torch is installed properly.

CONTOUR CUT

CONTOUR CUT is a further development of the HiFocus technology especially for cutting small contours in mild steel. In particular holes with a diameter to thickness ratio of 1:1 are cut with highest quality.
to the top

CONTOUR CUT SPEED

With CONTOR CUT SPEED contours can be cut at similar quality up to 50% faster. Due to the shorter processing time the costs per cutting metre are reduced.
to the top

CUTBUS

A CUTBUS is used for the data transfer of technology parameters from the guiding system to the height control unit.

to the top

Cutting Gas (SG)

The cutting gas is electrically conductive because of the ionization and can create the main arc between cathode and work-piece. The energy of the arc makes the material melt and the flow rate of the cutting gas drives it out of the kerf. In order to achieve optimum cutting results different cutting gases are used according to material type and thickness (for example: ignition gas air with cutting gas oxygen or ignition gas argon with cutting gas argon/hydrogen, argon/hydrogen/nitrogen, argon/nitrogen).

D

 

Dissociation

In chemistry, dissociation is the excited or self-acting process in which chemical compounds separate into two or more molecules, atoms or ions. The dissociation energy is the energy which is required to separate the chemical compound.

Distance Control

Dross

The drop-shaped adherence at the bottom cutting edge is called dross.

Enthalpy

Enthalpy is the amount of thermal energy which is released (exothermic) or consumed (endothermic) during a process which takes place at constant pressure.

F

 

Fiberlaser

Fiber lasers of the XFocus series of Kjellberg are compact systems. They consist of the laser source with optical fiber, an integrated cooling unit, the control unit with technology database, an automatic gas supply, axis with height control and the cutting head with automatic focus.

H

 

Height Control

Height control units have a great influence on the quality of plasma cuts. They guarantee the right distance between the nozzle of the plasma torch and the work-piece and keep it constant.

HiFocus

HiFocus is a cutting technology developed by Kjellberg Finsterwalde which uses a swirl gas to constrict the plasma beam very strongly. An excellent cutting quality can be achieved (laser-like); the cut surfaces are nearly vertical.

to the top

HiFocus F

HiFocus F is a cutting technology suitable for flying cutting start. The pilot arc does not need to be ignited above the material but ignition can take place beyond. After the torch has been moved towards the workpiece and the pilot arc has touched the material, the main arc is formed automatically.

HiFocus neo

HiFocus neo allows high cutting speed and very good cutting quality at low process costs. The user benefits from low gas consumption, robust copper cathodes and an optimised technology that protects the consumables. Plasma cutting becomes thus even more efficient.

HotWire

A variety of indirect plasma cutting (use of an auxiliary anode, for example a welding wire) for cutting interrupted structures or insulating materials.

I

 

Identification Gas (IG)

This gas is the control gas that is returned from the plasma torch. It serves to identify the different torch heads.

to the top

Ignition Gas (ZG)

This gas is used for the ignition of the plasma arc. It's function is to facilitate the ignition process. It can have a positive influence on the lifetime of the cathode.

to the top

Indirect Plasma Cutting

In contrast to direct plasma cutting the arc is not transferred. The nozzle serves as anode instead of the work-piece.

to the top

Ionization

Ionization is the process of removing one or more electrons from an atom or moleule so that the atom or molecule is left as positively charged ion (cation). The reverse process where a positively charged atom or molecule catches an electron is called recombination.

to the top

M

 

Marking Gas (MG)

The gas used for marking with plasma is called marking gas.
to the top

P

 

Pilot Arc

The pilot arc is responsible for the ignition of the main arc. It has low energy and ensures the beginning ionization of the way between the plasma torch and the work-piece. This can have a positive influence on the lifetime of the cathode.

 

Plasma Gas (PG)

All gases or gas mixtures which can be used for creating the plasma beam and carrying out the cutting process are called plasma gases. There are two phases of the plasma arc: the ignition phase and the cutting phase. Consequently, plasma gases can be divided into ignition gases and cutting gases. They can differ in type as well as volume flow.

 

Plasma Gouging

Plasma Gouging is a process for removing material by using a plasma arc.
 

PLUS Technology

The PLUS technology was developed by Kjellberg Finsterwalde in order to make vertical cuts possible. Whereas conventional plasma cutting produces cut surfaces with a slight inclination, this can be avoided with the PLUS technology, thus creating vertical cut surfaces. Choosing the correct cutting direction (outer contours to the right, inner contours to the left) guarantees that the vertical cut surface is always in cutting direction right and thus at the finished product and not at the waste part.

Quality

see Quality Parameters

to the top

Quality Parameters

The quality of cut surfaces when using thermal separation processes is determined by the rectangularity or inclination tolerance and the average surface roughness. Additionally, the groove lag, the initial fusing of the upper edge and the possible dross or drop formation at the bottom edge of the work-piece can be considered. These parameters are stipulated by the standard DIN EN ISO 9013.

S

 

Sealing Gas (SpG)

Sealing gas is a swirl gas with reduced volume flow that is used for underwater plasma cutting during cutting stops. It prevents the water from getting into the torch head while the torch is underwater.

to the top

Smart Focus

Smart Focus is the new, modern plasma cutting series for the CNC-guided plasma cutting – even under challenging conditions. With just a few settings the plasma units Smart Focus 130, 200 and 300 achieve best results in the cutting range from 1 to 80 mm. For cutting mild steel the proven Contour Cut technology is applied with the new plasma torches PerCut 2000 and 4000.
 

Swirl Gas (WG)

This gas covers the plasma beam. It further contributes to improving the cutting quality because it constricts and cools the arc additionally and protects the consumables during piercing and underwater cutting. Here, too, different gases can be used.

X

 

XFocus

The fiber laser of the XFocus series are suitable for marking and cutting mild and stainless steel as well as aluminium up to 15 mm. As addition for cutting of thin sheets the laser systems can be adapted easily to all common, for plasma cutting suitable guiding systems.
