➤ Quality

This cutting tool is used to obtain the following:

- dimensional and geometrical accuracy of the pieces cut on a wide range of materials,

- quality of the state of the surface of the cut faces(roughness far below that of a laser),

- a low amount of deposits (range 2 to 4 in accordance withISO 9013),

- holes with a remarkable straightness on carbon steel withHOLE MASTER,

- cuts with no adhering slag.

- quality maintained thanks to the optimised life span andwear compensation function CDHC of plasma components.

➤ Productivity

- possibility of adjusting the electrical power in relation to thedesired speed for each thickness,

- possibility of combining several NERTAJET HPi plasmainstallations,

- possibility of combining several speed ranges on the samegeometry with the HPC DIGITAL PROCESS control,

- possibility of combining cutting and marking operations,

- possibility of automatically managing the adjustment ofcutting parameters,

- possibility of using the CYCLE BOOST and INSTANTMARKING functions, thereby reducing the marking andcutting time.

➤ Operating costs

With NERTAJET HPi systems, everything contributes toobtaining an economical cutting price:

- extended life span for wear parts,

- low gas consumption unlike a laser,

- high cutting speed associated with the advanced CYCLE BOOST and INSTANT MARKING functions,

- cutting with several NERTAJET HPi plasma systems(e.g. dual torch).

NERTAJET HPi is the evolution of the traditional plasmaprocess representing the alternative to laser cutting:

NERTAJET HPi comes with various power values:150 A, 300 A, 450 A and 600 A

The power combinations are obtained by using one or several HP150 and HP300HIGH PLASMA power sources.

For each power value, the size FRIOJET cooling unit is specifically designed toobtain the optimum cooling of the torch and offer a 100% duty factor.

The power sources and cooling unit are separated to make maintenance work easier and namely filling upFRIOJET with the heat-transfer liquid FREEZCOOLGREEN -5 °C or RED -35 °C

NERTAJET power sources have been acclaimed for theirreliability and performance for over 40 years.

➤ Wide operating range: from 1 to 90 mm.

➤ Cut with reduced angles.

➤ Protection of cut faces for greater weldability.

➤ The cutting area affected from a thermal point of view and deformationof the pieces is considerable reduced.

➤ The cost for use on stainless steel or aluminium is extremelycompetitive: good cutting speed, cost of fluids, life span of wear parts,even very powerful ones...

Air Liquide Welding constantly offers its clients the best plasma cutting technology. After identifying that cutting holes with a small diameter is a major issue in a number of operating sectors, Air Liquide Welding responded to these expectations with theHOLE MASTER technology.

Based on the latest-generation NERTAJET HPi plasma system and an efficientmanagement of parameters, the HOLE MASTER technology lets you achieve higherquality levels in terms of making holes in black and low-alloy steels where thediameter/thickness of the sheet metal is close to 1.

TWIN DETECT function

There are two sheet metal detection cycles on NERTAJET HPi:

➤ A cycle with acquisition via an electric contact of the sheet metal withthe end of the torch's nose-piece: precision, repeatability and productivity.

➤ A cycle with detection via a pilot arch with argon gas: suitable for alldifficult supports (plastic film, paper labels, thick oxide layer, etc.).The torch looks for the sheet metal with its blown pilot arch.The power of the arch breaks the isolating layer without applying amechanical constraint on the sheet metal and transferring the cut.

The operator can switch from one mode to the other by just switching the HPC's button and thereby quickly adapt to the operating support.

Without CDHC

The torch moves town.The cutting angle and state of the

surface are affected over thecourse of production.

With CDHC

The cutting height remainsconstant. The cutting quality is

It is very important to keep the torch at the same height (arc length) to have anoptimum cutting quality. Conventional height-adjustment systems operate wellwhen wear parts are new, but become less efficient they become worn out: the torch moves closer as the cuts are performed on the sheet metal.

On NERTAJET HPi, thanks to the CDHC function, there is a constant cutting height, regardless of the wear of wear parts. This extends the cutting quality of the pieces across production.

There are a number of plasma marking steps for the purposes of identification ortracking in the thermal cutting industry. Air Liquide Welding provides an innovationwith the instant tipping function of the INSTANT MARKING process.

INSTANT MARKING is used to save time on:

➤ Bleeding time: it is performed instantly during thetransit from one process to the other (Marking/Cuttingor Cutting/Marking).

➤ The tool path: the cutting and marking steps arecarried out subsequently on each piece with nosuperfluous back and forth movement, therebyreducing wear on the machine's drive system.

➤ Unloading pieces: as the marking and cutting arecarried on subsequently for each piece, this meansthey can be unloaded without waiting for the end ofthe nesting process.

INSTANT MARKING also provides the chance to automatically change the marking quality in relation to the kind of layout to create:

➤ Accurate and deep marking to identify the pieces.

➤ Quick and fine marking for the traces (folding steps for instance...)

INSTANT MARKING function

The transitional stages between several plasma cuts are critical for cycle time.

With CYCLE BOOST, NERTAJET HPi considerably reduces production time by acting on:

➤ The tool-holder speed 15 m/min: it allows for almost instant positioning and clearing in relation to the sheet metal.

➤ The tool-holder withdrawal height: in relation to the trajectory in-between cuts, the tool positions itself at different heights. In a low position between 2 cuts one afterthe other or in a high position for greater shifts or the torch might risk reaching anobstacle (a tilted piece for instance).

➤ Saving the sheet metal position: over a series of several cuts one after the other,during the first piecing, the torch detects and saves the position of the sheet metal. The following strikings are performed almost on the fly without a new acquisitionphase.

➤ The gas bleeding time: it is performed in advance during the quick shift of themachine. Therefore, there is no waiting time when the machine reaches the strikingpoint.

Thanks to the combinedeffect of CYCLE BOOSTand INSTANT MARKING,the gain in productivity isestimated to be 30%.

With INSTANT MARKING,the shift of the machine isreduced by nearly 20%.

Life span of soft steel:

The lifespan of plasma wear parts on soft steel is optimised onNERTAJET HPi systems, namely thanks to:

➤ The quality and control on manufacturing of wear parts.

➤ The management of the plasma cycle that perfectlysynchronises the gas, current and position of the torch.

➤ The refrigerated system of the FRIOJET cooling system.

Little wear of wear parts helps reduce your production costsas well as your environmental impact.
