HiFocus 161i neo

The exceptional quality on the cutting surfaces, characterised by dross-free cuts, the very small straightness and inclination tolerances as well as the low roughness are in connection with the high precision in the tolerance range and the high part reproducibility in relation with the excellent productivity, are the parameters on which the world-wide reputation of the HiFocus technology is based.

The request for a plasma cutting unit with HiFocus^PLUS technology for materials from 0.5 to 30(50) mm was the reason for this new product development. Additionally the rising demand of the metal forming industry calls for a future-orientated and up-to-date HiFocus system, covering its technical capabilities and meeting all requirements on the local and international market.

The plasma cutting system HiFocus 161i neo with its progressive Soft-Switch Inverter and the latest plasma torches PerCut 201 and PerCut 211 (quick-change torch with bayonet joint) is designed for marking and cutting operations on mild steels, stainless steels, aluminium and other electrically conductive materials in a range of 0.5 to 50mm and offers various new possibilities for the application in the metal-working industries, vehicle fabrication, container production, etc.

With the HiFocus 161i neo the user gets a unit which ensures a steady cutting process even under unfavourable conditions. Foil-coated or soiled material surfaces, inclusions in the metal, air gaps as well as mild steel with enhanced content of silicon or sulphur do not influence the cutting operation.

Tech. specifications

Cutting & Piercing

Plasma cutting of electrically conductive materials with HiFocus quality from 0.5 to 50mm (material depending); recommended range for production from 0.5 to 30mm (technology depending)
HiFocus-speed: high cutting performance in the lower thickness range, because of up to three times higher cutting speed, with sometimes slightly increased cut angle
Plasma torch suitable for marking and punch setting also on coated materials without changing torch parts; plasma gas control unit FlowControl necessary
CNC-controlled cutting with machine torches for plasma gases oxygen, nitrogen or argon / hydrogen mixtures
Fast cutting start because of very short transition time
Low squareness and inclination tolerances of the cutting surface; nearly no rework required
Precise profiles when cutting sharp edges or narrow radii
Cutting of small holes
HiFocus technology grants high part accuracy
No or easy to remove slag adherence
Longevity of torch consumables because of second gas ignition and nozzle saving piercing with swirl-gas technology

Power source HiFocus 160i

Flexible adaptation of the process sequence to the cutting conditions by soft-switch inverter with microprocessor control
Optimum process control due to very fast cutting-current adaptation
Process monitoring for torch cooling, ignition time, pilot arc time, short circuit time at torch ignition, power source, etc.
Indication of operation sequences, fault report by LED and display
Provided with analogue interface for CNC-controls and serial interface as well
Serial data transfer to PC for diagnostic purposes
Stepless cutting-current adjustment from 10 to 160 A for cutting, and 4 to 25 A for marking
Optimum piercing capabilities by stepless time delay for the main arc and adjustable current raise in four steps
Adjustable current reduction at corner-, start- and stop signals from the guiding system
Automatic display of the pre-selected cutting current

Plasma Torch PerCut 201

Plasma cutting torch PerCut 160 with newly developed nozzle-cathode concept and swirl-gas technology ensures absolutely stable main arc properties
Longevity of consumables due to water cooling, swirl gas and dual-gas ignition
Hose parcel extensions enlarge the operational radius up to 55m
Special torches for specific applications available on request (robot types; with short and/or bended shafts).
