HiFocus 80i

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 0.5mm to 18(25)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.

Based on the approved Soft-Switch-Inverter technology the HiFocus 80i with the microprocessor controlled power source is now at disposal for a cutting range up to 80A at 100 % duty cycle. In connection with the powerful Plasma Torch PerCut 80, quality cutting in a wide range is granted. That means laserlike quality cuts with nearly no dross adherence, lowest straightness tolerances and very clean cutting surfaces.

The high performance capacity of the plasma torch PerCut 80 ensures, in connection with the heavy duty XL-Life-Time system and its longevity of cathodes and nozzles, lowest costs on consumables and minimized downtimes. The technical conditions for the high productivity of the plasma cutting process are optimized operational parts of the beam generation system interacting with microprocessor controlled sequences.

This unique plasma cutting system with HiFocus^PLUS technology will be offered in this performance class for oxygen, nitrogen and air as plasma gases.

Because of the outstanding price-performance ratio, especially the medium sized industry can now become competetive on high-class cutting quality terms.
