The plasma-cutting torches of the PSB series are exclusively intended for the
cutting of low- and high-alloy materials using compressed air for industrial or
commercial use by trained operators. These plasma torches are air-cooled
cutting torches.
All elements together form an operating unit which provides a plasma arc for
cutting when supplied with the appropriate operating resources. When cutting,
compressed air is ionized in the cutting nozzle. In PSB 31 KKS and KZS, this is
done by means of short-circuit ignition. The initial arc produces a conductive
plasma which is accelerated in the nozzle and directed to the part. The
working arc is struck between the cutting torch electrode and the part. The
work-piece material is melted by the energy of impact, dissociation and
ionisation and blown out by the kinetic energy of the plasma jet. The
compressed air is used to cool the cable assembly and cutting torch.
DANGER
Risk of injury due to unexpected start-up
The following instructions must be adhered to for the entire duration of
maintenance, servicing, mounting, dismounting and repair work:
• Switch off the power source and close off the gas supply.
• Pull the mains plug.
