Interface can be connected directly to the external current connectors
to the plasma source, without CNC / Voltage Divider connector Please
note that the PLUS potential is the MATERIAL CLAMP TERMINAL )
and the negative potential ( MINUS ) is fed to the ELECTRODE of the
torch - usually via an air-current connector. There may be high voltage
on the electrode lead during arc ignition and this lead should be double
insulated - one strand of double core cable ( 2 x 0.75mm2 / 400V ) can be
used for this purpose leaving the outer insulation. The wires should be as
short as possible (Interface mounted inside or at the plasma source). Due
to the very high interference and overvoltage generated, it is recommended
to connect the MINUS/ELECTRODE measurement cable before the
HF/HV ioniser coil - this is usually the closest element to the torch
connector.

An optional voltage divider can also be
fitted to equip the cutter with a low-voltage
CNC port.
