Filter pressure reducer
The working pressure is set on the pressure reducer which is equipped with an
integrated coarse filter If, despite the availability of adequate supply pressure, the
specified working pressure cannot be reached, heavily clogged filters may be the
cause. In this case, the filter cartridges must be changed.
The water tanks must be emptied regularly by actuating the waste valve.

6. Initial operation
6.1 Installation of the cutting unit
When putting the unit in place, please make sure there is sufficient space for inlet and
outlet cooling air so that the rated duty cycle will be attained.
The unit should neither be exposed to moisture not to the plasma arc or the spark ray
caused by grinding work.
6.2 Mains connection
To be carried out only by a qualified electrician!
Connect mains plug to mains cable as specified on the rating plate. The yellow-green lead
is provided for PE earth conductor. The three phases (black, brown, and blue) may be
connected to L1, L2, and L3 at random.
6.3 Compressed-air connection
Fix the pressure reducer unit at the back of the machine.
Plug the connection hose of the pressure reducer unit into the coupling at the machine.
Machines with the option ”one-gas-torch” the gas will go thru one pressure reducer unit to
the torch.
Machines with the option ”two-gas-torch” the gas will go thru two separate pressure
reducer units to the torch. One for the compressed air and one for the plasmagas.
Connect the compressed air supply at the filter pressure unit.
Take care that there is always an adequate supply of compressed air of the specified
pressure.
Moreover, the air should be free of oil and water.
