10 Service Information
The electrical components of the equipment
are shown in the circuit diagram on page 14.
The Plasma Cutter is an inverter type design,
where the mains supply is first rectified,
filtered then chopped to a high frequency
before being applied to the AC weld
transformer. The output of this transformer
is rectified to form the welding output of the
machine.
If the supply cable is damaged it must
be replaced by the manufacturer, their
service agent or a similarly qualified
person.
