4.1 Power Factor Correction (PFC)
PFC provides a input power conditioner
system to smooth the input current.
On a conventional inverter machine the input
current presents in short high current pulses
every half mains cycle. These pulses, cause
input voltage drop, on extension leads and
generators.
The PFC spreads the current pulse over the
whole mains cycle.
The overall effect is PFC provides stable
operation, on challenging power supplies,
particularly on long supply leads and
generators.
Power Factor Correction
4.2 Pilot Arc
To create the Plasma gas an arc needs
to be established in the gas flow. A
common starting method was to use high
frequency and high voltage between the
internal electrode and the torch tip. The
high frequency signal can create electrical
interference and disrupt communication,
radio, TV and other electronic equipment.
To overcome this problem the Cutmatic 45
uses a contact pilot ARC method.
Air pressure is used to move the internal
electrode in the torch when the trigger is
pressed. The movement creates a gap which
creates a spark which ignites the plasma
inside the torch head.
When the torch is brought close to the work
piece the , plasma will transfer to the work
piece the current will increase and cutting
can commence.
