3 SYSTEM PRESENTATION
3.1 General
Saber 70 chp is a user-friendly, compact generator for plasma
cutting.
Saber 70 chp uses compressed air as its only gas source, which
can be supplied from a normal compressor or from a suitably
sized centralized plant. It is able to carry out, cheaply, cuts of a
high quality up to a thickness of 25 mm in carbon steel, while
still keeping its weight and size very limited.
The Saber 70 chp is equipped with an automatic circuit for the
reignition of the pilot arc, that allows metal grill structures to be
cut in the best way.
There are safety systems that cut off the power circuit when the
operator comes into contact with live parts of the machine, as
well as controls to reduce the wear on the electrode and nozzle
at the moment of striking the cutting arc.
The ignition of the pilot arc takes place without the use of high
frequency, with an increase in the working life of the parts of the
torch subject to wear, and reduction in the mains interference.
