Operating Manual

3. Brief description
Its operating priciple is characterized by the following:
Compressed air serving as plasma gas and cooling medium
for the plasma torch
A high-grade filter welding regulator together with a downstream micro filter are standard
equipment on this unit.
The finely filtered, pressure-controlled air expands in the plasma torch body and serves,
for one thing, as plasma gas and, for another, as a cooling medium for the torch body to
protect against high thermic load.
HF-ignited pilot arc.
A pilot arc which is initiated by a high-frequency spark starter
ensures reliable ignition of the cutting arc even on lacquered workpieces. In addition, this
appliance is suited for automatic cutting processes.
Automatic cutting process
via control board
.
Safety cut-out.
In the event of a pilot-arc failure, the current source switches off after
approx. 2 seconds to protect the operator from a build-up of no-load voltage.
Service friendly design.
All components are easy to change.
