3. Brief description
The Plasma CUTTER 150 has been developed in robust technology.
It excells in multipurpose application both for manual cutting operations and in combina-
tion with automatic or robot-operated cutting processes.
Its operating principle 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.
Central socket to connect the plasma torch
The cutting unit is operable with two types of plasma torches: one robust torch, and a
smaller, handy version suited for cutting thin materials.
The central socket ensures a quick change of the torches.
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.
Fault indicator
lights up if the current source is overheated or if there is insufficient supply of compressed
air or if the working pressure has been set too low or if the Flap in the right side panel is
open (only option single gas guide). No starting of the arc via torch trigger possible.
After elimination of the deficiency, the plant will be operable again.
- With the fan running, the unit will be operable again after approx. 5 min.
- Check the compressed air mains supply
- Close the flap in the right side panel
Service friendly design
All components are easy to change.
