4.2 Options
4.2.1 80A torch for RTC 100 and RTC 150
Optional 60A torches enabling cutting of light gauge sheet metal with a smaller
nozzle are also available for the
RTC 100 and RTC 150 units. From the coding of
the torch, the equipment can tell that an 80A torch has been connected. The
cutting current is automatically limited to 60A. The inside scale then applies to the
cutting current settings.
The permitted equipment duty cycle is based under this combination on the
maximum duty cycle of the 80A torch (see Section 4.3).
4.2.2 Automatic torch
Appropriate automatic torches can be employed for automated operations, e.g.
on cutting machines. The specification details will be found in Section 4.3.
When an automatic torch is used, a mechanised interlock may be necessary.
Please contact your supplier for further information about this.
4.2.3 Torch accessories
Details of accessories for the various types of torch will be found in Section 4.3.
4.2.4 Air filter attachment
If the REHM BARRACUDA cutting equipment is used in an environment in which
the air is heavily polluted, then use of an air filter attachment is recommended.
This consists of a protective frame and a filter unit which is very easy to replace
when heavily clogged. The air filter attachment can be retrofitted without difficulty.
4.2.5 Mechanised interlock
For automated use of the
BARRACUDA equipment
, an interface can be provided,
the signals of which are metallically separated.
Outputs: - Current-
flowing message (CFL) for message “Cutting arc on”
- Group alarm
- Arc voltage (U) (e.g. for arc voltage height control)
