1.2.3
Area of application of plasma cutting equipment
BARRACUDA cutting machines are direct-current sources. All conductive metals
can be cut using plasma arc cutting. The maximum material thickness to be cut in
each case depends on the arc power of the current source, the type of material
and the cutting speed used.
1.2.4
Function principle of REHM BARRACUDA cutting
equipment
All
REHM BARRACUDA cutting equipment
is continuously adjustable. This
means that it is possible for the user to quickly adapt it to the specific cutting
tasks. The cutting arc is extremely stable within broad limits thanks to internal
regulation of current. Fluctuations in the power supply are compensated in the
range b6% and -10%.
High performance reserves guarantee the optimum material penetration and
constant cutting performance even under extreme requirements.
With
REHM BARRACUDA cutting equipment
both contact and distant cutting is
possible. In the case of contact cutting, however, the cutting current should not
exceed 50A.
In the development and design of this equipment, the priorities were the best
cutting characteristics, high efficiency, low wear and tear and simple operation
and handling.
All the components were tested extensively under practical conditions for heavy-
duty and industrial usage.
1.2.5
Proper use
REHM plasma cutting equipment is designed to cut all conductive metals. Please
note also any special regulations which may apply to your application. Please
contact your safety officer or REHM Customer Service if you have any queries.
Except where expressly stated otherwise in writing by REHM, REHM plasma
cutting equipment is only intended for sale to commercial or industrial users and
only for use by such users. It must be operated only by people who have been
trained and are qualified in the use and maintenance of plasma cutting
equipment.
Cutting current sources must not be positioned in areas where there is a
significant electrical hazard
see Chapter 5, Commissioning
.
These operating instructions contain rules and guidelines for the proper use of
your equipment. Only use in accordance with these operating instructions will be
deemed to be proper use. Any risks which arise from other forms of use are the
responsibility of the operator. For special requirements, it may be necessary to
observe special additional conditions as well.
Please contact your safety officer or REHM Customer Service if you have any
queries.
Attention should be paid to the specific directions regarding proper use referred to
in the delivery documentation.
Any national regulations which are more stringent than the requirements of these
operating instructions also apply.
