Performance features of the TIGER gas shielded
tungsten arc welding unit
The TIGER is a real powerhouse, compact in size and weighing a mere 5,4 kg
(Tiger 170 DC; 8,4 kg for the Tiger 210 AC/DC). The robust housing makes the
TIGER the ideal companion for coping with the arduous working conditions on-
site. However the TIGER is also at home in the workshop as well, having all of
the attributes associated and expected of professional units.
The TIGER is based on the primary inverter design principle. The user has a fully
portable unit and also enjoys the Ingress protection classification of IP23 so it
can be used under difficult operating conditions. The units offer flexibility and are
for the universal use on high and low alloyed steels as well as Aluminium and its
alloys (only for AC/DC units
).
REHM-Design housing
The ergonomic design of the machine is a result of the further development of
the REHM-Design concept. The housing has ingress protection classification
IP23. The plastic housing is formed such that is it completely enclosed, the
turn and set knob has a rubber seal, this enables the machine suitable for
welding outside.
REHM Thermal protection
The Tiger is protected against damage caused by over heating by a thermal
sensor. The position of the sensor is directly next to the power transistors and
measures the temperature directly from within the „Hot Spot“.
REHM All round protection
The power transistors are the heart of any inverter; they are completely potted
and sealed together with the primary rectifier and the thermal protection probe
in a single module. This means that dirt and damp will have no affect on this
module. The outer plastic housing is a composite with fibreglass and ensures
the highest protection against mechanical damage. The turn and set knob is
set into the recess in the housing that also serve to prevent accidental
damage. Should the knob receive direct vertical force then this has no
influence on the electrical components. All of the electrical components are
coated with a protective lacquer to protect them against dirt and dampness.
REHM Automation
Connection to an automatic welding system is extremely easy due to the
precise processor control system.
REHM Inverter Technology
The Rehm inverter technology ensures excellent ignition characteristics, and
a steady, stable arc.
By the use of high quality and performance components, the machine can be
produced in an extremely compact design with a low weight.
REHM Ergonom-System ®
The REHM Ergonom-System enables your Tiger to be your sympathetic
partner for all of your welding applications. Apart from the obvious ergonomic
advantages such as the turn and set control knob - which is ideal for right or
left handed persons, the carrying strap and the clearly arranged, easy to
understand operating panel simplify life for the operator. These are many
small details, which help the operator do his job better.
