VR 4040 unreeling device
The VR 4040 unreeling device is a further
member of the modular family of Fronius
wire-feeding equipment.
Suitable adapters are available for moun -
ting whatever wirefeeder unit is used. There
are also suitable adapter sets for fitting a
wide range of different types of wire spool.
In designing the unreeling device, Fronius
paid particular attention to ergonomic issu -
es. Special emphasis was placed here on
making it easier to change the wire spools,
which can often be very heavy. A remova -
ble wire-spool carrier facilitates spool
changeover. If a second wire-spool carrier
is mounted, this can save even more down-
time by making it easy to prepare a second
spool ready for insertion.
The swing-out ramp and the guide-rails make it possible to change the wire spool easily,
quickly and with a minimum of physical effort. The large viewing panel allows users to
check constantly on the operational status, and on how much wire there is left on the spool
(N.B. this latter point can also be monitored by the optional end-of-wire watchdog).
In order to provide greater flexibility at the welding location, the unreeling device comes
with an integral trolley consisting of two fixed castors and two swivel castors. The swivel
castors can be locked, both in the steering direction and in the direction of travel. If one
side of the unreeling-device housing needs to be placed flush against a wall or an adjacent
machine, the VR 4040 can also be ordered in a “mirror-image” version.
The optional end-of-wire watchdog alerts the operator in good time to the fact that the wire
spool will soon need changing. This makes it possible to prevent unnecessary disruption
of the production process. If the unreeling device is used in locations with strong tempera -
ture fluctuations and high atmospheric humidity, we advise ordering the optional interior
heating system. The interior heating system practically rules out any risk of condensation
inside the unit, and so prevents any quality-impairing oxidation from taking place on the
welding wire.
Areas of applica -
tion and features
The VR 4040 unreeling device is specially designed for robot and automated applications.
Both in MIG/MAG welding and in TIG (and laser) cold-wire welding, the VR 4040 unreeling
device is a vital component of any precision, high-performance wirefeed system.
The unreeling device is ideal for wire spools with a mass of up to 80 kg, a diameter of up
to 500 mm and a width of up 250 mm. Increases in the permissible spool mass are possible
on request.
The high-dynamism concept underlying the VR 4040 unreeling device makes possible
both high wirefeed speeds and high wire-spool weights, at the same time as ensuring that
the welding wire is only exposed to a minimum of tensile strain. Even when welding starts
