5.2 Short description of the main features of the device
The punching device is equipped with a special brake which stops the forward motion of the piston / dies when the trigger is released.
The punching head can be rotated continuously around the longitudinal axis in order to gain better access to tight corners and other difficult working areas.
A white LED lamp illuminates the working area after actuating the trigger and turns off automatically 15 seconds after releasing the trigger. This feature
can be deactivated.
The compact ergonomic shaped housing consists of 2 components. The grip area is particularly slip-free through its rubber coating and together with
the barycentric housing, the hand-held device is comfortable to hold and assists in fatigue-free application.
All functions of the device can be controlled with one control knob, resulting in simple handling and improved support, in comparison to two-button
operation.
Li-Ion batteries do neither have memory nor self-discharge effects, providing the operator even after long breaks, always with an operational device.
In contrast to NiMH batteries, Li-Ion batteries weighs less, have 50% more capacity and shorter recharge times.
The oil used, is a fast biodegradable and non-water-endangering high performance hydraulic oil with the
suitable for very low temperatures and has excellent lubricating properties.
The device is equipped with a microprocessor control which shuts off the motor automatically after completing the punching operation, indicating
service intervals and battery charge status and performs an error-diagnostic.
5.3 Description of the operating functions
A punching operation is triggered by operating the control switch (item 7). The electro-hydraulic punching device type Powerlec Vario is equipped with a
special circuit board which switches the motor off automatically after successful punching process. The control switch (item 7) must be pressed
continuously during the punching process. The device is equipped with a special brake that stops the feed process after the control switch is released.
Through a single press of the retract slide (item 2) the pressure ring returns to its original position.
5.4 Description of the automatic control of the the punching procedure
The Powerlec Vario is equipped with a microprocessor controlling the following procedures:
a.) The punching cycle
After a successful punching process i.e. when the punch has cut the metal, the motor of the unit turns off automatically. This serves as a the safety function
for the operator and protects the punching tools. This safety function prevents that the punch touches the die base with full force, consequently damaging
the punch, or in worst cases break the die apart.
b.) Display when the next service is due
The electro-hydraulic unit is equipped with a controller enabling the user to see when the next service is due by flashing for 20 sec. at the end of a working
cycle (see also heading 5.5). The unit must be returned to häwa GmbH. Failure to observe this request results in loosing the warranty. Preventive mainte-
nance for your safety.
