2. Application
ERGO-STW-R welding station has been developed for extraction the dust laden air from the
workplace –from above the welding table –and cleaning it from dry dusts (without aggressive
impurities or without compounds creating explosive conditions) and capturing fumes arising
during grinding, welding etc.
The welding station is appropriate for application during machining of small constructional ele-
ments in lock smith workshops. The extraction takes place upwards through the extraction
arm and downwards through the suction chamber (with a grate in top surface).
Necessarily, the device ought to be connected to the ventilation system to discharge the pol-
luted air outside the building. The maximum temperature of the conveyed air is 60C.
3. Reservations of Producer
Manufacturer accepts no liability for any consequences following from the operational use that
is in contradiction to the purpose of application.
A.
Installing of any additional elements not belonging to the normal device structure (or acces-
cessory set) is not acceptable.
B.
Any structural changes or modification of the welding station carried out by User on one’s
own are not permitted.
C.
Protect the housing from mechanical damage.
D.
The appliance should not be applied for conveying the air containing:
●
viscous compounds that would deposit on the device structure,
●
aggressive compounds,
●
substances creating explosive conditions.

5. Structure and Function
ERGO-STW-R welding station consists of:
●
radial fan,
●
ERGO extraction arm with a hood (option),
●

●
motor protective switch,
●
worktable with a rotary table,
●
tool locker,
●

The main supporting structure is a workshop table equipped with a rotary table for welding the
small elements and a suction chamber with a grate. Under the table is placed an extraction fan
which (according to the damper position) is extracting the impurities UPWARDS through the ex-
traction arm or DOWNWARDS through the grate in the tabletop.
Whereby the mechanical impurities are falling into the waste drawer which ought to be emptied
systematically.

The extraction fan ought to be connected to the ventilation system to discharge the polluted
air outside the process room. Whereas, in the lower part of the device is located a grounding
clamp which has to be connected with the mass cable of the welding machine.
To start the extraction fan, simply, press the pushbutton in the motor protective switch.
6. Assembly and Start-up
The device is designed for operation in closed rooms (indoor application). Simply, it should
be placed stably on an even floor surface, so there is free access of the cooling air access
to the motor and, on the other hand, the control unit and waste-container are accessible for
the operator.
CONNECTION TO THE POWER SUPPLY SYSTEM
Connection to the power supply system ought to be carried out by a person with qualifica-
tions and according to the valid regulations. Prior to connection make sure if the parame-
ters of the existing installation are corresponding with the data on the nominal plate. Prior
to start-up check the connection between the motor and the PE protective cable
and examine the correctness of electrical connections, among others: the impeller rotation
sense should be according to the arrow on the housing. In case of opposite direction, turn
the phase converter inside the plug.
Connection of the fan to the power supply is illustrated in Fig. No.2.
BEFORE THE OPERATION:
1.
Set the hood inlet in a suitable position: not more than 30 cm from the welding arc, and
not less than 20 cm –as the welding chippings (spatters) could damage the hood surface
and the suction stream could interrupt the gas coating (CO2, argon).
2.
Adjust the intake air volume with the shut-off damper lever to control the dust and fume
extraction most efficiently.
3.
The position of the hood of the extraction arm and the shut-off damper lever can be chan-
ged many times during the work, so operator can adjust them best to the current needs.
AFTER THE WORK IS COMPLETED:
1.
Turn off the device with the red pushbutton.
2.
Leave the extraction arm in the ultimately used position (operational state), or if this cau-
ses barrier to the personnel / people in vicinity –set the extraction arm into home position.

7. Operational Use
ADJUSTMENT OF THE ERGO EXTRACTION ARM:
Prior to the operational use, it is important to install the ERGO extraction arm on the work-
table by means of 6 nuts belonging to the mounting pins, and then follow subsequent
steps:
1.
Make sure if the ventilation installation is functioning.
2.
Set the hood inlet in a suitable position appropriate for fume- and dust control and simul-
taneously not causing barrier to operator’s movement and not limiting the field of view at
the workplace.
By turning the shut-off damper lever, adjust the intake air volume most accurate to capture
efficiently the fume and dust. Pay attention, the volume flow cannot be too high, as it could
produce excessive draught.
During the operational use, the position of the hood, extraction arm and the shut-off dam-
per can be changed many times –currently adjusting them to the needs of operator.
Each joint is equipped with a frictional brake to stabilise the extraction arm and keep it in the
the requested position (self-supporting features) during the operational use.
Fig. No.4
The adjustment of the frictional brakes is carried out by increasing or reducing the tension
of the disk-springs upon the frictional elements. To increase the frictional moment tighten up
the nuts, whereas releasing the nuts reduces the pressure tension.
The brake adjustment in the subsequent joints ought to be executed in such a way that ensures
the stability and self-supporting features of the extraction arm (which is important to keep the
stable arm position), whereas, on the other hand this cannot cause any excessive resistance
while User is changing the arm position.

In application of ERGO with a hood with lighting (halogen spotlight with a pushbutton) it is
important to purchase a control unit “TR-ERGO” – transformer 230V, 50Hz / 12V; 50VA along
with protection systems (F1/ 2A and F2/ 3,15A) see Connection diagram of the User’s Ma-
nual “Extraction arms ERGO-M,K,L,D/Z-R”.

9. Maintenance
The device construction guarantees its operational use without the routine everyday technical
supervision. In case when any defective function is visually or by noise noticed, undertake its
technical revision.
Within the range of periodical revisions, every 12 months check the state of the fan according
to the detailed rules of operational use of electrical driving devices.
During the maintenance activity check the mechanical and electrical connections.
Any activity associated with repair / technical revision has to be carried
out exclusively after the device is disconnected from the power supply system.
