TWISTING MACHINE MT150 A INSTRUCTIONS BOOK 5
1. MACHINE INFORMATION
1.1. Machine identification
Trademark : NARGESA
Type: Twisting machine
Model: MT150A
2.2. Normal use of the machine
The twisting machine is used to shape cold forge materials. It scrolls bars, it makes spirals out of flat bars,
etc. All drawings that can be made by using a rotary head and a stand point will be able to be carried out
with this machine. It’s only shortcoming is the physical space it occupies and the power of the engine.
A set of standard tooling are provided with the machine, by means of which most of the basic shapes will
be makeable. However the manufacturer may supply the head adjustment bases, for you to make your own
drawings.
1.3. Contraindications for the use of it
Every use out of the ones directed to the cold forge work.
1.4. Noise caused by the machine
In case of this machine noise is almost non existent under a normal working condition.
1.5 Vibrations
Like noise, vibrations could be considered non-existent since it is a fixed machine and the head rotation
speed is low.
1.6 Natural working place of the user
The twisting machine could be used by one opeartive at the time who will be located at a side of it.
1.7. Description of the machine
The machine is equipped with an engine of 0,37 Kw / 0,5 HP and a reducer that transmits rotation to the
head through a Crown and the body. This is the stand where all the different stand points are located.
The twisting machine has got a box to keep all tooling and the stand table made of steel plate welded and
folded.
If an accident occurs by negligence of the operative, for not following the safety rules exposed
on this manual, PRADA NARGESA S.L will not accept any responsibility.
TWISTING MACHINE MT150 A INSTRUCTIONS BOOK 6
1.8. Description of accessories
The basic accessories the machine has, are the coupling for the head of the different shapes.It is provided
with different stand parts, stand point and clamping of materials. In the last part of the manual there is a
series of operations which are explained step by step by means of pictures.
1.9. Description of safety devices
Gear and moveable parts are covered with the exception of the rotary head.
1.10. Basic characteristics of the tooling that can be adjusted to the machine
In case of getting accessories fitted to the machine it is necessary to bear in mind that they need to have
the same clamping so that they can not loose or be sent off.
1.11. Information related to the electrical equipment
The MT150A twisting machine, is equipped with a three-phased motor 230V / 400V 0,37Kw, and an electric
set to be able to be connected to a single phased 230V.
The machine can be connected to two different power:
1. A single-phase 230V connection is 230V phase + neutral
2. A two-phase 230V connection is two phases ie 115V
Conversion will not be possible to connect the machine to a three-phase network as long as the installation
of the machine is not replaced by a three-phase network installation.
IMPORTANT
This must be connected to a power supply with ground wire.
Engine Power 0,37 KW / 0,5 HP
2 phased tension 230 V Single phased
Rotary speed Adjustable 0 to 9 r.p.m.
Twisting máximum capacity 20 mm or 3/4”
Bending máximum capacity 16 mm or 5/8”
Max. Scrolling and bending in flat bar 35x10 mm o 1 1/4”x3/8”
Máx. continued scrolling length 960 mm
Dimensions 2260x630x1120 mm
Weight 260 Kg
TWISTING MACHINE MT150 A INSTRUCTIONS BOOK 7
Triangle shape
For tension 230V
The configuration of the plates located inside the terminal box will always be specified as follows:
We provide the machine with a frequency inverter instructions book, it will be useful in case of failure to
identify it and to report it to technical assistance.
The drive is located inside the cabinet.
Internal parameters of the inverter should not be modified, they must be set at the factory. May only ope-
rate the unit under the supervision and advice of NARGESA’s Technical Assistance.
Changing these parameters by unauthorized personnel other but NARGESA’s, could cause a total sus-
pension of the established warranty.

2. TRANSPORT AND STORAGE
2.1. Transportation
Transport will be carried out by using a transpalet or lifting truck, as indicated in the following picture. The
machine will be transported completetly assembled. It is only necessary to turn the tool box.
2.2. Dimensions
Weight: 260Kg
2.3. Storage conditions
The machine should be kept in places that follow the requirements described below:
- Humidity between 30% and 95% without water condensation.
- Temperature from –25ºC to +55ºC or +75ºC without exceeding 24 h.
- It is advisable not to pile up machine or heavy stuff on them.
- Do not dismantle the machine to store it.
TWISTING MACHINE MT150 A INSTRUCTIONS BOOK 9
3. INSTALMENT AND STARTING UP
3.1.Instructions to fix it
While the machine is left down by the crane, it will be necessary to leave it properly so it hasn’t got to be
moved once it’s on the floor. In case this wasn’t possible, then it will be necessary to put it on a moveable
base and transport it to its proper place.
The machine will be fixed on the floor for its own weight, so it must be placed in a well levelled and flat sur-
facec.
3.2 Assembling to reduce noise and vibrations
This machine does not produce noise or vibrations due to its low speed.
3.3. Admissible outer conditions
Environment temperature: Between +5ºC and +40ºC without exceeding +35ºC as average temperature
Humididty:Between 30% and 90% without water condensation.
3.4. Instructions for connection to elecric supply
3.5. Safety systems for the user
Never for no reason touch the material while the machine is performing.
The machine location should be chosen counting on the space required for the material bar during its
distortion.
It mus be uniquely connected to the net with the indicated power (220v AC). If the line tensión is not the
correct one it could cause irreversible damage to the machine.
It is very important to properly connect the machine to the grounding plug.
