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 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.

4.INSTRUCTIONS FOR THE USAGE
4.1 Instructions for the adjustment
This machine hasn’t got any adjustable element, with the exception to any kind of repair.
4.2 Waste hazards (That cannot be eliminated). Hazard caused by fitted elements
Always bear in mind to keep hands off the moveable parts of the head to prevent any hazard of arms or
finger shearing.
4.3 Information about forbidden usage methods
Do not use any tooling that hasn’t been supplied by the manufacturer, in order to avoid the breakdown of
any element that could hurt the operative.
4.4 Instructions to locate breakdowns and to rearm the machine
The machine does not tend to breakdowns because of ite machanism. The only possible breakdown would
be the change of th operation fuse, in the electric part. This fuse is located inside the command panel or
electric box. It is necessary to get the machine unplugged from the electric power supply and then unscrew
the cover of the command panel.. In the electronic card you will find the operation fuses. In case they have
to be replaced, find ones with the same electrical features of the ones changed.
Other possible causes of the fault could be an error message produced by the frequency inverter. Please
checkup the inverter handling book on section for Faults and Errors.
4.5. Instructions for learning how to work with it
In order to learn how to operate with this machine, place the basic tooling and notice how to position the
stand points, see the pictures sequence in the last section. There are also different thick parts and tops in
order to adjust the proper height for fastening.

6. EXPLANATION OF ITS PERFORMANCE
6.1. Introduction
The electronic control module has been specifically designed in such way that is rules, either one or the
other machine: MT150A or MT150R.
What is stated above could be easily understandable since these two machines have similar characteris-
tics, and so from now on when referring to either one or the other we will use a generic term, such as
“twisting machine”.

TWISTING MACHINE MT150 A INSTRUCTIONS BOOK 13
6.3. Equipment performance
The system described offers the chance to work in two different modes: manual mode and automatic mode.
6.3.1. Manual mode
The machine works this mode on default, however it is to be remarked that working on the automatic mode is
better, whenever there is a considerable mass production on the same memory.
In manual mode, the user may turn right or left by using the two buttons previously mentioned, so the torsion
can be carried out on his will and desire.
Performance is as simple as when pressing one of the buttons , the machine turns until the the user stops
pressing it.
Once the user thinks he’s got a good point start the torsion of a piece; he inserts it in the mould of the machi-
ne and makes the torsion of that piece, to one direction or the other, depending on the selected button. In
order to finish the torsion just stop pressing the button that was being pressed.
Now that we have twisted the piece, it is necessary to press the button "Left turning"or "Right turning" in order
to pull out the piece since it happens that it is difficult sometimes to get the pieces out once the operation has
been finished.
(Always bear in mind all restictions concerning the kind of torsion and that the pulling out will always be made
the opposite direction of the torsion, and it will make the machine go back a few degrees to enable the co-
ming out of the piece.
7.3.2. Automatic mode
The performance principle of this machine is the same of that one at the Manual mode, the difference lies in
the fact that this mode is used for the mass production of differen pieces,which makes a bit unuseful the use
of the machine in the manual mode.
First, once the user has inserted the mould in the machine, he should specify the starting point of the torsion
to be made. It is necessary to press the "Programming"key then (it will read in the display a label saying
“Define starting point of the torsion").Then he should specify the point the machine requires to define the tor-
sion by using the the buttons for "Left turning"and "Right turning". So when he finds the proper point to insert
the piece in the mould, it is required to stop pressing the turning button to either direction, and to press again
the "programming" button (There appears a label on the display similar to that of "Define kind of torsion").
Once we have reached this point, the user should select whether he want to make a round or square torsion,
since he has alrady put the piece in the machine.in order to do that he has to make it by using the button, no
matter if it is the aforementioned one "Round torsion", or the "Square torsion"one (It will appear a label on the
display similar to "Define kind of torsion", NºP:00 Reference: 0000". It is important to point out that when ma-
king the circle torsion it is only permitted to do it in left direction, for safety reasons, it doesn’t happen the
same when it comes to square torsions since they can be made to both directions. However once the torsion
has been started to one side, it is not possible to go back or change its direction until it has been completely
finished.

TWISTING MACHINE MT150 A INSTRUCTIONS BOOK 14
Now the user should be pressing the “Turn left” button or the “Turn right” button in order to make the torsion
of the piece (Keep in mind the shortcomings according to the kind of torsion). Once the user thinks the pie-
ce is finished he should press the button according to the 8 memories at his disposal (Memory buttons), so
the piece made could be registered then a label will show up on the display: “Registering torsion, Referen-
ce:nnnn”)
Afterwards, another label will show up reading: "Make unlock". It is required now to use the buttons for
"turning left" and "Turning right", it is necessary to specify the point required for the further extraction of the
piece.
The user might be pressing the "Turning left" or "Make unlock" button at this point (keep in mind the short-
comings regarding the kinds of torsion, the pulling out will be carried out always the opposite direction of
the torsion. When the user sees that the piece has been released he should activate the button according
to ("Pulling out" button) in order to register the pulling out operationthet has been carried out, however it is
to be remarked the fact that in case this pulling out does not allow the user to get the piece out easily, it will
be necessary to repeat the whole process again.
In order to make diferent pieces, just follow the steps that have been previously described and end up the
operation registering these torsions in the different memories.
Once you have used all 8 memories it is not necessary to delete any of them to make a new torsion since it
is automatically erased once you program a new torsion on an already existing memory .
In case an already registered torsion has to be repeated, just press the memory button that defines the tor-
sion to be done and follow the indications described in the LCD display.
Moreover, the user has the possibility to control the number of pieces made with each memory tha machine
has. For that, a message will show up on screen reading "Nargesa MT150A, in StandBy" or "Nargesa
MT500A, in StandBy" (Depending on the machine that is performing at the moment the user should press
the button for "Control of manufactured pieces" (a label will show up on the display reading: "Select Me-
mory"). Once this has been done the user ought to select the memory to be displayed so a message will
come out on screen reading "Memory: 01, CNT to delete". In case the user decides to delete this memory,
now that the number of manufactured pieces has been checked, just press the control button again (CNT).
There is also the "Escape" key that allows to go back to the screen, on default ("Nargesa MT150A, in
StandBy"), it can be used whenever there is no torsion in process, if it is so , it is necessary to finish it befo-
re going back to StandBy.
This system has also got a safety system that makes the machine locate the starting point when activated
after being stopped for a time, this starting point is the one from where all references are taken. Like this,
and even if the torsion was made again, the one to be made will be found in the memory that had been se-
lected.
The machine also has an automatic control system that alerts in case the machine has lost refrence for any
reason. It does not happen a lot however, just in case, the user must follow the stepsthat are clearly detai-
led in the LCD display.

TWISTING MACHINE MT150 A INSTRUCTIONS BOOK 15
Last but not least, it is necessary to point out that the system developed is according to the safety regula-
tions and that in case of any emergency stop situation, the machine won’t be able to work again until it rea-
ches its normal way of performance; it is then when the user has to find a new starting point in order to ma-
ke sure that references are still reliable (always if the user agrees with the new situation and following the
indications given in the display, press “ESC” key).
