1. INTRODUCTION
The machine described in this booklet is a portable welding fume extractor for extracting, filtrating
and de-odorizing welding fumes for light welding operations in electronic industries and in car
repairing workshops.
After passing through a rotary nozzle and a flexible hose having diameter 60 mm, the polluted air
reaches a filter cartridge. The final deodorization is obtained by means of a filter with active
carbons.
Upon delivery of the machine, make sure to check that it has not suffered any damage during
transportation. Should you find that the machine is not completely intact, get in touch with
our dealer immediately and do not use it.
The machine must be used exclusively for the purposes for which it has been built.
We decline all responsibility for any damage to persons or things resulting from improper use
of the product.

2.1.1 Highest Efficiency
The high-quality filtering materials of this machine make it possible to obtain an interception
efficiency of over 99%. Moreover, activated carbons remove almost all odours.
2.1.2 Low Noise Level
Low noise level is possible thanks to the disposition of the inner filters and to their high absorption
efficiency, and also thanks to the sound absorbent materials used in conjunction with a powerful
exhauster.
2.1.3 Handiness
Welding fumes should always be extracted before they reach respiratory tract. Fresh and pure air is
a condition that can not be given up in a salubrious working place. The solution is to extract the air
where pollution takes place by means of small and easily situated extraction nozzle.
The easily portable, light but reliable MW 8100 is the right solution to dealing with these fumes.

2.2 Working mode
Polluted air is extracted by means of the nozzle (part. 1, picture 1), equipped with a magnetized
base that allows its safe placing. It passes through the flexible hose (part. 2, picture 1) and reaches
the machine inlet flange (part. 3, picture 1), when there’s a labyrinth that prevents sparks from
reaching the CARTRIDE filter (part. 4, picture 1). The air flow passes the CARTRIDE filter and
then the cell with activated carbons (part. 6, picture 1).
Inside the machine, made up of a sturdy painted sheet steel, there is the electric motor (part. 5,
picture 1).

3. GENERAL USE AND SAFETY DIRECTIONS
•Never leave packing material (such as foam polystyrene, rivets, carton, wood and so on) within
children reach, since it could be dangerous.
•Before connecting the system, make sure that the connection point to the supply mains, implies
the presence of all necessary guards as foreseen by the Standards in force; also make sure that
the aforementioned connection point is compatible with the system supply mains.
•This equipment is to be used solely according to the purposes for which it was expressly
realized. Any other kind of use is to be considered as improper and dangerous. We are not liable
for any damages due to an improper use of the equipment.
•Before connecting the equipment, make sure that the ratings correspond to those of the supply
mains.
•Do not carry out maintenance operations when the machine is running or connected to the
electric power source. During these operations make absolutely sure to disconnect the machine
from the power supply line.
•If the machine does not operate properly DISCONNECT IT AND LET KNOW THAT IT’S
OUT OF ORDER. Apply to our After-Sale Service for repairing it and ask for original spare
parts.
The non-observance of what has been mentioned above could endanger the equipment safety.
•We advise the use of this machine only to responsible and duly qualified staff in areas
inaccessible to children.
•Should you decide not to use the equipment anymore, we recommend you to disable it by
disconnecting it from the supply mains and to dismantle it according to the regulations in force
in your Country.
•In case of accidental fall or nasty bumps, do not use the machine and contact our After-Sale
Service immediately since the equipment safety could be endangered.
•Work and keep the machine in a dry and sheltered place
•Do not disperse used filters in the environment but deliver them to firms
specialized in removal according to regulations in force.

•The use of the filtering unit for filtering and purifying fumes coming from
operations such as deburring, linishing, grinding and for extracting
inflammable vapours is forbidden
3.1 Use Directions
In order to use the machine properly proceed as follows:
1. By means of its handle (part. 7, picture 1); place the machine near the welding fumes.
2. By means of its magnetized base, place the nozzle where you must extract the fumes.
3. Connect the power supply cable to the external plug on the machine (picture 3);
4. Connect the power supply cable to the main electric grid (after making sure that the ratings
written in this booklet and on the machine correspond to those of the supply mains);
5. Press the starting button placed on the machine side. When it is in the position 1, a light
inside the button will show that the machine is in its ON position (picture 3);
6. When suction is not needed any more press again the button (position 0). The light in the
button will die out (picture 3).
7. Disconnect the power supply cable from the power source and from the external plug. Place
the machine where it can not cause problems to or hinder workers during their usual activities.

4. PRELIMINARY CHECKS AND INSTALLATION
When supplied, the machine is contained in a single packaging. The operator shall do as follows:
•Unload the packaging
•Carry out the unpacking
•Make sure that the packaging contains all parts and that they were not damaged during
transport otherwise contact our Reseller.
•Place the flexible hose on the inlet flange of the machine and fasten it by means of the
hose clamp.
•Connect the power supply cable to the main electric grid (after making sure that the
supply voltage/frequency are 110 V/50 Hz);
•Use the machine as described in paragraph 3.1 Use direction.
Before connecting the machine to the main electric grid,
make sure that the ratings on the machine correspond
the ones of the supply mains

MW 8100
PORTABLE WELDING FUME EXTRACTOR MW 8100
5. MAINTENANCE
Do not carry out any maintenance procedures when the machine is connected to the supply mains.
During this phase we recommend you disconnect the cable form the power supply mains. For a
keeping a good machine efficiency, do as follows:
•Check the feed cables on a daily basis
•Keep the machine in a sheltered place
•Make sure that the flexible hose is not damaged in any point
How frequently the filters are monitored will depend on the type and frequency of welding carried
out. Regular testing of the extraction capacity of the machine is required, reduction in this capacity
means the saturation of the cartridge filter, which will need replacing when fully saturated.
5.1 Replacing the Cartridge Filter
The cartride filter is part no.4 of picture 1.
1. Make sure that the machine is disconnected from the power supply mains. Then loosen the clips
of the cover (front side - reference fig. 4) and open it.
2. Unscrew the blade-screw.
3. Take away the bar.
4. Take out the filter and insert the new one, making sure that it is well inserted.
5. Replace the bar in its original position.
6. Screw the blade-screw again.
7. Close the cover carefully by means of its clips.
5.2 Replacing the Filter with Activated Carbons
The filter with activated carbons is the part no. 6 in picture 1.
1. Make sure that the machine is disconnected from the power supply mains. Then loosen the clips
fastening the cell (back side - reference fig. 4) and take it away.
2. Unscrew the four screws on the cell and replace the carbons with the new ones. Then screw the
screws again.
3. Refasten the cell with the new activated carbons by means of the clips.
