1. INTRODUCTION
Product Description
The MW 8100 machine described in this booklet is a portable unit for the extraction, filtration
and deodorization of welding fumes in the electronic industry in general, in bodywork
departments and for small welding.
Polluted air is sucked in by a brush motor with integrated aspirator positioned inside the
machine casing. Captured is done by an adjustable cap and through a 60mm diameter
flexible tube reaches a filtration cartridge. After the fan fume will be finally expelled. The final
deodorization is carried out through an activated carbon cell.
The main components of the machine are listed below:
1. Machine carpentry
2. Adjustable suction hood
3. Anti-spark brassed cloth
4. Flexible hose
5. Suction flange
6. Filter cartridge
7. Brush motor
8. Handling handle
9. Socket with switch and fuses
10. Internalsoundproof KIT
11. Activated carbon cell
12. Expulsion flange

Final Use
!
The MW 8100 machine, produced by MasterWeld, is equipment designed for the extraction,
filtration and deodorization of tin welding fumes in the electronic industry and in general
the fumes from small welds in bodyshop and in mechanical workshops.
Not authorised use
The intended use of the machine is the suction of welding fumes in industry and body shop:
it is forbidden to use it to suck up other substances (dust, liquids, vapors, etc.), especially if
flammable, explosive, corrosive other than those commonly contained in the emissions of a motor
vehicle.
The machine must only be used in a work environment protected from atmospheric agents.
The machine must be used with caution,making sure that the power supply cable and flexible hose
are not placed in dangerous areas or where they can hinder other operators.
MasterWeld declines all responsibility for damage to things or people deriving from
improper use of the machine.
The machine was not designed to be used in a potentially explosive atmosphere: its use in
environments where there is a risk of fire or explosion is prohibited.
If you need to install the machine in an environment whose atmosphere is potentially explosive, it
is recommended to contact MasterWeld in advance.
The nozzle must allow the entry of air at room temperature in a ratio of 1: 1 with the aspirated
fumes. This is necessary to lower the average temperature of the sucked gases, preserving the life
of the internal components of the machine.
It is forbidden to use it with systems for capturing and conveying the flow rate that do not allow the
entry of air at room temperature as prescribed.
MasterWeld disclaims any liability for damage to the machine itself, to people or property
caused by the incorrect use of the collection cap or the use of inappropriate hoods.

Residual Risks
The Risk Analysis carried out by MasterWeld on the product and contained in the Technical File,
made it possible to eliminate all the main sources of danger related to the use of the machine;
however, there are some unavoidable risks that will be listed below:
ELECTRICAL RISK: It is forbidden to perform repairs or maintenance on the machine when it is connected to
the electrical power system; however, should it be necessary to operate with the machine powered on, this
practice can only be carried out by Qualified Personnel (PQ), with expertise in the electrotechnical field, or by
an Authorized Technician (TA) appointed by MasterWeld
Adopt all the precautions according to the regulations in force if you have to operate with the machine
powered on: wear insulating gloves and shoes and use insulating mats and insulated tools. Also check
that the system to which the machine is connected is protected from leaks and short circuits, as
required by current legislation
RISK OF FIRE OR EXPLOSION:
The machine cannot be used in environments with a high risk of fire or explosion. It is forbidden to
store, even temporarily, potentially flammable or deflagrating substances in the rooms where the
exhaust gas extraction system is installed.
RISK OF BURNS: During work operations, the machine, especially on the ejection side, can reach high
temperatures with consequent risk of burns. Use heat-resistant gloves for handling the machine.
RISK OF FAILURE OR MALFUNCTIONING: Long use of the machine in particularly severe environmental
conditions (brackish environment, excessive temperature, condensation, presence of dust, exposure to
atmospheric agents, etc.), can cause malfunctions or failures of the product and compromise its safety.
Respect the requirements indicated in the "Safety Warnings" relating to the work environment,
reported in this Use and Maintenance Manual.
RISK OF INCORRECT INTERPRETATION OF SAFETY ADHESIVES: Following the identification of the main
sources of danger that emerged from the Risk Analysis, Safety Stickers, with unified symbols, were applied to
the machine to signal these sources of danger. Over time, these stickers can become illegible or difficult to
interpret due to aging or wear.
The user is required to immediately replace the Safety Stickers that should become illegible due to
aging, wear or damage.
To limit these risks, it is recommended to comply with all the indications given in this Use and
Maintenance Manual, not to force or inhibit the safety of the machine and to wear the personal
protective equipment (PPE) provided.
Please note that all personnel involved in the use and maintenance of the machine and the plant in
which it operates must be aware of the relevant safety standards.
Safety Stickers
On the machine are applied stickers bearing symbols and / or safety messages; their location and
the nature of the danger reported are indicated below.
SYMBOL
DESCRIPTION
RISK OF ELECTRIC SHOCK
The machine's power socket (fig. 1) and the power cable are subject
to the risk of electrocution due to the presence of electric parts.
It is forbidden to touch all electric parts.
It is strictly forbidden to extinguish fires using water, due to the
presence of electric parts.
