GENERAL INFORMATION ON THE MACHINE

Par Description

General description of the machine

The portable unit is the ideal solution for the extraction and ltration of welding fumes from variable position work stations with discontinuous welding operations. The gases and fumes given off during welding are captured to prevent them from spreading throughout the workplace; the air containing the contaminants is thoroughly filtered and recycled back to the workplace. This unit is designed for the suction and treatment of dry fumes produced by work processes such as spot or discontinuous welding wire or electrode welding, hence involving the emission of low concentrations of pollutants containing gas or suspended welding slag. National and international regulations allow the use of these devices in replacement of conventional air

cleaners with an articulated arm in special conditions such as occasional or discontinuous use (e.g. 20 hours out of a 40 hour working week) or in conditions in which the work processes are dynamic to the point at which a fixed capture system is ineffective. In addition, the filtration unit also purifies the air in the surrounding environment, thus not only treating the area contaminated by the work process but simultaneously creating air exchange in the workplace and further decreasing the level of pollutants present. To comply with regulations and to obtain high quality filtration with consequent safety for the operator, it is essential to perform correct maintenance/ periodic replacement of the filters, which, in our units, provide high capacity for accumulation of contaminants and very low costs for the ltration sections.

MACHINE CHARACTERISTICS

The portable unit is fitted with a high efficiency suction fan in a negative pressure sound-insulated compartment which acts as flow calming plenum to reduce the turbulent flow of the treated air before it goes out through the special output grilles. The excellent manoeuvrability and highly ergonomic use of this unit ensure it can be utilised in several different work stations, while the flexible arm is able to operate over a working radius of 3 m. The machine is supplied as standard with an electrical control panel, IP65 protection, made up of:

- ON/OFF switch;

- magneto-thermal protection (for electric motor);

- differential pressure switch with simultaneous temperature control;

- machine power supply signal (white light);

- machine on signal (green light);

- clogged filter signal (red light).

According to the version, the filtration section is made up as follows:

Par Description

Control panel and electrical panel on the machine

The machine is equipped with an electrical panel which acts as control panel and as container for the protection devices of the electric motor.

The control panel is on the front of the machine near the handle. The control panel is covered by a painted plate with the adhesive strip as shown below.

The position of the panel makes it easy to switch the machine on and off and to keep all the machine functions under control by means of the indicator lights on the panel.

The handle protects the panel against accidental knocks which could damage the equipment thus making it impossible to control the machine.

The label above the panel helps the operator use the equipment and check its correct operation.

INITIAL START-UP

Par Description

Use of the suction arm

The machine is fitted with one suction arm which must be assembled separately using the screws supplied in the package. The arm's flange must be fixed to the plate, with pre-drilled holes, on the air cleaner.

The suction arm can rotate 360° about the central axis during the rotation phase.

Arm closing and/or opening operations must be carried out only from the front of the machine with the operator facing the control panel.

The use of the suction arm outside the recommended range may cause the machine to tip over. In fact, when movements are carried out along the longest side of the machine the force exercised is such as to move the barycentre and act as a lever lifting and/or tipping over the air cleaner in the direction of the operator moving the arm.

MACHINE MAINTENANCE

Par Description

Replacing the filters

The filter lifecycle and interval for the replacement of clogged filters may vary according to the type of use.

There are many variables to be taken into account, such as:

• material to be welded (every material and alloy produces different fumes/microparticulate);

• type of welding (each welding method behaves differently, mig, tig, electrode, etc.);

• elements in contact with the equipment (for example oil, fat, paint, etc. make the fumes generated more “aggressive”).

When a filter is clogged it is signalled by a special indicator light on the control board; The light refers to a differential pressure switch housed inside the electrical panel.

To replace the filters it is necessary to use the special triangular key (Photo 4 - 1.1) which is supplied with the machine; the key opens the lock of the filter inspection door.

The door gives access to the filtration section; the filters can be simply removed by pulling them outwards one at a time.

It is important to take into account that it may be difficult to extract the filtration section due to the gaskets along the perimeter of the filters. The gaskets (which are pressurised) hermetically seal the entire filtration section and guarantee that all the particulate extracted is filtered by the whole section.

The filters must be extracted starting from the lower one which has a frame to hold on to and pull; the other filters will then come out more easily as they will no longer be pressurised.

It is recommended to replace all the lters in the machine at least once a year for maximum suction and ltration efciency.

Pocket bag lters use materials that can be completely incinerated/disposed of without the release of any toxic gas.

Corrugated lters are made with inert materials which, if they are not contaminated with toxic-noxious substances deriving from their use, can be disposed of as solid urban waste.

Metal lters are made with inert materials which, if they are not contaminated with toxic-noxious substances deriving from their use, can be disposed of as solid urban waste.

It is recommended to clean this lter at least once a week for maximum efficiency of the machine.

It is recommended to clean this lter at least one time every two weeks for maximum efficiency of the machine.

It is recommended to clean this lter at least once a month for maximum efficiency of the machine.

he activated carbon are materials, made predominantly of carbon in the form of microcrystals of graphite, treated so as to obtain a porous structure with a large internal surface area. Thanks to these characteristics they have high capacity adsorbent and are able to absorb, during the contact phase, many types of substances, attracting the molecules in their inner surface. The absorbent capacity of the filter is given by the types of pollutants and from their combination.

* The fourth filtration stage is only with the Active Carbon Kit, when not present, as in the standard version, there is a

polyester

microfiber panel in order to reduce noise emission.

Carbon lters are made with inert materials which, if they are not contaminated with toxic-noxious substances deriving from their use, can be disposed of as solid urban waste.

It is recommended to clean this lter at least once a

year

for maximum efficiency of the machine.

For the replacement of

carbon filters, unscrew the

side vents on the sides, on

which are threaded, as

shown above.

You have to pull out the

old filter from the grill then

insert the new one.

NOTE A

The cleaning intervals vary according to the type of fluid conveyed and its concentration and also according to the type of work environment in which it is used. The end user must therefore dene a cleaning interval suitable to always keep the machine perfectly clean; the accumulation of material on the fixed parts must not be more than 5 mm thick.

NOTE B

A special device fitted on all equipment signals the need to replace the lters. It is however recommended to check whether the filters are clogged for maximum suction and machine efficiency; for this reason the cleaning interval described in the filter paragraph should be respected and the entire lter set should be replaced at least once a year. The lters deteriorate even if they are not used very often.

NOTE C

The fan extractor must be monitored at intervals established by the user to check that it is good working order, to check for faults or damage to the impeller and to check that the electric motor is in good condition.

NOTE D

This is the lifecycle defined for the bearings, however due to external factors such as increased vibrations for a certain period of time the replacement of the bearings may have to be carried out at shorter intervals. At the end of their lifecycle, the bearings should be replaced even if apparently they seem in good condition.
