Replacing The filters in the MW1900 Welding Fume Extractor

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/micro-particulate);

  • Type of welding (each welding method behaves differently, MIG, TIG, MMA welding pprocess, etc.);

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

Instructions on how to replace the filters

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 which is supplied with the machine; the key opens the locks 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.
