ELECTAC MT800 and MT900 WELDING FUME FILTBR
INTRODUCTION
Your MT800 or MT900 is a portable welding fume filter that uses a three stage
filtration system to filter welding fumes and return cleaned air to the work area.
The spark trap collects heavy particles, slag, pieces of mig wire etc. The fibreglass
insert inside the spark trap is supported by a steel gavze and stops sparks and very
hot pieces from damaging the main filter. It is important that the fibreglass is in good
condition and fitted correctly. Failure to replace the fibreglass when it is worn or
eaten away by hot sparks or molten metal can result in damage to the main filter or
in extreme oases a fire.
The disposable main filter cartridge, filters the welding smoke to 97oh efficiency,
99.996% to British Standard 3928 if the optional Hi-Efficiency filter is used.
MT800's have a single 1100 watt by pass motor, and MT900's have twin 1100
watt by pass motors to give extra suction and superior airflow.
OPERATION
Before operating your machine, it is important to check that your power supply is the
same as the machine, and that a suitable plug is fitted. All machines must be earthed.
Your machine is assembled at the factory, all that you have to do is to attach the flexible
hose to the spigot on the spark trap using the hose clip provided. The other end of the
flexible hose should be attached to anozzle with magnet, mig torch attachment, or the
take offspigot of mig extractor torch.
FILTER FULL LIGHT
All MT800 and MT900 models are now fitted with filter full indicators. This light is
situated adjacent to the on-offswitch. When illuminated the main filter cartridge should
be replaced immediately. It is always advisable to replace the fibreglass in the spark trap
at the same time as the filter cartridge.
