10. VACUUM SYSTEM OVERVIEW
The DGP-PG3-V2 comes with a tool cabinet and integrated vacuum system for the collection of tungsten
dust. This feature has become very popular due to the disclosures in the past few years about the danger of
inhaling dust from the commonly used 2% Thoriated tungsten. This danger is because 2% Thoriated tungsten
is radioactive and is a known cancer causing element. Please contact your local OSHA office if you would like
more information about this issue. In addition, we offer free samples of non-radioactive alternative tungsten,
which performs better in most applications.
It is impossible to contain all of the lightweight dust particles that deflect quickly off the wheels from grinding.
The vacuum system offers a way of collecting the majority of the dust that is produced while grinding and
cutting tungsten electrodes. Replacement vacuum filters are in stock at the factory and ready for immediate
shipment. Installation instructions come with replacment filters. Filter replacement is a very quick and easy
process.
