When welding precious metals, there is always a condition that occurs in an internal atmosphere. This is in order to retain the properties of the materials used and to prevent unevenness and corrosion by welding, in particular pipes and rorformdele. Usually this is done by the filling of the canister with gas, resulting in a very large gas consumption. In order to save the expensive gas, it is close to a welding point on both sides of the weld with a bagga system. This gives you a great saving of gas and the time spent minimized filling. This is ensured by an integrated gas supply. This is done by means of a purge system which is crucial for achieving high weld quality. Our flush system called Fast Purge Multi-size, is a system that is inflatable and heat resistant to 250 degrees. Very light and foldable.
