GASFLUXâ PROCESS
In the Gasfluxâ process the flux is introduced in the torch flame in a vaporized form as a result of the fuel gas flowing through a volatile liquid containing alcohol and boric anhydride in a saturator, an apparatus called AUTOFLUX. The flame is thus both fluxing and protecting. With this process bronze-welding can be performed without using the powders, pastes or coating usually applied. Its use remains efficient on all metals with the exception of aluminium. It is necessary to use a desiccator placed before the AUTOFLUX for wet gases. Automation of the Gasfluxâ process optimizes production rates.

AUTOFLUX APPARATUS
MODEL M3
Consists of a tank containing approximately 2,6 litres of Gasfluxâ liquid, and a control unit
- to connect the inlet and outlet fuel gas lines,
- to control the fuel gas/vaporized liquid mixture by means of three valves.
MODEL GM9
Equipped with three superposed tanks, allow a higher capacity.
MODEL RCF
This new apparatus is fitted with a filling connection which allows it to be quickly connected to a reserve tank previously filled in an appropriate room. As the Gasfluxâ liquid is inflammable, risks arising from filling the apparatus in the open air at the workstation, where flames and sparks are frequently present, are thus avoided.
