Somewhat related to this thread, I read in the aluminum welding booklet which Kent publishes that his flux should not be mixed with distilled water only mineral water. I would have thought that mixing the flux with an unknown of minerals and salts would be a problem. Any explanation? Is this true with all such fluxes or just Kent's? I have always tried to use distilled water with other fluxes and never had a problem that I am aware of. Perhaps mineral water would have yielded better performance. Sparkling or non?
