Hi Steve,
Since my company sells both torches and tips for welding, brazing, and soldering, we hear from customers doing this work. One production company makes brass lamps and they use the auto-fluxers with several of our torches.
Because of the reaction of the flux to the torch tips - over time - they replace the tips due to corrosion after about 2 weeks of steady 8 X 40 hours. Even though they use a "non-corrosive " flux and though the brass they join does not suffer any corrosion, the torch tips do corrode because of the constant 1400F environment they see while delivering a steady flow of the flux directly into the brazing heats.
Non-corrosive at 30F - 100 F (0C to 45C) does not mean non-corrosive while flux-coated at sustained elevated temps.
