Hi, sorry if this question has been asked here before.
The nearby supplier of brazing equipment surprisingly doesn't have any brazing fluxes.
They do have brazing rods that contain flux but couldn't give me much information about them.
I only know that these rods appear to be CuZn40 brass tubes filled with some flux.
I want to do fillet brazing and I wonder if I can get away without any additional flux, only using these rods. I've found some technics of using flux covered rods but these technics don't seem to be appliable when it's the other way around.
