I have never managed to get the weld I wanted wit those special rods like a tig does.
You also have to be careful with the gas tourch , it can really burna person or building .
And it wouldn't make any visual difference if you had to grind and polish welds afterwards.
As of being careful with torch...If you think you are at risk of burning yourself or burning a house down welding is N O T for you.
To av8tor... You remove brazing flux by washing it off with water. All fluxes..well most of them are phosphoric and fluoric acid based . Most of them i ever dealt with are water solubable so after weld cools down just take a wet rag to it .Or if size and circumstances allows you -drop the part in a bucket with water for a day or so.You can also chip it off with chipping hammer leaving ugly marks on the metal but i prefer water
