"Common Misconceptions
One big misconception is that alternative fuels cannot be used for welding steel because the flame is not hot enough. Considering that carbon steel alloys melt between 2,500o F and 2,800o F, this is quite inaccurate. The real reason is that alternative fuels don’t create any shielding gas. Conversely, a proper mixture of oxygen and acetylene with a neutral flame produces CO2, which in turn shields the molten weld puddle from atmospheric contamination. Realistically speaking, this is not much of a drawback, as most industries have substituted other processes for oxyfuel welding."

My question is, will these standard acetylene welding tips work with propane for brazing?

i suppose it may depend on your brazing rod, but i have brazed with propane, MAP, and Acetylene, knowing what i usaully have on hand it was probably Silvalloy 6 or 15.

Brazing / soldering uses a lower temperature melting point filler rod than the material being joined and is not the same as welding. Welding is using a filler rod that mostly matches the chemical composition of the welded material and when done properly, makes a homogenous weld that closely matches the composition of the parent metal when completed.

I have still never seen any Brazing Tips for Alternate Fuels. To run Propylene or Mapp, Propane Etc. in an Acetylene tip may not be the safest program.
