Step # 2:  Heat the work surface (not the brazing rod) until the work surface is hot enough to melt the rod, just as you would if using a solder.  DO NOT PUT THE ROD IN THE FLAME.  You must bring the temperature of the base metal up to the melting point of the HTS-735^II Fluxless Brazing Rod.  You must open the pores of the work surface with heat in order for the rod to penetrate the surface.

Step # 3:  When the weld is completed, always allow to cool naturally.  Propane works well on most weights up to 1/4 inch.  Note:  Remember the thicker the material, the longer it takes to reach the proper temperature.  On heavier work or to save time, you can use oxygen acetylene.  Always use a Rose- bud tip or a neutral flame with oxygen acetylene.  Never put the rod in the direct flame while brazing with HTS-735^II Fluxless Brazing Rods.
