ALWAYS PRACTICE FIRST ON WASTE MATERIAL
WHEN USING LOWER HEAT GAS TORCHES, ALWAYS HOLD THE FLAME OF THE TORCH AT 90 DEGREES TO THE METAL TO BE HEATED WITH THE TIP OF THE BLUE FLAME 3-4 CMS FROM THE METAL SURFACE. THIS WILL GIVE YOU MAXIMUM HEAT EFFICIENCY.
Clean the area to be worked with a file, grinder, or wire brush. Ideally a clean stainless steel wire brush but most brushes will work.
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�2000 Flux Less Brazing Rod. Open the pores of the work surface with heat for the rod to penetrate the surface.
For threads and thin aluminium, tin the housing with the rod itself by scratching on the housing when the appropriate temperature is reached. For all other uses, use a tinning brush to tin the area with HTS�2000, when the appropriate temperature is reached. Then do your build up for excellent results. Finish the joint by stroking a small stainless steel screw driver blade along the molten rod.
When the repair is completed, always allow to cool naturally.
Propane works well on most weights up to 1/4 inch. Over that, use mapp gas or a more intense heat source.
Note: Remember that 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 Rosebud tip or a neutral flame with oxygen acetylene. Do not put the rod in the direct flame while brazing with HTS�2000 Flux less Brazing Rods.
REMEMBER: WELDING/BRAZING CAN BE DANGEROUS
ALWAYS USE THE APPROPRIATE SAFETY EQUIPMENT INCLUDING EYE PROTECTION
