Heat Joint and Apply Solder

What happens here

Using a MAPP gas torch, begin heating the fitting of the joint, not the pipe. Move the flame evenly around the fitting to ensure uniform heating. When the flux starts to bubble or a greenish tint appears in the flame, the pipe is hot enough. Touch the tip of the lead-free solder to the seam of the joint, opposite the flame. The heat will draw the solder into the joint, filling the gap via capillary action. Continue feeding solder until a silver ring appears all the way around the joint.
