Feed the solder into the gap at the point where the flame meets the fitting. Capillary action will pull the molten solder into the joint. Continue feeding solder until a small ring of solder appears around the entire circumference of the fitting. For a ½‑inch pipe, you will typically use about ½–¾ inch of solder per joint. For ¾‑inch, about 1 inch. It is better to use slightly too much than too little – you can always wipe away excess later.
