A solder preform with predisposed flux to be located adjacent to a gap formed between multiple solderable surfaces such that upon heating, the flux wicks into and prepares the solderable surfaces prior to the solder melting and wicking into the freshly prepared gap. In plumbing applications, this invention can be located inside a pipe fitting adjacent to the end of an inserted pipe. Upon heating, this invention will make a sound solder joint by wicking into the annular region formed between the fitting and the pipe. This invention includes a dispenser for solder preforms that has features to align a solder preform with the centerline of the receiving pipe fitting into which it is to be inserted. In addition, the dispenser has features to insure the solder preforms are released one-at-a-time into the receiving fitting.
A dispenser containing a plurality of stacked solder preforms for use in inserting the solder preforms into a tubular member, the dispenser comprising a cylindrical magazine for storing stacked solder performs and stacked solder preforms advancable through the cylindrical magazine sequentially to and through an open end of the cylindrical magazine, the dispenser having a lip at the open end of the magazine with a tapered inner surface to align a tubular member with a preform located at the open end of the magazine for insertion of a preform into the tubular member.
A dispenser containing a plurality of stacked solder preforms for use in inserting the solder preforms into a tubular member, the dispenser comprising a cylindrical magazine for storing stacked solder preforms and solder preforms movable through the cylindrical magazine sequentially to and through an open end of the cylindrical magazine for insertion into the tubular member, each of the preforms having solder flux disposed on the exterior of the preform, the cylindrical magazine comprising means for preventing a user from coming into contact with the solder flux.
