Soldering irons offer a multitude of tips - Brief Article

A range of 120 interchangeable soldering tips for hand soldering applications, specified with Ersa's range of temperature-controlled hand soldering stations, will be on show at OnBoard as part of Blundell's display.

This splint is made from a disposable hypodermic syringe. The plunger is discarded and the body is longitudinally split with a pair of stout scissors. To prevent trauma, the edges are rounded off with a blunt file and a number of small holes are made in the body of the syringe with a hot, large-bore needle to allow for evaporation of sweat and prevent sogginess. We used an ordinary paper punch (see figure) or a soldering iron for the same purpose with comparable results. Alternatively, a piece of gauze wrapped around the finger to be splinted would probably serve this purpose. The splint is then placed on the dorsal or volar aspect of the finger and secured in place by two strips of adhesive tape. Depending upon the size of the finger, a custom-made splint to fit an individual finger can be created using the appropriate syringe-usually 10 cc for adults and 5 cc for children are suitable; 20 cc can be used for the thumb. This splint compares favorably with other methods used to prepare such a "gutter splint" that require additional materials, such as wood, steel, PVC, plaster of Paris or aluminum. It can easily be made, is convenient to use, nontraumatic, light in wei ht and practically free of cost.

All the soldering irons have positive temperature coefficient heating elements, and can operate for short periods at three times the power of the control unit.
