Take the item out of the hot water bath periodically and test it’s malleability. Plastic components of circular cross section are rotated, one part in contact with the other, until sufficient heat is generated by friction to cause a melt at the interface, which solidifies under pressure when rotation is stopped to weld the articles together. Run the soldering iron tip back and forth over the seam to partially melt the plastic together.

To fully reinforce cracked plastic, seal the other side of the crack. While the pieces of plastic are still hot and movable, adjust them so that they fit together as best as you can manage. Push fit the tacking nozzle on the techspan hot air tool.
