Title: Soldering iron and heater longitudinally movable in housing - can be held near its tip for greater precision and convenience
Inventor: LIECHTENSTEIN RICHARD VON
IPC: B23K3/03
Filed: 1989-09-06
Abstract: Soldering iron (5) can move longitudinally inside the housing which surrounds it and the heating element (2), and can be locked in any of a number of different positions. The heating element is attached to the ering iron and moves with it inside the housing. The housing consists of two concentric tubes (30, 31) with an open air space between them, and sepd. by isolating spacer rings. Slots (44, 34) in the housing are provided to guide the movement of the soldering iron. The slot in the inner tube (30) is helical (44) in shape while that in the outer tube (31) is linear and longitudinal (34), so that the soldering iron can be moved by turning the tubes relative to each other. The soldering iron and its replaceable tip can be fully withdrawn inside the housing. USE/ADVANTAGE - This invention is used for the manual soldering of electrically conducting connections. Commonly used soldering irons suffer from the disadvantage that the iron cannot be grasped near its tip due to the layout of the components of the iron and the heat of the soldering element. This invention  overcomes this drawback and therefore allows more precise soldering work to be achieved.
