The present invention relates to a soldering tip fastening sleeve (3) comprising a soldering device fastening portion (7) and a soldering tip fastening portion (6). The soldering device fastening portion (7) has an internal measurement (15) and an external measurement. Also the soldering tip fastening portion (6) has an internal measurement (16) and an external measurement (14) as well as a collar holder (10). The soldering tip fastening portion (6) and the soldering device fastening portion (7) are associated with different ends of the soldering tip fastening sleeve (3). The soldering tip fastening sleeve (3) according to the present invention is characterized in that the collar holder (10) is provided on a first subsector (17) of a circumference of the soldering tip fastening sleeve (3). The present invention also relates to a soldering tip (2) comprising a soldering portion (4) and a fastening portion (5). The soldering tip (2) is adapted to be fixed to a soldering device (30) through the fastening portion (5), a maximum external measurement (5a) of said fastening portion (5) being equal to or smaller than a maximum external measurement (4a) of the soldering portion (4), or the soldering portion being angled. The soldering tip (2) according to the present invention is characterized in that the fastening portion (5) comprises a collar (9).

A method or process of fabricating a solder cartridge and solder cartridge made according to the process is disclosed. The solder cartridge made according to the process provides a self-temperature regulating solder tip for an inductive current soldering station having improved heater quality and stability with reduced manufacturing costs.

The invention relates to a soldering tip assembly for an electric soldering device, in particular a soldering iron. The soldering tip assembly is designed to be releasably arranged on a soldering device handle which has a heating element, and the soldering tip assembly has a sleeve with a soldering tip provided on the distal end of the sleeve. The sleeve has an opening at the proximal end for introducing the heating element, wherein a holding element which at least partially surrounds the sleeve in an annular manner and a spring element which is provided between the holding element and the sleeve are provided, the spring element pushing the holding element in the distal direction. The sleeve has at least one stop arranged distally from the spring element. The stop secures the holding element against the soldering tip assembly in the distal direction.

A soldering tool may include a power unit including a controller, a tool body configured to interface with the power unit, and a tip portion operably coupled to the tool body. The tip portion may include a tip that is heated to melt solder by a heating element controlled by the controller. The tip is operably coupled to the heating element via a braze joint. The heating element may be operable at a first temperature range for melting the solder and a second temperature range, higher than the first temperature range, to facilitate forming or braking the braze joint.
