Abstract: A soldering tip for a soldering device which comprises a heat generating or heat conducting base body, and which on the outside thereof has a contact surface that can be wetted by solder at least in sections. The material of the contact surface has a lattice structure. Charged elementary particles of at least one foreign material are incorporated into the lattice structure of the contact surface.

Abstract: The invention relates to a braking module for an asynchronous motor, in particular that used in a circular saw. In order that the braking process can run its course as gently and noiselessly as possible, independently of the inertial moment of the element driven by the motor, according to the invention provision is made for switching means (1, 2, 3, S1-S5) for separating the stator windings (U, V, W) of the asynchronous motor from the operating-voltage supply (L1, L2, L3) and for applying a direct current voltage (G1, G2) to at least two stator windings (U, V) in order to brake the asynchronous motor, a measuring unit (9) for measuring a remanence voltage on at least one stator winding (W), and a control unit (12) for regulating a braking current, which, for the purpose of braking, flows through the stator windings affected by the direct current voltage, in dependence on the measured remanence voltage.
