An electrical connector for removably engaging a welder to a spot welding tool having a first arm in a pivoting engagement to a second arm. The connector features an electrically conductive member engaged to or forming a powered translating shaft of a welder which is surrounded by a housing. The connector engages within a passage formed in a coupling to communicate forward and rearward movement and electric current to a first arm of a spot welding tool.

A resistance welding device is configured for use in combination with a resistance welder having a translating welding electrode. A first arm of the welding device is in a translating rotational engagement with a second arm thereof. The first arm of the device is engageable to a translating electrode from the resistance welder. Translation of the welding electrode of the resistance welder moves first and second electrodes to contact metal therebetween and spot weld the metal.

A melt cutter includes a case, an electricity-connecting portion, a heating device, a working portion, a control portion, and a heat-dissipating device. The case has a heat-dissipating zone. The electricity-connecting portion is disposed in the case for connecting with an electricity source. The working portion is disposed in the case and has a gap with changeable size for clamping an object. The control portion alternatively triggers the heating device to heat and to transmit heat to the working portion, and it also reduces the size of the gap for melting and cutting the object. The heat-dissipating device is disposed at the heat-dissipating zone and is electrically connected with the electricity-connecting portion. Thereby, the heat-dissipating device helps air communication between interior and exterior of the case.

A new weld configuration is used to obtain a robust and consistent resistance weld between the tabs of an anode current collector and the casing of an electrochemical cell. This is done by adding a resistive transferable electrode tip between at least one of the welding electrodes, preferably the movable welding electrode, and the stacked parts that are being joined together. The purpose of the transferable electrode tip is to generate a sufficient amount of heat during the welding process so that the stacked parts are joined together without adding any product functionality. In one embodiment of the present invention, the transferrable electrode tip is a stainless-steel ball, the stacked anode current collector tabs are of nickel, and the cell casing is of stainless-steel.

A device for positioning in the body of an animal, the device comprising a first portion and a second portion that may be positioned in contact with one other, the first portion and the second portion each comprising a biocompatible conductive thermoplastic material, such that when the device is positioned in the body of an animal and electric current flows from the first portion to the second portion, heat is generated by electrical resistance at the point of contact between the first portion and the second portion so as to melt regions of the first portion and the second portion, and when the electric current is thereafter terminated, the melted regions of the first portion and the second portion re-solidify so that a weld is formed between the first portion and the second portion.
