Abstract:
1. A spot welding gun for resistance welding of objects, comprising a first arm provided with an electrode, a second arm provided with an electrode and a rod which is moveable in an axial direction, wherein said electrodes face one another, the axial direction of the rod is generally at right angles to the directions of said electrodes, at least one of the first and second arms is pivotally mounted, and the spot welding gun is adapted to press the objects to be welded together between said electrodes by axial movement of the rod, and allow welding current to flow between said electrodes, and wherein the spot welding gun further includes structural elements operatively connected to at least the pivotally mounted arm of said first and second arms and said rod, wherein the structural elements are in mutual engagement and one of the structural elements move translatively in the axial direction and forces another one of the structural elements to move translatively in a direction substantially orthogonally thereto to thereby force at least one of said electrodes towards the other of said electrodes as the rod moves axially, and said structural elements are disposed between the point at which said at least one of said first and second arms is pivotally mounted and said electrodes.
