Abstract:
1. Welding device comprising: pliers arms holding electrodes, wherein the pliers arms apply a clamping force to the electrodes and a welding current passes through the electrodes, a force sensor mounted on at least one of the pliers arms, said force sensor being equipped with two support blocks on a side facing a surface of the pliers arm on which the force sensor is mounted, an interposed part disposed between the pliers arm and the force sensor, a mounting support having a general shape of an L, said support having a first branch and a second branch, wherein the first branch of the L-shaped support bears a collar clamping the pliers arm at a first location along a longitudinal axis of the pliers arm, said collar having an upper portion and a lower portion, wherein the upper portion is supported on the pliers arm on one side of the arm with respect to its longitudinal axis, and the lower portion is supported on the pliers arm on another side with respect to its longitudinal axis, and wherein the second branch of the L-shaped support extends from the first branch in a direction of the longitudinal axis of the pliers arm and holds the sensor on the pliers arm in a second location different from the first location along the longitudinal axis of the pliers arm, said second branch having a threaded bore in which a threaded clamping rod is engaged so that the clamping rod presses the sensor against the pliers arm via the interposed part, wherein the collar clamping the pliers arm constitutes the only securement of the mounting support along the longitudinal axis of the pliers arm.
