Abstract

A jack, esp. a pneumatic jack, for electric welding, comprises a piston rod with 1 associated piston moving in a cylinder between a retracted posn. and an advanced posn. A passage is provided in one end of the cylinder for the control rod of a switch, the rod being actuated when the piston reaches the retracted posn., and seals are provided between the switch and the bore of the cylinder. The end of the cylinder is pref. provided with a recess in which the switch can be located, the passage for the control rod being located in the base of the recess. The device is used for e.g. spot welding sheet or plate travelling along a prodn. line and prevents damage to the piston-rod and/or serious interruption to prodn.
