A welding electric current is suppled to a tiltable resistance welding gun having a pair of electrodes which grip a workpiece while effecting resistance welding thereon. A power receiver terminal on the resistance welding gun and a power supply unit are connected to each other when the electrodes grip the workpiece therebetween, and the welding current is supplied from the power supply unit to the power receiver terminal. When the electrodes are separated from the workpiece, the power receiver terminal and the power supply unit are disconnected from each other.

Method and apparatus for supplying electric power to resistance welding

A fluid diverging system provides a passageway for supplying a fluid from a single supply source to a plurality of sections requiring the use of the fluid and for discharging the fluid from these sections to a single discharge portion. The fluid diverging system includes a plurality of fluid diverging blocks separably connected to one another longitudinally in a row. Each of the blocks has a through-hole longitudinally passed therethrough, and a communication passage communicating with the through-hole and capable of being connected to external fluid transfer means. Joint means connecting these blocks enable a fluid-tight communication of these blocks with one another. This makes it possible to use the fluid diverging system in an optical form only by increasing or decreasing the number of the fluid diverging blocks in accordance with an increase or decrease in number of the section requiring the use of the fluid.

Fluid diverging system

A fluid pressure operated spot welding apparatus is disclosed, in which one of a pair of electrode arms initially is moved from a closed position of the electrodes in a rectilinear path perpendicular to the other electrode, and subsequently is swung in an arcuate path to a retracted position in which the said one electrode is positioned rearwardly and remote from the said other electrode, the apparatus also providing for the substitution of alternative workpiece supports in a readily interchangeable manner.
