A prototype device for connecting minute elements (such as pegs, bolts etc.) to sizeable metal surfaces is described in the paper. Engineering of this process and device design have been presented as well as basic measurements conducted during the weld-on process. The paper contains a schematic diagram of the power circuit based upon a thyristor rectifier bridge and block diagram of the control circuit. The device characteristics and operational parameters are also given.
