The present invention relates to an interface-forming device (x60) and a method for providing an electrically conductive power transmission interface (x30) on the end surface of a power cable (xOO) having at least two separate wires (x02) being electrically conductive, the cable (xOO) further comprising a reactive compound different from the wires (x02) for providing further features to the power cable (xOO). The method comprises the steps of providing an end section of the power cable (xOO), the end section comprising wires (x02) having wire ends, the end section further having the reactive compound, and successively adding electrically conductive particulates (x67A) onto the end section by bringing the conductive particulates being dispersed in a carrier fluid of a different material than the conductive particulates into contact with the end section.

A method for welding at least three cables, each with two conductors protruding from the sheath ends of the cables includes stripping ends of the first conductors and stacking from opposite directions atop one another forming a first stack. The stripped ends of the second conductors are stacked atop one another from opposite directions at a working distance from the first stack forming a second stack. The first stack is arranged in a welding area of a welding device and welded to a first welding point, while the second stack is arranged in a waiting area spaced by the working distance from the welding area. The first welding point is moved by the working distance from the welding area to a storage area, while the second stack is moved by the working distance from the waiting area into the welding area and is welded to a second welding point.
