Under certain conditions surprisingly shorter bounce arcs cause stronger welds than the much longer lasting arcs, if the shorter lasting arcs, also shorter in length, are of the anode arc mode while the longer arcs are of the cathode arc mode. The different welding behaviour can be explained in terms of the corresponding arc roots. Thus it appeared that the different arc modes during the stages of the contact bouncing are influencing not only the material transfer but also the contact welding.
