An apparatus for short-arc welding comprises a controllable current source, means for controllably feeding a consumable wire electrode to the weld location, and a control unit for automatically adjusting the current source in dependence upon the weld sequence. The current source is arranged to provide welding periods divided into short-circuit intervals, arc intervals and optional rest intervals. The control unit includes means for continuously adjusting the relationship between arc interval energy and short-circuit interval energy in accordance with a predetermined function. |
