The present invention refers to a control method and welding equipment for MIG/MAG-welding with presence of short-circuiting droplets between an electrode end and a workpiece. The method comprises establishment of a short-circuiting time, establishment of an arc time, and controlling the energy supplied to the electrode. The energy supply is controlled in such a way that the energy supply is increased if a measured short-circuiting time of a total period time, where the period time is the sum of the short-circuiting time and the arc time, exceeds a defined adjustable set value and decreases if said short-circuiting percentage goes below said set value.
