Abstract
The present invention relates to a method for measuring the free wire length in hot-arc or short-arc MIG/MAG welding by making use of the typical behavior of the current or the voltage in the bead short-circuit situation, in which the voltage rises in different ways depending on the free wire length. The phenomenon can be used for measuring the free wire length.
