Abstract
Welding voltage and welding current supplied to a workpiece from a welding wire of a consumable electrode gas shielded arc welding apparatus are detected by a welding voltage detection means and a welding current detection means A replacement index for an electrode tip is computed by a replacement index computation means based on the average values of the welding voltage and welding current during arc time. A wear assessment means assesses the state of wear of the electrode tip by comparing the replacement index to a prescribed reference value. When the electrode tipreaches its prescribed wear limit (when its replacement index reaches the prescribed reference value), this fact is indicated by a replace tip indicator means
