Abstract:
Provided is an arc welding display technique which enables an operator to verify information during welding, when performing arc tracking welding, and which enables accurate arc tracking welding to be performed on the basis of the verified information. This arc welding display device is provided in a welding device provided with a weaving function whereby a torch is caused to oscillate relative to a welding direction, wherein at least one of a welding current and a welding voltage during arc welding is displayed on a screen, divided into fixed periods each including at least one weaving period. Preferably, an average welding current for each fixed period including at least one weaving period, or an average welding voltage for each fixed period including at least one weaving period, is subtracted from the welding current or the welding voltage during arc welding, and the value after subtraction is displayed on the screen.
