Abstract
A welding voltage judgment portionof judging to see if a predetermined value of welding voltage inputted from an input devicefalls within a predetermined certain range is provided, and when the aforementioned welding voltage judgment portionjudges that the predetermined value of welding voltage deviates from the certain range, a standard voltage corresponding to the aforementioned inputted predetermined value of welding current is selected from a unitary voltage table portion, making it possible to always keep the welding voltage stored in the welding device within a proper voltage range even when the worker inputs conditions deviating from the proper range during the operation of inputting welding conditions.
