WELDING EQUIPMENT

摘要

A welding voltage judging section (16) judges whether the set level of a welding voltage inputted from an input unit (11) falls within a predetermined range or not, and if it deviates from the predetermined range, a standard voltage corresponding to the set level of inputted welding current is selected from a unitary voltage table section (19), thus storing a welding voltage within an appropriate range constantly in the welding equipment even if a worker inputs conditions deviating from the appropriate range in the welding condition input work.
