The Method of the Building Voltage-Current Characteristics of the Welding Power Sources
Information-measuring system meant for measurement and storage of volt-ampere characteristics of welding supply sources is considered in the article. The advantage of the system is the fact, that the graph of the volt-ampere characteristic can be received in instantaneous meanings of welding current and voltage signals, measured during the welding process. The approach allows to estimate volt-ampere characteristic of supply source immediately after process completion without disconnecting it from the welding post.
