Transients in arc welding generators

THE TRANSIENT behavior of an arc welding generator, it is generally agreed, has considerable influence on the nature of the weld produced, both as to quality of weld and ease of manipulation. Several designs of generators have recently appeared which have been built to meet these requirements. This paper deals with the theory of armature and field current transients in such generators, giving the mathematical analysis and experimental results. From the tests were obtained oscillograms showing the effect of variation in the armature and field circuit inductance, and the mutual inductance between them.
