Engine driven welding power supply with dig circuit

摘要

An engine driven welding power supply including a welding output winding, and a dig output winding is disclosed. The welding output winding has a welding output with a welding V-A curve of a first slope, in a welding range and below the welding range. The dig output winding has a dig output with a dig V-A curve of a second slope below the welding range. The second slope is less steep than the first slope. An output circuit is connected to receive and combine the welding and dig outputs to provide a power supply output.
