Data transferring method and device for electric fusion welding device

摘要

A host computer matches indexes of work data stored in an electro-fusion apparatus against indexes of work data transferred to the host computer. Based on results of the matching, the host computer requests the electro-fusion apparatus for transmission of yet untransferred work data. The time required to transfer work data is reduced by eliminating the need to transfer the work data already transferred from the electro-fusion apparatus to the host computer.
