DIAGNOSTIC SYSTEM FOR A WELD CONTROLLER

摘要

A weld controller is coupled to a communications network which has an operator interface unit for monitoring and controlling the weld controlle r and other weld controllers on the network. A time of day clock provides a chronological reference to tag weld current and voltage data and other data when it occurs for storage in its memory which is also accessible by the operator interface unit for storing in said system database. A memo pad in the weld controller is also accessible to the network for storing data for diagnostic purposes, said data including faults, events, and other operation al data. The data can then be displayed, edited, and stored by the operator interface's program.
