1. A welding diagnostic device for use with a welding machine during a welding process, comprising:
a welding data interface configured to receive a welding voltage from a welding machine during a welding process;
viewable identifiers configured to visually indicate metal transfer modes during said welding process;
a voltage sensor configured to read said welding voltage from said welding data interface; and
a data acquisition system configured to, during said welding process, determine a transfer mode threshold based solely on an average of said welding voltage, determine a metal transfer mode of said welding process based on transitions of said welding voltage across said threshold, and provide a sensory indication thereof, wherein said voltage sensor is configured to provide said welding voltage to said data acquisition system.
