Abstract

Present embodiments include systems and methods for stick welding applications. In certain embodiments, simulation stick welding electrode holders may include stick electrode retraction assemblies configured to mechanically retract a simulation stick electrode toward the stick electrode retraction assembly to simulate consumption of the simulation stick electrode during a simulated stick welding process. In addition, in certain embodiments, stick welding electrode holders may include various input and output elements that enable, for example, control inputs to be input via the stick welding electrode holders, and operational statuses to be output via the stick welding electrode holders. Furthermore, in certain embodiments, a welding training system interface may be used to facilitate communication and cooperation of various stick welding electrode holders with a welding training system.
