Welding system with power line communication

James Francis Rappl, +6 more
TLDR
In this article, a multi-process welding power supply is communicatively coupled to a pendant via an auxiliary conduit that facilitates the exchange of data and power between components of the welding system.
Abstract: 
Various welding systems that provide communication over auxiliary or weld power lines are provided. The disclosed embodiments may include a multi-process welding power supply that is communicatively coupled to a pendant via an auxiliary conduit that facilitates the exchange of data and power between components of the welding system. In some embodiments, the pendant may also include auxiliary outlets that allow an operator to power auxiliary devices at the weld location. The disclosed embodiments further include a pendant with a wire spool and wire feeder drive circuitry that is configured to activate spooling during MIG welding. Embodiments are provided that also allow for bidirectional data communication over a power line in networked welding systems.
