Life of the patent
3 dated eventsAbstract
Embodiments of a pendant associated with a multi-process welding power supply that allows a user to switch processes and reverse an output polarity while located remotely from a power supply unit are provided. Certain embodiments include a pendant with a wire spool and wire feeder drive circuitry that is configured to activate spooling during MIG welding. Control circuitry that may include processing circuitry and memory is provided. The control system may disable redundant controls on the power supply unit user interface when the power supply unit is connected to the pendant via a supply cable. Additionally, the control system may set the process, set the polarity, enable or disable a wire feed, and enable or disable gas flow according to inputs received via a user interface on either the power supply unit or the pendant.
