System and device operating using a welding power bus

A welding system comprising:

• a welding power supply comprising:
• power conversion circuitry configured to convert input power to output power;
• a set of terminals configured to provide the output power to a welding torch when the welding torch is electrically connected to the set of terminals, and to provide an adapted output power to a non-welding device when the non-welding device is electrically connected to the set of terminals;
• a weld cable communication (WCC) module coupled to the set of terminals and configured to control communication of data via a weld cable connecting a type of device to the set of terminals, wherein the type of device comprises the welding torch or the non-welding device;
• and
• control circuitry coupled to the WCC module, wherein the control circuitry is configured to receive the data from WCC module, to determine the type of device based on the data received from the set of terminals and the WCC module, to adapt the output power to the adapted output power to power the non-welding device based at least in part on an identity of the non-welding device when the non-welding device is the type of device being used, and to provide the output power to the welding torch when the welding torch is the type of device being used.
