Abstract: Welding power supplies, wire feeders, and systems to measure a weld cable voltage drop are disclosed. Example welding-type power supplies include a power converter configured to convert input power to output welding-type power to a remote device via a weld cable; a reference conductor connected between the power supply and the remote device; a voltage monitor configured to determine a first voltage between the weld cable and the reference conductor while substantially zero current is being conducted through the reference conductor; and a receiver circuit configured to receive a second voltage between the weld cable and the reference conductor from the remote device.

Abstract: A welding-type power supply includes a controller, bus (that can, but need not be preregulated), and an output converter. The controller has a preregulator control output and an output converter control output. The controller may receive bus feedback indicative of a plurality of bus voltages. A bus voltage balancing module in the converter includes a scaled correction module responsive to the bus feedback signal, and the converter control output is responsive to the bus voltage balancing module. The controller may receive load feedback indicative of a load output, have a bus voltage balancing module that includes a load proportional gain module responsive to the load.

Abstract: Systems and methods for pairing welding devices in a welding system. In one method, the method includes sending a pairing request from a first welding device to a second welding device. The method also includes receiving, at the first welding device, a response to the pairing request from the second welding device. The second welding device is physically connected to the first welding device. The pairing request or the response includes a change in welding power, welding consumables, or any combination thereof The method includes pairing the first welding device and the second welding device after the first welding device receives the response to the pairing request from the second welding device.
