Welding power supplies, wire feeders, and systems to measure a weld circuit resistance via communications over the weld circuit are disclosed. An example welding-type power supply includes: a power converter configured to: convert input power to output a current pulse via a weld circuit; and convert the input power to output welding-type power via the weld circuit; a voltage monitor configured to measure a power supply output voltage of the current pulse; a receiver circuit configured to receive, via the weld circuit, a communication comprising a second voltage measurement; and a controller configured to: determine a resistance of a portion of the weld circuit based on the power supply output voltage measurement, the second voltage measurement, and a weld circuit current measurement; and control the power converter to convert the input power to output the welding-type power based on a weld voltage setpoint and the impedance.

Welding device

Disclosed example power supplies, user interfaces, and methods are provided for intuitive or automatic control of welding parameter output ranges. The disclosed systems and methods provide tools for setup of configurable and/or default settings for a welding power source and/or wire feeder. Weld settings include upper and lower limits for an operating range corresponding to one or more welding parameters, such that a welding parameter value is bound by the upper and lower limits during a welding operation. In some examples, the operating range, and the corresponding upper and lower limits, are calculated or determined based on a selected range tolerance.

Systems and methods for automatic control of welding parameter output ranges

Welding power supplies, wire feeders, and systems to measure a weld circuit resistance via communications over the weld circuit

A system includes sensors for transmitting data on a low power and/or short range transmission link, and one or more coordinators in wireless communication with the sensors. The coordinators convert signals received via the low power and/or short range transmission link to a longer range transmission link. A base station is in wireless communication with the coordinators via the longer range transmission link so that data generated by the sensors is transferred to the base station via the coordinators.
