Classification: CPC B | IPC B

Claim 10:
11. The welding-type power supply of claim 1:
wherein the communications circuitry is configured to transmit a third communication to the welding device, wherein the third communication comprises a command to the welding device to close the switch to complete the measurement circuit;
wherein the control circuitry is configured to control the power conversion circuitry to:
output a second signal at the controlled voltage to the measurement circuit; and
after the third communication, limit a current of the second signal to a second threshold level;

wherein the communications circuitry is further configured to receive a fourth communication from the welding device indicating a plurality voltage measurements during the second signal; and
wherein the control circuitry is configured to determine an impedance of the second portion of the weld circuit based on the determined resistance, a plurality of current measurements, and the plurality voltage measurements.
