Abstract: Apparatus, systems, and/or methods for mitigating audible noise generated by a welding-type power supply are disclosed. In some examples, the switching frequency of the welding-type power supply may be changed to a frequency that is outside the audible range for humans. This strategy takes advantage of the fact that the observed audible noise is generated by vibrating components within the welding-type power supply that vibrate at a frequency related to the switching frequency. Other noise mitigation strategies include dithering and deactivation of portions of the welding-type power supply that vibrate to generate the audible noise.

Abstract: Systems and methods are provided for utilizing in-line wire feeders. A welding-type system may include an in-line wire feeder device configured to feed electrode wire from a wire source. The in-line wire feeder device may include an in-line wire feeding mechanism, may be a physically separate component from both of a second wire feeder device and a welding-type torch, and may be connected in series with the second wire feeder device. The in-line wire feeder device may control feeding of the electrode wire from a wire source, with the controlling including causing the second wire feeder device to feed the electrode wire from the wire source until the electrode wire reaches the in-line wire feeding mechanism, and then afterwards deactivating at least a feeding function of the second wire feeder device, and causing the in-line wire feeding mechanism to take over feeding of the electrode wire from the wire source.
